충돌안전성능 향상을 위한 일반철도 전두부의 개념모델 개발에 관한 연구

초록

The purpose of this paper is to develop crshworthiness structural design of next generation of Korean Railway Vehicle. To this purpose, Two main design concepts are setup to protect the both crews and passengers from serious injury at heavy collision accidents, and to reduce damages of the train itself at light collision accidents. In order to improve safety, the front end structure can absorb an amount of impulse energy with controlled manner. After many failures, the proposed design could be produced. In the process of the conceptual design, a multi-step energy absorption strategy was proposed. The adequate design on each structural part such as energy absorption tube, headstock, and aluminum honeycomb was carried out to find out the controlled crush characteristics.
