Vpliv položaja ojačitvenih reber na dinamične značilnosti obodno vpetih okroglih lesenih plošč : diplomsko delo (univerzitetni študij) = Influence of reinforcing braces possition on dynamic characteristics of peripherally fixed round wooden plates : graduation thesis (university studies)Erman, AlešAnalizirali smo vpliv položaja ojačitvenih reber na dinamične značilnosti obodno vpetih okroglih lesenih plošč. Ob predpostavki, da sta material in vpetje znana, so razlike v dinamičnih značilnostih ... plošč le posledica variabilnosti položaja ojačitvenih reber in njihovih dimenzij. Rezultate meritev smo preverili z metodo končnih elementov (MKE) in ugotovili, da je uporabna za napovedovanje dinamičnih značilnosti plošč. Zaradi dodanih ojačitvenih reber se frekvence posameznih nihajnih načinov zvišajo oziroma znižajo. Premik frekvence nihajnega načina je odvisen od lege ojačitvenega rebra in lege nodalne linije. Če ena ali več nodalnih linij nihajnega načina sovpada s položajem enega ali več ojačitvenih reber, je vpliv le-tega/teh na frekvenco nihajnega načina minimalen. Če leži rebro poleg nodalne linije, ali pa jo celo seka pod kotom, se frekvenca nihajnega načina zviša. S specifično postavitvijo reber lahko nekatere nihajne načine celo eliminiramo.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [A.
