20.500.12556/RUL-165361 Zasnova zadnjega avtomobilskega spojlerja Design of an automotive rear spoiler V sklopu zaključnega dela smo želeli zasnovati zadnji spojler za specifični osebni avtomobil s poudarkom na performancah. Že obstoječo izvedbo spojlerja smo računsko in eksperimentalno analizirali, ter na podlagi ugotovitev določili novo obliko, ki je bolj učinkovita. Teoretični model smo 3D natisnili v pomanjšanem merilu, ter analizirali njegovo funkcionalnost v vetrovniku. Izvedli smo tudi simulacije s pomočjo računalniške dinamike fluidov. Izdelek smo primerjali s tovarniškim spojlerjem in poprodajnim prostostoječim spojlerjem. Na podlagi rezultatov smo izdelali prototip v polni velikosti, ki je primeren za praktično uporabo. As part of this thesis, we wanted to design an automotive rear spoiler for a specific vehicle, with an emphasis on performance. We analysed the shape of the vehicle's existing spoilerboth computationally and experimentally, and based on the findings, determined a more efficient design. The new design was 3D printed on a smaller scale, after which we analyzed its functionality in a wind tunnel. We also carried out simulations through computational fluid dynamics. We compared our product to the aforementioned existing spoiler as well as an aftermarket free-standing wing. A full-size prototype, suitable for practical use was made, based on the results of testing. avtomobilski spojler aeroprofil aerodinamična obtežitev aerodinamika vozil vetrovnik simulacija zračnega toka automotive rear spoiler airfoil downforce vehicle aerodynamics wind tunnel airflow simulation true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2024-12-04 08:30:52 2024-12-04 08:30:54 2025-01-22 12:14:47 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 0000-00-00 629.3.025.3:629.331(043.2) 270348 223470851 38354.pdf 38354.pdf 1 664749EEBD2F9FFEA82A8AB493E5D427 91f146108185fe3e923d9a42dfd5be5cd722ab4e534d8e44cb8f1a13ee66d046 40c162f1-b211-11ef-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=196491 Fakulteta za strojništvo 0 0 0
