Abstract
In this paper structural analysis and topological optimization of bolted joint Flange fitting using Super Austenitic Stainless Steel have been studied in order to achieve effective structural design. Flange fittings are used to connect pipes, pumps, valves, shafts and supporting structures where the connection between two flanges is very prone to corrosion. The failure of one of these connections could cause severe damage. In this study FEA analysis has been performed on flange fitting using Super Austenitic Stainless Steel. The current work has been initiated from designing a 3D model of Flange Fitting in Auto-Cad which then imported to Ansys Design Modeller for structural, modal analysis and topological optimization. Static structural analysis is usually done for finding overall strength of the design. Equivalent stresses (Von Mises), Total deformations and modal analysis on Flange fitting of Alloy steel and Super Austenitic Stainless Steel (UNS S31254) have been evaluated for checking the stability of the flange fitting. The aim of this study is to reduce the weight of the flange fitting using mass reduction as a constraint in topological optimization. A comparative result between optimized design and original design has been described within this study.
