摩托车与汽车侧面碰撞时摩托车两乘员头部受力分析

Head stress analysis of motorcycle’s two crew members in a car-motorcycle side-crash

针对常见的汽车与摩托车的侧面碰撞事故,为了使结果更加直观化,研究了摩托车上两个乘员头部受力随时间的变化。利用PC-Crash软件,建立虚拟试验场。依据汽车车速、摩托车车速、碰撞部位等进行分组,并且结合同济大学"上海市联合道路交通安全科学研究中心"所采集的两起事故案例,分析了摩托车驾乘者头部受力的峰值以及与随时间轴变化面积区域。结果表明:无论何种碰撞速度下,摩托车驾乘者头部伤害都与轿车碰撞摩托车的部位有关,靠近碰撞点的摩托车驾者或乘者,受到更严重的伤害。

The relationship between the head subjected forces of two motorcycle occupants and time was analyzed to obtain more intuitive results in car-motorcycle side-impact, which is a common accident. Virtual field experiments were made with PC-Crash software to simulate and analyze head subjected forces. The simulations are grouped based on the vehicle velocity, the motorcycle velocity, the collision position, etc. Two accident cases recorded by Shanghai United Road Traffic Safety Scientific Research Center at Tongji University were used as data base. The force peak and the region area changing with timeline were analyzed for different conditions. The results show that the motorcycle occupants＇ head injuries are related to the collision position of the motorcycle at any kind of impact velocity and that the one who is closer to collision point is more vulnerable to injury.
