Abstract:Prispevek predstavlja začetno raziskovalno delo na področju reducirane globalne parametrizacije za optimizacijo oblike konstrukcijskih delov. Z besedo 'reducirana' označujemo parametrizacijo z zelo majhnim številom vplivnih parametrov - to število mora biti neodvisno od kompleksnosti geometrije konstrukcijskega dela, ki ga optimiramo. Za osnovo predlaganega pristopa smo privzeli predpostavko, da se oblika konstrukcijskega dela lahko spreminja samo v izbranih naravnih načinih. Ti načini so med sabo neodvisni in hierarhično razporejeni. To omogoča optimizacijo s prilagodljivo natančnostjo v odvisnosti od računske zahtevnosti problema.

Title:Reduced global parametrization for shape optimization
Abstract:The paper presents initial research work in the field of reduced global parametrization for shape optimization of structural parts. By the word 'reduced' we denote a parametrization with a very low number of influential parameters; this number has to be independent of the geometrical complexity of the structural part to be optimized. The basis of the proposed approach is given by the assumption that the shape of the structural part can be varied only by selected natural modes. These modes are mutually independent and hierarchically arranged. This enables optimization with variable accuracy in dependence on computational demandingness of the problem.
Keywords:global parametrization, shape optimization, structural parts
