ANALYSIS OF SAVONIUS TURBINE BLADES WITH ANGLE VARIATIONS USING FEA SIMULATION IN SOLIDWORKS

Abstract

The global energy crisis and the need for renewable energy sources have driven the development of wind turbine technology, one of which is the Savonius type turbine. This study aims to analyze the effect of blade angle variations on the structural strength of the Savonius turbine using the Finite Element Analysis (FEA) method in SolidWorks software. Blade models with angles of 0°, 5°, and 10° were analyzed using ABS (Acrylonitrile Butadiene Styrene) material, with evaluation parameters in the form of maximum stress, total deformation, and strain. The simulation results show that the 10° blade configuration produces the most optimal structural performance, with a maximum stress of 61.43 MPa, a maximum displacement of 9 mm, and a maximum strain of 0.002. Compared to the 0° and 5° blades, this configuration shows a more even distribution of stress and strain, thus minimizing load concentration at critical points. Although all configurations produce stresses exceeding the elastic limit of ABS material (±45 MPa), the 10° blade is still recommended as the best design alternative from the aspect of load distribution and structural integrity, with the note that materials with higher mechanical strength are required for practical applications.
