摘要
通过分析汽车与行人碰撞的特点,建立常见人车碰撞事故的模型,利用PC-C rash软件进行多次模拟仿真,计算出相应的动力学参数及碰撞后行人的运动状态,总结出事故发生后人体头部与车体前部碰撞点的分布规律。最后在发动机罩结构性能的改善以及安全气囊的有效安装位置等方面提出了有效的保护行人的措施。
The character of the pedestrian traffic accident was induced through the statistical analysis, hereby, the familiar typical model of pedestrian traffic accident was built ,then the accidents were simulated by the software of PC-Crash several times. The kinetic parameters and the pedestrian＇ s postures after impaction were calculated, and the head impact location distribution was received. Then bring up some advice on the improvement of the structure of the hood, such as based on the impact location adjusting the structure under the hood,fixing airbags on the accurate position,etc.
