초록

철도선형에서 평면원곡선과 종곡선의 경합은 예기치 않은 주위 환경조건들에 의해 빈번히 발생하고 있으며, 이는 차량의 주행안정성, 승차감, 그리고 궤도유지보수비에 많은 영향을 끼친다. 본 연구에서는 경합부의 역학적 이론을 바탕으로 산정된 보정캔트량을 고속철도에 적용하여 궤도에 미치는 영향 및 차량의 주행안전성, 승차감을 분석하여 보정캔트의 효과에 대한 해석적 연구를 수행하였다. 그 결과 보정캔트가 있는 경우가 차량의 주행안전성 및 궤도작용력, 승차감 측면에서 모두 좋은 것으로 나타났다.

Superimposition of horizontal and vertical curves occurs frequently owing to geographical conditions. It may hamper train ride comfort and running safety and inflate maintenance costs. In this study, when the horizontal and vertical curves are superimposed, in order to analyze the effects of the compensation cant, the analytical study for running safety, ride comfort and track forces was performed in high speed line. From the analysis results, it was found that it is better to apply the compensation cant at superimposition part.
