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.roneverhart.com/Short-Porch-Mortar-USSSA-Pro-M-12-Slowpitch-Softballs/
