Rolling bearing fault diagnosis based on RQA with STD and WOA-SVM

Rolling bearing fault diagnosis based on RQA with STD and WOA-SVM

A rolling bearing fault diagnosis method based on Recursive Quantitative Analysis (RQA) combined with time domain feature extraction and Whale Optimization Algorithm Support Vector Machine (WOA-SVM) is proposed. Firstly, the recurrence graph of the vibration signal is drawn, and the nonlinear featur...
