Abstract

In this paper, we propose a collision simulation technique the evaluation of urban trains. We perform simulation that include a dynamics bogie model which represents the dynamic behavior of bogies and a finite-element model that can model crash behavior. We perform simulation in accordance with the 40-mm vertical offset head-on scenario for overriding the evaluation of the EU and domestic crashworthiness regulations. We evaluate the overriding by the vertical displacement of the wheelset using the overriding evaluation standard. Finally, if proposed simulation technique is applied, we can evaluate the overriding for urban-train crashworthiness regulations.

본 논문에서는 도시철도차량의 타고오름 평가를 위한 충돌시뮬레이션 기법을 제안하였다. 시뮬레이션모델은 대차의 동적 거동을 표현하는 대차 동역학 모델과 붕괴거동을 표현할 수 있는 차체 유한요소 모델로 구성된다. 유럽 및 국내 충돌안전규정의 타고오름 평가를 위해 40 mm 오프셋 정면충돌 사고 각본에 따른 시뮬레이션을 수행하여 충돌 후 차체의 구조적 거동과 차체와 연계된 대차 모델의 동적 거등을 확인하였으며 타고오름 판단기준인 윤축의 상승거리로 타고오름을 평가하였다. 최종적으로 본 연구에서 제안한 시뮬레이션 기법을 적용하면 도시철도차량 충돌안전규정에 따라 충돌사고 시 타고오름에 대하여 평가할 수 있음을 확인하였다.
