Abstract

The vibration signal of rotating machinery under time-varying working conditions presents time-varying characteristics. Entropy measure has unique advantages in extracting features from this type of signal. To make up the defects of low calculation efficiency and unstable complexity estimation of traditional entropy method, proposed a fault diagnosis method of rotating machinery under time-varying working conditions based on refined composite multiscale diversity entropy. The proposed method can extract more comprehensive fault feature information and improve the diagnostic accuracy. Firstly, the time domain signal is resampled into angular domain signal, and variational modal decomposition and independent component analysis is used to denoise the angular domain signal. Secondly, the refined composite multiscale diversity entropy is used to extract the features of the denoised signal. Then the extracted features are input into the LR (Logistic Regression) classifier to identify fault type. Finally, the proposed method is verified by gear experiments under time-varying conditions. The results show that the proposed method can effectively improve the diagnostic accuracy under time-varying conditions.
