  1. 21. Bearing Diagnosis Using Fault Signal Enhancing Teqniques and Data-driven Classification

    University essay from Linköpings universitet/Fordonssystem

    Author : Benjamin Lembke; [2019]
    Keywords : Bearing diagnosis; rolling element bearings; predictive maintenance; signal processing; fault detection; gearbox diagnosis; support vector machine; svm; binary classification; one class classification; machine learning; feldetektion; diagnos; feldiagnos; växellåda; signalbehandling; maskininlärning;

    Abstract : Rolling element bearings are a vital part in many rotating machinery, including vehicles. A defective bearing can be a symptom of other problems in the machinery and is due to a high failure rate. Early detection of bearing defects can therefore help to prevent malfunction which ultimately could lead to a total collapse. READ MORE
