Abstract

Za već napravljen model nosača pogonskog seta dizel električne lokomotive provedena je numerička
analiza pri uvjetima sudara lokomotive. Na nosač je pomoću vijčanih spojeva i zavara montiran pogonski
set dizel električne lokomotive – motor i generator. Opterećenja na nosač koja se razmatraju su sama
težina pogonskog seta, te sile inercije koje na njega djeluju u uzdužnim i bočnim smjerovima. Iznosi sila
inercije definirani su prema standardu EN 12663-1:2010 [1]. Prije provođenja same analize provedena
je verifikacija korištenih konačnih elemenata u odnosu na jednostavan primjer, te ispitana konvergencija
rješenja s obzirom na broj konačnih elemenata. Poslije verifikacije provedena je numerička analiza u
programskom paketu Inventor Nastran® metodom konačnih elemenata. Provedena je analiza za četiri
različita slučaja opterećenja koja promatrani nosač mora izdržati prilikom sudara. Nakon provedene
analize maksimalna naprezanja uspoređena su sa granicom tečenja materijala konstrukcije kako bi se
mogao izvući zaključak zadovoljava li konstrukcija uvjet čvrstoće.

Abstract (english)

For already built genset frame of diesel electric locomotive a numerical analysis in the locomotive
crash conditions has been conducted. Genset frame of diesel electric locomotive is mounted on frame
using bolted and welded connections. Loads on frame that are considered are weight of genset and
forces of inertia that appear along longitudinal and lateral directions. Inertia loads are defined by EN
12663-1:2010 [1] standard. Before conducting analysis, verification of used finite elements has been
made on simple example, convergence of results in relation to the number of finite elements was also
tested. After verification, numerical analysis has been conduncted within Inventor Nastran® using
finite element method. Analysis was conducted for four different load cases which frame needs to
withstand during crash. After conducting the analysis, maximum stresses occuring in the structure
were compared to the construction materials yield limit so that the conclusion could be made if the
construction's stress condition is within those limits.
