... of the main shaft bearing to predict the bearing replacement period, from the perspective of an inverse problem, considering the influence of bearing type and other factors, based on data mining technology and prediction methods, we propose a grey periodic extension model combined with multi-scale graph...

...Yujie Cheng; Hang Yuan; Hongmei Liu; Chen Lu Purpose The purpose of this paper is to propose a fault diagnosis method for rolling bearings, in which the fault feature extraction is realized in a two-dimensional domain using scale invariant feature transform (SIFT) algorithm. This method...
