20.500.12556/RUL-95553 Varnostna zavora za profil železniške tračnice Rail profile safety gear V nalogi smo obravnavali varnostno zavoro vozička, ki se mora v primeru pretrga vlečne vrvi zadržati na mestu. Naloge smo se lotili teoretično z dobro poznanimi silami na strmini in jo nadgradili z reševanjem konkretnega problema. Prikazali smo poznane in v praksi uporabljene rešitve za zaviranje dvigal ter jih uporabili kot osnovo za iskanje konstrukcijske rešitve varnostne zavore vozička. Reševanja smo se lotili metodično in ob koncu pripravili predlog rešitve. Končni koncept smo ovrednotili z metodo končnih elementov, s katero smo pri podanih obremenitvah izračunali varnostni faktor konstrukcije \nu = 2,95, ter prikazali vpliv različnih dejavnikov na potrebno silo zaviranja. This thesis describes a railway car safety gear which should keep the car in place in the event that the tow cable breaks. We started by providing a theoretical description of the well-known forces on inclined planes and then proposed a solution for the problem at hand. We described well-established approaches related to elevator safety breaks and used them as the foundation of our search for a suitable railway car safety gear solution. The search was conducted methodically resulting a proposal of a solution. The final concept was evaluated with a finite element analysis, which was used to calculate the safety factor of the design \nu = 2,95, and we also demonstrated the influence of various factors on the braking force. varnostna zavora železniška tračnica zagozda sile na strmini dvigala metoda končnih elementov safety gear rail profile wedge forces on an inclined plane elevators finite element analysis true false false Slovenski jezik Angleški jezik Magistrsko delo/naloga 2017-09-20 15:00:03 2017-09-20 15:00:03 2022-08-10 06:31:31 0000-00-00 00:00:00 2017 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1970-01-01 201363 974.pdf 974.pdf 1 9E9270666F4845CF4A8B07F3FD7297F9 e2d82caed2772b21c96deba90953a5b261fdfdb65d4b9f58a7272e0c2a37f221 c8e881b9-a1b3-11eb-a523-00155dcfd717 20.500.12556/rul/81448b0c-b53e-4cd9-ae30-652591582e49 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=104159 975.pdf 975.pdf 1 E3D063DF007C1D0BA82926FE781A7D27 0c35fdf82ecdf6e47ee047a047d7756fd188fbd82b60662fe7f622aad0f872d1 c8f6db0f-a1b3-11eb-a523-00155dcfd717 20.500.12556/rul/adbb1170-5f1f-4a8f-9a46-15814411f87a https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=104160 976.pdf 976.pdf 1 4F107CA05CB28DC31C3E3B3B849D4270 cd8a3c5eaa219917706cdb8b4eaac1c85d971efb3dd6c2e7935c3cf70b29ba31 c90786bc-a1b3-11eb-a523-00155dcfd717 20.500.12556/rul/059e0542-f909-4f7f-9b44-670b56be231f https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=104161 Fakulteta za strojništvo 0 0 0
