单轮对脱轨试验及其理论分析

Experiment and Analysis of the Single Wheelset Derailment

介绍了在滚动振动试验台进行的单轮对脱轨试验的试验系统、试验过程和试验结果，同时利用仿真计算，对单轮对试验进行理论计算，并就单轮对脱轨问题进行探讨，提出轮载荷减载率是引起脱轨的主要原因。

According to the derailment experiment with a single wheelset on railway vehicle roller rig,the test facility,testing process and test results are introduced in this paper.The testing process of the single wheelset derailment is simulated with computer.The problems about the single wheelset derailment are analyzed in detail,and it is found that the unloading rate of wheel load is one of main reasons of giving rise to derailment.
