In this research, a wind turbine blade structure is analyzed by using finite element analysis software . First establish ANSYS software model of the wind turbine blades at the same time verify the accuracy of the model, and then reduced the wind pressure into the point loadings applying on the blade model to simulate the stress of different inclination of angles of the wind turbine, to identify the smallest of the blade angle of inclination, at the same time analyze different structure of the blades.
