✦ Synopsis

Previous studies of safety during vehicle collision pay attention to phenomena in the short time from starting collision, and the behaviour of rollover is studied separately from that at collision. Most simulation of traffic accidents are two-dimensional. Therefore, it is indispensable for vehicle design to analyze three-dimensional and continuous behaviour from crash till stopping. Accordingly, in this study, three-dimensional behaviour of two vehicles at collision is simulated by computer using dynamic models. Here, by comparison of the calculated results with real vehicles' collision test data, it is confirmed that the dynamic model of this study is reliable. It was confirmed in this study that the dynamic model thus established was applicable to various types of collisions and vehicles.
