Nelinearne metode redukcije modelov v dinamiki podstruktur : magistrsko delo magistrskega študijskega programa II. stopnje Strojništvo

Pogačar, Miha, strojnik

Dinamska analiza kompleksnih struktur je računsko zahtevna, zato se poslužujemo delitve strukture na več podstruktur. Vsako izmed podstruktur analiziramo ločeno in z metodami redukcije zmanjšamo ... število njenih prostostnih stopenj, nato pa podstrukture sklopimo v celoto, kar omogoča hitrejšo analizo. V prvem delu magistrske naloge je predstavljena geometrijsko linearna formulacija končnega elementa ter Craig-Bamptonova in Rubinova metoda redukcije modelov. V drugem delu magistrske naloge je formulacija končnega elementa razširjena z nelinearno zvezo med pomiki in deformacijami, kar predstavlja geometrijsko nelinearnost. Zaradi nelinearnosti sistema je potrebna tudi nadgradnja redukcijske metode. Dinamski odziv smo izračunali z uporabo analitičnih enačb, analizo celotne strukture z metodo končnih elementov in uporabo redukcijskih metod. V izbranem frekvenčnem območju smo pokazali dobro ujemanje.
