Harmonic Wavelet Packets Method and Its Application to Signal Analysis of Rotating Machinery
The application of wavelet analysis in fault diagnosis is growing rapidly. This paper examined the advantages of harmonic wavelets and realized the capability of analyzing harmonic wavelet on arbitrary detail of frequency section. The simulating signal can be extracted effectively in frequency domain by harmonic wavelet packet transform and can easily be reconstructed in time domain. This paper has obtained good results by analyzing the rubbing vibration signal of turbine-generator units, thereby providing a new method for fault diagnosis of rotor rubbing.
