| 摘 要： | 在轿车-行人碰撞事故中,影响行人头部损伤的车辆前部结构参数主要有:保险杠中心离地高度、保险杠宽度和伸出长度、发动机盖前缘高度及发动机盖倾斜角等.文中首先建立了儿童行人的仿真模型,并利用事故重建验证了仿真模型的可靠性;接着采用正交试验分析了上述参数对儿童头部伤害指数的影响;最后将所得结果和成年行人头部损伤的相关指数进行比较.结果表明,前部结构参数对儿童头部损伤的影响比成人的大,其中发动机盖前缘高度对儿童行人头部伤害的影响最为显著.

| Abstract: | In car-pedestrian crash accidents,the main parameters of car front-end structure that influence the head injuries of child-pedestrian are the height,width and protruding length of bumper and the front-edge height and slope angle of hood.In this paper,a simulation model for a child-pedestrian is built with its reliability verified by accident reconstruction.Then an orthogonal test is conducted to analyze the influence of the above-mentioned parameters on the head injury indices of child-pedestrians.Finally t... |
