Modeliranje in idejna zasnova hidravličnega digitalnega ventila : diplomska naloga univerzitetnega študijaGerkman, MatejVisoko dinamični hidravlični sistemi zahtevajo krmilne ventile, ki imajo dobre dinamične lastnosti. Trenutno se v teh aplikacijah uporabljajo servoventili, ki pa vedno ne morejo zadostiti vsem ... zahtevam, zato se iščejo novi alternativni pristopi. Eden izmed obetajočih pristopov je digitalna hidravlika. Osnovna ideja digitalne hidravlike je v vzporedni vezavi dvo položajnih on/off ventilov skupaj z inteligentnim krmilnikom. Predstavljene so karakteristike različnih načinov kodiranj digitalnih ventilskih sistemov. Kot najboljša rešitev se pogosto izkaže PNM kodiranje, kjer se uporablja veliko število enakih ventilov. Pokazano je, da je miniaturizacija pomembna pri uvajanju digitalne tehnike na področje hidravličnih ventilov. Na podlagi poznavanja statičnih in dinamičnih lastnosti servo ventilov smo določili ustrezne statične in dinamične lastnosti digitalnega ventila. Predstavljene so tudi trdnostne analize enostavnega sedežnega on/off ventila s pomočjo MKE (Metode končnih elementov) ter tlačne in tokovne analize CFD (Computer Fliud Dynamic) pri katerih smo analizirali aksialne sile na čep. Na podlagi rezultatov simulacij so določeni vplivni in izhodiščni parametri za zasnovo novega digitalnega ventila.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [M.
