| 摘 要： | 为了研究基于动量定理的汽车碰撞模型的同一性,分析了2种典型模型建模坐标系的差别.应用理论和实车碰撞试验相结合的方法,对2种模型的同一性进行了研究.在上述研究的基础上,应用2种模型对同一起汽车碰撞事故进行了分析,结果表明：合理选择力学参数能够保证2种模型计算结果相同,从而研究验证了以质心为坐标原点和以碰撞点为坐标原点建立的汽车碰撞模型的同一性,可为应用同类模型得到的汽车碰撞事故分析结果的相互验证提供依据.

| Abstract: | In order to research the identity of vehicle collision models based on the momentum theorem,the difference of modeling coordinate systems of two typical models was analyzed.The identity of two models was researched by means of the theory and the vehicle collision test.Based on the above research,a vehicle collision accident was analyzed by using two models.The results show that reasonable selection of mechanical parameters can ensure computational results of two models same,thus one model with centroid coordinates origin and another model with collision center coordinates origin are consistency.Research results can provide a basis for the mutual inspection of vehicle collision accident analysis of similar models. |
