As an important development direction in the aviation field, variant aircraft is receiving increasing attention, and low-power mutable aerodynamic shape actuator are its key components. This article proposes use of electro-hydraulic with hydraulic lock module (EHA-HL) to drive mechanism aircraft, which can reduce energy consumation. Further, principle analyzed four quadrants, mathematical models established. Through AMESim simulation, EHA-HL could decrease current through locking under...
The reduction of fluid ripple in pipes is extremely important for the reliability and safety aircrafts ships. Currently, most researches only pay attention to discharge port ignore suction inherent characteristic axial pump between both ports, which may cause significant underestimation especially closed-loop hydraulic system. Therefore, aim this study propose a novel passive attenuator, can simultaneously reduce pulsation axial-piston pump, adapt condition frequent change load reversing...
Due to asymmetry of the piston effective area on both sides single rod cylinder, its performances are limited compared double cylinder. In this paper, a novel electro-hydrostatic asymmetric actuator is proposed, in which displacement pump used control improve system properties. The possesses two states, large and small displacement, respectively less chamber chamber. Mathematical simulation models constructed analyze internal parameters system. By analyzing force load curve, case no increase...
