Abstract

Aiming at the non-stationary features of mechanical vibration signals, a fault diagnosis method based on ensemble empirical mode decomposition singular value entropy and support vector machine are put forward. This method utilizes the advantage of EEMD which can effectively restrain model mixing and combined with information entropy theory, firstly, original signals were decomposed into a finite number of stationary intrinsic mode functions (IFMs). Secondly, singular value and singular entropies of a feature pattern matrix whose rows are IMFs are extracted. Finally, singular value feature vector are served as the input vectors of SVM, based on the output to identify the fault pattern. Experimental results show that this method is affective.
