Bearing Fault Detection and Classification Using Artificial Neural Networks
<p>Bearings are the essential components of modern rotating machines. Bearing faults can cause severe machine damages or even breakdowns.</p> <p>In recent years, artificial intelligence and deep learning have been successfully applied to fault detection. In this thesis, convolutional neural …

Data-driven and Model-based Bearing Fault Analysis - Wind Turbine Application
This thesis is primarily about fault analysis for wind turbine generator bearings including vibration data analysis, and modeling of bearing outer race faults to understand how the vibration signal develops as the faults progresses. Case studies from large wind turbines are described where …

Electromagnetic flux monitoring for detecting faults in electrical machines
… motor to provide useful information about faults was investigated. The usefulness of this monitoring parameter was assessed in comparison with some other electrical parameters used for fault detection, such as stator phase current and circulating currents between the parallel branches of …

Vibration Analysis Processes In Noisy Environments For thePurposes of Condition Based Maintenance and theSignificance of Regime Recognition
… intent of this research was to monitor seeded fault bearings and differentiate those vibration signatures from the baseline and non-seed faulted bearings. The analysis was broken up into two sections ; baseline testing and seeded fault testing. It was quickly realized that studying vibration …

The structural architecture of seismogenic faults, Sierra Nevada, California; implications for earthquake rupture processes
Earthquake ruptures along tectonically active faults nucleate predominantly at depths of 5 to 12km in the crust, so the portions of faults that slip in these events cannot be directly observed. The geometry and composition of seismogenic faults controls the nucleation, propagation and termination …
