20.500.12556/RUL-146723 Sile in napetosti v tirnici zaradi temperature Forces and stresses in the rail due to temperature V prvem delu diplomske naloge so predstavljeni železniški tir in obe možnosti izvedbe železniškega tira. Podrobno so opisane tudi tirnice in izračun napetosti v tirnicah, ki nastanejo zaradi temperaturnih sprememb. V nadaljevanju so opisane težave, do katerih pride v tirnicah zaradi vedno bolj vročih poletij, in kako se v drugih državah soočajo z izbočenjem tirnic. Osredotočil sem se predvsem na ukrep barvanja tirnic z belo barvo. V zadnjem delu sem izvedel poskus, v katerem primerjam temperaturo bele in nepobarvane tirnice. Na podlagi izmerjenih temperatur sem izračunal sile in napetosti, ki nastanejo zaradi temperaturnih sprememb v obeh tirnicah, ter predstavil končne ugotovitve poskusa. The first part of the thesis presents the railway track and the two railway track options. It also describes the rails in detail and the calculation of the stresses in the rails due to temperature changes. It addresses the problems that are occurring in the rails as a result of increasingly hot summers, and how other countries are dealing with buckling of the rails. I have focused in particular on the measure of painting the rails white. In the last part, I carried out an experiment comparing the temperature of white and unpainted rails. Based on the measured temperatures, I calculated the forces and stresses due to the temperature changes in the two rails and presented the final findings of the experiment. železniški tir tirnica sile napetosti temperatura izbočitev tirnice railway track railway forces stresses temperature rail buckling true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2023-06-09 07:45:29 2023-06-09 07:45:31 2023-06-10 03:37:35 0000-00-00 00:00:00 2023 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1970-01-01 154200 9662.pdf 9662.pdf 1 FD559A7F5398D70FD2BC8352F583E07D c22f56b5a2eff6cd6586a3a514d4efcec4e270e63a65d13bfea8fa82644c28b6 834fc531-0688-11ee-a314-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=169994 Fakulteta za gradbeništvo in geodezijo 0 0 0
