Dinamska strukturna analiza cevne Kaplanove vodne turbine : magistrsko delo magistrskega študijskega programa II. stopnje StrojništvoHafner, GalV projektiranju vodnih turbin je potrebno le-te tudi dinamsko analizirati, saj zaradi visokih pobežnih hitrosti lahko pride do katastrofalnih posledic. Velikokrat je dinamska analiza zahtevana kot ... končna projektna dokumentacija pri izdelavi vodnih turbin. V magistrski nalogi je bila izvedena dinamska analiza horizontalne cevne Kaplanove turbine tipa S. Izračunani so bili maksimalni povesi gredi ter povesi gredi pod gonilnikom z ozirom na zračnost gonilnih lopat. Preko maksimalnih povesov gredi smo izračunali lastne upogibne frekvence pogonske gredi z uporabo Dunkerleyeve formule. Izračunali smo torzijske lastne frekvence, kjer smo v prvem primeru upoštevali samo gred, v drugem primeru pa smo upoštevali še zobniški prenos ter vztrajnost generatorja. Izračuni so bili narejeni teoretično, v programskem paketu Ansys ter v programskem paketu XLRotor. Dobljeni rezultati med posameznimi modeli so primerljivi ter ustrezajo zahtevam naročnika.Type of material - master's thesis ; adult, seriousPublication and manufacture - Ljubljana : [G.
