Gearbox Fault Feature Extraction Using Hilbert Transform, S-Transform, and a Statistical Indicator
Download2007
Vibration analysis has been widely used in machine fault feature extraction and diagnosis of rotating machinery. The effects of modulation and nonstationarity in vibration signals collected from a faulty gearbox present challenges for fault feature extraction. Hilbert transform and S-transform...
