机车作用下曲线钢轨垂直力和横向力的测试

The Test of the Vertical Force and Horizontal Force of Curved Rail Under the Locomotive

本文根据长沙铁路分局管内京广线1990年换铺60 kg/m钢轨后现场测试机车作用下曲线钢轨垂直力与横向力的试验数据,分析曲线钢轨受力状况及其与钢轨侧磨的关系,从而得到曲线钢轨受力统计最大值及合理超高.

Based on the test data of the vertical force and horizontal force of curved rail under the locomotive, which are obtaind after the Bei-jing-Guangzhou Railway was re-laid with the rail of 60kg/m wi-thin the jurisdiction of the Changsha Branch of the Guangzhou Railway Bureau in 1990, this paper analyses the stress state of the curved rail and the relation between it and the lateral abrasion of the rail sothat the greatest statistical stress value and the reason-able overheight are found.
