| Popis: | U doktorskoj disertaciji obrađena je tema modeliranja i optimizacije polaganja podmorskih cjevovoda. Razmatran je model polaganja temeljen na nelinearnom elastičnom modelu grede uz elastične kontaktne interakcije s krutim strukturama valjkastih oslonaca i morskog dna. Osnovni model polaganja podmorskih cjevovoda te proširenja modela implementirani su i rješavani u softveru Abaqus za različite primjere polaganja cjevovoda. Formuliran je optimizacijski problem određivanja parametara polaganja, za koji je razvijena hibridna specijalizirana optimizacijska metoda temeljena na metodi optimizacije rojem čestica. Razvijeni optimizacijski postupak je testiran i analiziran na više različitih slučajeva polaganja podmorskih cjevovoda. The doctoral thesis deals with the topic of modeling and optimization of the submarine pipe laying. Considered laying model is based on a nonlinear elastic beam model with elastic contact interactions with rigid structures of roller supports and the seabed. The basic model of the submarine pipe laying and its extensions are implemented and solved in the Abaqus software for various pipe laying cases. The optimization problem is formulated to determine the parameters of pipe laying, for which a specialized hybrid optimization method is developed based on a particle swarm optimization method. Developed optimization method was tested and analyzed in several different cases of submarine pipe laying. |
