Rotating machinery fault classification Via the difference degree
Yin Zhan-wen · Journal of Henan University of Urban Construction · 2012
Aiming at the fault and normal condition of rotational vibration signal in the presence of the same frequency and different characteristics,a difference degree separation method has presented based on the theory of Hilbert Huang transform(HHT).Screening out the useful component IMF via the presented method,and chase down the IMF components of the energy characteristics.Then send the series of eigenvector into the classifier,which can real-time,high efficiency to the diagnosis and fault classification of the rotating machinery.
