20.500.12556/DKUM-82595 Numerična simulacija odrezavanja gredic magistrsko delo Numerical simulation of slab cutting Za potrebe naročila podjetja SIJ Ravne Systems je bilo treba skonstruirati škarje za rezanje gredic v vročem in pripadajoči valjčni progi. Od tega je naš del obsegal konstrukcijo sestavov noža, ki sta bila koncipirana in snovana po delih in razdelana v razdelavi. Pripravljeni so bili materialni modeli uporabljenih materialov, izvedeni sta bili termična in eksplicitna simulacija za validacijo konstrukcije sestavov noža in poleg ostalih rezultatov so bile pri tem pridobljene največje sile, ki delujejo na škarje v procesu rezanja. Pripravljene so bile tudi sestavne in delavniške risbe delov sestavov noža in v zaključku, po razmisleku glede na izpolnjevanje zahtev zahtevnikov, je bila ugotovljena ustreznost konstrukcije sestavov noža in rezultatov simulacij. For the SIJ Ravne Systems order demands, shears for slab shearing in the hot and the corresponding roller line had to be constructed. This included the construction of the knife assemblies, which were conceived and designed piece by piece and elaborated during the construction. Material models of the used materials were prepared, a thermal and explicit simulation were performed to validate the construction of the knife assemblies and in addition to other results, the maximum forces acting on the shears during the shearing process were obtained. An assembly and workshop drawings of the parts of the knife assemblies were also prepared. Finally, after some reflection on the topic of meeting the necessary requirements, the adequacy of the construction of the knife assemblies and the results of the simulations were determined. rezanje v vročem gredica škarje sestav noža materialni model konstruiranje termična simulacija eksplicitna simulacija hot shearing slab shears knife assembly material model construction thermal simulation explicit simulation true true false [G.
