Abstract: Fast time-varying (FTV) phenomena, such as significant speed changes, FTV stiffness, and vibration signals with fast-oscillated instantaneous frequency (IF), carry critical fault information of high-speed rotating machines. ...

Abstract: Vibration signal analysis has been proved as an effective tool for condition monitoring and fault diagnosis for rotating machines in the manufacturing process. The presence of the rub-impact fault in rotor systems results ...

Abstract: This study aims at the comparative analysis and improvement of different analytical crack models for rotating blade. Part II of this study focuses on the comparative analysis of dynamic characteristics based on modified ...
