Convolutional Recurrent Neural Network for Fault Diagnosis of High-Speed Train Bogie

Figure 4

Comparison of EMD-AR spectra of the first 8 IMF components of bogie signals in 7 health conditions: (0) normal condition; failure of the air springs; failure of the antiyaw damper; failure of the lateral damper; failure of the air spring + the antiyaw damper; failure of the air spring + the lateral damper; failure of the lateral damper + the antiyaw damper.
