# 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.

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.

Structural Dynamics Analysis and Model Validation of Wind Turbine Structures D. Todd Griffith* Sandia National Laboratories†, Albuquerque, New Mexico 87185 The focus of this paper is the development of validated structural models of wind turbine structures and their substructures. A typical modern wind turbine is a large structure composed of a single tower, a nacelle located atop the tower which houses the drive train mechanical components, and three rotor blades. In very broad terms, a wind turbine design team must consider the dynamic response of the full system in the design process along with detailed design for each individual substructure. Blades are a critical substructure of a wind turbine as they carry large loads in capturing the energy from the wind, and must be designed to maximize performance and reliability while minimizing their cost. First, we discuss the structural dynamics analyses that are performed to design a modern wind turbine structure. Results from recent tests and validation of models for these blades will be presented.
