Računalniška simulacija tlačnega litja AL zlitine

Vrbančič, Egon (author), Mole, Nikolaj (mentor)

Cilj diplomske naloge je bil izboljšati kvaliteto ulitka s pomočjo računalniških simulacij ter analizirati rezultate vsake izvedene simulacije. Osredotočili smo se predvsem na nastanek poroznosti in zračnih mehurjev med tlačnim ciklom. Simulacije litja smo izvajali s programskim paketom MagmaSoft. Najprej smo opisali proces tlačnega litja in najbolj pogoste napake, ki nastajajo, in delovanje programa MagmaSoft. Nadaljevali smo z analizo in simulacijo ulitka z obstoječimi livnimi parametri, ki so mu sledile simulacije s spremenjenimi livnimi parametri, ki so izboljšali kvaliteto ulitka in so z vidika simulacij ustrezali zahtevam kupca.

• Title: Computer simulation of aluminum die casting

Abstract

The objective of the thesis was to improve the quality of casting with the help of computer simulations and to analyze the result of each simulation. The focus was on the formation of porosity and air bubbles during the press cycle. Casting simulations were performed with MagmaSoft software. First, we described the process of high pressure die casting and the most common errors that occur and functions of MagmaSoft software. We continued with the simulation and the analysis of the casting with the existing casting parameters followed by simulations with modified casting parameters which improved the quality of the casting and in terms of simulations, the customer requirements were met.
