Soil-structure-drive train interaction

Traditional design guidelines recommend the separation of the lowest resonance frequencies for the components and the overall system. A sufficient offset to the low order excitation frequency is advised. Due to the fact that for high-capacity purposes higher and slender towers will be built, these guidelines are not sufficient anymore. However, an optimal design and a perfect match of the operational components can only be achieved by the dynamic analysis of the overall system. Hence, the aim of the project is to investigate the dynamic behavior of the overall system to account for the interaction of aerodynamics, dynamic of the engine and structural dynamics of the tower including soil-structure interactions. In particular it includes the consideration of the dynamic behavior for single components like the rotor, drive train, tower construction as well as its foundation and the soil. The results will lead to an optimal design of the wind turbine to increase fatigue and abrasion behavior and thus down time and maintenance work is minimized. The project intends to quantify the impact of the soil-structure-drive train interaction and will provide recommendations for the design of wind turbines and will give rise to the loading conditions for full size nacelle test rigs.
