Dynamic Simulation of a Motor Vehicle in Virtual Prototyping Environment

Abstract

In this paper, we attempt to carry out the dynamic analysis of a motor vehicle, using the virtual prototype developed with the MBS (Multi-Body Systems) software ADAMS. The virtual prototype includes the front and the rear suspension subsystems, the steering subsystem, and the car body subsystem. The experiment designed is one frequently carried by the automotive manufacturers, namely passing over bumps. The connection between wheels (tires) and road (ground) is made using contact forces, which allow modelling how adjacent bodies interact with one another when they collide during the simulation. On the virtual prototype, several measurements have been realized having in view to evaluate the dynamic behaviour of the vehicle.
