Abstract

The processing method of the non-stationary rotary machine vibration signal is studied. The angle domain signal is resampled from the time domain signal with interpolation algorithm. The time domain averaging method is preformed on the resampled signal to depress the noise uncorrelated to the axial frequency. The cepstrum analysis technique is introduced into the order analysis method to identify the periodic information hiding in the power spectrum. The gear tooth crack fault is diagnosed successfully. It shows that the techniques above are suitable and effective for analyzing the signal of the rotary.
