SolidWorks used for the process of optimization of supporting structure of a pressure vessel

Abstract

According to the new regulations of the European Community (Directive 97/23/EC, design and manufacture of the pressure vessels (PV) shall be in accordance with legal and technical regulations stating the application of harmonized standards to be optional for a manufacturer of the equipment. Increased responsibility of the manufacturers gives more freedom in selection of the methods, design, calculation and optimization in order to provide safety. In this paper, using a liquid CO2-containing vessel as an example, a survey of the process of optimization of a supporting structure has been presented. For parametric design, construction and calculation the SolidWorks programme has been used, taking into consideration the regulations and standards in effect, and in accordance with new and general approach to pressure equipment (Pressure Equipment Directive – PED) relating to structural integrity, i.e. fundamental requirements in terms of safety, calculation, design and testing of strength.
