Abstract

The platform of railroad station for domestic passenger train has been operated at two categories like the platforms if low level(500mm, mainline) and high level(1,135mm, metropolitan subway line). To operate both metropolitan subway line and mainline railroad safely, it is essential to develop the doorstep equipment of railway vehicle regardless of low and high level platforms. On the other hand, the domestic test standard at durability and reliability of doorstep equipment has not been existed until now. This study aims at the development on doorstep equipment of telescopic sliding type for low and high level platforms. Durability analysis with VPD(Virtual Product Development) techniques are performed and the durability standard & qualification life through the rig test during no failure test time is examined in accordance with reliability qualification test.

국내 여객을 취급하는 철도역사의 승강장은 간선철도노선의 저상승강장(500mm)과 광역전철구간의 고상승강장(1135mm)으로 구분 운용되고 있다. 저상승강장 전용 중 고속 열차가 수도권 전철구간(고상승강장)과 본선구간(저상승강장)에서 혼용 운영될 경우를 대비하고 안전운전 및 승객편의를 함께 고려하기 위해 저상 고상 승강장 겸용 승강시스템의 개발은 필수적이다. 한편 현재 개발 중인 시스템(스텝)에 대한 국내의 내구성 및 신뢰성 시험 기준은 존재하지 않는다. 따라서 본 연구에서는 저상/고상 승강장 겸용 텔레스코픽 슬라이드방식 승강문 스텝의 개발을 위한 연구 일환으로서, VPD관점에서 내구성 해석을 수행하고 신뢰성 보증시험에 준한 무고장 시험시간동안 실물 리그시험을 통하여 이의 내구성 기준 및 보증수명을 검토하였다.
