Planetary gearboxes often run under time-variant conditions, thus resulting in nonstationary signals. How to extract fault features from nonstationary vibration signals is a key issue of planetary gearbox fault diagnosis. Considering the merits of reassigned wavelet scalogram, i.e. fine time-frequency resolution and free from cross term interferences, it is used to analyze the vibration signals in...
It was observed that the measurement signals contained some undesired parts in engine mass characteristic measurement test by single pendulum method, which brought some difficulties for extracting parameters of engine mass characteristic. The useable signals were separated from the undesired signals through the wavelet multi-resolution-analysis. Some parameters of the engine system such as the natural...
Vibration data analysis plays a critical part in condition monitoring for fault detection, diagnostics and condition based maintenance (CBM) purposes. This requires development of effective methods for analyzing vibration data. A literature review has shown that while there exists a body of literature on vibration data analysis techniques of gearboxes with fixed-axis gear sets, techniques for gearboxes...
