Fault Diagnosis of Spindle Device in Hoist Using Variational Mode Decomposition and Statistical Features [PDF]

open access: yesShock and Vibration, 2020
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), SVM, and ...
