Research on High Power Direct Drive Differential Volume Control Electro-Hydraulic Servo System

摘要

For traditional direct drive volume control electro-hydraulic servo system, the servo motor's rotary inertia is limited strictly, the speed of response is slow and the actuator's reciprocating motion characteristics are not consistent. In order to solve these problems, this paper designs a kind of high power direct drive differential volume control electro-hydraulic servo system. It is instructive for design of hydraulic system which demands high output power, changes direction of motion frequently, needs high response frequency and requires the speed of reciprocating motion keep consistent.
