地道桥上列车脱轨系数试验研究

Test Research on Derailment Coefficient of Train on Underpass Bridge

运用试验的方法对列车通过地道桥时的脱轨系数进行了研究 .根据实测的列车过桥时的轨道力 ,分别分析了客车与货车过桥时脱轨系数的变化规律 ,并统计出脱轨系数与车速关系的经验式 。

In this paper,the derailment coefficient of train on underpass bridge is studied by testing.According to the track force tested when the train passes bridge,the rule of derailment coefficient on passenger train and lorry is analyzed respectively.And the experiential formulae for the relationship between derailment coefficient and train speed is gained by statistics.On the basis of the formulae,the derailment coefficient of speed advanced train is estimated.
