Abstract
This paper describes the design and prototyping of a new high performance actuation system that combines the benefits of conventional hydraulic systems and direct drive electrical actuators, namely high torque/mass ratio and modularity. It is referred to as the ElectroHydraulic Actuator (EHA) and results from the fusion of the above mentioned technologies. EHA is a unique device with its own characteristics and requires hydraulic components that are specifically tailored to its needs and requirements. Based on a mathematical model of EHA, the requirements for its components are determined. These requirements are used as a basis for component selection, component modification, and design of a customized new Symmetrical Linear Actuator (SLA). The analysis of EHA presented in this paper is supported by experimental data and, explains the extremely high level of performance attained by a prototype of EHA.
