PREDICTION OF VEHICLE EVOLUTIONARY RANDOM RESPONSE INDUCED BY ROAD

Abstract

Abstract: The vertical model of vehicle dynamics and the virtual model of road input are deduced. Based on the finer integration method in time domain and the virtual excitation method, a simple and convenient algorithm is suggested for obtaining the road induced evolutionary random response of a time-invariable vehicle system. As an illustrative example, the road induced random response of a quarter-car model is explored. The results verified that the present algorithm is effective.

Key words: Finer integration method, Random vibration, Vehicle response induced by road, Virtual excitation method
