Abstract

The era of using wind energy to produce electricity was started since the late of 1800s.Wind turbine is a mechanism that used to convert kinetic energy of wind energy to mechanical energy through the blades and convert the mechanical energy of rotor to electricity through generator. However, the generator existed needs a high torque to start the rotation, hence higher wind speed needed to be provided in order to initiate the rotation. This project is carried out to analyze the stress distribution over the blade of Savonius type vertical axis wind turbine designed as the wind energy is applied to the blade. The designs of Savonius blade is generated through house of quality and morphological chart. There are 256 alternatives generated through morphological chart. 5 designs are chosen and compared using Pugh Method to determine the design used in this research. After the design is decided, the design is analyzed by applying different force distribution over the blade surface. The analysis is carried out using Inspire 2017 which the rotor is fixed in position using support and the analysis started after the material of parts are chosen. The stress distribution over the blade due to the force applied will be obtained. The results show that most of the stress is higher at the area near to the rotor. The design later is optimized through topology optimization. The result of optimization shows that the blade design already in optimum state which no parts has to been deducted from the design.
