Application of LCD-SVD Technique and CRO-SVM Method to Fault Diagnosis for Roller Bearing

Targeting the nonlinear and nonstationary characteristics of vibration signal from fault roller bearing and scarcity of fault samples, a novel method is presented and applied to roller bearing fault diagnosis in this paper. Firstly, the nonlinear and nonstationary vibration signal produced by local...
