Özet

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. Then, the blade structure model is adapted a finite element solver, Ansys Workbench. Finally, loading conditions are applied along the blade and the results are obtained. The results of this study indicate that the internal flange is the main force-supporting part, while other parts of the blade are mainly keeping the blade stable.
