Rotor System Fault Diagnosis Based on Wavelet Packet Analysis and CBR

The poor explanation of fault diagnosis results and dependence of fault analysis on specialized experience for complicated rotor system wavelet packet method were solved by incorporating wavelet packet analysis and CBD into the rotor system fault diagnosis. The explanation of fault diagnosis results was improved by the case that rotor system fault was characterized with fault characteristic extractedusing wavelet packet technology and in the processs of dealing with the present problems using similar casesobtained from retrieval technique. The simulation results prove the validity of the method.
