Research on Mechanical Faults with Application of 1(1/2) Dimensional Spectrual Coupling Features in Fault Diagnosis

Abstract:

In mechanical engineering,although mechanical vibration is extremely complicated, each mechanical fault signal produced by it has its own inherent features. Three-order cumulant can reduce the Gaussian background noise automatically, its complex formal includes different coupling information of its signal, in the experiment, through these different coupling modes, the same coupling components are fetched from specific fault signal and normal signal, then these components are used to diagnose that certain mechanical fault. The results shows, the method can diagnose mechanical fault effectively.
