中文摘要：

目的将计算机仿真技术应用于道路交通事故鉴定领域，实现道路交通事故发生过程及当事人致伤方式的重建。方法基于对事故现场痕迹、车辆损坏和人体损伤等检验鉴定，利用事故再现软件及高性能计算机计算分析，对40起真实事故的碰撞过程及致伤方式进行重建分析，并以2起典型案例进行说明。结果事故再现效果与现场痕迹、车辆痕迹、人体损伤痕迹有关；40起事故再现中．28起符合性好，9起较好，3起欠理想；碰撞过程的准确再现有助于对致伤方式进行分析。结论计算机仿真模拟重建道路交通事故的发生过程及当事人的致伤方式在辅助道路交通事故鉴定中具有应用价值。

英文摘要：

Objective To reconstruct the collision process of traffic accident and the injury mode of the victim by computer simulation technology in forensic assessment of traffic accident. Methods Forty actual accidents were reconstructed by stimulation software and high performance computer based on analysis of the trace evidences at the scene, damage of the vehicles and injury of the victims, with 2 cases discussed in details. Results The reconstruction correlated very well in 28 eases, well in 9 cases, and suboptimal in 3 cases with the above parameters. Accurate reconstruction of the accident would be helpful for assessment of the injury mechanism of the victims. Conclusion Reconstruction of the collision process of traffic accident and the injury mechanism of the victim by computer simulation is useful in traffic accident assessment.
