Abstract

In this research, a time-proven concept from the aircraft industry supports development and application of an electrohydraulic actuator (EHA) in stationary application. EHA allows to achieve high power density and high performance in a compact package as well as flexibility in system architecture for stationary applications. The electrohydraulic actuator can eliminate hoses, fittings, valves and fixtures and is easy to integrate into larger systems. Due to good energy efficiency, cooling usually is not required. However, a thermo-dynamic analysis clearly indicates that the electric machine is acting as a high temperature heat source, while the hydraulics of the actuator maintain relatively lower temperature. Therefore, this paper targets the simulation of the thermal behavior of a pump-controlled actuator by means of lumped parameter model in order to predict the operational temperature. The developed model is validated against measurements utilizing thermocouples under various operative conditions. Conclusions are drawn concerning thermal behavior and energy dissipation of the proposed pump-controlled actuator.
