Design and Performance Analysis of a Local Electro-hydraulic Generation System

This paper is aimed at a design of a local electro-hydraulic generation system following the trend of more electric aircraft. This design integrating a motor and a pump is called electric hydraulic pump and it is applied as the power unit of the whole system. Modeling and sub-models based on AMESim are built as well as the primary experiment validation. To enhance the precision of the model in AMESim and verify the pressure fluctuation as well as the pulsation when the system is working, the model of pump designed as a super component with nine pistons is present. Furthermore the leakage from the swash plate and the slipper, pistons and the valve plate are taken into consideration. The preliminary experiments show that the performance of the local electro-hydraulic generation system is also acceptable. Electric hydraulic pump that brings the weight and noise benefits can be the substitute of traditional pumps and motors.
