文章结合上海地铁某转向架线路试验动应力测试结果,分析了典型信号的频率特性,对转向架动应力数据采用不同频率滤波,对滤波后的信号数据进行了比较,并结合采样定理提出了适用于地铁转向架荷载测试的滤波和采样频率。
In this paper, the test results of the dynamic stress of a bogie line in Shanghai Subway are analyzed. The frequency characteristics of the typical signals are analyzed. Different frequency filtering is used to analyze the dynamic stress data of the bogie. The filtered signal data are compared. Based on the sampling theorem, Filtering and sampling frequency for metro bogie load testing.
