Trdnostna analiza linijske konstrukcije z uporabo superelementov

Žužek, Jan (author), Halilovič, Miroslav (mentor)

Zaključna naloga obravnava trdnostno analizo linijske konstrukcije z uporabo superelementov. Analizirana in razrešena je enostavna konstrukcija, sestavljena iz linijskih nosilcev in palic. Sledi izpeljava enačbe superelementa ter ponovna razrešitev enostavnega primera s pomočjo le-tega. Potem je s pomočjo superelementov, sestavljenih v sestav, razrešena realistična konstrukcija, sestavljena iz več ponavljajočih se konstrukcij. Na koncu je superelement rekonstruiran, izračunane pa so tudi napetosti v elementih znotraj superelementa. Rešitev je preverjena s programskim paketom ABAQUS.

• Title: Strength analysis of beam element structures with use of superelements

Abstract

This thesis discusses strength analysis of beam element structures with use of superelements. It analyses and solves simple structure made of bar and beam elements. The derivation of superelement equation in explained followed by a solution of a simple example with its use. With a help of superelements, assembled into the assembly, a realistic structure consisting of several repetitive structures is resolved. In the end the superelement is reconstructed and the stresses in the elements within the superelement are calculated. The solution is verified with ABAQUS software package.
