Nowadays, with the demand for ride quality, the vibration characteristics of vehicle is a high priority in car design. The vibration characteristics of full vehicle is related to ride property and affected by each vehicle components property, i.e. stiffness or damping of suspension, power train, car body and its mounts. In this paper, to get operating deflection shape of full vehicle, the analytical vehicle model based on multi-body dynamics was used. For the purpose, the whole vehicle parameters used in multi-body dynamics analysis were measured from experimental results. From computational method, the operating deflection shape of full vehicle to random base excitation were analyzed.
