Some potential design alternatives are considered. The basic structural element of the damper is a rotary flexible ring. The paper investigates the motion system on the basis ofa set of nonlinear differential equations. By separating the motion into uniform rotary and oscillatory, expanding the equation coefficients into a Taylor's power series and excluding the static members, a system of equations for insignificant oscillations is derived. The system contains inertia, flexible and gyroscopic terms. The equations of motion are derived and the stability conditions for the system's dynamic balance are formulated. Proper consideration is given to other possible loss-of-stability forms and regions of the flexible ring. An analysis of the system's natural frequencies is made.The efficiency estimation of the damper versus various parameters is effected as a result of the expression of the equivalent inertia moment and its limit values</dc:description><dc:description xml:lang="sl">V prispevku so prikazani izvirni dušilniki torzijskih vibracij, ki učinkovito delujejo v sirokem območju motilnih frekvenc. Raziskali smo tudi nekaj možnih oblikovalskih različic. Osnovni sestavni del dušilnika je rotacijski upogibni obroč. V prispevku raziskujemo gibajoči se sistem na osnovi sistema nelinearnih diferencialnih enačb. Z razdelitvijo gibanja na enakomerno vrtenje in nihanje, razvojem koeficientov enačbe v Taylorjevo potenčno vrsto in izključitvijo ustaljenih delov, dobimo sistem enačb za majhna nihanja. Sistem vsebuje vztrajnostne, upogibne in ziroskopske člene. Izpeljali smo gibalne enačbe in formulirali stabilnostne pogoje za dinamično ravnotežje sistema. Ustrezno pozornost smo namenili tudi drugim možnim nestabilnim oblikam in področjem upogibnega obroča. Analizirali smo lastne frekvence sistema. Oceno učinkovitosti dušilnika glede na različne parametre smo pridobili iz izraza za ekvivalentni vztrajnostni moment in njegovih mejnih vrednosti</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-2BIDPB7Q"><edm:aggregatedCHO rdf:resource="URN:NBN:SI:DOC-2BIDPB7Q" /><edm:isShownBy rdf:resource="http://www.dlib.si/stream/URN:NBN:SI:DOC-2BIDPB7Q/1e7792fd-42fa-408e-a492-6c4a5a2e775d/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-2BIDPB7Q/maxi/edm" /><edm:isShownAt rdf:resource="http://www.dlib.si/details/URN:NBN:SI:DOC-2BIDPB7Q" /></ore:Aggregation></rdf:RDF>
