摘　　要：为研究某车型行人保护性能,用LS-dyna软件进行了小腿冲击保险杠的碰撞试验,分析了造成行人损伤的相关因素,研究了保险杠参数对行人保护性能的影响,并通过优化保险杠参数提升了该车型的行人保护性能。研究表明,正交试验及主效应分析法对解决此类问题是有效的。In order to analyze the function of pedestrian protection of one vehicle,an impact test in which shank was used to impact the bumper was carried out via Ls-dyna software.The test analyzes the relevant elements that causes the pedestrian damage and the influence of bumper parameter on pedestrian protection function, and promotes the vehicle＆#39;s pedestrian protection function by means of optimizing the bumper parameters. The test indicates that the orthogonal test and main-effect analytical method are valid solutions to solve this type of problems.
