Karakterizacija ohišja piezoaktuatorja : diplomsko delo Visokošolskega strokovnega študijskega programa I. stopnje strojništvoRobida, DomenV diplomski nalogi je zasnovanih več prototipov piezo aktuatorja za katerega so izvedene podrobne analize z metodo končnih elementov. Aktuatorji so modularno grajeni, kar zagotavlja večjo ... fleksibilnost in jih je možno enostavno in hitro vgraditi v različne hidravlične ali pnevmatične ventile. V prvem delu so opisane statične in dinamične karakteristike piezoelementov, ki predstavljajo osnovna teoretična izhodišča za izdelavo piezo aktuatorjev. V drugem delu je predstavljenih več konceptov piezo aktuatorjev in potrebnih sestavnih elementov za zagotavljanje ustrezne vgradnje na ventil, vgradnje piezoelementov v aktuator, vodenja piezoelementov in njihovega prednapetja. Na podlagi izdelanih 3D modelov konceptov je izvedena podrobnejša analiza z metodo končnih elementov. Podrobneje so analizirane notranje napetosti in aksialne deformacije glavnih sestavnih delov aktuatorja, ki bistveno vplivajo na statične in dinamične lastnosti celotnega piezo aktuatorja. Analiza je osredotočena predvsem na velikost aksialnih deformacij, ki direktno vplivajo na zmanjšanje pomika aktuatorja. V zaključku je prikazana primerjava rezultatov notranjih napetosti in deformacij posameznih konceptov na podlagi katerih je določen koncept z najmanjšimi notranjimi napetostmi in koncept z najmanjšimi aksialnimi deformaciji.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [D.
