The numerical investigation was performed using the finite element method (FEM) with the Simufact Forming simulation software suite. The simulations investigated the effect of tubular specimen wall thickness on the kinematics of metal flow and the geometry of produced shafts. The results were validated in experimental tests using a forging machine designed specifically for this purpose"},{"@xml:lang":"sl","#text":"Votle dele, kot so gredi spremenljivega premera in osi, je mogoče izdelovati z različnimi postopki preoblikovanja kovin, med katerimi so najbolj priljubljeni rotacijsko kovanje, ekstrudiranje, hidroforming, potisno preoblikovanje in rotacijsko ekstrudiranje. Rotacijsko stiskanje je inovativna tehnologija preoblikovanja za izdelavo votlih kovinskih delov, ki je bila razvita na Tehniški univerzi v Lublinu. V procesu rotacijskega stiskanja sodelujejo trije valji, ki se ne le vrtijo, temveč se tudi premikajo proti osi obdelovanca. Kot surovci pri rotacijskem stiskanju se uporabljajo kosi komercialnih cevi ali tulcev, ki se vrtijo in obenem tanjšajo pod vplivom delovne površine orodij. Premer obdelovanca se tako postopoma zmanjšuje. Rotacijsko stiskanje ima svoje mesto v industriji zaradi preproste zasnove procesa in primernosti za avtomatizacijo"}],"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-HJ1DMNK7","edm:aggregatedCHO":{"@rdf:resource":"URN:NBN:SI:doc-HJ1DMNK7"},"edm:isShownBy":{"@rdf:resource":"http://www.dlib.si/stream/URN:NBN:SI:doc-HJ1DMNK7/fe1965d6-6cc4-4c69-b85b-854e686a708e/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-HJ1DMNK7/maxi/edm"},"edm:isShownAt":{"@rdf:resource":"http://www.dlib.si/details/URN:NBN:SI:doc-HJ1DMNK7"}}}}
