摘　　要：以一起典型的大客车碰撞事故为例,综合利用摄影测量方法、变形/能量方法和多刚体动力学方法,建立了车辆和事故现场模型,对车辆碰撞过程、人体损伤和车辆内饰变形进行数值仿真再现,并与痕迹物证及医学鉴定结论进行对比,验证了方法和模型的准确性。Taking a typical accident case of bus crash as example,comprehensively using photogrammetry technique,deformation/energy method and multi-rigid-body dynamics,and setting up the models for vehicle and accident site,a numerical simulation for the reconstruction of vehicle impact process,human body injuries and vehicle interior deformation is performed.The results are compared with trace evidence and medical judgment conclusion,verifying the correctness of the method and models used.
