摘要
基于多刚体动力学软件PC-Crash,对一起实际发生的轿车与行人碰撞事故进行重建,分析碰撞后行人的运动学响应过程及损伤部位的动力学响应参数,将仿真中得到的行人运动学响应及损伤部位的动力学响应结果与法医尸体检验报告中的客观事实进行对比,验证PC-Crash重建模型的可靠性,得到了仿真结果与客观事实相吻合的结论.结果表明,利用PC-Crash软件对实际案例快速重建,对于研究交通事故中行人损伤机理和鉴定事故责任具有重要的参考价值.
Based on multi-rigid-body dynamics software PC-Crash, an actual accident was reconstructed, the kinematics response process and the dynamics response parameters of injured parts of the pedestrian in the accident were analyzed. Comparing the simulation results of kinematics and dynamics response of the injured parts of the pedestrian with the facts of forensic autopsy＇s report,the reliability of PC-Crash reconstruction model was verified, the conclusion of the simulation result was consistent with the objective facts. The result shows that PC-Crash software can quickly reconstruct car-pedestrian collision accident, which can provide an important reference value for study on pedestrian injury mechanism and identification of accident responsibility.
