A novel denoising method for bearing vibration signals in rotating machinery based on CEEMDAN-PSO-TV combined AWR and DRC

Puntos clave

• Improved denoising reduces noise in bearing vibration signals, enhancing signal clarity for analysis.
• The method shows reduced noise levels by up to 25%, demonstrating significant efficacy in signal preservation.
• Assessment using CEEMDAN combined with PSO, and applying AWR and DRC techniques systematically improves data accuracy.
• Highlights potential for better machinery monitoring and maintenance, reducing operational failures and costs.
