20.500.12556/DKUM-88557 Modeliranje in izdelava dušilca zvoka za strelno orožje Modeling and manufacturing sound suppressor for firearms Cilj magistrske naloge je bil izdelati dušilec zvoka za strelno orožje modela M70 s kalibrom 7,62 × 39 mm. Prvotno je bilo treba analizirati in proučiti, do sedaj že znane študije in pregledati že izdelane dušilce. Na podlagi teh smo v programskem okolju SolidWorks oblikovali štiri različne oblike ekspanzijskih komor, na katerih smo na to v istem programskem okolju izvedli analizo zračnega tlaka in akustičnih moči. Po končani analizi smo komore in ostale potrebne sklope dušilca izvozili v obliki STEP formata in dušilec fizično izdelali na CNC obdelovalnem stroju. Za izdelane dušilce smo izvedli tudi meritve jakosti zvoka na terenu. Na koncu smo določili najprimernejši dušilec za obravnavano strelno orožje. As part of the master's thesis, the goal was to produce a silencer for firearms model M70, in caliber 7.62 × 39 mm. Originally, it was necessary to analyze and study, already known studies and review of already manufactured silencers. Based on these, we designed four different forms of expansion chambers in the SolidWorks software environment, on which we performed a pressure and acoustic power analysis in the same software environment. Then, we exported the chambers and other necessary parts of the muffler in the STEP format and physically produced the muffler on a CNC machining machine. We also carried out sound measurements on the produced mufflers in the field. In the end, we determined the most suitable suppressor for our firearm in question. strelno orožje dušilec zvoka hrup modeliranje izdelava SolidWorks firearms silencer noise modelling manufacturing SolidWorks true true false Slovenski jezik Angleški jezik Magistrsko delo/naloga 2024-05-10 13:55:20 2024-05-30 09:30:06 2024-05-31 03:48:44 0000-00-00 00:00:00 2024 0 Maribor 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 MAG_Satan_Luka_2024.pdf MAG_Satan_Luka_2024.pdf 1 0F22F65C31757DFB63FC3EFD4A44E1EE 5c2c51742a8805ebf44544397c7337863bbe64020479c94d1b62dc198eff9f2f 791dfcf1-1e46-11ef-9a97-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=179939 Fakulteta za strojništvo 0 0 0
