Sparse Envelope Spectra for Feature Extraction of Bearing Faults Based on NMF
Periodic impulses and the oscillation response signal are the vital feature indicators of rolling bearing faults. However, finding the suitable feature frequency band is usually difficult due to the interferences of other components and multiple resonance regions. According to the characteristics of...
