2.32.           "Cantrail" means the longitudinal structural part of the bodywork above the side windows including the curved transition to the roof structures.  In the rollover test the cantrail (in the case of a double deck coach, the cantrail of the upper deck) hits the ground first.

 

2.33.           "Waistrail" means the longitudinal structural part of the bodywork below the side windows. In the rollover test the waistrail (in the case of a double deck coach, the waistrail of the upper deck) may be the second area to contact the ground after initial deformation of the vehicle cross-section.

5.                GENERAL SPECIFICATIONS AND REQUIREMENTS     

 

5.1.             Requirements

 

                   The superstructure of the vehicle shall have the sufficient strength to ensure that the residual space during and after the rollover test on complete vehicle is unharmed.  That means:

 

5.1.1.          no part of the vehicle which is outside the residual space at the start of the test (e.g. pillars, safety rings, luggage racks) shall intrude into the residual space during the test.  Any structural parts, which are originally in the residual space (e.g. vertical handholds, partitions, kitchenettes, toilets) shall be ignored when evaluating the intrusion into the residual space.

 

5.1.2.          no part of the residual space shall project outside the contour of the deformed structure.
The contour of the deformed structure shall be determined sequentially, between every adjacent window and/or door pillar.  Between two deformed pillars the contour shall be a theoretical surface, determined by straight lines, connecting the inside contour points of the pillars which were the same height above the floor level before the rollover test (see Figure 1).

 

MT%20Fig

Figure 1 - Specification of the contour of the deformed structure

 

 

5.2.             Residual space

 

                   The envelope of the vehicle's residual space is defined by creating a  vertical transverse plane within the vehicle which has the periphery described in Figures 2(a) and 2(c), and moving this plane through the length of the vehicle (see Figure 2(b)) in the following manner:

 

5.2.1.          the SR point is located on the seat-back of each outer forward or rearward facing seat (or assumed seat position), 500 mm above the floor under the seat, 150 mm from the inside surface of the side wall.  No account shall be taken of wheel arches and other variations of the floor height.  These dimensions shall also be applied in the case of inward facing seats in their centre planes.

 

5.2.2.          If the two sides of the vehicle are not symmetrical in respect of floor arrangement and, therefore, the height of the SR points are different, the step between the two floor lines of the residual space shall be taken as the longitudinal vertical centre plane of the vehicle (see Figure 2(c));

 

5.2.3.          the rearmost position of the residual space is a vertical plane 200 mm behind the SR point of the rearmost outer seat, or the inner face of the rear wall of the vehicle if this is less than 200 mm behind that SR point.

 

                   The foremost position of the residual space is a vertical plane 600 mm in front of the SR point of the foremost seat (whether passenger, crew, or driver) in the vehicle set at its fully forward adjustment.

 

If the rearmost and foremost seats on the two sides of the vehicle are not in the same transverse planes, the length of the residual space on each side will be different;

5.2.4.          The residual space is continuous in the passenger, crew and driver compartment(s) between its rearmost and foremost plane and is defined by moving the defined vertical transverse plane through the length of the vehicle along straight lines through the SR points on both sides of the vehicle.  Behind the rearmost and in front of the foremost seat's Sr point the straight lines are horizontal.

 

5.2.5.          The manufacturer may define a bigger residual space than is required for a given seat arrangement, to simulate a worst case in a group of vehicle types to allow for future design development.

Text Box: Figure 2 - Specification of residual spaceMT%20Fig

 

 

 
5.3.             Specification of rollover test on a complete vehicle as the basic approval method

 

                   The rollover test is a lateral tilting test (see Figure 3), specified as follows:

 

5.3.1.          The complete vehicle is standing on the tilting platform, with blocked suspension and is tilted slowly to its unstable equilibrium position.  If the vehicle type is not fitted with occupant restraints it will be tested at unladen kerb mass.  If the vehicle type is fitted with occupant restraints it will be tested at total effective vehicle mass;

 

5.3.2.          The rollover test starts in this unstable vehicle position with zero angular velocity and the axis of rotation runs through the wheel-ground contact points.  At this moment the vehicle is characterized by the reference energy ER (see paragraph 3.2.2.1. and Figure 3);

 

5.3.3.          The vehicle tips over into a ditch, having a horizontal, dry and smooth concrete ground surface with a nominal depth of 800 mm;

 

5.3.4.          The detailed technical specification of the rollover test on a complete vehicle as the basic approval test is given in Annex 5.

 

 

        Figure 3 -   Specification of the rollover test on a complete vehicle showing the path of
the centre of gravity through the starting, unstable equilibrium, position

 

5.4.             Specifications of equivalent approval tests

 

                   Instead of the rollover test on a complete vehicle, at the discretion of the manufacturer, one of the following equivalent approval test methods can be chosen:

 

5.4.1.          Rollover test on body sections which are representative of the complete vehicle, in accordance with the specifications of Annex 6.

 

5.4.2.          Quasi-static loading tests of body sections in accordance with the specifications of Annex 7.

 

5.4.3.          Quasi-static calculations based on the results of component tests in accordance with the specifications of annex 8.

 

5.4.4.          Computer simulation - via dynamic calculations - of the basic rollover test on a complete vehicle in accordance with the specifications of Annex 9.

5.4.5.          The basic principle is that the equivalent approval test method must be carried out in such a way that it represents the basic rollover test specified in Annex 5.  If the equivalent approval test method chosen by the manufacturer cannot take account of some special feature or construction of the vehicle (e.g. air-conditioning installation on the roof, changing height of the waist rail, changing roof height) the complete vehicle may be required by the technical service to undergo the rollover test specified in Annex 5.

5.5.             Testing of articulated vehicles

 

                   In the case of an articulated vehicle, each rigid section of the vehicle shall comply with the general requirement specified in paragraph 5.1.  Each rigid section of an articulated vehicle may be tested separately or in combination as described in Annex 5, paragraph 2.3, or in Annex 3, paragraph 2.6.7.

 

5.6.             Direction of rollover test

 

                   The rollover test shall be carried out on that side of the vehicle which is more dangerous with respect to the residual space.  The decision is made by the technical service on the basis of the manufacturer's proposal, considering at least the following:

 

5.6.1.          the lateral eccentricity of the centre of gravity and its effect on the reference energy in the unstable, starting position of the vehicle, see paragraph 3.2.2.1;

 

5.6.2.          the asymmetry of the residual space, see paragraph 5.2.2

 

5.6.3.          the different, asymmetrical constructional features of the two sides of the vehicle, and the support given by partitions or inner boxes (e.g. wardrobe, toilet, kitchenette).  The side with the lesser support shall be chosen as the direction of the rollover test.

 

6.                MODIFICATION AND EXTENSION OF APPROVAL OF A VEHICLE TYPE

 

6.1.             Every modification of the approved vehicle type shall be advised to the Administrative Department which granted the type approval.  The Administrative Department may then either,

 

6.1.1.          agree that the modifications made are unlikely to have an appreciable effect and that in any case the modified vehicle type still complies with the requirements of this Regulation and constitutes part of a group of vehicle types together with the approved vehicle type; or

 

6.1.2.          require a further test report from the technical service responsible for conducting the tests to prove that the new vehicle type complies with the requirements of this Regulation and constitutes part of a group of vehicle types together with the approved vehicle type; or

 

6.1.3.          refuse the extension of approval and require a new approval procedure to be carried out.

6.2.             The decisions of the Administrative Department and the technical service shall be based on the threefold criteria of the worst case:

 

6.2.1.          the structural criterion means whether the superstructure is changed or not (see Annex 4).  If no change, or the new superstructure is stronger, this is favourable.

 

6.2.2.          the energy criterion means whether the reference energy is changed or not.  If the new vehicle type has the same or smaller reference energy than the approved one, this is favourable.

 

6.2.3.          residual space criterion is based on the envelope surface of the residual space.  If the residual space of the new vehicle type is everywhere within the approved case residual space, this is favourable.

 

6.3.             If all three criteria described in paragraph 6.2. are changed favourably, the extension of the approval shall be granted without further investigation.

 

                   If all of three answers are unfavourable, a new approval procedure is required.

 

                   If the answers are mixed, further investigations (tests, calculation, structural analysis, for example) will be required.  These investigations shall be determined by the technical service cooperating with the manufacturer.

 

6.4.             Confirmation or refusal of approval, specifying the alterations, shall be notified by the procedure specified in paragraph 4.3. above to the Parties to the Agreement which apply this Regulation.

 

6.5.             The Administrative Department  issuing the extension of approval shall assign a series number to each communication form drawn up for such an extension.

 

7.               CONFORMITY OF PRODUCTION

 

7.1.             The conformity of production procedure shall comply with those set out in the Agreement, Appendix 2, (E/ECE/324-E/ECE/TRANS/505/Rev.2).

 

7.2.             Every vehicle approved under this regulation shall be so manufactured as to conform to the type approved by meeting the requirements set out in paragraph 5. above.  Only those elements which are nominated by the manufacturer as part of the superstructure shall be checked.

 

7.3.             The normal frequency of inspections authorised by the Administrative Department shall be once every two years.  If non-conformity is discovered in the course of one of these visits, the Administrative Department may increase the visit frequency to re-establish the conformity of production as rapidly as possible.

 

8.                PENALTIES FOR NON-CONFORMITY OF PRODUCTION

 

8.1.             The approval granted in respect of a vehicle type pursuant to this Regulation may be withdrawn if the requirements laid down in paragraph 7. above are not complied with.

 

8.2.             If a party to the Agreement applying this Regulation withdraws an approval it has previously granted, it shall forthwith so notify the other Contracting Parties applying this Regulation, by means of a copy of the approval form bearing at the end, in large letters, the signed and dated annotation "APPROVAL WITHDRAWN".

 

9.                PRODUCTION DEFINITELY DISCONTINUED

 

                   If the holder of the approval completely ceases to manufacture a type of vehicle approved in accordance with this Regulation, he shall so inform the Administrative Department which granted the approval.  Upon receiving the relevant communication, that Administrative Department shall inform the other Parties to the Agreement applying this Regulation by means of a copy of the approval form bearing at the end, in large letters, the signed and dated annotation "PRODUCTION DISCONTINUED".

ARRANGEMENT OF THE APPROVAL MARK

(See paragraph 4.4. of this Regulation)

 

Text Box:  Text Box: 022431

 

 

The above approval mark affixed to a vehicle shows that the vehicle type concerned has, with regard to the strength of the superstructure, been approved in the United Kingdom (E11) pursuant to Regulation No. 66 under approval number 022431. The first two digits of the approval number indicate that the approval was granted in accordance with the requirements of the 02 series of amendments to Regulation No. 66.

 

 

 


Annex 3

 

Determination of THE centre of gravity OF THE vehicle

 

1.                General principles

1.1.             The reference and the total energy to be absorbed in the rollover test depend directly on the position of the vehicle's centre of gravity position.  Therefore, its determination should be as accurate as practicable.  The method of measurement of dimensions, angles and load values, and the accuracy of measurement shall be recorded for assessment by the technical service.  The following accuracy of measuring apparatus is required:

 

-  for measurements less than 2000 mm,                  accuracy of          ± 1 mm

-  for measurements greater than 2000 mm,             accuracy of          ± 0.05 per cent

-  for measured angles,                                             accuracy of          ± 1 per cent

-  for measured load values                                      accuracy of          ± 0.2 per cent

The wheel-base(s) and the distance between the centres of the footprint of the wheel(s) at each axle (the track of each axle) shall be determined from the manufacturer's drawings.

 

1.2.             Blocked suspension is specified as the condition for determining centre of gravity and for carrying out the actual rollover test.  The suspension shall be blocked in the normal operating position as defined by the manufacturer

 

1.3.             The position of the centre of gravity is defined by three parameters:

 

1.3.1.          longitudinal distance (l1) from the centre line of front axle

 

1.3.2.          transverse distance (t) from the vertical longitudinal central plane of the vehicle.

 

1.3.3.          vertical height (h0) above the flat horizontal ground level when the tyres are inflated as specified for the vehicle

 

1.4.             A method for determining l1, t, h0, using load cells is described here.  Alternative methods using lifting equipment and/or tilt tables for example may be proposed by the manufacturer to the technical service who will decide whether the method is acceptable based on its degree of accuracy.

 

1.5.             The centre of gravity position of the unladen vehicle (unladen kerb mass Mk) shall be determined by measurements.

 

1.6.             The centre of gravity position of the vehicle with total effective mass (Mt) may be determined:

 

1.6.1.          by measuring the vehicle in total effective mass condition, or


1.6.2.          by using the measured centre of gravity position in the unladen kerb mass condition and considering the effect of the total occupant mass.

 

1.6.3.          In the case of a double deck vehicle, the mass of the passengers both on the lower and upper deck seats shall be taken into account.

 

2.                Measurements

 

2.1.             The position of the vehicle's centre of gravity shall be determined in the unladen kerb mass condition or the total effective vehicle mass condition as defined in paragraphs 1.5. and 1.6.  For the determination of the position of the centre of gravity in the total effective vehicle mass condition, the individual occupant mass (factored by the constant, k = 0.5) shall be positioned and rigidly held 100 mm above and 100 mm forward of the R point (which is defined in Regulation No. 21, annex 5) of the seat.

 

2.2.             The longitudinal (l1) and transverse (t) coordinates of centre of gravity shall be determined on a common horizontal ground (see Figure A3.1) where each wheel or twinned wheel of the vehicle is standing on an individual load cell.  Each steered wheel shall be set to its straight-ahead position.

 

2.3.             The individual load-cell readings shall be noted simultaneously and shall be used to calculate the total vehicle mass and centre of gravity position.

 

2.4.             The longitudinal position of the centre of gravity relative to the centre of the contact point of the front wheels (see Figure A3.1) is given by,

 

where:

 

P1  =  reaction load on the load cell under the left-hand wheel of the first axle

P2  =  reaction load on the load cell under the right-hand wheel of the first axle

P=  reaction load on the load cell under the left-hand wheel(s) of the second axle

P=  reaction load on the load cell under the right-hand wheel(s) of the second axle

P5   =  reaction load on the load cell under the left-hand wheel(s) of the third axle

P6   =  reaction load on the load cell under the right-hand wheel(s) of the third axle

Ptotal  =  (P1+P2+P3+P4+P5+P6)  =  Mk  unladen kerb mass; or,

                                                  =  Mt    total effective vehicle mass, as appropriate

L1  =  the distance from centre of wheel on 1st axle to centre of wheel on second axle

L2  =  the distance from centre of wheel on 1st axle to centre of wheel on third axle, if

          fitted

 

Figure%20A3

 

Figure A3.1 - Longitudinal position of the centre of gravity

 

2.5.             The transverse position (t) of the vehicle's centre of gravity relative to its longitudinal vertical centre plane  (see figure A3.2) is given by,

 

where:

 

T1  =      distance between the centres of the footprint of the wheel(s) at each end of the first axle

T2  =      distance between the centres of the footprint of the wheel(s) at each end of the second axle

T3  =      distance between the centres of the footprint of the wheel(s) at each end of the third axle

 

This equation assumes that a straight line can be drawn through the centre points of  T1, T2, T3.  If this is not the case then a specialised formula will be required.

 

If the value of (t) is negative, then the centre of gravity of the vehicle is situated to the right of the centreline of the vehicle.


 

Figure%20A3

 

Figure A3.2 - Transverse position of centre of gravity

 

 

2.6.             The height of the centre of gravity (h0) shall be determined by tilting the vehicle longitudinally and using individual load-cells at the wheels of two axles.

 

2.6.1.          Two load-cells shall be positioned on a common horizontal plane, to receive the front wheels.  The horizontal plane shall be at sufficient height above the surrounding surfaces that the vehicle can be tilted forward to the required angle (see paragraph 2.6.2. below) without its nose touching that surface.

 

2.6.2.          A second pair of load-cells shall be placed in a common horizontal plane on top of support structures, ready to receive the wheels of the second axle of the vehicle.  The support structures shall be sufficiently tall to generate a significant angle of inclination a (> 20°) for the vehicle.  The greater the angle, the more accurate will be the calculation – see figure A3.3.  The vehicle is repositioned on the four load-cells, with the front wheels chocked to prevent the vehicle rolling forward.  Each steered wheel shall be set to its straight-ahead steer position.

 

2.6.3.          The individual load-cell readings shall be noted simultaneously and shall be used to check the total vehicle mass and centre of gravity position.

 

2.6.4.          The inclination of the tilting test shell be determined by the equation (see figure A3.3)

 

where:

 

H  =     height difference between the footprints of the wheels of the first and second axles

L1  =    the distance from centre of wheel's first and second axles

 

2.6.5.          The unladen kerb mass of the vehicle shall be checked as follows:

 

Ftotal = F1+F2+F3+F4 º Ptotal º Mk

 


where:

 

F1  =  reaction load on the load cell under the left hand wheel of the first axle

F2  =  reaction load on the load cell under the right hand wheel of the first axle

F3  =  reaction load on the load cell under the left hand wheel of the second axle

F4  =  reaction load on the load cell under the right hand wheel of the second axle

 

If this equation is not fulfilled the measurement shall be repeated and/or the manufacturer shall be asked to modify the value of the unladen kerb mass in the technical description of the vehicle.

 

2.6.6.          The height (ho) of the vehicle centre of gravity is given by:

 

where:

r  =  height of wheel centre (on first axle) above the load cell top surface

 

2.6.7.                    If the articulated vehicle is tested in separate sections, the centre of gravity position shall be established separately for each section.

Annex 4

 

VIEWPOINTS ON THE STRUCTURAL DESCRIPTION OF THE SUPERSTRUCTURE

 

1.                General principles

 

1.1.             The manufacturer shall define unambiguously the superstructure of the bodywork (see figure A4.1, for example) and shall state:

 

1.1.1.          which bays contribute to the strength and energy absorption of the superstructure;

 

1.1.2.          which connecting elements between the bays contribute to the torsional stiffness of the superstructure;

 

1.1.3.          the mass distribution among the nominated bays;

 

1.1.4.          which elements of the superstructure are assumed as rigid parts.

 

 

 

 

 

Figure A4. 1 - Derivation of the superstructure from the bodywork

 

 

 

 

1.2.             The manufacturer shall supply the following information about the elements of the superstructure:

 

1.2.1.          drawings, with all the significant geometrical measurements necessary to produce the elements and to evaluate any change or alteration of the element;

 

1.2.2.          the material of the elements referred to national, or international standards;

 

1.2.3.          the joint technology between the structural elements (riveted, bolted, glued, welded, type of welding, etc.).

 

1.3.             Every superstructure shall have at least two bays:  one in front of the centre of gravity and one behind the centre of gravity.

 

1.4.             No information is required about any elements of the bodywork, which are not parts of the superstructure.

 

2.                Bays

 

2.1.             A bay is defined as a structural section of the superstructure forming a closed loop between two planes which are perpendicular to the vertical longitudinal centre plane (VLCP) of the vehicle.  A bay contains one window (or door) pillar on each side of the vehicle as well as side wall elements, a section of the roof structure and a section of the floor and underfloor structure.  Every bay has a transverse centre plane (CP) perpendicular to the VLCP of the vehicle and passing through the centre points (Cp)
of the window-pillars (see figure A4.2)

 

2.2.             The Cp is defined as a point at half window height and halfway across the pillar width.  If the Cp of the left-side and right- side pillars of a bay are not in the same transverse plane, the CP of the bay is set halfway between the transverse planes of the two Cp's.

 

2.3.             The length of a bay is measured in the direction of the longitudinal axis of the vehicle, and is determined by the distance between two planes perpendicular to the VLCP of the vehicle.  There are two limits which define the length of a bay:  the window (door) arrangement, and the shape and construction of the window (door) pillars.)

 

Figure%20A4

 

Figure A4. 2 - Definition of length of bays

 

 

2.3.1.          The maximum length of a bay is defined by the length of the two neighbouring window (door) frames

 

 

where:

a = the length of the window (door) frame behind the jth pillar, and

                                  i)          b = the length of the window (door) frame in front of the jth pillar

 

If the pillars on opposite sides of the bay are not in one transverse plane, or the window frames on each side of the vehicle have different lengths (see figure A4.3), the overall length, Wj of the bay is defined by:

 

 

                                ii)          where:

                              iii)          amin   =  the smaller value of aright side  or  aleft side

                                 iv)           bmin  =  the smaller value of bright side  or  bleft side   

 L      =  the longitudinal offset between the centrelines of the pillars

on the left and right sides of the vehicle

 

 

Figure%20A4

 

Figure A4. 3 - Definition of bay length when pillars on each side of the bay

are not in one transverse plane

 

 

2.3.2.          The minimum length of a bay shall include the whole window pillar (including its inclination, corner radii, etc.).  If the inclination and corner radii exceed half the length of the adjacent window then the next pillar shall be included in the bay.

 

2.4.             The distance between two bays shall be defined as the distance between their CP's.

 

2.5.             The distance of a bay from the centre of gravity of the vehicle shall be defined as the perpendicular distance from its CP to the vehicle centre of gravity.

 

3.                Connecting structures between the bays

 

3.1.             the connecting structures between bays shall be clearly defined in the superstructure.  These structural elements fall into two distinct categories:

 

3.1.1.          The connecting structures which form part of the superstructure.  These elements shall be identified by the manufacturer, in this design submission: they include:

 

3.1.1.1.       side-wall structure, roof structure, floor structure, which connect several bays,

 

3.1.1.2.       structural elements which reinforce one or more bays; for example, boxes under seats, wheel arches, seat structures connecting side-wall to floor, kitchen, wardrobe and toilet structures.

 


3.1.2.          The additional elements which do not contribute to the structural strength of the vehicle but which may intrude into the residual space, for example: ventilation ducts, hand luggage boxes, heating ducts.

4.                Mass distribution

 

4.1.             The manufacturer shall clearly define the portion of the mass of the vehicle attributed to each of the bays of the superstructure.  This mass distribution shall express the energy absorbing capability and load bearing capacity of each bay. The following requirements shall be met when defining the distribution of mass:

 

4.1.1.          the sum of the masses attributed to each bay shall be related to the mass M of the complete vehicle:

 

                  

where:

 

mj  =  the mass attributed  to the jth bay

n    =  the number of bays in the superstructure

M  =  Mk, unladen kerb mass; or,

      =  Mt, total effective vehicle mass, as appropriate    

 

4.1.2.          the centre of gravity of the distributed masses shall be in the same position as the centre of gravity of the vehicle:

 

 

where:

 

lj  =  the distance of the jth bay from the centre of gravity of the vehicle

       (see paragraph 2.3.).

lj  is positive, if the bay is in front of the centre of gravity and negative if it is

behind it.

 

4.2.             The mass " mj" of each bay of the superstructure shall be defined by the manufacturer, as follows:

 

4.2.1.          the masses of the components of the "jth" bay shall be related to its  mass "mj" by:

 

where:

mjk  =  the mass of each component of the bay

s      =  the number of individual masses on the bay

4.2.2.          the centre of gravity of the component masses of a bay shall have the same transverse position inside the bay as the bay's centre of gravity (see figureA4.4):

 

where:

yk  =  the distance of the kth mass component of the bay from the axis "Z" (see figure A4.4).

yk         will have a positive value on one side of the axis and a negative value on the other side.

zk  =  the distance of the kth mass component of the bay from the axis "Y",

zk         will have a positive value on one side of the axis and a negative value on the other side.

 

4.3.             In the case where occupant restraints are part of the vehicle specification, the occupant mass attributed to a bay shall be attached to that part of the superstructure which is designed to absorb seat and occupant loadings.

Annex 5

 

ROLLOVER TEST AS THE BASIC APPROVAL METHOD

2.                Preparation of test vehicle

 

2.1.             The vehicle to be tested need not be in a fully finished, "ready for operation" condition. Generally, any alteration from the fully finished condition is acceptable if the basic features and behaviour of the superstructure are not influenced by it.  The test vehicle shall be the same as its fully finished version in respect of the following:

 

2.1.1.          the position of the centre of gravity, the total value of vehicle mass (unladen kerb mass, or total effective vehicle mass where restraints are fitted) and the distribution and location of masses, as declared by the manufacturer.

 

2.1.2.          all of those elements which – according to the manufacturer - contribute to the strength of the superstructure shall be installed in their original position (see Annex 4 to this Regulation).

 

2.1.3.          elements, which do not contribute to the strength of the superstructure and are too valuable to risk damage (e.g. drive chain, dashboard instrumentation, driver's seat, kitchen equipment, toilet equipment, etc.) can be replaced by additional elements equivalent in mass and method of installation.  These additional elements must not have a reinforcing effect on the strength of superstructure.

 

2.1.4.          fuel, battery acid and other combustible, explosive or corrosive materials may be substituted with other materials provided that the conditions of paragraph 2.1.1. are met.

 

2.1.5.          In the case where occupant restraint devices are part of the vehicle type, a mass shall be attached to each seat fitted with an occupant restraint following one of these two methods, at the choice of the manufacturer:

 

2.1.5.1.            First  method: That mass shall be:

 

2.1.5.1.1          50 per cent of the individual occupant mass (Mmi) of 68 kg,

 

2.1.5.1.2.         placed to have its centre of gravity 100 mm above and 100 mm forward of the R point of the seat as defined in Regulation No. 21, Annex 5.

 

2.1.5.1.3.         fixed rigidly and securely so that it does not break away during the test.

 

2.1.5.2                 Second method:  That mass shall be

 

2.1.5.2.1     an anthropomorphic ballast with a mass of 68 kg and shall be restrained with a 2 point safety-belt.  The ballast must allow guiding and positioning for safety-belts.

 

2.1.5.2.2.    placed to have its centre of gravity and dimensioning according to figure A5.2.

 

2.1.5.2.3.        fixed rigidly and securely so that it does not break away during the test.

 

 

chest breadth ≈ 315-322 mm

waist breadth ≈ 290-310 mm

hip breadth ≈ 325-342 mm

 

Figure A5.2.-Dimensions for the anthropomorphic ballast

 

2.2.             The test vehicle shall be prepared as follows:

 

2.2.1.          tyres shall be inflated to the pressure prescribed by the manufacturer.

 

2.2.2.          the suspension system of the vehicle shall be blocked, i.e. the axles, the springs and the suspension elements of the vehicle shall be fixed in relation to the bodywork.  The floor height above the horizontal tilting platform shall be according to the manufacturer's

specification for the vehicle, dependent on whether it is loaded to unladen kerb mass or total vehicle mass.

 

2.2.3.          every door and opening window of the vehicle shall be closed but not locked.

 

2.3.             The rigid sections of an articulated vehicle may be tested separately or in combination.

 

2.3.1.          For testing the articulated sections as a combination, the sections of the vehicle shall  be fixed to each other in such a way that,

 

2.3.1.1.       there is no relative movement between them during the roll-over process.

 

2.3.1.2.       there is no significant change in mass distribution and centre of gravity positions.

 

2.3.1.3.       there is no significant change in the strength and deformation capability of the superstructure.

 

2.3.2.          For testing the articulated sections separately, the single-axle sections shall be attached to an artificial support which keeps them in fixed relation to the tilting platform during its movement from the horizontal to the point of roll-over.  This support shall meet the following requirements:

 

2.3.2.1.      it shall be fixed to the structure in such a way that it does not cause either reinforcement or extra additional load to the superstructure.

 

2.3.2.2.      it shall be constructed so that it does not suffer any deformation which could change the direction of the rollover of the vehicle.

 

2.3.2.3.       its mass shall be equal to the mass of those elements, parts of the articulated joint, which nominally belong to the section being tested, but which are not placed on it (e.g. turntable and its floor, handholds, rubber sealing curtains, etc.).

 

2.3.2.4.       its centre of gravity shall have the same height as the common centre of gravity of those parts which are listed in paragraph 2.3.2.3.

 

2.3.2.5.       it shall have an axis of rotation  parallel to the longitudinal axis of the multi-axle section of the vehicle, and passing through the points of  contact of the tyres of that section.

 

3.                Test procedure, test process

 

3.1.             The rollover test is a very rapid, dynamic process having distinguishable stages, should be taken into consideration when a rollover test, its instrumentation and  measurement are planned.

 

3.2.             The vehicle shall be tilted without rocking and without dynamic effects until it reaches unstable equilibrium and commences its rollover.  The angular velocity of the tilt platform shall not exceed 5 degrees/sec. (0.087 radians/sec).

 

3.3.             For inside observation high-speed photography, video, deformable templates, electrical contact sensors or other suitable means shall be used to determine that the requirements of paragraph 5.1. of this Regulation has been met.  This shall be verified at any places of the passenger, driver's and crew compartment where the residual space seems to be endangered, the exact positions being at the discretion of the technical service.  At least two positions, nominally at the front and rear of the passenger compartment(s) shall be used.

 

3.4.             Outside observation and recording of the rollover and deformation process is recommended, which means the following:

 

3.4.1.          two high-speed cameras - one at the front and another at the rear .  They should be located far enough from the front and rear wall of the vehicle to produce a measurable picture, avoiding wide-angle distortion in the shaded area, as  shown in figure A5.3a.

 

3.4.2.          the position of the centre of gravity and the contour of the superstructure (see figure A5.2b), is marked by stripes and bands to ensure correct measurements on the pictures.

4.1.3.          there is a clear statement of the position of centre of gravity in the tested vehicle which may be based on measurements carried out on the test vehicle when it is ready for test, or a combination of measurement (carried out on the fully finished vehicle type) and calculation based on the mass substitutions.

 

4.2.             The test report shall contain all the data (pictures, records, drawings, measured values, etc.) which show:

APPROVAL METHOD

 

1.                Additional data and information

 

This method of testing uses body sections as test units, each one built up from at least two bays of the vehicle under appraisal, connected together with representative structural elements.  If the manufacturer chooses this method of testing, the following additional information shall be supplied to the technical service, in addition to the data, and drawings listed in paragraph 3.2. of this Regulation:

1.1.             drawings of the body sections to be tested.

 

1.2.             energy values to be absorbed by the individual bays of the superstructure, as well as the energy values belonging to the body sections to be tested.

 

1.3.             verification of the energy requirement, see paragraph 4.2. below, upon completion of successful quasi-static loading tests of body sections.

 

2.                Preparation of body sections

 

2.1.             The manufacturer shall consider the requirements given in annex 6, paragraphs 3.1., 3.2., and 3.3., when designing and producing the body sections for test.

 

2.2.             The body sections shall be equipped with the residual space profile, at positions where it is considered that the pillars or other structural elements are likely to intrude as a result of the expected deformation.

 

3.                Test procedure

 

3.1.             Each body section to be tested shall be firmly and securely attached to the test bench through a rigid underframe structure in such a way that,

 

3.1.1.          local plastic deformation shall not occur around the attachment points;

 

3.1.2.          the location and method of attachment shall not inhibit the formation and working of expected plastic zones and hinges.

 

3.2.             For application of the load to the body section, the following rules shall be considered:

 

3.2.1.          the load  shall be evenly distributed on the cantrail, through a rigid beam, which is longer than the cantrail to simulate the ground in a rollover test, and which  follows the geometry of the cantrail.

 


3.2.2.          the direction of the applied load (see figure A7.1) shall be related to the longitudinal vertical centre plane of the vehicle and its inclination (a) shall be determined as follows:

where:

 

Hc  =  the cantrail height (in  mm) of the vehicle measured from the horizontal plane

          on which it is standing.

 

Figure%20A7

 

                                                                                               v)Figure A7.1 - Application of load to the body section

 

3.2.3.          the load shall be applied to the beam at the centre of gravity of the body section derived from the masses of its bays and the structural elements connecting them.  Using the symbols of Figure A.7.1, the position of the body section can be determined by the following formula:

where:

 

s  =    the number of the bays in the body section

mi  =  the mass of the ith bay

li    =   the distance of the centre of gravity of  the ith bay from a selected pivot point (the central plane of Bay(1) in figure A7.1)

lCG  =   the distance of the centre of gravity of the body section from the same selected pivot point.

 

3.2.4.          the load shall be increased gradually, taking measurements of the associated deformation at discrete intervals until the ultimate deformation (du ) when the residual space is invaded by one of the elements of the body section.

 

3.3.             When plotting the load-deflection curve:

 

3.3.1.          the frequency of measurement shall be such as to produce  a continuous curve (see figure A.7.2).

 

3.3.2.          the values of load and deformation shall be measured simultaneously.

 

3.3.3.          the deformation of the loaded cantrail shall be measured in the plane and direction of the applied load.

 

3.3.4.          both load and deformation shall be measured to an accuracy of ± 1 per cent.

4.  Evaluation of test results

 

4.1.             From the plotted load-deformation curve the actual energy absorbed by the body section (EBS) shall be expressed as the area below the curve (see figure A.7.2).Figure%20A7

Figure A7. 2  -   Absorbed energy for the body section, derived from the measured

load-deformation curve

 

4.2.             The minimum energy required to be absorbed by the body section (Emin) shall be determined as follows:

 

4.2.1.          the total energy (ET) to be absorbed by the superstructure is:

 

ET = 0.75 M g Dh

 

where:

 

M  =    Mk, unladen kerb mass of the vehicle if there are no occupant restraints; or,

Mt, total effective vehicle mass when occupant restraints are fitted,

g    =    gravitational constant,

Dh  =   the vertical movement (in metres) of the vehicle centre of gravity during a rollover

test, as determined in appendix 1 to this annex.

 

4.2.2.          the total energy "ET" shall be distributed among the bays of the superstructure in the proportions of their masses:

where:

Ei  =  the absorbed energy by the "ith" bay

mI  =  mass of the "ith" bay, as determined in annex 4, paragraph 4.1

 

4.2.3.          the minimum energy required to be absorbed by the body section (Emin) is the sum of the energy of the bays comprising the body section:

 

 

4.3.            The body section passes the loading test, if:

 

EBS  ³ Emin

 

In this case, all the bays which form that body section are considered to have passed the quasi-static loading test and these results can be quoted in future requests for approval provided that the component bays are not expected to carry a greater mass in the subsequent superstructure.

4.4.             The body section fails the loading test if:

 

EBS  < Emin

In this case all the bays which form that body section are considered to have failed the test even if the residual space is invaded in only one of the bays.

4.5.            The vehicle type shall be approved if all the required body sections pass the loading test.

 

5.    Documentation of body section quasi-static loading tests

 

The test report shall follow the form and content of Annex 6, paragraph 6.

 


Annex 7 - Appendix 1

 

DETERMINATION OF THE VERTICAL MOVEMENT OF THE CENTRE OF GRAVITY DURING ROLLOVER

 

The vertical movement (Dh) of centre of gravity related to the rollover test may be determined by the graphical method shown below.

 

1.                Using scaled drawings of the cross-section of the vehicle, the initial height (h1) of the centre of gravity (position 1) above the lower plane of the ditch is determined for  the vehicle standing at its point of unstable equilibrium on the tilting platform (see Figure A7.A1.1).

 

2.                Using the assumption that the vehicle cross-section rotates around the edge of the wheel supports, (point A in Figure A7.A1.1) the vehicle cross-section is drawn with its cantrail just touching the lower plane of the ditch (see Figure A7.A1.2).  In this position the height (h2) of the centre of gravity (position 2) relative to the lower plane of the ditch is determined.

Dh = h1 – h2

 

4.                If more than one body sections are tested and each body section has a different vertical movement (Dh), the vertical movement of centre of gravity (Dhi) shall be determined for each body section and the combined mean value (Dh) is taken as,

 

 

where:

 

Dhi  =  the vertical movement of the centre of gravity of the ith body section,

k        =  the number of body sections tested.

Annex 8 - Appendix 1

 

CHARACTERISTICS OF PLASTIC HINGES

 

1.                Characteristic curves

 

The general form of a Plastic Zone (PZ) characteristic curve is a non-linear load-deformation relationship measured on structural parts of the vehicle in laboratory tests.

Plastic Hinge characteristic curves are a bending moment (M) - rotational angle (j) relationship.  The general form of a PH characteristic curve is shown in Figure A.8. A.1.1

 

 

Figure%20A8

 

Figure A8. A1.1 - Characteristic curve for a plastic hinge

 

2.                      Aspects of deformation ranges

 

2.1.             The "measured range" of the PH characteristic curve is  the range of deformation over which measurements have been made.  The measured range may contain the fracture, and/or the rapid hardening range.  Only values of the PH characteristics which appear in the measured range shall be used in the calculation.

 

2.2.             The "working range" of the PH characteristic curve is the range covered by the calculation. 

 

The working range shall not exceed the measured range, and may contain the fracture, but not the rapid-hardening range.


2.3.             The PH characteristics to be used in the calculation shall contain the M-j curve in the measured range.

 

3.                Dynamic Characteristics

 

                   There are two kinds of PH and PZ characteristics:  quasi-static and dynamic.  The dynamic characteristics of a PH may be determined in two ways:

 

3.1.            by dynamic impact testing of the component.

 

3.2.             by using a dynamic factor Kd to transform the quasi-static PH characteristics.

This transformation means that    the values of the quasi-static bending moment may be increased by Kd.

 

For steel structural elements Kd  =  1.2 may be used without laboratory test.

9.                                          VERIFICATION OF STRENGTH OF SUPERSTRUCTURE BY CALCULATION

9.1.1                                A superstructure or sections may be shown to meet the requirement specified in clause 2.1 by a calculation method.

9.1.2                                If the structure is likely to be subject to deformations beyond the elastic limit of the materials used then the calculations shall simulate the behaviour of the structure when undergoing large plastic deformations.

9.1.3                                The test facility responsible for conducting the tests may be required to carry out test on joints or parts of the structure to verify the assumptions made in the calculation.

9.2                                      PREPARATIONS FOR CALCULATION

9.2.1                                Calculations cannot be started until the structure has been analysed and a mathematical model of it produced. This will define the separate members to be considered and identify the points at which plastic hinges may develop. The dimension of the members and the properties of materials used must be stated. Physical tests must be made on the hinge points to determine the force (moment of rotation) - deformation characteristics in the plastic mode as this is essential data for the calculations. The strain rate and the dynamic yield stress appropriate for this strain rate must be determined. If the calculation method will not indicate when a significant fracture will occur it will be essential to determine, by experiment separate analysis or appropriate dynamic tests that significant fractures will not occur. The assumed distribution of loading along the length of a vehicle shall be stated.

9.2.2                                The calculation method shall include the deformations up to the elastic limits of the materials followed by the identification of where plastic hinges will form and the subsequent formation of other plastic hinges unless the position and sequence of formation of plastic hinges is known from previous experience. The method shall accommodate the changes of geometry of the structure that take place, at least up to the stage where the deformations have passed the acceptable limits.

Unless otherwise approved for the purposes of demonstration of compliance to this rule it is acceptable for the computer programme to exceed the measured force (moment of rotation) as determined by physical test by 10%.

9.2.3                                The calculations shall simulate the energy and the direction of impact which would occur if that particular superstructure were to be submitted to the roll-over tests prescribed in clause 6. The validity of the calculation method shall have been established by comparison with the results of physical tests, which need not necessarily have been made in connection with the vehicle now being approved.

9.3                                      When a calculation method is used for a section of a complete structure, the same conditions shall apply as stated above for the complete vehicle.
