Fault Diagnosis for a Bearing Rolling Element Using Improved VMD and HT
The variational mode decomposition (VMD) method for signal decomposition is severely affected by the number of components of the VMD method. In order to determine the decomposition modal number, <i>K</i>, in the VMD method, a new center frequency method of the multi-threshold is proposed...
