Rezumat: Obiectivul acestei lucrari este analiza regimului tranzitoriu al unui actuator electromecanic cu lichid volatil, pe baza functiei indiciale, determinata experimental. Determinarile experimentale au fost efectuate pentru doua lichide volatile cu volatilitate diferita si pentru diferite pozitii de lucru ale actuatorului. Pe baza determinarilor experimentale privind alungirea actuatorului, a fost determinata functia indiciala a acestuia, fiind analizat regimul lui tranzitoriu.

Cuvinte cheie: studiu; actuator electromecanic; lichid volatil; regim tranzitoriu; functie indiciala


Abstract: The objective of this paper is analysis of transient regime of an electromechanical actuator with volatile liquid, based on the unit step response determined experimentally. Measurements have done for two volatile liquids with different volatility and for different operating positions of the actuator. Based on the measurements done concerning actuator elongation, the actuator unit step responses were determined, its transient behavior being analyzed.

Keywords: study; electromechanical actuator; volatile liquid; transient regime; unit step response
