基于轮轨动态力测试的小半径曲线车辆运行安全性分析

The Operation Safety Analysis of Vehicles on Sharp-radius Curve Based on the Test of Dynamic Wheel-rail Forces

结合嘉镜铁路列车提吨试验,选取小半径曲线的曲中点作为轮轨动态力的测试断面,对提吨重车和普通重车的测试数据进行对比分析,利用车辆运行安全性评价指标来确定列车提吨是否可行以及对该曲线地段的日常养护维修提出合理建议.

With the test of increasing the traction tonnage of train on Jia-jing Railway,the mind point of sharpradius curve is chosen as testing section of dynamic wheel-rail forces. This article gives some comparative analysis of the testing data between the loaded train which increased the traction tonnage and normal one. Using the index of the Operation Safety of Vehicles to determine the feasibility of increasing the traction tonnage of train,some rationalization proposals in daily maintenance about this curve section are put forward.
