Abstract :
In this article, the challenges in condition monitoring and fault diagnosis of rotating machinery under speed-varying working condition is discussed. A general review is then given about the research progress of signal processing techniques dealing with non-stationary signal under that working condition. How to fully exploit the rich diagnostic information from the speed-varying processes is addressed. Some prospects are given finally.
