20.500.12556/RUL-171550 Numerična analiza varnostnega loka vozila z uporabo metode končnih elementov Numerical analysis of a vehicle roll bar structure using the finite element method Diplomska naloga obravnava zasnovo in mehansko analizo zaščitnega loka za vozilo Mazda MX-5. V programskem okolju Abaqus sta bila analizirana dva modela, prvi z enojnim indrugi z dvojnim lokom, ob upoštevanju vertikalnih, bočnih ter vzdolžnih obremenitev. Ugotovili smo, da sta vertikalni in bočni pomik pri obeh modelih podobna, medtem ko se je enojni lok zaradi svoje geometrije pri vzdolžni obremenitvi deformiral prekomerno. Rezultat celotnega dela je prikaz mehanskega odziva konstrukcije, njenih pomikov ter napetosti. The diploma thesis addresses the design and mechanical analysis of a roll bar for a Mazda MX-5 vehicle. In the Abaqus environment, two models were analyzed, one with a single hoop and the other with a double hoop design, considering vertical, lateral, and longitudinal loads. It was found that the vertical and lateral displacements were similar for both models, while the single hoop exhibited excessive deformation under longitudinal loading due to its geometry. The outcome of the study presents the mechanical response of the structure, including its displacements and stresses. varnostne strukture metoda končnih elementov deformacije Abaqus numerična analiza avtomobili safety structures finite element method deformation Abaqus numerical analysis cars true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2025-08-28 08:30:57 2025-08-28 08:30:59 2025-09-07 03:38:24 0000-00-00 00:00:00 2025 0 0 XI, 21 f. 2025 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 620.172.21:629.331:519.61(043.2) 274845 43184.pdf 43184.pdf 1 F9869D4A6BFF4563A27AC70BC0AA5550 ad05a6a6727a6643f0017425530fd3fb57cc96e61b054a3a51cf154a0289754a 6e58fca9-83d8-11f0-9328-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=214914 Fakulteta za strojništvo 0 0 0
