도시철도 열차운행속도와 레일마모 상관관계 분석

초록

On the curved track of urban railway, appropriate cant according to curve radius and design speed should be considered in order to improve ride quality and prevent train derailment. But, the actual cant installed in the field is different from the balanced cant by reason of scheduled speed improvement, ride quality improvement at the reversed curve, noise reduction and speed down by ATO. In this study, to find out the impact of cant excess or deficiency which would be varied by the train running speed on rail wear, the correlation between the progress of rail wear and the amount of cant excess or deficiency was analyzed.
