20.500.12556/RUL-164709 Razvoj rezalnika drv Development of a wood cutter Na domači kmetiji se ukvarjamo s pripravo in prodajo drv. Celoten postopek je dolg in vsebuje veliko ročnega dela. Zato smo se odločili optimizirati postopek žaganja lesnih sortimentov na primerno dolžino za kurjenje. Izvedli smo analizo trga in na podlagi te analize naredili konstrukcijski zahtevek. V delu smo pregledali literaturo o izračunu rezalnih sil pri odrezovanju. Naredili smo morfološko matriko in tvorili tri koncepte. Koncepte smo ocenili in najboljšemu izdelali 3D model. Izračunali smo rezalno silo na podlagi Kienzlejeve enačbe za les. Izbrali smo hidravlične komponente na osnovi zahtevanih obratovalnih pogojev. S pomočjo metode končnih elementov smo analizirali kritični del in zvar rezalnika. Na koncu smo naredili detajlno stroškovno analizo. On our family farm, we are involved in the preparation and sale of firewood. The entire process is lengthy and requires a lot of manual labor. Therefore, we decided to optimize the process of sawing wood assortments to a suitable length for burning. We conducted a market analysis and developed a design specification based on this analysis. In the thesis, we reviewed the literature on the calculation of cutting forces during cutting. We created a morphological matrix and developed three concepts. We evaluated the concepts and created a 3D model for the best one. We calculated the cutting force based on the Kienzle equation for wood. We selected hydraulic components based on the required operating conditions. Using the finite element method, we analyzed the critical part and weld of the cutter. Finally, we conducted a detailed cost analysis. rezalnik kienzlejeva enačba drva koncipiranje EUROCODE 3-1.9 cutter kienzle equation firewood conceptualization EUROCODE 3-1.9 true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2024-11-08 08:30:25 2024-11-08 08:30:33 2025-01-22 14:08:21 0000-00-00 00:00:00 2024 0 0 XX, 50 str. 2024 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 631.363.2:621.8(043.2) 270117 223150595 38337.pdf 38337.pdf 1 5971FD57BF7ABF7A64599CFBFFA27CDC 7ac1810f69079c4984c66468914fa685b6b64d27262ff8b59da0e6873216958a fd31eb25-9da2-11ef-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=195332 38338.pdf 38338.pdf 1 0EB5D05532A51E2823B5B9A185C35358 0ba056fb7f2a80544feb4cd15cbf393b5d0c1768b5921813488851daedff36ed fd33b656-9da2-11ef-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=195333 38339.pdf 38339.pdf 1 1F58C200C8BE04099F3EAD9AC584EE0A b028a410540af4ca42b75307181b1f35b64438633eee96bf45ec322348724f5e fd340665-9da2-11ef-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=195334 Fakulteta za strojništvo 0 0 0
