Modeling and analysis of wind turbine blade with advanced materials by simulation

摘要

Wind turbine efficiency depends up on one of the important parameters as the speed of the blade. for a lighter blade a small wind force is enough to rotate it, where as a heavy blade will require large and steady wind loads. To improve the wind turbine performance the blade material is being changed from epoxy glass to epoxy carbon. The modeling was done in Pro-E and the static and dynamic structural analysis is carried out by using ANSYS software. The blade was subjected to FEA studies to demonstrate its ability to withstand the extreme loading conditions as defined in the international offshore wind standard. The results confirmed the design to have acceptable performance with regard to total deformation, directional deformation, Equivalent stresses, Normal stresses and Shear stresses. We found better results for epoxy carbon material compared with epoxy glass that is discussed in this paper.
