Scheme Analysis of Electro-Hydrostatic Actuator with Control Valve
Aiming at the problems of the typical EHA systems low response, in order to give attention to the efficiency and response, firstly, represents the system composition and operating principle of typical EHA, then, introduces control valve into EHA systems, puts forward three schemes of EHA with control valve. First is EHA with electro-hydraulic servo valve, second is EHA with direct drive valve, and third is EHA with total pressure control valve. Based on the detailed analyses of the system composition and operating principle of these three schemes, use AMESim to simulate each scheme, and compare them. From the simulation results, we can conclude that EHA with control valve will greatly improve the system response. As three transitional schemes, they have practical guidance significance to the research and development of present airborne electro-hydrostatic actuation system.
