The Influence of Corrosion and Temperature Variation on the Minimum Safety Factor of a 3D Hexagonal Toroid with Regular Hexagonal Cross-Section Used in Manufacturing of LPG Storage Tanks
Journal Title: HIDRAULICA - Year 2018, Vol 0, Issue 3
Abstract
In this paper we investigate the minimum safety factor (SF) values of a three-dimensional (3D) hexagonal toroid with regular hexagonal cross-section used in manufacturing of LPG storage tanks from the automotive industry. A design strategy was proposed to determine SF according to manufacturing objectives due to the influence of corrosion and temperature variation. Numerical simulations were carried out to determine the surfaces or curves for which the SF has the minimum values and the corresponding variation laws were computed by polynomial interpolation. We coupled numerical simulations of a 3D model (done in the AutoCAD Autodesk 2017 software, which was imported for analysis to SolidWorks 2017 software) with numerical limit analysis to calculate confidence intervals of the safety factor. The results of analyzed cases advocate the need for implementing a reliability improvement program of toroidal LPG fuel tanks.
