Taking a 5 MW wind turbine blade as an example in our research, a rotor rotation simulation for the fluid-structure interaction is made. The combination of the wind rotation speed and the inflow velocity is simulated by considering the wind shear effect, and the torsion angles of the blade airfoil at different cross sections are modified, to establish the rotation simulation model of a wind turbine blade. The wind tunnel test of the wind turbine blade is simulated through a finite element software. The air pressure and the flow speed under the rotation effect around the blade together with the blade surface pressure are simulated. Using a data exchange platform to exchange the blade structure displacement and the surface pressure data, obtained through structure and fluid calculations, respectively, the fluidstructure interaction results are obtained. The results are compared with those at the rated wind speed and the reference experiment, and the rotation simulation method is verified.
