为更好地了解行人与不同车型车碰撞事故中头部损伤来源,选取轿车、运动型多功能车(SUV)及客车3种典型车型,以车速为变量设计仿真试验。首先借助一个真实案例验证Pc-Crash软件,然后利用该软件开展仿真试验,并用已有模型验证轿车事故中的行人抛距值,最后通过做图分析可知:3种车型事故中行人头部损伤程度均随车速的提升而加重;在相同车速下,SUV事故中行人头部损伤最严重;不同车型事故中,车辆所致损伤最高的是SUV型车,而地面所致损伤最高的是客车;轿车与SUV事故中行人头部损伤主要来源于车辆撞击,而客车事故中行人头部损伤来源较为复杂,但多数情况下来源于地面撞击。
In order to better understand the sources of head injuries in the collision between pedestrians and different models, three typical models of passenger cars, sport utility vehicles (SUVs) and passenger cars were selected to simulate the vehicle speed variation. First of all, a real case is used to verify the Pc-Crash software. Then, the software is used to carry out the simulation test and the pedestrian throw-away value in the car accident is verified by the existing model. Finally, the graph analysis shows that the degree of pedestrian head injury in the three types of vehicle accidents All increased with the increase of vehicle speed. In the same speed, the head injury was the most serious in SUV accidents. In different vehicle accidents, SUVs were the most damaged, In the accident with SUV, the head injury of pedestrians mainly comes from the collision of vehicles, but the source of pedestrian head injury in passenger car accidents is more complicated, but in most cases it comes from ground impact.
