Target Label-Free Diagnosis of Rotor Bolted Joints via a Hybrid Physical-Data-Driven Partial Domain Adaptation Framework
Flange bolted joints are widely used in the rotor systems of aeroengines. Intelligent fault diagnosis of these bolted joints is crucial for ensuring operational safety. However, due to the extreme scarcity of real-world fault cases, deep learning-based fault diagnosis methods are difficult to apply in engineering pract...
