Analysis, design and simulation of a collaborative rectification hydraulic pump

This paper presents the analysis, design and simulation of a novel hydraulic pump driven by linear electric motor. The pump consists of two collaborative rectification cells. A cell contains a cylinder, a four-way spool valve and a linear electric motor. Its working principium is expatiated, and the kinematic flow rate of the pump is studied. The simulation model is developed by AMESim (Advanced Modeling Environment for performing Simulation of engineering systems) and MATLAB Simulink software package. The model is used to simulate flow rate of interface port under different load pressure.
