The Wheel Flat Identification Based on Variational Modal Decomposition—Envelope Spectrum Method of the Axlebox Acceleration

The wheel flat can cause train and rail system infrastructure damage and endanger the running safety. To monitor the early wheel flat, it is urgent to carry out the theoretical basic research on the relationship between the vibration signal and the wheel flat. Moreover, to extract the characteristic...
