Vibration alleviation for wind turbine gearbox with flexible suspensions based on modal interaction
Journal of Low Frequency Noise, Vibration and Active Control, 2023 Wind turbine drivetrains play a fundamental role in converting wind power into electrical energy. The gearbox is one of the most important and expensive components in a wind turbine drivetrain. Since flexible suspensions mounted on the gearbox are mainly

Minimum friction losses in wind turbine gearboxes [PDF]
Forschung im Ingenieurwesen, 2021 AbstractImproving the mechanical efficiency is not the most important objective in the design of wind turbine gearboxes since the available wind energy is abundant and costless. The most important criteria for dimensioning the gearbox are the fatigue strength—bending and pitting—, noise emission, vibrations, and maintenance requirements.
