An algorithm has been developed to compute a vehicle's center of gravity (CG) height utilizing the capability of the B400T Heavy Duty Plate Brake Tester. By measuring brake force, static weight and dynamic weight of each axle during a service brake stop and inputting the vehicles wheelbase, the CG height of a two-axle vehicle can be easily calculated using the dynamic weight transfer formula. Using this calculated CG height value and the wheel track width, the Static Stability Factors (SSF), or rollover propensity of the vehicle can be estimated.
