| dc.description.abstract | U ovoj doktorskoj disertaciji istraživani su osnovni i dodatni temperaturni naponi u kontinualno zavarenim šinama primenom numeričke analize zasnovane na metodi konačnih elemenata. Glavni ciljevi istraživanja su: (1) određivanje temperaturnog polja šine i osnovnih temperaturnih napona usled neravnomerne raspodele temperature, (2) kvantifikovanje preraspodele temperature i osnovnih temperaturnih napona usled prenosa toplote između šine i praga, kao i između nožice šine i zastora od tucanika, (3) uporedna analiza osnovnih temperaturnih napona određenih korišćenjem numeričke analize sa osnovnim temperaturnim naponima određenim u skladu sa inženjerskom praksom, (4) kvantifikovanje uticaja parametara koloseka i mosta na dodatne temperaturne napone u kontinualno zavarenim šinama na mostu i definisanje smernica za integralno projektovanje konstrukcija koloseka i mosta... | sr |
| dc.description.abstract | In this doctoral dissertation basic and additional temperature stresses in continuously welded rails were investigated using numerical analysis based on the finite element method. The main aims of the research are: (1) determination of the rail temperature field and basic temperature stresses due to uneven temperature distribution, (2) quantifying the redistribution of temperature and basic temperature stresses due to heat transfer between the rail and the sleeper, as well as between the rail foot and the ballast, (3) comparative analysis of basic temperature stresses determined by using numerical analysis with the basic temperature stresses determined in accordance with engineering practice, (4) quantifying the influence of track and bridge parameters on the additional temperature stresses in continuously welded rails on the bridge and defining guidelines for the integral design of track and bridge structures... | en |
