| Abstract: | The basic conception of fault diagnosis is introduced. Especially,the theory of nonlinear Spectral Analysis and its application in the field of fault diagnosis are illustrated. Based on this theory,the design of mechanism fault diagnosis instrument has been accomplished. In this system,the GFRF (Generalized Frequency Response Functions) spectral features are used as the fault features .The structure and diagnosis principle of the system are illustrated.The design of the instrument's hardware is also provided. Finally the experiment results indicate that the presented method is efficient. |
