Sand casting simulation of aluminium alloy wheel

U okviru ovog završnog rada prikazana je simulacija lijevanja kotača od aluminijeve legure AlSi13 u pješčani kalup. Shodno tomu definiran je uljevni sustav i provedena je simulacija u programu QuickCAST. Na temelju rezultata simulacije dodan je sustav napajanja s ciljem otklanjanja poroznosti unutar odljevka (kotača). U laboratoriju za Ljevarstvo u prostorima Fakulteta strojarstva i brodogradnje izliven je kotač sa iskustvenim uljevnim sustavom i sustavom napajanja. Nakon lijevanja odljevak je izmjeren i podvrgnut radiografskom ispitivanju. Prema izmjerama napravljen je CAD model i simulacija u programu. Rezultati radiografskog ispitivanja i simulacije su se većim dijelom poklapali osim manjih poroznosti u jednom dijelu vijenca kotača.Within this thesis, a casting simulation of aluminum alloy AlSi13 wheel in a sand mold is presented. Accordingly, the gating system was defined and a simulation was performed in the QuickCAST. Based on the simulation results, a feeding system was added with the aim of eliminating porosity inside the casting (wheel). A wheel with experiential gating system and feeding system was casted in the Foundry Laboratory at the Faculty of Mechanical Engineering and Naval Architecture, University of Zagreb. After the casting process, the casting was measured and subjected to radiographic examination. According to the measurements, a CAD model and simulation in the QuickCAST were made. The results of the radiographic examination and simulation largely coincided except for minor porosities in one part of the wheel rim
