대용량 열차충돌 시뮬레이션을 위한 슈퍼컴퓨터의 활용

초록

The purpose of this paper is to simplify the prior analysis procedures of a train crash and to analyze whole and detailed crash behavior. For this study, the FE(Finite Element) model of KHST was used. The full train FE model consists of 1D beam and 3D shell elements and this paper have some figures of the meshed train model. A scenario is to collide one train with another train ate the relative velocity of 30kph. The crash behavior is evaluated by using commercial software, LS-DYNA installed at KISTI's Supercomputing Center. The results show that it is possible to simulate the hybrid FE model of a full train and to improve the model for getting an analysis time to aim.
