Abstract

When a railway vehicle passes through curves & transitions, the running speed must be improved by setting limits on the maximum running speed in each section of the conventional line(Dongdaegoo-Namsunghyun) considering derailment safety. Our goal is to improve the maximum running speed of railway vehicle that passes through curves & transitions where there is a high risk of derailment. We examined the influence on the derailment safety when the railway vehicle passes through curves of actual track conditions (Dongdaegoo-Namsunghyun up and down lines). We performed the derailment safety analysis by increasing the running speed on curve radius by 5%.20% compared to existing speed under actual track conditions.

기존선 속도향상 시에 탈선안전도를 고려한 기존선 구간 (동대구-남성현) 최대 운행가능속도에 대한 기준을 제시하여 기존선의 곡선부 및 완화곡선부 통과 시 속도를 향상시키고자 한다. 본 연구에서는 탈선의 위험도가 높은 곡선부 통과하는 열차의 고속향상을 도모하기 위하여 실제 선로조건인 동대구-남성현 상 하행 구간에서의 곡선부 구간별 통과 시 탈선안전도에 미치는 영향을 살펴보았다. 곡선반경별 주행속도를 실제 선로 조건에서의 기존 속도 대비 5-20% 향상시켜 탈선안전도 해석을 수행하였다.
