Fault feature extraction of wind turbine gearbox under variable speed based on improved adaptive variational mode decomposition

This paper proposes a study on gearbox fault feature extraction of wind turbine under variable speed condition using improved adaptive variational mode decomposition (VMD). Frequent changes in wind speed and critical noise interference make the vibration signal exhibit non-stationary characteristics...
