Wind Mill Shaft Optimization Based on layer Orientation Angles using Composite Materials

Abstract

This paper presents an application of Finite Element Analysis (FEA) for strength improvement of wind mill shaft. Also provides fundamental knowledge of transmission shaft analysis using composite material. The existing shaft is modelled using CATIA and analyzed using ANSYS 16.0. The results for stresses generated are shear stress 68.298MPa, von-mises stress 119.2MPa and deformation is 3.3905mm. First optimization is done based on fibre orientation angles of composite material. Further alternate material selection is done through study and optimization analysis is done for the same. Carbon epoxy-UD selected as material and gives final stresses as 22.974MPa and deformation is 1.255mm. The torsion deflections were obtained experimentally. The results of experimental study and FEA results are found same as infinite life.
