Vehicle Ride Comfort Simulation under Pulse Road Surface Based on Multi-Body Dynamics

Abstract

The shock absorber model and front beam model of a domestic car are built using UG according to the existing two-dimensional drawings. And they are assembled together with the rear beam model, steering knuckles model and arm model. The ADAMS software is used to build up an assembled vehicle model, which includes front and rear suspensions, chassis, steering, tires subsystems and so on. Response characteristics of vehicle ride comfort under pulse road surface are studied through simulation.
