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

Screw pump for Electro-Hydrostatic Actuator that enhances backdrivability

2011 11th IEEE-RAS International Conference on Humanoid Robots, 2011
Force sensitivity and backdrivability are vital functionality of actuators to be used in robots that physically interact with humans. Electro-Hydrostatic Actuator (EHA) is a type of a hydraulic actuator with backdrivability. To improve backdrivability of an EHA, reduction of friction, especially static friction is important. This, however, is difficult

Vibration Damping Using Electro-Hydrostatic Actuation Technology

2014
Vibration damping finds its application in almost any system or structure subject to oscillatory excitations. Vehicles, or better, the intrinsic nature of the environments that surround and interact with them demand certain degree of adaptability of the vehicle subsystems to a wide range of working conditions.
