In order to assess locomotive converter module’s ability to resist vibration environment, random vibration test should be made by the standard GB/T 21563—2008 in Class 1 B grade. This standard was summarized according to the European railway statistics derived from a large number of measured data. However, random vibration environment between European railway and our railway was different. Locomotive converter module random vibration acceleration data on the Beijing-Guangzhou line and the Lanzhou-Wulumuqi line were measured, induced, and calculated, acceleration power spectral density curve and acceleration root value were obtained. Finally, we proved that locomotive converter module measured random vibration test profile type and acceleration r.m.s. had some differences to the standard.
