20.500.12556/ReVIS-10757 NAČRTOVANJE IN RAZVOJ MERILNIKA PRETOKA VODE Z ZASTOJNIM DISKOM DESIGN AND DEVELOPMENT OF A WATER TARGET FLOW METER Magistrsko delo obravnava načrtovanje in razvoj merilnika pretoka vode z zastojnim diskom, namenjenega merjenju prostorninskega pretoka vode v merilnem razponu od 0,5 do 20 m3/h. V delu so uvodoma predstavljena teoretična in fizikalna izhodišča delovanja merilnika pretoka ter konstrukcijska zasnova prototipnega modela, ki bo prvotno narejen s tehnologijo 3D-tiskanja, v nadaljevanju pa bo narejen tudi kot učni pripomoček iz nerjavečega jekla. Imenski premer pretočne cevi, v katero bo vgrajen merilnik, je DN50. Raziskava vključuje pregled obstoječe literature in dosegljivih analiz merilnikov pretoka z zastojnim diskom, ki so že na voljo na trgu. Nato sledi pregled teoretičnih osnov mehanike tekočin in trdnin ter popis merjenja mehanskih sil na konzolno vpetem nosilcu. V nadaljevanju je predstavljen konstrukcijsko-razvojni proces in postopek izdelave tehnične dokumentacije prototipnega merilnika. S pomočjo numeričnih simulacij in izračunov, izvedenih s programsko opremo ANSYS, je bila razvita kompaktna konstrukcija merilnika pretoka, ki bo potencialno ustrezna za praktično uporabo. This master's thesis addresses the design and development of a water target flow meter, intended for measuring volumetric water flow in the measauring range of 0.5 to 20 m3/h. The thesis initially presents the theoretical and physical principles of operation of the flow meter and the design of the prototype model, which will initially be made using 3D printing technology, and subsequently as a teaching aid made of stainless steel. The nominal diameter of the flow pipe into which the meter will be installed is DN50. The research includes a review of existing literature and avaliable analysis of current target flow meters available on the market. This is followed by a review of the theoretical foundations of fluid and solid mechanics, and a description of the measurement of mechanical forces on a cantilever beam. The design and development process and the procedure for creating technical documentation of the prototype meter are then presented. Using numerical simulations and calculations performed with ANSYS software, a compact flow meter design was developed that is potentially suitable for practical use. merilnik pretoka vode zastojni disk 3d-tiskanje optična vlakna konzolni nosilec simulacije water flow meter target 3D printing optical fiber cantilever beam simulation true false false Slovenski jezik Angleški jezik Magistrsko delo/naloga 2024-09-07 18:36:46 2024-09-07 18:36:47 2024-10-09 13:15:15 0000-00-00 00:00:00 2024 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1970-01-01 4826 210841859 MAG_Pugelj_Denis_2024.pdf MAG_Pugelj_Denis_2024.pdf 1 035413AACAF5686287C23984DD2B5829 d29274a861689e6247de899fd8b40323af2d019f527daf56b67fa7547dbfb76e 6011146f-6d37-11ef-9ebd-001a4af901a5 https://revis.openscience.si/Dokument.php?lang=slv&id=12271 Univerza v Novem mestu - Fakulteta za strojništvo 0 0 0
