CAR VERTICAL DYNAMICS 3D SIMULATOR USING A 7 DOF MODEL

Dan N. DUMITRIU

Abstract


This paper presents a 3D car simulator, concerning only the vertical dynamics, described using a 7 DOF car model. This simulator is realized in Matlab/Simulink and will be used for further studies on wheel-road adherence, passenger comfort and the use of appropriate suspension shock absorbers to improve both adherence and comfort. This simulator will also be used to validate a road response simulator, designed as a reconfigurable haptic interface that includes real-time wheel/road dynamic contact simulation in its control system.

Key words: 7DOF car model, vertical dynamics, 3D simulator, Matlab/Simulink, dynamic contact, wheel-road adherence, passenger comfort
