| Abstract: | Wavelet had good time-frequency localization properties.The refined spectrum could be approximated by its multi-resolution nature.Therefore,it played a remarkable role in fault signal extraction.The research and application of wavelet analysis in fault diagnosis was systematically discussed.The fault diagnosis method using wavelet analysis to process signal was focused on.Through the computer simulation,this method was confirmed feasible in the motor failure diagnosis. |
