摘要：
The hydraulic driving source plays an important role in the performance of the electro-hydraulic robot. In this paper, the Lumped parameter method is used to establish the pressure-flow characteristic model of the constant pressure variable pump of a 6-DOF electro-hydraulic robot, and attain the influencing factors of the flow pulsation. The simulation model of the electro-hydraulic robot is established, which is used to study the oil property and plunger leakage characteristics of the constant pressure variable pump on the affection of the flow pulsation. The experimental results display that the elastic pulsation is the main form of the output flow pulsation of the constant pressure variable pump, and the pulsation rate will increase with the load quantity of the robot.
