Abstract

The modal analysis based on ANSYS for all the components of the train wheel-bearing of NJ(P)3226X1 had been carried out. The vibration of each component was excited by the hammer with an accelerometer. The respondent acoustic signals were acquired by the microphone and the natural frequencies were obtained. The comparison between the computation using ANSYS and the measurements had demonstrated the reliability of the results which provided the reference data for further research in fault diagnosis of the bearing.
