WebMar 24, 2024 · However, bearing fault diagnosis during various working conditions is challenging; catastrophic forgetting occurs when test data are gathered under different conditions. In this paper, we develop an incremental learning-based multi-task shared classifier (IL-MTSC) for bearing fault diagnosis under various conditions. WebSharp speed variation leads to a shift of sample distribution domain, which poses a challenge for vibration-based rolling bearing fault diagnosis. Furthermore, the overfitting effects inflicted on the intelligent diagnosis model due to insufficient data will hinder the performance significantly. In …
