Abstract

V magistrski nalogi je opisan postopek konstruiranja premnika avtomobila. Cilj te naloge je skonstruirati model premnika, ki bo vzdržal obremenitve ob predpostavljenih pogojih obratovanja. Geometrijo premnika smo določili s pomočjo literature, ki je zapisana v virih. Najprej smo določili točke v katerih bo premnik vpet, nato pa v teh točkah predpostavili obremenitve. Točke vpetja premnika smo določili ob predpostavljeni geometriji celotnega vzmetenja avtomobila. Nato smo s pomočjo predpostavk izračunali obremenitve, ki delujejo na točke vpetja premnika pod različnimi pogoji. Na osnovi točk vpetja premnika smo skonstruirali začetni 3D model premnika. S pomočjo numerične simulacije po MKE smo optimizirali 3D obliko premnika, prikazali rezultate primerjalne napetosti po Missesu, glavne napetosti v kritičnem prerezu premnika ter pomike pri danih obremenitvah. Glede na dobljene rezultate glavnih napetosti v kritičnem prerezu smo določili življenjsko dobo izbranega dela konstrukcije.

Secondary title:	Construction of an electric car upright
Secondary abstract:	The thesis describes the design process of a car upright. The aim of this paper is to construct a model upright, which will sustain the assumed load conditions. The geometry of the upright carrier was determined by means of literature, which is recorded in the works cited page. First, we determined the point where the upright would be mounted, and then we assumed the burden in these sections. The upright mount points were determined assuming the geometry of the total suspension of the car. Then we calculated the loads acting on the upright mount point under different conditions by using suppositions. Based on the upright mount points, we constructed an initial 3D model of the axle beam. With the help of a numerical simulation using FEM analysis, we optimized the 3D shape of the upright, we showed the results of the equivalent stresses according to Misses, the principal stresses in the critical cross-section of the axle beam and movements at the given loads. According to the results of principal stresses in the critical section we have determined the fatigue life of a selected part of the structure.
