# A Finite Element Structural Analysis of Wind Turbine Blade. 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 5 0 , even at low Reynolds number. The dynamic analysis is performed for the blade by using the Finite Element Method (FEM). 1. The study employs Finite Element Method (FEM) for dynamic performance analysis of wind turbine blades.
We propose an improved finite element (FE) simulation-based methodology of to evaluate the structural integrity of a large sized composite wind turbine blade.
1. The basic principle and analysis method of finite element design method. The finite element design method is a very effective numerical method for solving boundary value problems of differential equations, and it is also one of the core technologies of CAE software. The finite element design method is a numerical discretization method, and the numerical solution is carried out according to the variational principle. The basic idea of the finite element design method is to simplify the structure on the basis of the structural analysis and force analysis of the overall structure, and use the discretization method to treat the simplified continuous structure as consisting of many finite sizes, only within each other. The steps of structural analysis with finite element design method are: discretization processing, unit analysis, overall analysis, and introduction of boundary conditions to solve. In the finite element design analysis, the correct selection of element types plays an important role in the correctness of the analysis results and the calculation accuracy.

Email kibr@dtu.dk ABSTRACT A very detailed 2D-solid finite element model is developed representing the load carrying box girder of a wind turbine blade. Keywords: FEA model, Wind turbine blade, Box girder, Strain and stress, Non-linear analysis. 6 CONCLUSIONS In the analysis of wind turbine blade structures, shell models and the detailed 2D model is found to give similar results for the deflection, the stain and the stress in regions were there is ‘pure bending’. However, large differences in the calculated strain and stress can occur between the shell models and the more realistic detailed 2D-solid model, especially in regions where the loading is dominated by shear.

Modal and static analysis is performed in order to obtain static and dynamic behavior of the blade. To perform analysis, the geometric three-dimensional model of the blade is obtained by using two-dimensional drawings of the blade. After geometric modeling of the blade, the materials that are used in blade structure are applied to Ansys ACP.
