This paper describes motion analysis of vehicles damaged due to collision. Various parts of vehicles are damaged in collisions in general. In this paper, the damages to body and wheels are picked up. The center of gravity of the vehicle and the polar moment of inertia are changed by deformation of the body. Furthermore, the wheelbase, treads and wheel steering angles are changed by the damage to the wheels. Thus the vehicle loses symmetry with respect to the vehicle axis. In this paper, the motion analysis for the vehicle is carried out by extending the four-wheel vehicle model to examine the influence of vehicle damages due to collision on the vehicle motions after impact. Then, the motions of damaged vehicles are compared with those of undamaged vehicles. It was found that damage to vehicles has a significant influence on vehicle motion after impact.
