Application of Improved EWT Method in Bearing Fault Diagnosis of High-speed Train

It is difficult to extract fault features of axle box bearings of high-speed train. To solve this problem, an improved empirical wavelet transform based on spectrum trend and frequency band combination was proposed and applied to the fault diagnosis of high-speed train bearings. Firstly, by using em...
