| Abstract: | This paper describes the acoustic emission detection technology used in fault diagnosis of the train truck bearing. Through the wavelet packet analysis the energy characteristics of AE signals of bearing extracted and with denoising by wavelet packet the energy feature is more prominent and is used to achieve better fault diagnosis. |
