Analysis For The Power Loss Of Electro Hydrostatic Actuator And Hydraulic Actuator

This article describes the difference between traditional airborne hydraulic actuator and electro hydrostatic actuator in heat dissipation. The power loss of the two systems are analyzed based on the method of energy transfer under different working conditions. To decrease the heating loss of electro-hydrostatic actuator, this paper designs an efficient component of the motor-pump. Theoretical and experimental analysis show that electro hydrostatic actuator is more efficient, and it is available for power saving design according to the need for energy.
