인장 변형을 이용한 장애물제거기의 해석적 연구

초록

While many domestic studies have been focused on railway safety matters, there are only few studies focused on Obstacle Deflector which is installed at the front side of railway cars to remove dead animal bodies, trees, or other small obstacles. A new tension-based obstacle deflector suggested in this study is aimed at supplementing the weaknesses of previous removal devices such as unstable load application and uneven energy absorption which are mainly caused by the compression and bending-based system. For the new obstacle deflector , the Finite Element Model is composed through Hypermesh and numerical analysis through LS-DYNA.
