Abstract

Predmet ovog rada je numerička analiza naprezanja krila s različitim kutovima strijele krila u programskom paketu Abaqus/Standard.
Konstrukcijski elementi krila te geometrija i dimenzije promatranog krila opisani su u drugom i trećem poglavlju.
U četvrtom poglavlju prikazana su svojstva materijala različitih konstrukcijskih elemenata, opisani su postupci izrade mreže konačnih elemenata te su prikazana korištena opterećenja i rubni uvjeti.
U petom poglavlju prikazana su naprezanja i progibi koja se javljaju u torzijskoj kutiji te su grafički prikazana naprezanja u gornjim i donjim pojasevima prednje, stražnje i pomoćne ramenjače.
Zaključak se nalazi u šestom poglavlju.

Abstract (english)

The content of this thesis is numerical stress analysis of wing at various sweep angles using Abaqus/Standard software package.
Structural elements, wing dimensions and geometry of the analysed wing are described in the second and third chapters.
In the fourth chapter, material properties of various structural elements are shown, the process of finite element mesh generation is described and the applied loads and boundary conditions are shown.
The fifth chapter shows stress and deflection that occur in the wing box as well as graphs which show the stress states in the lower and higher spar caps of front, rear and auxilary spar.
The conclusion is given in the sixth chapter.
