Auto Gearbox Bearing Fault Diagnosis Method Based on Winger-SVD

Abstract:

A new auto gearbox bearing fault diagnosis method is put forward based on Winger distribution and SVD of vibration signal. Firstly, bearing vibration signal was analyzed by Winger distribution; then, signature sequence was obtained by SVD, which can reflect the gearbox fault condition; finally, singular values of the vibration signal Winger spectrums were selected as feature vectors to diagnose fault based SVM. Experiments show that this method can extract fault feature effectively.
