Application of multi-layer denoising based on ensemble empirical mode decomposition in extraction of fault feature of rotating machinery.
Aiming at the problem that the weak features of non-stationary vibration signals are difficult to extract under strong background noise, a multi-layer noise reduction method based on ensemble empirical mode decomposition (EEMD) is proposed. First, the original vibration signal is decomposed by EEMD,...
