Roboto valdymo sistema / Robot control systemMitka, Darius 21 June 2004 (has links)
The final work of master studies reviews various industrial robots constructions and parameters, from which they are characterized. Robotics systems and control of flexible production have been discussed in here. Various robots’ drives and their control advantages and disadvantages are analyzed. In the practical part original robot global movement platform is suggested and algorithm of two flexible production bays handling is created. Static characteristics of linear drive used in platform are calculated. Using software package “Matlab Simulink” model of symmetrical linear induction motor (LIM) is created and dynamic characteristics are gained. Concluding part presents inferences and suggestions.

Universalios sklendės tiesiaeigės pavaros tyrimas / Research on the Universal Linear Electric DriveInčirauskaitė, Asta 20 June 2011 (has links)
Šiame baigiamajame darbe apžvelgtos dulkių sprogimų atsiradimo priežastys bei sprogimų plitimų mechanizmas. Aprašyti sprogimų žemės ūkio įmonėse padariniai. Aptartos techninės priemonės, įgalinančias lokalizuoti pirminius silpnus dulkių sprogimus ir taip išvengiant stiprių, griaunamosios jėgos sprogimų. Išanalizuotos ugnį užtveriančių ir technologinių universaliųjų sklendžių tiesiaeiges elektros pavaros. Naudojant programinį modeliavimo paketą Matlab Simulink sudarytas universaliosios sklendės tiesiaeigės pavaros modelis ir gautos dinaminių charakteristikų imitacijos kreives. Naudojant programinį paketą SolidWorks sumodeliuota universalioji sklendė ir gauta smūginės bangos slėgio veikiamo sklendės judamojo elemento deformacija ir judamojo elemento deformacija, kai induktoriaus aktyviojoje zonoje įtaisyti papildomi atraminiai guoliai. Baigiamojo darbo pabaigoje pateiktos išvados ir pasiūlymai. / The final work of master analyses the causes of dust explosions and explosions spread mechanism. A short overview of the explosions effects in the agro - industry is presented. Technical devices enabling the localization of primary weak dust explosions and so avoiding the strong, destructive force explosions are discussed. Fire blocking and universal linear electric drives are analyzed. Using software package Matlab Simulink model of universal linear electric drive is created and dynamic characteristics are gained. Using software package SolidWorks model of universal linear electric drive is created and valves mobile element deformation and deformation of the mobile element, when there are installed additional supporting bearings in the inductor active zone are obtained when mobile element is affected by the pressure of the explosion wave. Concluding part presents inferences and suggestions.
