Parametrična analiza navojnega vretena linearnega aktuatorja : magistrsko delo magistrskega študijskega programa II. stopnje StrojništvoFranken, MaticPri načrtovanju navojnih vreten, ki niso namenjena premagovanju velikih bremen, se odločamo za kombinacijo materialov polimerne matice in jeklenega vijaka. Zaradi izrazite razlike v trdnosti ... materialov, nam matica predstavlja kritično komponento. Magistrska naloga predstavi primerjavo izračuna koncentracij napetosti v kritičnih točkah navoja z uporabo analitičnih in numeričnih metod. S primerjavo smo pokazali omejenost uporabe analitičnih metod, ki temeljijo na teoriji spenjalnih vijačnih zvez, saj z njimi ne dosežemo zadovoljive natančnosti. Z uporabo metode končnih elementov, smo analizirali vpliv geometrijskih parametrov navoja na pojav koncentracij napetosti v dveh kritičnih točkah. Obravnavali smo več različnih načinov osnega vpetja navojnega vretena ter ocenili njihovo ustreznost z vidika pojava koncentracij napetosti. Ugotovljeno je bilo, da je pomik zaokrožitve temena navoja vijaka v koren navoja matice najučinkovitejši način zmanjševanja kontaktnega tlaka.Type of material - master's thesis ; adult, seriousPublication and manufacture - Ljubljana : [M.
