Finite Element Analysis and Structural Optimization of the Box on the ANSYS Workbench

Abstract

Aiming at the phenomenon that box parts had large deformation and highly centralized stress in working process, CAE technology based on platform ANSYS Workbench (AWE) had been used on the box for finite element analysing and structure optimizing.Based on illuminating the structure of AWE system, the total deformation, equivalent stress and safety factor of box under static water pressure were analysed and the stress distribution was gained. Based on this, the optimization methods of welding angle angle irons and changing the installation position of supports had been proposed, and the box after optimization had been analysed. The results show that the box had high safety factor,uniform stress, small deformation, superior performance after optimization and it also can fully meet the operating requirement.
