The method combines parametric modelling, CFD analysis, topology optimisation and multi-criteria evaluation. Fifteen control spool bore positions of an NG10 valve were assessed according to pressure drop, turbulent kinetic energy and mass. The vertical position primarily influenced mass, whereas the lateral offset had a stronger effect on the hydraulic criteria. Since the individual optima did not coincide, Pareto and weighted analyses were applied. The configuration with Z = 40 mm and X = 5 mm provided the most balanced solution"},{"@xml:lang":"sl","#text":"V prispevku je predstavljen postopek konstruiranja hidravličnega ventila za kovinske dodajalne tehnologije, ki povezuje parametrično modeliranje, CFD-analizo, topološko optimizacijo in večkriterijsko vrednotenje. Na primeru ventila NG10 je bilo analiziranih 15 položajev izvrtine krmilnega bata glede na tlačni padec, turbulentno kinetično energijo in maso. Rezultati so pokazali, da vertikalni položaj bolj vpliva na maso, bočni odmik pa na hidravlična kriterija. Ker optimumi niso sovpadali, sta bili uporabljeni Pareto in utežena analiza. Kot najbolj uravnotežena se je izkazala konfiguracija z Z = 40 mm in X = 5 mm"}],"edm:type":"TEXT","dc:type":[{"@xml:lang":"sl","#text":"znanstveno časopisje"},{"@xml:lang":"en","#text":"journals"},{"@rdf:resource":"http://www.wikidata.org/entity/Q361785"}]},"ore:Aggregation":{"@rdf:about":"http://www.dlib.si/?URN=URN:NBN:SI:doc-15SI5V2F","edm:aggregatedCHO":{"@rdf:resource":"URN:NBN:SI:doc-15SI5V2F"},"edm:isShownBy":{"@rdf:resource":"http://www.dlib.si/stream/URN:NBN:SI:doc-15SI5V2F/7173a877-631a-4390-92dd-ac9d6ed720b7/PDF"},"edm:rights":{"@rdf:resource":"http://rightsstatements.org/vocab/InC/1.0/"},"edm:provider":"Slovenian National E-content Aggregator","edm:intermediateProvider":{"@xml:lang":"en","#text":"National and University Library of Slovenia"},"edm:dataProvider":{"@xml:lang":"sl","#text":"Univerza v Ljubljani, Fakulteta za strojništvo"},"edm:object":{"@rdf:resource":"http://www.dlib.si/streamdb/URN:NBN:SI:doc-15SI5V2F/maxi/edm"},"edm:isShownAt":{"@rdf:resource":"http://www.dlib.si/details/URN:NBN:SI:doc-15SI5V2F"}}}}
