摘要
小半径曲线钢轨侧磨,历来是城市轨道交通及国铁线路重点关注的问题之一。城市轨道交通线路由于受城市规划及线路周边的条件制约较大,小半径曲线数量多,曲线半径小。延长更换曲线磨耗钢轨的周期,减少养护维修的工作量,降低运营成本,防治小半径曲线钢轨侧面磨耗,已成为工务部门线路维护工作中的重要课题。
Small radius curve rail side grinding,has always been one of the key issues of urban rail transit and national railway line. Urban rail transit routes due to urban planning and the surrounding conditions of the larger constraints,the number of small radius curve,the radius of the curve is small. To extend the replacement curve wear rail cycle,reduce the maintenance of the maintenance workload,reduce operating costs,prevention and control of small radius curve side of the rail wear,has become the work department line maintenance work in an important issue.
