22.                                      STABILITY REQUIREMENT (LEM, LEP & LEG Vehicles only)

22.1.                                For LEM1, LEP1 & LEG1 vehicles the height of the centre of mass (h) must not exceed the horizontal distance from the centre of mass to the nearest roll axis (d) (See Figure 5).

22.2.                                For LEM2, LEP2 & LEG2 vehicles the height of the centre of mass (h) must not exceed one and a half times the horizontal distance from the centre of mass to the nearest roll axis (d) (See Figure 5).

22.3.                                Test procedure for determining the vehicle’s centre of mass

22.3.1.                          Unless otherwise ‘Approved’, the location of the vehicle’s centre of mass must be determined by the method described below.

22.3.2.                          Transverse location

22.3.2.1.                    The transverse location of the centre of mass can be taken to be located along the vehicle’s longitudinal centreline.

22.3.3.                          Longitudinal location (See Figure 3)

22.3.3.1.                    The longitudinal location (L) of the centre of mass, from the centre line of the front ‘Axle’, is determined from the formula

where:

W is the wheelbase

R is the rear ‘Axle Load’ on the tyre(s) with the vehicle in the ‘Maximum Loaded Test Mass’ condition

F is the front ‘Axle Load’ on the tyre(s) with the vehicle in the ‘Maximum Loaded Test Mass’ condition
