Abstract
The principle and application of wavelet analysis and gearbox fault diagnosis are described in the paper. To the experimental measurement of gearbox vibration signal, the time-domain and frequency-domain signals are got by wavelet transform. Then it get a clearly gearbox vibration signal by wavelet de-noising. The residual signal processing and three-dimensional wavelet analysis, it get the failure frequency and determine the fault characteristics. By the experimental signal wavelet transform, it reflects that the wavelet analysis method is better than traditional Fourier transform, so it is an effective method of fault diagnosis.
