Abstract
Današnji globalni trendovi željezničkog transportnog prometa nalažu skidanje svih nepotrebnih komponenata s vagona u cilju smanjenja mase vagona. Upravo zbog toga rodila se ideja analize opravdanosti upotrebe mehanizma za dodatno pridržavanje vrata vagona Falns 48. Vagon Falns 48 namijenjen je u prvom planu za prijevoz željezne rude. Naime, izbacivanjem ovog mehanizma masa vagona mogla bi se smanjiti za 276 kg, ali bi se maksimalni pomaci donjeg brida vrata vagona povećali s 0,04 mm na 3,76 mm. To povećanje maksimalnih pomaka donjeg brida vrata vagona, prilikom transporta tereta može uzrokovati njegovo istjecanje iz vagona te rasipanje po tračnicama, što je strogo zabranjeno. Prema tome, nužno je provesti optimiranje kako bi se pronašao određeni kompromis, odnosno pronašlo optimalno rješenje. Dakle, metodom konačnih elemenata analizirani su pomaci i naprezanja početne konstrukcije vagona s i bez upotrebe mehanizma za dodatno pridržavanje vrata te je proveden postupak optimiranja. Optimiranje je provedeno s ciljem smanjenja maksimalnih pomaka donjeg brida vrata vagona nauštrb povećanja mase. Isto tako, predloženo je novo konstrukcijsko rješenje vrata vagona te je provedeno optimiranje predloženog konstrukcijskog rješenja. Analizom dobivenih rezultata donesen je zaključak da upotreba mehanizma za dodatno pridržavanje vrata vagona Falns 48, za slučaj transporta željezne rude, nije opravdana.
Abstract (english)
Today's global trends in freight transport demand removal of all unnecessary freight wagon components in order to reduce mass. Because of that, the idea of a validity analysis of the additional door holding mechanism on freight wagon type Falns 48 was born. By removing this mechanism, the mass of the wagon could be reduced by 276 kg, but the maximum deformation of the doors lower edges would increase from 0,04 mm to 3,76 mm. This increase in the maximum deformation of the wagon doors lower edges can cause the cargo to leak out the wagon and fall down on the rails, and that is strictly forbidden. Therefore, it is necessary to implement optimization to find a certain compromise, or find the optimal solution. By applying the finite element method the deformations and stresses of the initial constructional solution of the wagon doors, with and without using the additional door holding mechanism, were analyzed. After that, the optimization process was carried out. The aim of the optimization is to reduce the maximum deformation of the doors lower edges, at the expense of mass increase. Also, a new constructional solution of the wagon doors was proposed and optimization of the proposed constructional solution was carried out. By analyzing the results, it was concluded that the use of the additional door holding mechanism on freight wagon Falns 48, in the case of transporting iron ore, is not justified.
