In order to research the end wal vibration problem of the CRH380B train when running on the line operation, the vibration test was executed. According to the test of the vibration acceleration data, first the relationship between the velocity and end wal vibration was analyzed in time domain. Secondly, the frequency method was used to analyze the main vibration frequency. Combining with time-frequency analysis, the source of vibration is identified, suggests are also proposed for vibration control.
