Fault Diagnosis of Rolling Element Bearing Based on BiTCN-Attention and OCSSA Mechanism

Fault Diagnosis of Rolling Element Bearing Based on BiTCN-Attention and OCSSA Mechanism

This paper proposes a novel fault diagnosis framework that integrates the Osprey–Cauchy–Sparrow Search Algorithm (OCSSA) optimized Variational Mode Decomposition (VMD) with a Bidirectional Temporal Convolutional Network-Attention mechanism (BiTCN-Attention). To address the limitations of empirical p...
