Weak Fault Diagnosis of Wind Turbine Gearboxes Based on MED-LMD

Weak Fault Diagnosis of Wind Turbine Gearboxes Based on MED-LMD

In view of the problem that the fault signal of the rolling bearing is weak and the fault feature is difficult to extract in the strong noise environment, a method based on minimum entropy deconvolution (MED) and local mean deconvolution (LMD) is proposed to extract the weak fault features of the ro...
