Abstract
일반 간선열차에서 주로 사용하는 저상승강장과 수도권 전동차에서 주로 사용하는 고상승강장을 동시에 안전운행하기 위한 니즈기술로서, 저상/고상 승강장에 상관없이 승하차할 수 있는 철도차량 승강문 스텝장치가 필요하다. 본 연구에서는 이를 대비하여 저상/고상 승강장 겸용 승강문 스탭의 기능 및 제작 요구사항을 검토하였다. 세밀히 검토한 결과, 합리적 설계안은 자체 언더프레임의 손상 및 철도승강장의 이격거리 변동성을 최소화 할 수 있는 텔레스코픽 슬라이딩 스텝방식이라고 판단된다. 또한 다양한 요구조건을 고려하여 각 단계별 스텝 동작 과정 및 제어 흐름도를 제시하였다. In order to operate trains both mainline railroad platform and metropolitan subway line platform, it is necessary to develop the doorstep equipment of the rolling stock regardless of low(500mm, mainline) and high level platforms(1,135mm, metropolitan subway line) because of the requisite door safety system. In this study, two different types of platforms were examined. On closer examination, it seems that the conceptual design is suitable for telescopic sliding type doorstep equipment to minimize damage to the carbody underframe of railway vehicles and can also minimize the variation of the distance between the railway platform. Furthermore, the operation process and control flowchart of doorstep equipments by stages are proposed by various performance requirements.
