Abstract :
The bi-cepstrum technique is presented based on bi-spectrum and cepstrum analysis. This new method combines bi-spectrum technique with cepstrum analysis. Firstly, in order to eliminate the noise effects, the bi-spectrum is calculated. Then the bi-spectrum is processed by bi-cepstrum technique. The experimental results show that bi-cepstrum technique can effectively diagnosis the faults of the gear.
