Embodiment Construction
[0063] Diagnosis graphic information has been effectively used. In the past fault diagnosis, due to the difficulty of graphic feature extraction, it is difficult to be directly used in the fault diagnosis of rotating machinery, so the diagnostic accuracy is low. The invention constructs fuzzy soft morphological parameter graphic feature extraction and preprocessing methods, which can effectively obtain vibration information and improve the accuracy of fault diagnosis.
[0064] The invention relates to the field of high-speed rotating machinery fault diagnosis technology and signal processing technology. It is the first domestic rotating machinery fault diagnosis method based on fuzzy soft morphology graphic recognition technology, and can be applied to petrochemical, metallurgy, electric power, aviation and aerospace industries. Some large rotating machinery as the main production tools such as aero-engines, gas turbines, fans, steam turbines, compressors and generators.
