Stress Analysis for Wing Attachment Brackets

Abstract

In this paper we describe how to design and analyze the brackets at various tensile loading conditions acting at Centre of Gravity point of fasteners. Material used for brackets and fasteners are Al alloy 7075-T6 and Ti-6Al-4V respectively. This is done to ensure structural stability. The equivalent stress is compared to yield strength of the material used. The design and analysis of the brackets and fasteners is carried out using CATIA V5 and ANSYS software. Finite element method is used for the stress analysis. Calculation of equivalent stress, shear stress and total deformation will be considered under this study. Finally, we've carried out modal analysis of brackets to know the right excitation conditions which may cause resonant response.
