A Gated Multi-Source Signal Fusion Method for Bearing Fault Diagnosis with a Fusion Negative-Transfer Suppression Mechanism
Experimental results demonstrate that the proposed negative-transfer-suppression diagnosis framework effectively achieves the design objective that “fusion outperforms non-fusion,” exhibiting strong noise robustness and high diagnostic accuracy under complex operating conditions.
