완성열차의 충돌안전도평가를 위한 가상시험모델의 개발방법연구

초록

A complete train set should be validated in the view of crashworthiness before operation for passengers. most europe countries doesn't test a complete train set for crashworthiness performance in real site because of cost. In stead of test, they use 3-D numerical analysis model for simulation. In this paper, we studied the method of developing the model. In other words, we found the factors affecting highly crashworthiness performance and studied how reflecting the factor in the model. Also, wheel-rail modeling method was studied because wheel-rail interaction can induce train derailment.
