20.500.12556/RUL-172014 Topološka optimizacija 3D tiskanega konzolnega stenskega nosilca za kolo Topological optimization of a 3D printed cantilevered wall bracket for a bicycle V zaključnem delu je predstavljena topološka optimizacija konzolnega stenskega nosilca za kolo z implementacijo 3D tiskanja. Najprej je podana teoretična osnova s poudarkom na metodah optimizacije ter uporabi 3D tiskalnikov. Opisana je priprava geometrije, izbira omejitev in ciljev optimizacije ter določitev ustreznih parametrov, kot so stopnja natančnosti, minimalna velikost elementa in število iteracij. V nadaljevanju so prikazani rezultati optimizacije ter primerjava obnašanja nosilca pri različnih materialih, pri čemer sta bila uporabljena PETG in PC. Sledi prilagoditev optimizirane geometrije zahtevam 3D tiska, kjer so bili opredeljeni ključni procesni parametri, kot so višina sloja, stopnja in oblika polnila, število obodov ter podporne strukture. Na osnovi teh nastavitev je bil izdelan prototip, ki je bil natisnjen in nato eksperimentalno preizkušen. Testiranje je zajemalo mehansko obremenitev s 24 kg mase in namestitev kolesa na nosilec. Rezultati so pokazali, da je mogoče s kombinacijo topološke optimizacije in aditivne proizvodnje izdelati funkcionalen nosilec, ki ustreza praktičnim zahtevam in potrjuje veljavnost uporabljenega pristopa. In the final thesis, the topological optimization of a 3D printed cantilever wall bracket for a bicycle is presented. First, the theoretical foundation is provided, with an emphasis on optimization methods and the use of 3D printers. The preparation of the geometry, selection of constraints and optimization objectives, and determination of appropriate parameters— such as the degree of accuracy, minimum element size, and number of iterations—are described. Subsequently, the optimization results are shown, along with a comparison of the bracket's behavior using different materials, where PETG and PC were employed. This is followed by the adaptation of the optimized geometry to the requirements of 3D printing, where key process parameters were defined, such as layer height, infill density and pattern, number of perimeters, and support structures. Based on these settings, a prototype was manufactured, which was printed and then experimentally tested. The testing involved mechanical loading with a 24 kg mass and mounting the bicycle on the bracket. The results demonstrated that it is possible to produce a functional bracket through the combination of topological optimization and additive manufacturing, which meets practical requirements and confirms the validity of the applied approach. topološka optimizacija 3D tisk konzolni nosilci računalniške simulacije materiali 3D tiska topological optimization 3D printing cantilever brackets computer simulations 3D printing materials true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2025-09-05 08:30:58 2025-09-05 08:31:05 2025-10-01 03:42:12 0000-00-00 00:00:00 2025 0 0 XI,35 f. 2025 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 624.07:004.925.84:519.6(043.2) 275498 248185091 43348.pdf 43348.pdf 1 B76DD9B33F6D1F65D61E8B98F4287343 ff636c65446e76b96b4578be4a92d313a7ed4fa4b65de7b4691bd999253da3df bfd35bd3-8a21-11f0-9328-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=215732 Fakulteta za strojništvo 0 0 0
