Among all kinds of gear fault diagnosis methods, the gear fault diagnosis method based on vibration detection has the advantages of simple measurement and strong real-time. Through measuring the vibration signal generated in the process of gear operation, as an important information source of fault diagnosis, it is an...

In the process of condition monitoring and fault diagnosis, we often use the vibration time domain signal directly to analyze and give the results, which is the simplest and most direct method, especially when the signal obviously contains simple harmonic component, periodic component or instantaneous pulse component. Of course,...
