Physics-Guided Multi-Source Representation Learning for Aero-Engine Bearing Fault Diagnosis under Data Scarcity

This paper proposes the physics-informed dual-stream contrastive diagnostic network (PIDC-Net), a unified framework resolving both difficulties through three integrated mechanisms. The fault-physics encoding stream (FPES) constructs multi-scale depth-wise separable convolutional encoders whose receptive field width...
