| Abstract: | Energy analysis on fault signals of rotary machinery in TRT by spectrum method was used, Extract feature vectors and main fault table of power spectrum that reflect running of TRT, The monitoring and diagnostic software of fault diagnosis module is designed. The actual diagnosis result shows that the fault diagnosis is effective by using the fault signal feature vector and fault table and similarity theory. |
