CESIgram: A Fault Feature Extraction Method for Rolling Bearings in Wind Turbine Equipment Based on Collaborative Filtering Correlation Spectrum
To address the difficulty of extracting weak fault features of rolling bearings in wind turbines under strong background noise, a fault feature extraction method based on the collaborative filtering correlation spectrum, named CESIgram, is proposed. The collaborative filtering correlation spectrum (CFCS) based on Block...
