Denoising method of machine tool vibration signal based on variational mode decomposition and Whale-Tabu optimization algorithm
Abstract The noise from other sources is inevitably mixed in the vibration information of CNC machine tools obtained using the sensors. In this work, a de-noising method based on joint analysis is proposed. The variational mode decomposition (VMD), correlation analysis (CA), and wavelet threshold (W...
