Abstract

Since PSDs(Platform Screen Doors) are set up at many subway stations, their design related to safety has become gradually important. In particular, the interference check with a running railway vehicle is the most important of performance indices because the collision between PSDs and vehicles can be dangerous for passengers in the car and on platforms. When the train comes into a station with a curvature, the passenger car has a large translational and rotational motion and the displacement is enough for coming in contact with PSD. The performance is affected by many design parameters such as rail design parameters and vehicle velocity. This study proposes dynamic analysis models for railway vehicles and rails. Some parameters were also considered in the models to determine their influence on the performance.

기 현재 많은 역사 내에 PSD(Platform Screen Door)가 설치되어 있고, 이러한 PSD의 안전성이 중요시 되고 있다. 특히 운행중인 도시철도차량과의 간섭은 가장 중요한 부분으로 PSD와 차량의 충돌은 차량 및 승강장에 위치한 승객의 안전을 위협하기 때문이다. 곡선구간에 위치한 승강장을 차량이 진입할 때에 차량의 병진운동과 회전운동을 하기 때문에 PSD와 충분한 간격을 가지고 있어야 한다. 차량의 병진운동과 회전운동은 레일상태, 차량한계, 차량속도 등에 의해 영향을 받는다. 본 연구에서는 도시철도차량, 레일, 기타 매개변수들과 같이 차량의 움직임에 영향을 미치는 요소들을 고려한 도시철도차량의 동적 해석방법을 제시하고자 한다.
