# 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.

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.

Finite element analysis of the cross-section of wind turbine blades; a comparison between shell and 2D-solid models. 1 Finite Element Analysis of the Cross-section of Wind Turbine Blades; a comparison between shell and 2D-solid models Daniel R. 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.

This paper presents an aeroelastic formulation based on the Finite Element Method (FEM) to predict the performance of an isolated horizontal axis wind turbine. Hamilton’s principle is applied to derive the equations of blade(s) aeroelasticity, based on a nonlinear beam model coupled with Beddoes-Leishman unsteady sectional aerodynamics. A devoted fifteen-degrees of freedom finite element, able to accurately model the kinematics and elastic behavior of rotating blades, is introduced and the spatial discretization of the aeroelastic equations is carried-out yielding a set of coupled nonlinear ordinary differential equations that are then solved by a time-marching algorithm. The proposed formulation may be enhanced to face the analysis of advanced blade shapes, including the presence of the tower, and represents the first step of an ongoing activity on wind energy based on a FEM approach. Due to similarities between wind turbine and helicopter rotor blades aeroelasticity, validation results firstly concern with the aeroelastic response of a helicopter rotor in hovering.

The present research evaluates the aero-structural response of multiple lay-up configurations of a 6 m blade by coupling computational fluid dynamics (CFD) and finite element analysis (FEA). The nominal operating conditions included a wind speed of 10.5 m/s and a rotational speed of 100 rpm, leading to a theoretical power output of 6591 W. For the proposed lay-up configurations, the Tsai-Wu and Puck (Global IRF) criteria were estimated and remained below the critical threshold of 1.0, indicating no risk of structural failure. However, some carbon fiber/epoxy layers, including unidirectional layers in the spar caps and bidirectional layers in the structural shear web, may present failure risks under extreme loading conditions. This applies to configurations with the lowest number of layers in the mid-span spar caps; this fact is reinforced by the main effects analysis.
