    The structural dynamic equations of blades were constructed for blades of wind turbines. The vibration velocity of blades and the relative flow velocity were calculated using the structural dynamics model. Based on the BEM (Blade Element Momentum) theory and traditional areodynamics, the coupling model for wind turbines including the aeroelastic and aerodynamics was developed. Finally, the computation was completed for a 2MW wind turbine. The vibration deflection, speed, acceleration and load of the blades are computed at the rating wind speed. The areodynamic model of wind turbines becomes more accurate because of the coupling analysis between the vibration speed of blade and the wind speed. The results have very significance to the design of wind turbines.
