The transfer matrix of a curved pipe with fluid was derived based on the exact solution of the governing equations, where the axial deformability was also taken into account. Only the steady-state response for the case of harmonic excitations was analyzed. With the formulation of the transfer matrix for a straight pipeand for a curved pipe, a 3-dimensional complex piping system can be easilymodeled. The inviscid fluid-dynamic forces were derived according to theplug-flow approximation and the slender-body theory"},{"@xml:lang":"sl","#text":"V prispevku je na kratko predstavljena metoda prenosnih matrik za modeliranje prenosa vibracij preko cevovoda v prostoru. Na temelju točne rešitve gibalnih enačb je na novo definirana prenosna matrika krožnega loka s tekočino, pri katerem upostevamo tudi osno deformljivost. Osredotočili se bomo na ustaljeno stanje odziva ob harmonski vzbujevalni motnji. Poznavanje prenosne matrike ravne cevi in krožnega loka omogoča modeliranje prenosa vibracij po poljubnem cevovodu, kjer upostevamo učinke pretakajoče se tekočine in nadtlaka v cevi. V numeričnem preizkusu je potrjeno pravilno delovanje metode na podlagi primerjave rezultatov prenosa sile, določene z metodo prenosnih matrik in metodo končnih elementov. Enako je potrjeno tudi s preizkusom. Izkaze se tudi,da je čas preračuna pri uporabi metode prenosnih matrik občutno krajši v primerjavi z metodo končnih elementov"}],"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-URZM4D6M","edm:aggregatedCHO":{"@rdf:resource":"URN:NBN:SI:doc-URZM4D6M"},"edm:isShownBy":{"@rdf:resource":"http://www.dlib.si/stream/URN:NBN:SI:doc-URZM4D6M/6240804d-40e7-4afc-9d6d-9995339522ff/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-URZM4D6M/maxi/edm"},"edm:isShownAt":{"@rdf:resource":"http://www.dlib.si/details/URN:NBN:SI:doc-URZM4D6M"}}}}
