Fault Diagnosis of Rolling Bearing of Wind Turbine Based on VMD and Different Envelope Order Structure

In order to identify the faults of rolling bearing of wind turbines, the variational modal decomposition (VMD) was combined with two methods, including calculation order tracking (COT) and reversed sequence squared envelope spectrum (RE-SES), to carry out the envelope order analysis. The non-station...
