踏面磨耗对高速列车转向架构架垂向载荷特性影响研究

Research on the Effect of Tread Wear on Vertical Load Characteristics of High-Speed Train Bogie Frame

本文提出了一种高速列车垂向载荷测试方法,通过运行线路测试,获得了踏面磨耗前后的垂向载荷时间历程。从时域和频域分别分析了高速列车通过直线、道岔、进出车站等典型运用工况下的垂向载荷特性,进而编制了高速列车转向架构架垂向谱。

A vertical load test method for high-speed trains was presented in this paper, the loads, under the new state and worn state of the profile, were achieved through experiments. The test data of typical working conditions of high speed trains through straight lines, turnouts, passing in and out stations were analyzed both in the time domain and in the frequency domain in order to evaluate the effect of profile wear on load characteristics of bogie frame and the load spectrum of vertical load was established.
