초록

철도선형에서 종곡선과 평면선형의 경합은 차량의 주행안정성 뿐만 아니라 건설비에도 많은 영향을 끼칠 수 있다. 본 연구에서는 종곡선과 평면곡선의 다양한 경합조건별 차량의 주행안전성 및 승차감에 미치는 영향을 분석하였다. 그 결과 종곡선과 평면원곡선의 경합 뿐만 아니라 종곡선의 완화곡선상 경합, 그리고 완화곡선-원곡선 연결부상의 경합에서도 차량의 주행안전, 승차감 및 궤도작용력 기준을 모두 만족하는 것으로 나타남을 알 수 있었다.

In railway construction, superimposition of horizontal and vertical curves has critical effects on the running stability and the ride comfort of vehicles as well as on construction costs. In this study, running safety, ride comfort, and track acting forces were analyzed by a numerical analysis using the VAMPIRE program according to cases of superimposition of vertical and horizontal curves. From the analysis results, it was found that running safety, riding comfort, and track acting forces in the case of superimposition of vertical and horizontal curves as well as vertical and transition curves meet all of the criteria. Also, in the case of the superimposition of vertical curves and curvature change between horizontal transition curves and circular curves meet all of the criteria.
