Analysis for the power loss of electro hydrostatic actuator and hydraulic actuator

2015 IEEE International Conference on Advanced Intelligent Mechatronics (AIM), 2015
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.

Multi-discipline simulation of electro-hydrostatic Actuator with Modelica

CSAA/IET International Conference on Aircraft Utility Systems (AUS 2018), 2018
The electro-hydrostatic actuator (EHA) is replacing the traditional hydraulic actuator to become an important part of the aircraft hydraulic system, because of its power by wire, easy maintenance and high reliability. But the application of EHA is limited by its disadvantage of heat dissipation. Therefore, it is necessary to establish the thermodynamic
