Examination of Structural and Dynamic Properties for Vertical Axis Wind Turbine Blade Made of Stainless Steel using Ansys

Abstract

This paper studies the potential for installing savonius type Vertical Axis Wind Turbine systems with the goal of maximizing the efficiency and reducing the cost. The wind turbine efficiency depends on the material of the blade, angle of the blade and shape of the blade. So material of the wind turbine blade plays an important role in the design of wind turbine. In this paper, Stainless Steel is used to design savonius wind blades of 1 m height and 0.5 m chord length with 4 different arc radii. For this purpose, CAD modeling software Solid Works is used to model savonius wind blade and static structural and modal analysis of the Stainless Steel blade is done by using ANSYS Workbench software. Static structural analysis is used to determine stress, strain, deformation and displacement under static loading condition. The response of structure for dynamic loading is determined by modal analysis. It is used to determine the natural frequency and mode shape of vibration of any structure. This wind turbine is suitable to install in small houses in urban areas.
