摘　　要：为了提高变载输出回路系统位置控制精度,设计了非对称泵控变载输出回路系统。该系统将非对称泵与差动缸进回油流量匹配,实现对执行机构速度或位置控制,并基于AMESim平台展开仿真分析。研究结果表明,空载下,泵控变载输出回路系统在1台泵条件下调节差动缸运行状态,响应速度快;加载下,差动缸位移快速响应,流量与压力发生缓慢变化,具有优良的动态性能。非对称柱塞泵平衡了差动缸的不平衡流量,具有很好发展前景。In order to improve the position control accuracy of variable load output loop system,an asymmetric pump-controlled variable load output loop system is designed.The asymmetric pump of the system is matched with the oil flow of the differential cylinder to realize the speed or position control of the actuator.And based on AMESim platform to carry out simulation analysis.The results show that under no load,the pump-controlled variable load output loop system regulates the diferential cylinder operation state under the condition of one pump with fast response speed.Under loading,the diferential cylinder displacement responds quickly,and the flow rate and pressure change slowly,with excellent dynamic performance.The asymmetric piston pump balances the unbalanced flow of the differential cylinder,which has a good development prospect.
