Fatigue reliability of wind turbines: historical perspectives, recent developments and future prospects

“…The gearbox is one of the costliest parts of a wind turbine system, and generally shows higher-than-expected failure rates in the wind energy industry [109,110]. Contact failures in gears have been the sources of costly repairs and downtime of the turbine drivetrain [111].…”

Digital Twin-Based Approach for a Multi-Objective Optimal Design of Wind Turbine Gearboxes

“…Eventually, WT gearbox failure detection and remaining useful life (RUL) prediction have been tackled using a wide range of techniques, comprising machine and deep learning, finite element modeling, Bayesian inference, supervisory control and data acquisition (SCADA) systems, and physics-informed models, etc. [8][9][10][11][12].…”

Fluid–Structure Interaction Analysis in Ball Bearings Subjected to Hydrodynamic and Mixed Lubrication

“…Also, the failure of one element can generate losses in others. So, in effect, a USD 5000 bearing failure in a wind turbine can cost a USD 250,000 project, which will involve cranes, a service crew, gearbox replacements, generator rewinding, and downtime and loss of power generation, which also represent increased cost loss [6][7][8].…”
