| Abstract: | The theory and method of wavelet packet decomposition and is energy spectrum dealing with the fault of the overrunning clutch are presented in the paper.The characteristic frequency band of the fault can be identified by wavelet packet decomposition and its energy spectrum conveniently,and the quantification analysis are then performed.The results show that this method is of practical value and more advantageous than traditional Fourier analysis method. |
