20.500.12556/RUL-179941 Določanje mehanskih lastnosti lameliranih statorskih paketov z uporabo meritev lastnih frekvenc Determination of mechanical properties of laminated stator packs using natural frequency measurements Problem nepoznavanja togostnih materialnih lastnosti vodi v dejstvo, da potrebujemo dejanske meritve, saj ocene preko simulacij ni mogoče izvesti zaradi pomanjkanja podatkov. Problem smo želeli rešiti, zato smo izmerili lastne frekvence, preko katerih smo s postopkom optimizacije z odzivno površino pridobili želene podatke. Uporabili smo linearno elastični model za popis kompozitnega materiala, katerega namen je bil hitrost in lahka uporaba. Dokazali smo tudi, da so meritve mobilnih telefonov, kar se tiče lastnih frekvenc, enakovredne tistim, ki so narejene s profesionalno opremo. The problem of unknown stiffness material properties leads to the necessity of performing actual measurements, as estimations through simulations cannot be conducted due to a lack of data. To solve this problem, the natural frequencies were measured and, through a response surface optimization process, the desired material parameters were obtained. A linear elastic model was applied in order to describe the composite material, aiming for speed and ease of use. It was demonstrated that natural frequency measurements conducted using mobile phones are equivalent to those obtained with professional equipment. prečno izotropne materialne lastnosti lastna frekvenca optimizacija odzivna površina mobilni telefoni primerjava transversely isotropic material properties natural frequency optimization response surface mobile phones comparison true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2026-02-27 08:30:54 2026-02-27 08:30:57 2026-03-02 09:53:04 0000-00-00 00:00:00 2026 0 0 XX, 44 str. 2026 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 539.3/.4:621.3.043.2:534.63(043.2) 283276 270056195 46582.pdf 46582.pdf 1 C67C36A15D524C2544F43E65CA96B604 9fa85272f33badbbd06772ea7fd43ed1391dbce72229ad0ef42577b230d0a063 ee52bc1f-13ad-11f1-a1ba-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=228881 Fakulteta za strojništvo 0 0 0
