Seat belt protection of train driver during secondary impact

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.
