Comparison of the numerical and analytical metallic wing structure stress analyses

Cilj ovog rada je usporediti numeričku i analitičku metodu proračuna čvrstoće metalne konstrukcije krila. Kroz rad je dan pregled drugih analitičkih metoda te detaljan opis analitičke metode koja je odabrana u ovom radu. Opisan je proces izrade modela krila zrakoplova u programu SolidWorks kao priprema modela za numeričku analizu. Razrađen je postupak prebacivanja 3D modela u program Abaqus/Standard gdje je provedena numerička analiza. Dana je potpuna analiza analitičkih i numeričkih rješenja za odabrane konstrukcije krila u kojima su varirane geometrijske karakteristike i načini izvedbe konstrukcije krila. Za konstrukciju krila su korišteni standardni metalni materijali u zrakoplovnom inženjerstvu kao i uobičajeni konstruktivni elementi. U zadnjem poglavlju rada iznesen je zaključak.The aim of this thesis is to compare the numerical and analytical methods of strength prediction of the metallic wing structure. The paper provides an overview of other analytical methods and a detailed description of the analytical method chosen in this thesis. The process of creating a model of an aircraft wing in the SolidWorks program is described as a preparation of the model for numerical analysis. The process of transferring the 3D model to the Abaqus/Standard program was conducted, where the numerical analysis was performed. A complete analysis of the analytical and numerical solutions for selected wing structures in which the geometric characteristics and structural layout of the wing are varied is given. Standard metallic materials in aeronautical engineering as well as common structural elements were used for the construction of the wings. In the last chapter of the paper, the conclusion is presented
