High-stretch, tendon-driven, fiber-reinforced membrane soft actuators with multiple active degrees of freedom [PDF]
Communications EngineeringMost soft actuators with multiple active degrees of freedom do not take advantage of the full extensibility of elastomer. Here we introduce a technique for better utilizing this extensibility for more versatile soft actuators. Embedded tendons that slide

Delay Analysis and the Control of Electro-Hydrostatic Actuators
Applied Sciences, 2022 The electro-hydrostatic actuator (EHA) has a high energy density and a compact structure so it is widely used in all/more electric aircraft. To gain energy-saving capability, the hydraulic lock can be applied in the EHA system, which can overcome the ...

Research on Fault Diagnosis Method of Electro‐Hydrostatic Actuator [PDF]
Shock and Vibration, 2021 Electrohydrostatic actuator is a type of actuator that uses hydraulic energy as the energy transmission carrier, which has the advantages of small size and high power. Since it is commonly used in harsh conditions such as strong vibration, high pressure, and heavy loads, condition monitoring and fault diagnosis of its hydraulic system are particularly ...

Results of a Feasibility Study of a Prognostic System for Electro-Hydraulic Flight Control Actuators
International Journal of Prognostics and Health Management, 2021 Electro-Hydraulic Servo-Actuators (EHSA) are currently the most used actuation technology for primary flight control systems of civil and military aircrafts. Although some alternatives have emerged in the last decade, such as electromechanical or electro-

A Critical Analysis of Flow-Compensated Hydrostatic Single Rod Actuators: Simulation Study
Actuators, 2020 It is well established that the differential cylinder area in pump-controlled single-rod actuators creates the need of correctly switching the connections between the main circuit lines and a charge circuit, in order to provide means for equalising the ...
