초록

본 연구에서는 서울메트로 2 호선 상왕십리역에서 발생한 전동열차 충돌사고에 대하여 사고재현 시뮬레이션을 수행하고 사고 발생 시 피해를 최소화할 수 있는 개선방안을 제시한다. 사고재현을 위해 상용 충돌해석 소프트웨어인 LS-DYNA를 사용하여 1 차원 및 3 차원 시뮬레이션을 수행하였다. 1 차원 시뮬레이션을 통해 각 차량 연결기의 하중, 변위, 충격흡수 에너지 및 차량의 가속도를 분석하여 사고 시 충돌안전도를 평가하였으며, 3 차원 시뮬레이션을 통해 차량의 변형 및 타고오름 현상을 분석하였다. 또한 사고 전동차의 충돌안전도 향상을 위한 개선방안들을 제시하고, 그 중 선두차량에 고용량 완충장치를 적용하는 방안에 대하여 1 차원 시뮬레이션을 통해 충돌안전도의 개선 여부를 확인하였다.

In this study, we simulate the railway crash accident that occurred at the Sangwangsimni station on the Seoul Metro Line #2, and we propose a solution to minimize the damage. We use LS-DYNA, which is the commercial software employed for collision analysis to perform 1-D and 3-D simulations for the recurrence of accidents. By performing 1-D simulations, we analyze the load, displacement, absorbed energy of the couplers, and acceleration of vehicles, and we evaluate the safety in accidental collisions. By performing 3-D simulations, we analyze the deformation of the car and over-ridding. We propose methods to improve the safety in collisions involving railway vehicles, and we perform collision accident simulations to determine improvements when applying a high-performance energy absorber to the front car.
