طراحی بهینه، مدل سازی و تحلیل دینامیکی برای تیغه توربین بادی کامپوزیت

The aerodynamic contour design and performance analysis of wind turbine blades are important parts of the design theory and application of wind turbine. Taking 20KW the horizontal axis wind turbine blade as an example, the program for optimization design of the blade's aerodynamic contour has been solved in this paper using MATLAB tool, based on the design process of Wilson method. According to the space coordinate transformation theory, the space coordinates of the blade elements have been calculated .Aiming at the dynamic performance analysis of composite blade, a modeling method of combining SolidWorks with ANSYS was proposed referred to the actual layer structure. Dynamic analysis was performed for the blade by using the finite element method. This study has been successfully applied to production of 20KW composite wind turbine blades.
