20.500.12556/RUL-191239 Izdelava in uporaba 3D-natisnjenih termičnih elementov z bakreno žico pri dinamskem odzivu nosilca Fabrication and application of 3D-printed thermal elements with copper wire in the dynamic response of a beam V diplomskem delu smo razvili postopek izdelave natisnjenega grelnega elementa z integrirano kontinuirano bakreno žico in raziskali vpliv lokalnega segrevanja na dinamski odziv sestavljenega nosilca. Izziv sočasnega dovajanja žice in polimera smo obravnavali s preizkušanjem različnih rešitev ter prilagoditvijo tiskalne glave in postopka izdelave. Delovanje izdelanega elementa smo preverili s toplotno karakterizacijo. Nato smo z udarnim vzbujanjem izmerili akceleranco nosilca in z eksperimentalno modalno analizo ovrednotili njegov odziv pri različnih referenčnih temperaturnih stanjih. Ugotovili smo, da so pri višjih referenčnih temperaturah lastne frekvence nižje, ocenjeno dušenje pa večje. Ker temperature med modalnimi meritvami nismo neposredno spremljali, ugotovitve omejujemo na referenčna temperaturna stanja. Razviti postopek predstavlja izhodišče za vključevanje drugih kontinuiranih funkcionalnih materialov v natisnjene polimerne strukture. In this thesis, we developed a process for producing a 3D-printed heating element with an embedded continuous copper wire and investigated the effect of local heating on the dynamic response of an assembled beam. We addressed the challenge of feeding the wire and polymer simultaneously by testing different solutions and adapting the print head and manufacturing process. We verified the element’s performance through thermal characterization. We then measured the beam’s accelerance under impact excitation and evaluated its response at different reference temperature conditions using experimental modal analysis. We found that higher reference temperatures were associated with lower natural frequencies and higher estimated damping ratios. Because we did not monitor temperature directly during the modal measurements, we limit our conclusions to the reference temperature conditions. The developed process provides a basis for incorporating other continuous functional materials into printed polymer structures. aditivne tehnologije ciljno nalaganje grelni elementi strukturna dinamika aktivna kontrola lastne dinamike additive manufacturing fused filament fabrication with continuous wire heating elements structural dynamics active control of resonance frequency true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2026-11-12 15:42:00 2026-11-12 15:42:05 2026-11-13 04:02:00 0000-00-00 00:00:00 2026 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1970-01-01 296878 51301.pdf 51301.pdf 1 10C022BB7611C032DB76F801819E1065 5671b4b7ea87e21a5c8b91a2b4a8d446c09e7bd8f3e51cd17c4ada03675a80cf 1dc2688c-dea7-11f1-aea2-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=253253 Fakulteta za strojništvo 0 0 0
