Abstract

Svrha ovog rada je usporediti rezultate analitičke i numeričke analize naprezanja za trup velikog putničkog aviona. Analitička metoda provedena je u programu Matlab za pojednostavljeni kružni i bubble presjek trupa, dok su model za numeričku analizu, i sama analiza izvršeni u programskim paketima SolidWorks, odnosno Abaqus/Standard i provedeni za kružni presjek. Opterećenja korištena u analizama čvrstoće su momenti savijanja prilikom usporedbe numeričke i analitičke metode, te moment uvijanja korišten na proračunu trupa s prozorima. Uz moment uvijanja kod trupa s prozorima dodana je i razlika tlakova između tlaka u kabini i tlaka atmosfere.

Abstract (english)

Aim of this Thesis is to compare the results of analytical and numerical analysis of stresses acting upon an airliner fuselage. Analytical approach was conducted using Matlab computing software and was applied on simplified circular and bubble fuselage cross sections, while the 3D model and the numerical analysis itself were made using SolidWorks and Abaqus software, respectively, and were carried out on circular fuselage cross section. Load types used in the strength analyses are bending moment for analytical and numerical method comparison, as well as torsion moment that was used in strength analysis of fuselage with windows. Together with torsion moment for fuselage with windows, resultant pressure from pressure difference between cabin and atmosphere was added.
