20.500.12556/RUL-171295 Vpliv temperature na vibracijsko utrujanje 3D-natisnjenih PEEK struktur The effect of temperature on the vibration fatigue of 3D-printed PEEK structures Magistrsko delo obravnava vpliv temperature na dobo trajanja pri vibracijskem utrujanju 3D-natisnjenih struktur, izdelanih iz polieter eter ketona (PEEK) s postopkom ciljnega nalaganja. Najprej je bil zasnovan vzorec, sledil je 3D-tisk vzorcev in na koncu eksperiment, izveden na elektrodinamskem stresalniku s temperaturno komoro. V nadaljevanju je bila na podlagi eksperimenta izvedena numerična ocena dobe trajanja s pomočjo Dirlikove metode in optimizacije parametrov Basquinove enačbe za različne temperature okolice. Rezultati so pokazali boljšo odpornost PEEK-a na utrujanje pri nižjih temperaturah. The master's thesis investigates the effect of temperature on the fatigue life of 3D-printed structures made from polyether ether ketone (PEEK) under vibrational loading. The process began with the design of the specimen, followed by 3D-printing of the samples, and finally experimental testing performed on an electrodynamic shaker equipped with a temperature chamber. Based on the experimental data, a numerical fatigue life estimation was carried out using Dirlik's method and optimization of the parameters in Basquin's equation for different ambient temperatures. The results indicated improved fatigue resistance of PEEK at lower temperatures. vibracijsko utrujanje 3D-tisk polimerov strukturna dinamika kinematsko vzbujanje temperaturni vpliv na utrujanje PEEK vibration fatigue 3D-printing of polymers structural dynamics base excitation temperature effect on fatigue PEEK true false false Slovenski jezik Angleški jezik Magistrsko delo/naloga 2025-08-22 08:30:24 2025-08-22 08:30:26 2025-08-28 03:37:55 0000-00-00 00:00:00 2025 0 0 XXII, 58 str. 2025 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 620.178.5:536.74:678.744.4(043.2) 274527 246533379 42895.pdf 42895.pdf 1 1E6674839398F9E4362F7CAB66016780 3fca810b0b27eadad885ba8d000f76e993358a617ac6836fb29033fd7cb242af 62de0359-7f21-11f0-9328-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=214519 Fakulteta za strojništvo 0 0 0
