COMPUTER SIMULATION OF THE DYNAMIC BEHAVIOUR OF ROAD VEHICLES

In this paper is presented a method of modelization of vehicle suspensions considered as plane mechanisms. The kinematic and dynamic analysis is done with a method previously developed by the authors, that uses basic coordinates as lagrangian coordinates. To modelize realistically the vehicle suspension, a wheel-road subsystem has been incorporated into the program. The wheel is modelized with two basic points in the extremes of a radius, and the road is represented by several spans defined locally with cubic splines and allowing slope discontinuity between them. In this method, rolling and sliding conditions, impact and loss of contact events, and Coulomb friction can be considered. A set of tests that ascertains the true conditions at the contact point is described. Finally an examples solved by this method is presented.
