摘要
建立了汽车与行人碰撞的系统仿真模型。通过改变汽车前部结构参数,分析其改变对行人膝关节损伤的影响,从而得出各结构参数使行人膝关节损伤较小的优区间,并在其基础上进行优化组合分析,提出了对行人膝关节损伤较小的汽车前部结构。通过与事故统计分析结果的对比,验证了研究结果的正确性。
A vehicle-pedestrian impact simulation model is built. By changing the front-end structure parameters of the vehicle, their effects on knee injury of pedestrian are analyzed. Thus the superior intervals of the structure parameters that cause less injury to the knee of pedestrian are obtained. A combination analysis is conducted on these superior intervals for different structure parameters, and hence a front-end structure of vehicle, which causes minor injuries to pedestrian knee, is singled out. The comparative analysis with traffic accident statistics verifies the conclusion of the study.
