Abstract

U ovom radu provedena je optimizacija okvirnog rebra jednostavne brodske konstrukcije, pri čemu je za implementaciju optimizacijskog modela korišten programski jezik Python. Proračun odziva okvira proveden je metodom pomaka koja je jedna od metoda kojom se može dovoljno točno odrediti naprezanja u inicijalnoj fazi projektiranja konstrukcije. U okviru rada izrađen je matematički model proračuna odziva okvira primjenom objektno orijentiranog programiranja, u programskom jeziku Python. Za optimizaciju korištena je besplatna biblioteka SciPy u okviru koje su dostupne implementacije nekoliko različitih optimizacijskih metoda. U ovom radu, za optimizaciju okvirnog rebara jednostavne brodske konstrukcije, korištene su optimizacijske metode SLSQP i COBYLA.

Abstract (english)

The thesis presents the structural optimization of a simple ship structure web frame, where Python programming language was used for the implementation of the optimization model. The calculation of the response of a web frame was performed by the displacement method, which is one of the methods by which the stresses in the initial design phase of the structure can be determined with sufficient accuracy. Mathematical model of frame response calculation was developed using object-oriented programming, in Python programming language. For optimization, free SciPy library was used, within which implementations of several different optimization methods are available. In this paper, SLSQP and COBYLA optimization methods were used to optimize the web frame of a simple ship structure.
