By analyzing nonlinear and nonstationary vibration signals from the spindle device of the mine hoist. it is a challenge to overcome the difficulty of fault feature extraction and accurately identify the fault of rotor-bearing system. In response to this problem. this paper proposes a new approach based on variational mode decomposition (VMD). https://www.markbroyard.com/super-pick-beer-mug-washer-1-each-for-discount-flash-find/
