The present thesis work focuses on the analysis of some pressure vessels used in the hydraulic field. This work has been developed at the factory Euromisure Sas division of Wika Srl group. Euromisure is specialized in the production of Venturi Tubes, flow meter instruments, as flagship products; in addition, the factory has developed a department dedicated to production of pressure vessels, object of this work. The aim of the thesis is the development of structural analysis of these tanks in accordance with ASME VIII Division I, and the validation of these calculations through the software Sant’Ambrogio, specifically developed for the assessment of stresses for pressure vessels and heat exchangers. In parallel to analytical assessments, the tanks are modelled with CAD software, the Bill of Materials (BOM) are developed and the productive processes of the tanks are individuated. Once the stage by Euromisure was concluded, FEM structural analyses are developed in order to perform a structural integrity assessment of the pressure vessels following the Design by Analysis approach (DBA), in accordance with ASME suggestions. The software used is SolidWorks for the design of the geometry and Abaqus/CAE for the mesh creation and for finite element analysis.
Il presente lavoro di tesi verte sull’analisi di una gamma di serbatoi in pressioni utilizzati in ambito idraulico. Questo lavoro è stato sviluppato presso l’azienda Euromisure Sas facente parte del gruppo Wika Srl. L’azienda Euromisure è specializzata nella realizzazione di Tubi di Venturi, misuratori di portata, e oltre a questa produzione di punta ha sviluppato un reparto dedicato alla produzione dei serbatoi in pressione, oggetto di questo elaborato. Obiettivo di questa tesi è stato dunque la verifica strutturale di tali recipienti in pressione in accordo con il codice di calcolo ASME VIII Divisione I, e validata attraverso verifiche con il software Sant’Ambrogio, specificatamente sviluppato per la verifica dello stato di sforzo dei recipienti in pressione e scambiatori di calore. In parallelo a tali verifiche si sono sviluppati i modelli CAD e le distinte base, e sono stati identificati i processi produttivi necessari alla realizzazione dei vari prodotti. Terminato il periodo di tirocinio presso Euromisure sono state sviluppate delle analisi strutturali a elementi finiti per verificare lo stato di sforzo dei serbatoi seguendo l’approccio Design by Analysis (DBA) come consigliato anche dalla normativa ASME. I software utilizzati sono Solidworks per la preparazione della geometria e Abaqus/CAE per la creazione della mesh e per l’analisi agli elementi finiti.
