Abstract
Considering fault impulse signals of rolling element bearings have the features of periodicity and easily to be immerged by background noise, a novel fault feature extraction method based on the wavelet packet transform (WPT) and the time-delay correlation demodulation analysis is proposed in this paper. Firstly, the signal-to-noise ratio (SNR) and the root-mean-square error (RMSE) are used as the criterion to select the optimal wavelet packet parameters to enhance the SNR of the vibration signal. Then, the denoised signal is reconstructed for further analysis. Finally, the fault features of the reconstructed signal are extracted using time-delay correlation demodulation analysis. The results show that the fault characteristic frequencies can be extracted with higher accuracy based on the simulation and experimental studies, respectively. It can be concluded that the proposed method has more effectiveness and feasibility for fault diagnosis of rolling element bearing with higher accuracy.
