완충장치를 설치한 열차의자의 충돌 시뮬레이션을 통한 성능평가

초록

When train crash accident happened, second impact occur between passengers and interior. The train should protect a passenger from impact by seat itself because there is no safety device like a seat belt and a air bag. So, in this paper present the additional energy absorbing structure in the supporting leg parts in order to improve seat’s energy absorption and passenger’s safety. And we study on the simulation technique on the seat's deformation and evaluation in the train collision accident. To make reliable simulation model, Computational simulation will be implemented and verified by sled test.
