Abstract:WT5BZ]Aiming at the characteristic of unstability and time_variation of gearbox's acoustic signal,the wavelet packet theory is introduced into gearbox fault diabnosis,In the paper,the basic concepts of wavelet packet are briefly introduced.An example of acoustic signal processing and mechanical fault diagnosis via wavelet packet analysis is provided.The result demonstrates that the method is good for acoustic signal processing and fault diagnosing in gearbox.
