| Abstract: | With the dynamic stress measurement in on-track testing of a certain bogie for Shanghai Metro,the frequency features of typical signals are analyzed,the filter of different frequencies is applied for the dynamic stress data of bogies,the signal data after filter are compared,and with the sampling the- orem,the filtering and sampling frequencies applica- ble to the load measurement of metro bogies are put forward. |
