Abstract:Glavni predmet v okviru magistrskega dela je zasnovati in zgraditi dve identični servohidravlično osi, ki bi bili primerni za uporabo v testnih sistemih, bodisi za testiranje materialov in strojnih sklopov ali pa za testiranje in razvoj raznovrstnih regulacijskih algoritmov. Tako bo omogočeno testiranje različnih konceptov regulacije na primerih regulacija sile, regulacija položaja, regulacija ob spremembi bremena, povišani dinamiki s podvojenim pretokom, itd. Prvi del naloge je posvečen spoznavanju različnih izvedb servohidravlični linearnih osi, študiju področij uporabe tovrstnih osi in njihovih posameznih gradnikov. V nadaljevanju bo problematika usmerjena v načrtovanje mehanskih sestavnih delov servohidravlične osi, kjer bo v ospredju ustrezna togost izvedbe osi, kot integraciji ostalih komponent kot je merilni sistem položaja, priključna plošča za en oziroma dva servoventila in hidravličnih akumulatorjev. Dimenzioniranje mehanskih delov servo osi z ustreznimi spremenljivkami bo izvedeno s pomočjo programskega orodja “SOLIDWORKS”. Naslednje poglavje bo namenjeno izbiri in vgradnji senzorskih in krmilnih naprav in merilnik položaja ter servoventil, pri čemer bodo v ospredju karakteristike omenjenih komponent. Za krmiljenje teh komponent bo izbrana ustrezna oprema za zajemanje signalov in vodenje servo osi. Vse omenjene komponente bodo sestavljene v funkcionalno celoto, ter preverjeno njihovo delovanje. V zaključnem poglavju bo prikazan še pristop k snovanju ustreznega fizikalnega modela linearne osi, ki bo služil kot simulacijski model za kasnejše aplikacije regulacij

Title:DESIGNING A SERVO-HYDRAULIC CYLINDER FOR TEST APPLICATIONS
Abstract:The main goal of the present thesis is to design and build two identical hydraulic servo linear actuators for testing applications. In this term, modelling and analysing the rigidity and performance of servocylinder by taking account of the pressured fluid flow into the cylinder and on cylinder extend are illustrated. An electrically operated valve that controls how hydraulic fluid is ported to the cylinder is mounted. Electronic devices such as linear displacement transducer for position measurement and servo amplifier are integrated. In order to drive the electro-hydraulic servo actuator, closed-loop servo system is realized. The first part of the thesis is an introduction to hydraulic servo systems, in which figures the importance and uses of electro-hydraulics servo linear actuator in industrial applications. The following part describes all hydraulic components used, at which specify more about their characteristics and specificities. Final results evaluate the cylinder capabilities and the differences analysis by using a single direct-operated servovalve. Model aspect using two servovalves will be introduced. The chapter will also associate the design of a corresponding mounting plate and assembly table, which are respectively designed for the use of a single servovalve. A hydraulic base plate is also needed for the install. Design dimensioning of the mechanical parts of the servocylinder with their relevant variables will be realized by using 3D CAD Design software program. Final realization contributes to test different problem concepts of electro-hydraulics servo systems in term of control mechanism such as position control, force control, speed control under (or without) load changes.
