Review on the Modification of Carbody Structure to meet the Collision Condition Applied for Railway Vehicles

철도차량의 충돌 조건 만족을 위한 차체 프레임 개선 사례에 대한 고찰

Currently in design and manufacturing of railway train overseas markets, criteria for a collision condition between vehicles is noted in design specification. In the event of a train crash, it can be verified by crashworthiness analysis or an actual crash test for car's performance to keep the safety of passengers and to minimize the effect of damaged for vehicles. In this paper, it is described for carbody structure to meet the allowable condition in collision analysis through improvement of shape, position and arrangement for carbody frame. This report describes the shape of end frame for carbody structure and the results of analysis applied to actual cases for overseas.
