| Abstract: | The application of the finite element method, which is widely used in crashworthiness evaluation and structure optimum design, is limited in the field of traffic accident reconstruction for the restriction of calculating ability. The information of elastic plastic deformations of a vehicle and its crash object produced during the course of a traffic accident can be fully collected by the finite element method, which will greatly increase the computing precision. As the growing of high performance computing technique, the finite element method based on parallel algorithm will play an important roll in accident reconstruction. The direction and movement velocity of pre impact can be exactly obtained, which will provide a scientific foundation for accident judgement. |
