摘要：	To construct a heavy vehicle simulation model, it is necessary to obtain vehicle parameters. A sensitivity analysis has been completed that studies the effects of +/- 15% variations in vehicle parameters on rear wheel dynamic load coefficients and maximum vertical rear wheel/pavement forces. Four speeds and road profiles of low, medium, and high roughness were considered. Variations in wheelbase, vehicle curb weight, and payload weight were observed to cause significant variations in values of rear wheel dynamic load coefficients and rear wheel peak forces. In addition, inaccuracies in determination of rear suspension spring rate, rear suspension unsprung weight, and rear tire spring rate were shown to have a significant effect on rear wheel dynamic load coefficients, but not on rear wheel peak forces.
