Study of the wavelet packet transform method for fault diagnosis of six roller orientation clutch |
| |
| Abstract: | The theory and method of wavelet packet decomposition and its energy spectrum dealing with the fault of the overrunning clutch is presented in the paper. The characteristic frequency band of the fault could be identified by wavelet packet decomposition and its energy spectrum conveniently, at the same time,quantification analysis were performed.The result has shown that this method has more advantage and practical value than traditional FOURIER analysis method. |
