Abstract

With speed up of railway, the demand for safety of the railroad transportation is on the increase in Korea's conventional railways. In additions, freight trains with heavier axle load are required to run conventional railways. In order to solve these requirements, the increase of rail weight and the application of long rail system have been underway in conventional railways. However, the research on ties that is absolutely influencing the track stiffness in ballasted tracks has not been much progress. In this paper, the new H-typed tie is developed to increase the track stiffness and reduce the track irregularity. And from the structural analysis by FE program, the intial design drawing of the new H-typed tie is proposed.

고속화가 이루어지면서 철도수송의 안전성에 대한 요구가 한국의 기존선에도 더욱 증가하고 있다. 또한 더욱 무거운 축중을 가진 화물열차의 주행이 기존선에 요구되고 있다. 이와 같은 요구를 해결하기 위하여 레일의 중량화와 장대화가 기존선에서 진행되어 왔다. 그러나 자갈도상궤도에서 궤도강성에 절대적으로 영향을 미치는 자갈도상용 철도침목에 관한 연구는 큰 진전이 없었다. 본 연구에서는 궤도강성을 증대시키고, 궤도틀림을 저감시킬 수 있도록 새로운 H형 침목을 개발하였다. 또한 FE 프로그램을 이용한 구조해석을 통해 새로운 H형 침목의 설계도를 제안한다.
