摘　　要：论述了人车碰撞事故再现的仿真方法和发展趋势,强调了研究平头车撞人事故再现的重要性,提出了相应的事故再现方法.该方法应用了有限元-多刚体接触法,能更好地模拟行人与大客车曲面之间的相互作用,以及由此引起的人体损伤.以两起真实大客车事故为例,初步验证了再现平头车与行人碰撞事故的可行性.还结合法医报告考察了行人的损伤情况,指出基于人体损伤进行事故再现所面临的问题.The research methods and key problems of reconstruction of vehicle-pedestrian collision are discussed in this paper. The significance of pedestrian safety of flat front vehicles such as buses and trucks are indicated specially. Also, a simulation method is presented for pedestrian accident involving fiat-front vehicle and applied to two real-world buspedestrian accidents. In this method, the front surface of the bus was approximated by triangular or quadrangular elements using 3D digital photogrammetry, so that the interaction between bus and pedestrian can be described based on finity element-multi body contact algorithm. Furthermore, by comparing autopsy reports with simulation, we find that pedestrian injuries, especially chest injuries, can be used as reconstructive factors in fiat-front vehiclepedestrian accident.
