| Abstract: | The theory and method of wavelet packet decomposition and its energy spectrum dealing with the fault of the connecting rod and its relative bearing of engine are presented in the paper. With the idea of traditional method of cutting off fire diagnosis, 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 demonstrates that this method is more advantageous and of practical value than traditional Fourier analysis method. |
| Keywords: | engine fault diagnosis wavelet packet energy spectrum |
