Application of optimized VMD in fault diagnosis of motor bearings of high-speed train
Aiming at the difficulty in extracting early faults of high-speed train motor bearings under the background of strong noise, an optimized VMD algorithm was proposed. Firstly, the vibration signal spectrum trend was obtained according to the spectrum trend estimation algorithm, thereby the resonance...
