Soil trip-over simulation was carried out based on real world accidents. Based on rigid body dynamics, PC-Crash software was chosen to make an accident reconstruction analysis of some selected cases chosen from an accident database (NASS-CDS). ...With SUVs and minivans accounting for a larger share of the US market in the past decade, rollover accidents have drawn greater attention, leading to more active research from different perspectives. ...This ranges from investigations for elucidating the basic causes and mechanisms of rollover accidents to studies of more advanced occupant protection measures. As the phenomenon of a rollover accident is longer in duration than frontal, side or rear impacts, it is relatively difficult [1] to simulate such accidents for experimental verification and also for proper evaluation of occupant restraint system performance.

Vehicle's dynamic pre-crash state and associated occupant motion may influence the damage and injury of traffic accidents. Therefore it is important to simulate phenomena before and after impact continuously in order to analyze the damage mechanisms of traffic accidents. ...Therefore it is important to simulate phenomena before and after impact continuously in order to analyze the damage mechanisms of traffic accidents. In this study, a finite element vehicle model that can simulate both running and crash is developed and verified by some experimental results, and the methods to speed up and stabilize computation that enable continuous simulation are developed and compared with conventional methods. ...A numerical example that simulates a real traffic accident situation is also shown.

This importance can also be inferred from the fact that almost all of the accidents classified as frontal crashes in real-world driving have an impact angle. The first step of this research was to make clear the differences between inline offset impacts and oblique offset impacts, focusing on the behavior of the vehicle.
