Mechanical and Hydraulic Joint Modeling and Simulation about Elec-Pump

Abstract:

Elec-pump (electric-hydraulic-pump) is a highly integrated combination of electric motor and hydraulic pump, which has smaller size, lower noise and vibration, better heat elimination, and has broad application prospects. In this paper, an elaborately parameterized model of the axial piston Elec-pump is built for the mechanical and hydraulic joint simulation by using the simulation software AMESim and ADAMS. The joint model is composed of the electromagnetic drive model, hydraulic model, the mechanical dynamics model and the mechanical hydraulic interface. The joint simulation shows how the rotor centroid pulsation affects the output pressure of Elec-pump at different outlet pressures. The results depicts that, due to the rotor centroid pulsation, the outlet pressure pulsation rate becomes more than doubled at the revolution of 7000rev/min.
