A Strategy to Conduct Numerical Simulation of Wind Turbine Considering the Soil-Structure-Interaction by Using a Coupled FEM-SBFEM Approach in Time Domain

摘要

In order to simulate wind turbines under different load scenarios, the computational model should take into account the aerodynamics of the rotor, the flexibility of tower, foundation and soil, transient operational phases and, first and foremost, the interaction of all these aspects. Whenever vibrations are emitted to soil, they induce waves traveling through the ground. Here, the main focus lies on the Soil-Structure-Interaction (SSI) effects on the dynamic behavior of operating wind turbines. The wind turbine with its foundation and the surrounding soil is modeled by a coupled Finite Element Method/Scaled Boundary Finite Element Method approach.
