Abstract

When a vehicle passes through a turnout, it is necessary for the changes in lateral force to be minimized to ensure the safe running of the vehicle. Therefore, the analysis of the interaction between the vehicle and the turnout is crucial for estimating the lateral force and the derailment coefficient on the turnout. In this paper, the effect of the variation of section shape on the running safety of a vehicle was investigated by changing the shape of the point part and the crossing part. The tongue rail length of the point part and nose rail height of the crossing part of an F10/F12 turnout were changed, and the running safety of the vehicle was analyzed.

현재 철도차량이 분기기 통과 시에 횡압의 변화가 최소화하는 설계가 요구되고 있다. 따라서 차량이 분기기를 통과하는 경우에 분기기에 작용하는 횡압 및 탈선계수를 예측하기 위하여 차량과 분기기간의 상호작용에 따른 동역학 해석을 수행하여야 한다. 본 연구에서는 분기기 단면 형상 변화가 차량의 주행안전성에 미치는 영향을 살펴보기 위해 포인트부, 크로싱부의 단면 형상 변화에 따른 주행안전성 해석을 수행하였다. F10/F12 분기기를 대상으로 포인트부 텅레일의 길이, 크로싱부 노즈레일의 높이를 변경시켜 주행안전성 해석을 수행하였다.
