Diagnosis for Rolling Bearing Nonlinear Fault Based on Daubechies Wavelet

摘要：

Rolling bearing is easy to be damaged in mechanism. In some case the fault has the nonlinear trait. The method of nonlinear fault diagnosis based on daubechies wavelet network is introduced briefly .And the application of wavelet packet analysis to the fault diagnosis of rotating machinery is studied. The pick-up of characteristics and fault diagnosis can be conducted in the pretreatment of the vibration signals with wavelets. Experiment result shows that the method is practicable for Rolling bearing
