The damaged gearbox is often related to non-linear effects that may lead to non-linearity in the machine vibration signal. This paper introduces the application of modern signal processing technique based on higher order spectrum to the fault detection and diagnosis of gearbox. The bi-spectrum can effectively eliminate the effect of random noise and extract useful features from the noisy mechanical...
The speed-up and speed-down of the gearbox are non-stationary process and the vibration signal can not be processed by traditional processing method. In order to process the non-stationary vibration signals such as speed-up or speed-down signals effectively, the order envelope analysis technique is presented. This new method combines order tracking technique with envelope spectrum analysis. Firstly,...
