Two principal geometry-dependent parameters are considered for the optimisation purposes: contact stress and relative sliding. Both depend on the geometry of the contacting surfaces, which is mainly influenced by the addendum modification coefficient. To maxmise the service life of the gear pair, optimum values of this coefficient have to be chosen, in order to satisfy prescribed criteria for specific sliding and Hertz pressure while all the design boundary conditions are fulfiled. An adaptive-grid-refinement algorithm procedure is applied and the gear-flank geometry resulting from the optimisation algorithm is subsequently analysed. The sliding, circumstances are compared and evaluated. A FEM contact algorithm using the Lagrange multiplier method and a spline-based geometry definition is applied to calculate the contact stress distribution patterns and to show the applicability of the computational methods to the general gear design"},{"@xml:lang":"sl","#text":"V prispevku je opisano orodje za optimiranje geometrijske oblike zob kot dodatek k splošnim postopkom zasnove zobnikov. Algoritem omogoča zmanjšanje in enakomerno porazdelitev obrabe in jamičenja zob v ubiru. V postopku optimiranja upoštevamo dva glavna parametra, ki sta odvisna od geometrijske oblike zob: kontaktne napetosti in relativno drsenje. Oba sta odvisna od oblike kontaktne površine, ki pa je v veliki meri odvisna od koeficientov premikov profila. Če želimo doseči čim večjo življenjsko dobo zobnikov, moramo poiskati optimalne vrednosti koeficientov premikov profila, z upoštevanjem vseh preostalih robnih pogojev, ki so predpisani za zasnovo zobnikov. Uporabljen je algoritem adaptivnega izboljšanja mreže. V nadaljevanju prispevka je preverjena oblika zob, dobljena po predlaganem postopku. Prav tako so primerjane in ocenjene drsne razmere za obe obliki zob. Prikazana je možnost uporabe MKE v postopku snovanja zobnikov. Za izračun kontaktnih napetosti je uporabljen algoritem z metodo Lagrangeovih množiteljev po metodi končnih elementov, kontaktne površine pa so dodatno opisane s parametričnimi zlepki"}],"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-UDWIA2RV","edm:aggregatedCHO":{"@rdf:resource":"URN:NBN:SI:DOC-UDWIA2RV"},"edm:isShownBy":{"@rdf:resource":"http://www.dlib.si/stream/URN:NBN:SI:DOC-UDWIA2RV/fe51e748-2944-46cd-ab62-ddff925d1a6c/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-UDWIA2RV/maxi/edm"},"edm:isShownAt":{"@rdf:resource":"http://www.dlib.si/details/URN:NBN:SI:DOC-UDWIA2RV"}}}}
