3차원 유한요소법을 이용한 일반철도차량의 충돌해석 연구 및 평가

초록

In order to design safety trains, it is important to predict the collision characteristic of train. There are two models to predict the behavior of train at various train accidents. First model is that a Motorized Cap Passenger car is collided against rigid wall at overspeed and composed of Motorized Cap Passenger car with another parts modeled as concentrated mass attached to the end. Second model is that a whole train is collided against rigid wall as TSI scenario and composed of three cars with other parts modeled as concentrated mass coupled by coupler. This study is conducted by using Finite Element Method to estimate the ability of absorbing crush energy.
