Abstract
Rolling Element Bearing (REB) failures represent a major challenge in the maintenance of rotating machinery, as they compromise the reliability and operational continuity of systems. The analysis of vibration signals at the bearing level provides an effective approach for the early detection of anomalies and their classification, thereby helping to anticipate breakdowns and enhance equipment safety. In this work, the the well-known bearing dataset of Case Western Reserve University (CWRU) is utilized to perform fault classification using four machine learning algorithms: K-Nearest Neighbors (KNN), Decision Tree (DT), Random Forest (RF), and Gradient Boosting Decision Tree (GBDT). The study particularly addresses feature extraction in the time domain, such as root mean square (RMS), standard deviation, kurtosis, and other statistical indicators.
Results show that using statistical vibration features with ensemble classifiers is a good way to diagnose multi-class bearing faults and establishes a comprehensive benchmark for ML- and DL-based rolling bearing FDD.
