A Wavelet Transform-Based Transfer Learning Approach for Enhanced Shaft Misalignment Diagnosis in Rotating Machinery

Electronics, Год журнала: 2025, Номер 14(2), С. 341 - 341

Опубликована: Янв. 17, 2025

Rotating machines are vital for ensuring reliability, safety, and operational availability across various industrial sectors. Among the faults that can affect these machines, shaft misalignment is particularly critical due to its impact on other components connected shaft, making it a key focus diagnostic systems. Misalignment lead significant energy losses, therefore, early detection crucial. Vibration analysis an effective method identifying at stage, enabling corrective actions before negatively impacts equipment efficiency consumption. To improve monitoring efficiency, essential system not only intelligent but also capable of operating in real-time. This study proposes methodology diagnosing by combining wavelet transform feature extraction transfer learning fault classification. The accuracy proposed soft real-time solution validated through comparison with time-frequency transformation techniques networks. includes experimental procedure simulating using laser measurement tool. Additionally, evaluates thermal vibration signature each type multi-sensor monitoring, highlighting effectiveness robustness approach. First, used obtain good representation signal domain. step allows features from signals. Then, network processes different layers identify their severity. combination provides decision-support tool faults, monitoring. tested two datasets: first public dataset, while second was created laboratory simulate alignment demonstrate effect this defect imaging. evaluation carried out criteria methodology. results highlight potential implementing faults.
