    Abstract : Wave ocean energy is a source of renewable energy which is gaining interest in the modern world. In contrast to other well-researched renewable energy sources such as wind energy, wave ocean energy is under the development phase. Governments around the world are encouraging the research of harnessing wave energy. READ MORE

  2. 2. Bearing condition monitoring : An investigation on the possibility of monitoring aging of the lubricating grease by means of acoustic emission and temperature.

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Dilesh Raj Shrestha; [2021]
    Keywords : Acoustic Emission; Fourier Transform; Infrared Spectroscopy; Condition Monitoring; Total Acidic Number; Fast Fourier Transform; Scanning Electron Microscopy; Rheology; Bleed Oil; Grease degradation;

    Abstract : Grease is among the most widely used lubricants in rolling element bearings. Proper understanding of the effect of lubrication due to grease aging can provide a significant increase in the life of the engineering systems. However, at present, there is no sufficient understanding of the grease aging effect in rolling elements bearing. READ MORE

  5. 5. 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
