The model assumes that the profile of the bellows is composed of double circular arcs with different radii of curvature and considers the effects of bellows stretching deformation. Based on this model, this paper proposes a hybrid analysis method that uses the CAS geometric analytical method instead of the computationally expensive fluid-structure interaction (FSI) static analysis. Using the geometric parameters and internal pressure of the CAS under loaded equilibrium, as derived from the proposed double-arc model, an FSI simulation model of the CAS is established in Fluent for subsequent static and dynamic characteristic analysis. The feasibility of the double-arc model and the proposed analysis method is validated through static and dynamic characteristic experiments of the CAS. Furthermore, the hybrid analysis method is applied to analyze the dynamic response of an air spring vibration isolation system. A comparison with the results of the traditional full-process FSI simulation demonstrates that the proposed method improves the average computation efficiency by approximately 10.8 % while maintaining computational accuracy</dc:description><dc:description xml:lang="sl">V članku je predstavljen nov analitični model z dvojno krožno krivuljo za analizo statičnih značilnosti valovitih zračnih vzmeti (CAS). Model predpostavlja, da je profil meha sestavljen iz dveh krožnih lokov z različnima polmeroma ukrivljenosti ter upošteva vpliv raztezne deformacije meha. Na osnovi tega modela je predlagana hibridna analiza, ki uporablja geometrijski analitični pristop kot nadomestilo za računsko zahtevno statično analizo interakcije med tekočino in strukturo (FSI). Z uporabo geometrijskih parametrov in notranjega tlaka v stanju obremenjenega ravnovesja določenih s predlaganim geometrijskim modelom, je bil v programu Fluent vzpostavljen FSI-simulacijski model za nadaljnjo analizo statičnih in dinamičnih značilnosti. Ustreznost modela in predlagane analitične metode je bila potrjena z eksperimentalnimi preizkusi statičnih in dinamičnih lastnosti izbrane zračne vzmeti. Nadalje je bila hibridna metoda uporabljena za analizo dinamičnega odziva sistema za izolacijo vibracij z zračno vzmetjo. Primerjava z rezultati tradicionalne celovite FSI-simulacije je pokazala, da predlagana metoda izboljša povprečno računsko učinkovitost za približno 10,8 %, ob hkratnem ohranjanju natančnosti izračunov</dc:description><edm:type>TEXT</edm:type><dc:type xml:lang="sl">znanstveno časopisje</dc:type><dc:type xml:lang="en">journals</dc:type><dc:type rdf:resource="http://www.wikidata.org/entity/Q361785" /></edm:ProvidedCHO><ore:Aggregation rdf:about="http://www.dlib.si/?URN=URN:NBN:SI:DOC-E3F14PUV"><edm:aggregatedCHO rdf:resource="URN:NBN:SI:DOC-E3F14PUV" /><edm:isShownBy rdf:resource="http://www.dlib.si/stream/URN:NBN:SI:DOC-E3F14PUV/69cd944a-ffbc-4483-aedf-b377c78f721c/PDF" /><edm:rights rdf:resource="http://rightsstatements.org/vocab/InC/1.0/" /><edm:provider>Slovenian National E-content Aggregator</edm:provider><edm:intermediateProvider xml:lang="en">National and University Library of Slovenia</edm:intermediateProvider><edm:dataProvider xml:lang="sl">Univerza v Ljubljani, Fakulteta za strojništvo</edm:dataProvider><edm:object rdf:resource="http://www.dlib.si/streamdb/URN:NBN:SI:DOC-E3F14PUV/maxi/edm" /><edm:isShownAt rdf:resource="http://www.dlib.si/details/URN:NBN:SI:DOC-E3F14PUV" /></ore:Aggregation></rdf:RDF>
