A fault diagnosis method for aero-engine inter-shaft bearings based on 1DCNN-Transformer-BiGRU.
Experimental validation on the Harbin Institute of Technology aero-engine inter-shaft bearing dataset shows that the proposed model achieves 97% diagnostic accuracy under extreme noise conditions (SNR = -5 dB).
