The Ply Optimum Design of Composites Wind Turbine Blade Based on the Local Stability

Abstract:

Fluid-solid coupling calculations are performed on design of a wind turbine blade made by fiber reinforced polymer composites. The length of the blade is 46m, and it is for a 3MW-capacity power station. By the finite element method, the initial design on the ply is carried out under the case of static loads. Then, the eigenvalue buckling theory is used to analyze the stability. In the process of design, sections of the blade which have different stiffness have different ply orientation and thickness. Thus, the local structural stiffness is enhanced, and the local stability of the blade is improved. The results show that the buckling load coefficient increases from 3.3 to 4.2, and the weight of the blade reduces by 4.5%. The aim of optimization design on the wind turbine blade has been achieved.
