Abstract
Designing horizontal axis wind turbine (HWAT) blades achieves satisfactory levels of performance, starts with knowledge of the aerodynamic forces acting on the blades. In this paper, HWAT blade design is studied from the aspect of aerodynamic view and the basic principles of the aerodynamic behaviors of HWATs are investigated. Aiming at the dynamic performance analysis of aluminum alloy blade, a three-dimension modeling method with ANSYS 14.5 is proposed to the actual layer structure and the blade shape parameters are obtained. The important aerodynamic parameters which decide the efficiency of the wind turbine blade are analyzed for the NACA 4420 airfoil which is used to model the blade from root to tip. The airfoil has high lift to drag force ratio at small angle of attack of 50, even at low Reynolds number. The dynamic analysis is performed for the blade by using the Finite Element Method (FEM). The study has been successfully applied to the static analysis of the blade. Moreover, stress analysis of blade is carried out by finite element numerical analysis and stress distribution is obtained. At last, Strength checking for wind turbine blade is also achieved. The results of the analysis are reference for wind turbine blade loads research. In order to reduce the stress on the blade the thickness of the blade skin is varied to achieve reduced stress and less bending stress at the time of deflection of blade due to high speed winds.
