FAULT FEATURE EXTRACTION METHOD FOR ROLLER BEARINGS BASED ON LCD AND LOCAL HILBERT MARGINAL ENERGY SPECTRUM
Based on the definition of local Hilbert marginal energy spectrum,a fault feature extraction method for roller bearings is further proposed based on LCD and local Hilbert marginal energy spectrum. By using LCD,an original rolling bearing vibration signal could be adaptively decomposed into a number...
