缓解快速线路曲线入口结构性晃车问题的探讨

Exploration on Removing Structural Shaking of Trains Passing Through the Entrance to Curves on Fast Railways

为减小列车由直线进入曲线时车轮对轨道产生的横向冲击力,对曲线入口的结构性晃车问题进行了分析,进而对轮轨游间及相关技术标准进行了讨论,从机车车辆和线路2个方面提出了建议。

In order to reduce the lateral impulsive force on the track by wheels when train runs from a straight line into a curve, the authors analyze the structural shaking of trains at the entrance of curve, then discuss the clearance between wheel flange and gage line, and also discuss the related technical standards. Finally, suggestions are given from the aspects of rolling-stock and lines.
