摘要
Variable-speed operation changes the frequency locations and response distributions of fault-related components, making frequency-domain features extracted from different vibration records difficult to compare consistently. To address this issue, this paper develops a bearing fault diagnosis method based on filter bank construction and complementary frequency-band feature fusion. Frequency ranges that remain persistently active within individual training records and recur across different records are identified and aggregated into a bandpass filter bank. The resulting filter bank remains fixed during testing, providing a common frequency reference for different vibration records. Within the retained bands, band contribution ratio, centered band contrast, and raw-envelope impact consistency are extracted to characterize different aspects of the vibration response. These complementary frequency-band features are fused into a compact representation for diagnostic classification, yielding a consistent frequency-band representation across different variable-speed conditions.
