Wind turbine blade performance directly influences the efficiency and reliability of wind energy conversion systems. The study focuses on structural and aerodynamic performance, aiming to reduce blade weight while maintaining mechanical strength and minimizing deformation under operating loads. A parametric blade model was developed and analyzed using FEA to evaluate stress distribution, deformation, and natural frequency. The results demonstrate significant weight reduction potential with improved structural performance, offering valuable insights for sustainable wind turbine blade design.**. **Wind turbine blade, finite element analysis, structural optimization, aerodynamic performance, blade design, stress analysis**.

# 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.

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).

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.

Static analysis of a composite wind turbine blade using finite element model VII International Conference on Computational Methods in Marine Engineering MARINE 2017 M. Le Touze (Eds) 1 STATIC ANALYSIS OF A COMPOSITE WIND TURBINE BLADE USING FINITE ELEMENT MODEL Meltem ÖZYILDIZ1, Demirkan COKER2 1 Graduate Student, Dept. of Aerospace Engineering Department, METU, 06800 Çankaya Ankara/TURKEY, e-mail: coker@metu.edu.tr Keywords: Composite Materials, Finite Element Analysis, Static Analysis, Wind Turbine Blade Abstract: This study is presented here that the stress characteristics of an existing 5-meter composite wind turbine blade for 30 kW wind turbine designed for METUWIND is known by using finite element method. 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.

Regarding the beam model, due to geometric complexity of typical cross-sections of wind turbine blades it is adopted a theory that allows creation of arbitrary multicellular cross-sections.
