Abstract

Heights of a platform above the rail for the passenger train in the country are classified into two categories such as the low level (500mm; mainline) and the high level (1,135mm; metropolitan subway line) platforms. In order to operate similarly both a mainline railroad and a metropolitan subway line, as the requisite door safety system, it is necessary to develop the doorstep equipment of the rolling stock regardless of both the low and high level platforms. In this study, Structural analysis and mechanical strength test of doorstep equipments used for two types of platforms are performed on the supposition that the train only for the low level platform could stop in the both low and high level platforms.

국내 여객열차 전용 승강장은 높이에 따라 두 가지 종류로서, 일반 간선열차에서 주로 사용하는 저상 승강장과 수도권 전동차에서 주로 사용하는 고상승강장으로 구분된다. 중 고속 열차가 수도권 전철구간과 본 선구간에서 혼용할 경우에 안전운전 및 승객편의를 함께 고려하기 위해서는 저상/고상 승강장에 상관없이 승하차할 수 있는 승강문 스텝장치가 필요하다. 본 연구에서는 전철역사 및 일반 철도역사에서 모두 승하차가 가능한 저상/고상 승강장 겸용 승강문 스텝 개념설계(안)의 구조해석 및 강도시험을 수행하고 이의 안전성을 검토하였다.
