| Abstract: | Large-scale flexible blades have obvious geometric nonlinear deformation problems during actual operation.In this paper,an aeroelastic model that is free vortex wake method coupled with FAST was established.The aerodynamic part was verified by the NREL Phase VI wind turbine.The coupled aeroelastic model was used to simulate two extreme conditions of wind turbine.The results showed that the free vortex wake method can simulate the aerodynamic changes of wind turbine blades better than BEM.The coupled aeroelastic model can simulate the structural response under extreme wind shear. |
