J. Cent. South Univ. (2016) 23: 1961-1969 DOI: 10.1007/s11771-016-3253-3 A bearing fault diagnosis method based on sparse decomposition theory ZHANG Xin-peng(张新鹏), HU Niao-qing(胡茑庆), HU Lei(胡雷... on sparse decomposition theory is proposed. Certain over-complete dictionaries are obtained by training, on which the bearing vibration signals corresponded to different states can be decomposed sparsely......
