Method and device for detecting fan bearing of wind power generation equipment

Abstract

The invention discloses a fan bearing detection method and device for wind power generation equipment, and the method achieves the mutual coupling of qualitative type recognition and quantitative severity evaluation in fault diagnosis through fusing the multi-source data of high-frequency vibration and weak impact, and introducing a dynamic differential equation as a physical constraint. And the physical credibility of the diagnosis result and the accurate characterization capability of the complex damage state of the bearing are obviously improved.
