Negentropy Spectrum Decomposition and Its Application in Compound Fault Diagnosis of Rolling Bearing
The rolling bearings often suffer from compound fault in practice. Compared with single fault, compound fault contains multiple fault features that are coupled together and make it difficult to detect and extract all fault features by traditional methods such as Hilbert envelope demodulation, wavele...
