AMSC Module
Adaptive Multi-Scale Convolution for weak fault feature enhancement.
The Adaptive Multi-Scale Convolutional (AMSC) module dynamically adjusts fusion weights for different signal scales, enhancing key temporal features while suppressing operational interference. This self-learning weighting strategy overcomes limitations of fixed-kernel approaches under variable operating conditions.
Transformer
Explicit Temporal Dependency Modeling for long-range fault evolution.
The Transformer encoder explicitly captures long-range temporal dependencies and fault evolution patterns across multiple rotation cycles, complementing convolutional local feature extraction and improving diagnostic stability in compound-fault and noisy scenarios.
CBAM
Feature Refinement for enhanced discrimination & noise robustness.
The Convolutional Block Attention Module (CBAM) is applied after the Transformer to improve feature discrimination and noise robustness by emphasizing key features and suppressing noise through channel and spatial attention.
