Abstract

U radu je provedena numerička analiza proračuna sendvič konstrukcije krila hidroaviona čija maksimalna poletna masa iznosi 1400 kg. Na temelju dobivenog CAD modela hidroaviona izrađen je numerički model konstrukcije krila pri čemu je raspodjela opterećenja pri manevriranju proračunata u programskom paketu XFRL5.
Polinom koji opisuje raspodjelu tlaka po donjaci dobiven je u programskom paketu Matlab.
Numeričke analize provedene su primjenom Abaqus/Standard programa, a proračun čvrstoće proveden je temeljem graničnog i krajnjeg opterećenja iz V-n dijagrama.

Abstract (english)

In this master’s thesis numerical analysis of the sandwich structure of a seaplane wing with a maximum take-off weight of 1400 kg has been done. Based on the given CAD model of seaplane, a model of the wing structure was made, where the load distribution during maneuvering was calculated in the XFLR5 softwer package.
A polynomial describing pressure distribution of the wing lower surface was obtained in Matlab softwer package.
Numerical analyses were performed using the Abaqus/Standard program, and the strength analysis was performed based on ultimate and final loads from the V-n diagram.
