摘要
为研究厢式客车与行人碰撞后行人运动形态及其损伤机制,根据国家车辆事故深度调查体系(NAIS)中的一个真实案例,利用Madymo仿真软件,建立厢式客车的前部结构模型和中国50百分位的假人模型。在此基础上进行计算机模拟试验,以人体损伤指标为评价标准,研究不同车速和行人朝向对碰撞后的行人运动形态及损伤的影响。结果表明:车速和行人朝向是影响行人损伤程度的主要因素,行人朝向对碰撞后的行人运动形态影响较大;此外,行人先与厢式客车碰撞一侧的小腿损伤值明显大于后碰一侧,行人与地面二次碰撞造成的头部损伤是导致行人死亡的主要原因。
The paper was aimed at studying the movement form and injury mechanism of pedestrian in van-pedestrian collision. Based on a real case provided by National Automobile Accident in-depth Investigation System（ NAIS）,a front structure model of the van and a 50 thpercentile Chinese dummy were built by using the Madymo. Then on this basis,computer simulation tests were carried out with the human body injury criteria as the evaluation standard of simulation experiment,to study the influence of different values of speed and pedestrian facing angle on the movement form and injuries of pedestrian after the collision.The results show that the collision speed of the van and the pedestrian facing angle have a main effect on the pedestrians＇ injuries,that the pedestrian facing angle has a significant effect on the movement form after the collision,that the leg injury values of the first-touch side are significantly greater than those of later one in van-pedestrian collisions,and that the head injuries of pedestrian in the collision with the ground are the main cause of death.
