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.bekindtopets.com/top-super-Harry-Potter-Hufflepuff-Big-Bang-Lite-Headband-quick-super/
