Abstract :
Recent research shows fluid-structure interaction (FSI) problem becomes a key issue in the development of non-grid-connected wind turbines. In order to understand the mechanisms of FSI problem, this paper develops a numerical model based on boundary element method and finite element method. The boundary element method is used to calculate the unsteady aerodynamic forces acting on blades of the wind turbines. The finite element method is used to calculate the deformation and vibrations of the blade. The results show good agreement with the experiment data and prove that this model is suitable for understanding the FSI problem of the wind turbine.
