In response to stability issues caused by the dynamic response of wind turbines, in order to study the numerical response of the wind turbine under different wind speeds, a threedimensional structural model of the wind turbine is established based on SolidWorks, the blade root and tip particles are extracted, and the stress and displacement trends under different wind speeds are analyzed by using the finite element analysis method. The wind speed attenuation in the pendulum direction and the brandishing direction of the wind turbine is studied and the shear stress distribution of the flow field near the blade surface is discussed. The results show that the stress and displacement of blade tip and blade root have certain regularity under different wind speeds. When the natural wind passes through the wind turbine, the wind energy is effectively captured, and then shows regular attenuation. This study provides reference value for the dynamic parameters of wind turbine operation and improves the stability of wind turbine operation.
