INFLUENCE OF VEHICLE PARAMETERS ON THE IN-MOTION PERFORMANCE OF MOTOR VEHICLES

UNTERSUCHUNG DES EINFLUSSES VON FAHRZEUGPARAMETERN AUF DAS INSTATIONAERE FAHRRERHALTEN VON KRAFTFAHRZEUGEN

The study is concerned with research into the influence of vehicle parameters on vehicle operation. The influence of basic motor vehicle design on in-motion performance was examined, with particular reference to the distribution of mass. A mathematical model was developed which allowed for 18 degrees of freedom and all couplings, suspensions and shock absorbers as non-linear functions. The results calculated from a series of simulated test drives indicate the favourable influence of high front axle weight, low moment of inertia and long wheel base on the in-motion performance of a motor vehicle during the execution by its driver of rapid changes in course. Furthermore it was evident that by using steering effects which change the performance of the stationary vehicle towards an increased under-steering tendency, the response of the vehicle to steering movements is influenced favourably whereas the damping behaviour is impaired. The dynamics of the vehicle response to sudden changes in the steering angle were discussed on the basis of a linear vehicle model with 2 degrees of freedom. /TRRL/
