20.500.12556/RUL-166004 Interakcija objektov z mikrostrukturirano površino magnetoaktivnega elastomera The interaction of objects with microstructured surface of a magnetoactive elastomer V magistrskem delu obravnavamo mikrostrukturirano površino magnetoaktivnega elastomera in njeno interakcijo z različnimi objekti v nehomogenem magnetnem polju. Za natančno analizo smo uporabili visokohitrostno kamero v kombinaciji z napredno programsko opremo, ki omogoča enostavno sledenje hitro premikajočim se lamelam. Osredotočamo se na proučevanje nehomogenega kvadrupolnega magnetnega polja ter analiziramo odzive posamezne lamele in skupine lamel v takem polju. Prav tako preučujemo hitrost odziva lamel, širjenje vala lamel in nehomogeno dviganje lamel. Poleg tega raziskujemo trke lamel s kroglicami, njihovo gibanje, koeficient restitucije ter spremembe vrtilne količine, pri čemer dobljene rezultate primerjamo z različnimi teoretičnimi modeli. Poseben poudarek namenjamo predstavitvi, zakaj so tako oblikovani magnetoaktivni elastomeri še posebej primerni za uporabo v mikrofluidičnih napravah tipa lab-on-a-chip in kot samočistilne površine. V zaključku podamo tudi nekaj predlogov za nadaljnje raziskave na tem področju. In this thesis, we discuss the microstructured surface of a magnetoactive elastomer and its interaction with different objects in an inhomogeneous magnetic field. For a detailed analysis, we have used a high-speed camera in combination with advanced software that allows easy tracking of fast-moving lamellae. We focus on the study of inhomogeneous quadrupole magnetic fields and analyse the responses of individual lamellae and groups of lamellae in such fields. We also study the response velocity of the lamellae, the propagation of the lamellae wave and the inhomogeneous lifting of the lamellae. In addition, we investigate the lamellae-ball collisions, their motion, the restitution coefficient and the variations of the angular momentum, comparing the results obtained with different theoretical models. Special emphasis is given to presenting why such shaped magnetoactive elastomers are particularly suitable for use in lab-on-a-chip devices and self-cleaning surfaces. Finally, we make some suggestions for further research in this area. magnetoaktiven elastomer MAE mikrostrukturiranje lamele trki nehomogeno magnetno polje restitucijski koeficient vrtilna količina magnetoactive elastomer MAE microstructuring lamellae collisions inhomogeneous magnetic field restitution coeficient rotational quantity true false false Slovenski jezik Angleški jezik Magistrsko delo/naloga 2024-12-17 10:33:21 2024-12-17 10:33:27 2025-01-10 10:53:52 0000-00-00 00:00:00 2024 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 149905 219039747 16587.pdf 16587.pdf 1 65DC5DA89D3F76F0BE70237B077B31CD 1ca27e8ae17cb071dac06671d1be69e3fb2ff407c40eec565a6119fa7b953cd8 70482ece-bc59-11ef-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=197361 Fakulteta za matematiko in fiziko 0 0 0
