Research On Fault Diagnosis Method Of Steam Turbo-Generator Shafts Based On Information Fusion

Based on the thoroughly analysis of development background application scope andthe advantage in modality recognition of multi-information fusion, the paper has donethe analyzed work on the method of multi-information fusion. In view of the requirementin Fault diagnosis with Steam Turbo-Generator Shafts and according to the informationsystem structure, the application technique methods of various levels are researched indepth .By synthesis classification of fault information, A new information-fusion levelprocess and system model on fault diagnosis of Steam Turbo-Generator Shafts isintroduced. This paper put focus on the holo-spectrum method under data-fusion leveland information entropy method under characteristic level. Put the two applications onthe system of vibration monitoring and fault diagnosis. Distinctively analyzed with rotortemporary curving and rubbing conditions, which can process the diagnosis inferencewell and reach the expected results.
