dc.description.abstract | U ovoj tezi je analizirano funkcionisanje dvostepenih hidrauličnih sarvorazvodnika sa povratnom spregom po položaju klipa. Najpre su date definicije, sistematizacija, prikaz konstrukcija, principi rada i istorijski razvoj ovih najsloženijih standardnih elektrohidrauličnih komponenata. Na osnovu kritičkog pregleda dosadašnjih istraživanja i obimne teorijske analize, formiran je detaljan matematički model, čiji su parametri fizičke veličine i čiju složenost jedino limitira mogućnost korektne numeričke integracije. Ovaj model uključuje pojave i veličine od uticaja na ponašanje analiziranih servorazvodnika, tako da može da predvidi njihovo funkcionisanje u širokom opsegu očekivanih radnih režima. Dobijeni rezultati numeričkog modeliranja na personalnom računaru, poređeni su sa odgovarajućim eksperimentalnim. U okviru eksperimentalne analize, pored merenja odgovarajućih statičkih i dinamičkih karakteristika, koje su prvenstveno služile kao sredstvo za utvrđivanje tačnosti modela, razvijene su i posebne eksperimentalne procedure za merenje ili proračunavanje pojedinih fizičkih veličina i parametara iz modela. Vrednost formiranog modela, potvrđena je sa zadovoljavajućom tačnošću. // In this thesis performance of two-stage electrohydraulic servovalves with spool position feedback was analyzed. Primarily, definitions, systematization. description of constructions, principles of operations and historic development of this the most complex standard electrohydraulic components are shown. Based on critical review of hitherto research and extensive theoretical analysis, detailed mathematical model is created. Its parameters are physical quantities and its complexity is only constrained by numerical integration limits. This model comprises phenomena and quantities that have influence on behavior of analyzed servovalves, so it can predict their operation in wide scope of expected working regimes. Results obtained using numerical integration on personal computer were compared with appropriate experimental. Besides measuring static and dynamic characteristics that were used for identifying the accuracy of the model, the special experimental procedures for measuring or calculation of some physical quantities from model were developed. The validity of created model was confirmed with satisfactory accuracy. | en_US |
