도시철도 곡선궤도의 완화곡선과 레일 편마모 상관관계 연구

초록

The purpose of this study is to investigate the mutual relations between transition curve and side wear for curved track. For this, we have done a comparative analysis for curves that nearly reach limitation of the rail wear patterns at the beginning point of curve and the rail wear fluctuation in the section of circular curve . As a result, we found that curves which don’t have transition curve steep incline pattern of rail wear at the beginning point of curve and high coefficient of variation in the circular curve.
