为研究行人与车辆碰撞后的抛距、运动姿态及其损伤机制,根据国家车辆事故深度调查体系(NAIS)中的2起真实案例,针对事故中常见的厢式客车和普通轿车车型,基于MADYMO多刚体仿真软件,建立符合中国人体形特征的人车碰撞多刚体模型。在此基础上进行计算机模拟试验,研究2种车型不同车速和碰撞角度对碰撞后行人动力学响应及损伤的影响。结果表明,车型和车速是影响行人抛距和损伤程度的主要因素,而碰撞角度对行人碰撞后的运动姿态有较大影响。
In order to study the throw distance, the movement attitude and the damage mechanism after the collision between pedestrians and vehicles, according to two real cases in the national vehicle accident depth investigation system (NAIS), according to the common van and common car models in accidents, Multi-rigid body simulation software to build a human-body collision multi-body model that conforms to Chinese body shape characteristics. On this basis, the computer simulation test was carried out to study the influence of different vehicle speeds and collision angles on the pedestrian dynamic response and damage after the collision. The results show that the vehicle type and vehicle speed are the main factors affecting the pedestrian throw distance and the degree of damage, while the collision angle has a greater impact on the pedestrian attitude after the collision.
