Abstract

This paper was primary a research of the seat belt protection of train driver during secondary impact of rail crash. The driver injury mainly came from the impact with interior structure of train cab. The finite element model of console, seat belt and driver's seat were detail built to simulate the crash interface of driver and Hybrid III dummy was applied to simulate the train driver. Compared with the train driver without seat belt, the injury index from crash simulation results with two-point seat belt restrained could be more serious in given rail crash scenario because of the different dummy motion and impact interface with the interior structure. It wasn't recommended to use two-point seat belt in train driver passive safety protection.
列车驾驶员在二次碰撞时的安全带保护
本文对铁路碰撞二次冲击时列车驾驶员的安全带防护进行了初步研究。驾驶员的损伤主要来自于对列车驾驶室内部结构的撞击。详细建立了控制台、安全带和驾驶员座椅的有限元模型,模拟驾驶员碰撞界面,采用Hybrid III假人模拟列车驾驶员。与未系安全带的列车驾驶员相比,系两点式安全带的仿真结果表明,由于假人运动和与车厢内部结构的碰撞界面不同,在给定的碰撞场景中,列车驾驶员的伤害指数可能更严重。不建议在列车驾驶员被动安全防护中使用两点安全带。
