Application of Order Cepstrum in Gear Wearing
In order to process the non-stationary vibration signals such as speed up or speed down signals effectively, a new method order cepstrum analysis to analyze the instantaneously signals in the rotate mechanism is explored. Firstly, the vibration signals at start-up in the gearbox are sampled at constant time increments in time-domain and then the data are resampled with software at constant angle increments in angle-domain. Therefore, the time domain instantaneously signals is changed into angle domain stationary ones. Then, the stationary ones are analyzed with order cepstrum. The outcome shows it can avoid effectively the “frequency smear phenomenon with order tracking technology, which cannot be solved with the traditional frequency spectrum method and the non-stationary signals are translated into stationary signals. It is trenchancy supplement for traditional spectrum analysis and has more amplitude appliance foreground.
