Abstract

Delo opisuje optimiziranje oziroma zmanjševanje mase nosilnega okvirja orodja za brizganje pene. Najprej je bilo potrebno določiti katere nosilne dele je smiselno analizirati. Nato se je ugotovilo trenutno obremenitveno stanje nosilnega okvirja. To je bilo izvedeno s pomočjo MKE analize v programu Simulia Abaqus. Numerične modele je bilo nato potrebno prenesti v program ProTOp, kjer se je izvedla optimizacija. Na koncu se je izvedla še analiza optimiziranih nosilnih elementov. Z pozitivnimi rezultati slednje je bila naloga končana. Končni rezultat je zmanjšanje mase nosilnih delov iz 1581,4 kg na 1231,1 kg, kar pomeni približno 22% redukcijo mase. Za orodje z skupno maso 5300 kg se tako ni doseglo željene redukcije za 800 kg, saj imajo ostali elementi na orodju preveč geometrijskih omejitev.

Secondary title: Strength analysis and optimization of mold tool mounting stock
Secondary abstract: This work describes an approach to optimization of a mold mounting frame with the main goal of weight reduction. First, it was necessary to determine which parts of the mounting frame would make sense to be analyzed. Then, the actual state of stress and deformation within these parts was found by FEM analysis with Simulia Abaqus. The numerical models were then transferred to CAESS ProTOp where the optimization was performed. Finally, the validation of results was done by FEM analysis of optimized load-carrying parts. The final result is a weight reduction of the load-carrying parts from 1581,4 kg to 1231,1 kg, which is around 22%. The target goal of 800 kg weight reduction of the whole foaming tool, with a weight of 5300 kg, was not reached due to a significant number of complex parts within the tool with too many geometrical constraints.
