Abstract

Zadatak ovog rada je provesti numerički proračun naprezanja i deformacija u postojećem konstrukcijskom rješenju za vertikalni spremnik za vino. Numerička analiza čvrstoće provedena je u računalnom paketu Abaqus koji je temeljen na metodi konačnih
elementa.
U uvodu je općenito opisan predmet analize (vertikalni spremnik za vino) i materijal od kojeg je predmet izrađen. U drugom poglavlju opisan je vertikalni spremnik za vino sa svojim dijelovima i sadržajem spremnika. U trećem poglavlju napravljen je analitički proračun svakog važnijeg dijela vertikalnog spremnika pomoću metoda linearne analize konstrukcija.
U četvrtom poglavlju opisana je metoda konačnih elemenata i računalni program Abaqus. Pojedini tipovi konačnih elemenata, korišteni u ovome radu, su detaljnije razrađeni. Za primjere u kojima je poznato analitičko rješenje, izvršena je provjera učinkovitosti pojedinih konačnih elemenata i odabir prikladnih tehnika modeliranja. Prikazan je također tok numeričkog proračuna zadanog vertikalnog spremnika. Razmatrana su tri modela, ljuskasti model, osnosimetrični model i trodimenzijski model. Prikazani su rezultati naprezanja i pomaka kao i usporedba tih rezultata s analitičkim rješenjem.

Abstract (english)

The task of this work is to conduct a control of a numerical analisys of stresses and strains in
the existing design for the vertical wine container. Numerical strength analysis was performed
in the computer package Abaqus which is based on the finite element method.
The introduction generally describes the object of analysis (vertical wine container) and the
material from which the object is made. The second chapter describes a vertical wine container
with its parts and the contents of the container. In the third chapter, an analytical calculation of
each important part of the vertical tank is made using the method of linear analysis of structures.
The fourth chapter describes the finite element method and the Abaqus computer program.
Certain types of finite elements, used in this work, are elaborated in more detail. For examples
where an analytical solution is known, the efficiency of individual finite elements is checked
and appropriate modeling techniques are selected. The flow of the numerical calculation of the
given vertical tank is also shown. Three models were considered, the shell model, the
axisymmetric model, and the three-dimensional model. The results of stresses and
displacements are presented as well as a comparison of these results with the analytical solution.
