Pressure Control Characteristics Simulation Research of Electro-Hydraulic Proportional Variable Pump
Based on the theoretical analysis on working principle and motion of the electro-hydraulic proportional variable piston pump, it created and simulated the model in the AMESIM software. The influences of main structural parameters of variable pump on system output dynamic characteristics were revealed after simulating analysis results of pressure control characteristics. And the steady state output of system pressure is proportional to the input voltage of amplifier. The overshoot decreases with the increasing of input voltage, and the response get faster. The damping aperture of proportional reversing valve and core diameter of control plunger have a greater influence on the dynamic response of system.
