汽车行人碰撞抛射仿真模型

利用PC-Crash软件进行车辆与行人的碰撞仿真试验,提出了第一落地点抛距理论模型,将车辆与行人的碰撞划分为车辆前部与行人的后部和侧面碰撞两种类型,碰撞车型选择当前广泛使用的发动机舱盖略向前下倾斜的梯形前端轿车,建立了车辆与行人后部、侧面碰撞抛距模型和综合碰撞抛距模型,分析了行人相对车辆前端的不同位置对抛距的影响。最后将文中提出的模型与国外行人抛距模型进行对比,结果证明该模型是有效的。

Throw Distance Model for Vehicle/Pedestrian Collisions

A simulation experiment on vehicle-pedestrian collisions is conducted by using PC-Crash software and the first throw distance model is presented.Choosing the most popular car with sloped bonnet as the object,both the first and final throw distance models are obtained for 3 types of collisions respectively with the back,side and uncertain part of pedestrian against the front end of the car.Meanwhile the effect of pedestrian's position relative to the car on throw distance is also analyzed.Finally the presented throw distance model is compared with that proposed by foreign scholars in literature,showing that they are basically close to each other.
