Modal and Structural Analysis of Polymer Composite Vawt Savonius Blade using ANSYS Workbench

Any wind turbines efficiency mainly depends on the material of the wind turbine, shape of the turbine blade, speed of the wind and blade angle. Here material plays an important role in design of wind turbine blade. Wind turbine blades are mostly made of more density materials such as steel and aluminum. This is main cause for huge weight and it has less fatigue strength and more corrosion rate. The high density materials can be replaced by composite materials such as GFRP to reduce the weight of the turbine, to improve fatigue strength and corrosion resistance and to make them more efficient. Here Glass Fiber Reinforced Polymer (GFRP) material was used to model wind turbine of one meter height and one meter diameter with four different arc radiuses. Modeling software Solid Works is used to model wind blade of four different shapes with GFRP material and static structural analysis and modal analysis of the GFRP wind blade is done by using Ansys Workbench analysis Software.
