Study on Fault Feature Extraction of Rolling Bearing Based on Improved WOA-FMD Algorithm

The vibration signal of rolling bearing fault is nonlinear and nonstationary under the interference of background noise, and it is difficult to extract fault features from it. When feature mode decomposition is used to analyze signals, prior parameter settings can easily affect the decomposition res...
