摘要

In this paper, an advanced aeroelastic numerical tool for horizontal axis wind turbines (HAWT) is presented. The tool is created by coupling an unsteady aerodynamic model based on the lifting-line approximation with an elastodynamic model based on the beam approximation. The coupling is non-linear in the sense that at every time step the two models interact through data transfer from the one to the other. Two interfaces assure a constant communication between the two parts of the complete model. The aero-to-elastic interface defines the loads exercised on the structure, whereas the elastic-to-aero interface transmits the rates of deformations. The aeroelastic model is evaluated through comparisons of its predictions with experimental data as well as with predictions obtained by simpler models.
