Conceptual Design and Structure Analysis of Savonius Vertical Axis Wind Turbine under Low Wind Speed
Keywords:savonius blade, low wind speed, pugh method, topology optimization
This research aims to investigate the stress distribution of Savonius type vertical axis wind turbine subjected to different wind speeds and different penetration positions. This research work involves applying 12 different wind speeds to the design generated from Pugh Method. The wind energies were applied to two positions, which were the edge of blade and uniformly distributed throughout the surface of the blade. SolidWorks 2015 software was used to draw the design of Savonius type vertical axis wind turbine. The drawing was imported to Inspire 2017 for analysis. The analysis is conducted to determine the stress distribution of the blade as wind energy applied to the blade. The results showed that the stress was higher in the area near to the rotor. The results also showed that the maximum displacement, maximum tension/compression stress, maximum shear stress, maximum von Mises stress, and maximum major principal stress of the blade increased as the force or pressure applied increased.
