Bearing Fault Diagnosis Based on Optimal Morlet Wavelet
Year: 2009
Type: article
Abstract: A fault diagnosis method based on Morlet wavelet and thresholding denoising is proposed to diagnose rolling bearing fault in high noise condition.The optimal Morlet wavelet base function is determined according to kurtosis maximization criteria.The continuous wavelet transformation and soft threshold methods are used to denoise vibration signals.Experiments show that the proposed method is valid for de-noising,and it can effectively extract fault feature from vibration signals.
