A vibration model for the hexapod table is developed and the relevant explicit equations are derived. In the vibration equation of the table, the pods are assumed as spring-damper systems and the equivalent stiffness and damping of the pods are evaluated using experimental results obtained by modal testing on one pod of the hexapod table. The results of the analytical approach have been verified by FEM simulation. The theoretical and FEM results exhibit similar trends in changes and are close to each other. The vibration of the table in different positions has been studied for rough and finish machining forces for both down and up milling. The ranges of resonance frequencies and vibration amplitudes have also been investigated. The safe functional modes of the table in terms of its upper platform's position have subsequently been determined"},{"@xml:lang":"sl","#text":"Šesteronožni mehanizmi s paralelno kinematiko od prihoda v 60. letih prejšnjega stoletja postajajo vse bolj razširjeni. Med drugim se uporabljajo v avtomobilskih in letalskih simulatorjih, za izolacijo vibracij in v napravah za nakladanje/razkladanje. Nove možnosti uporabe se pojavljajo tudi pri obdelovalnih strojih v sestavih miz in platform za vretena. Pomembna značilnost paralelnih šesteronožnih mehanizmov je njihova gibljivost, zaradi katere so zelo primerni za visokohitrostne obdelovalne stroje. Dodatna prednost šesteronožnih mehanizmov na obdelovalnih strojih je tudi šest prostostnih stopenj. Te možnosti šesteronožnih mehanizmov je mogoče uporabiti tako pri razvoju novih visokohitrostnih obdelovalnih strojev kakor tudi pri razmeroma poceni nadgradnji obstoječih ročnih strojev v napredne šestosne obdelovalne stroje"}],"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-W9Z7LF4E","edm:aggregatedCHO":{"@rdf:resource":"URN:NBN:SI:doc-W9Z7LF4E"},"edm:isShownBy":{"@rdf:resource":"http://www.dlib.si/stream/URN:NBN:SI:doc-W9Z7LF4E/27e0a277-3d6a-4604-a3dc-853c4441c2d3/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-W9Z7LF4E/maxi/edm"},"edm:isShownAt":{"@rdf:resource":"http://www.dlib.si/details/URN:NBN:SI:doc-W9Z7LF4E"}}}}
