Fault Diagnosis of Rolling Bearings based on VMD and Symmetric Difference Energy Operator Demodulation

Fault Diagnosis of Rolling Bearings based on VMD and Symmetric Difference Energy Operator Demodulation

Aiming at the problem of rolling bearing early fault vibration signals non-stationary and high noise,failure frequency is difficult to extract. A fault diagnosis method of rolling bearings based on the Variational Mode Decomposition（ VMD） and symmetric difference energy operator is proposed. First o...
