摘要
为了更好的解决汽车-摩托车碰撞事故的仿真再现问题,一种新的仿真模型及方法被提出。该方法采用Facet模型建立事故汽车及摩托车的三维模型,采用组合式假人模型建立骑车人的三维模型。由Photomodeler软件得出碰撞初始条件,并利用Madymo软件对事故碰撞过程进行直观的三维仿真再现。针对一起实际的轿车与摩托车碰撞事故,采用上述仿真模型及方法进行事故模拟。仿真结果与实际事故情况可以较好吻合,人体损伤数据与法医鉴定结果可以较好吻合,从而验证了此种仿真模型及方法的可行性及有效性。
A new modeling method was proposed in order to analyse vehicle-motor collision accidents. A 3 D model for the accident vehicle and motor was established by the Facet model,and that of the motor rider was established with hybrid FE-MB models. The initial collision conditions were obtained by using the software Photomodeler,and Madymo software was used to reconstruct and simulate the process of collision accident. Based on a practical vehicle-motor collision accident,the modeling method was adopted in the simulation analysis to perform the accident reconstruction. In this way,the simulation results are in good agreement with the actual situation,and the injury conditions of human body also agree well with the forensic identification. Therefore,the modeling method was validated and would achieve good efficiency and accuracy in vehicle-motor accident analysis.
