NC MACHINE FAULT DIGNOSIS BADED ON LCD MULTI DISPERSION ENTROPY

In order to improve fault diagnosis effect of bearing used in NC machine, a fault feature extraction and diagnosis method of bearing based on LCD multi dispersion entropy was proposed. The vibration signal was decomposed adaptively with local characteristic-scale decomposition(LCD) to obtain the com...
