THE DEGENERATE STATE RECOGNITION METHOD OF ROLLING BEARING BASED ON LCD AND GMM-VPMCD HYBRID MODEL

THE DEGENERATE STATE RECOGNITION METHOD OF ROLLING BEARING BASED ON LCD AND GMM-VPMCD HYBRID MODEL

The key of the degenerate state recognition of roller bearing is feature extraction and pattern recognition. Local characteristic-scale decomposition（ LCD） is a new time-frequency analysis method,which is very suitably applied to the feature extraction of roller bearing vibration signal. Since varia...
