摘　　要：针对某锻造操作机液压系统因负载压力不同导致多执行机构不能复合动作的问题,提出一种基于压力补偿原理的多执行器分流方法。利用AMESim建立压力补偿阀模型,并对改进后的液压系统流量分配特性进行仿真分析。结果表明:通过在高频响换向阀前添加二通压力补偿阀,并配合梭阀组形成压力补偿回路,可以使液压系统在负载压力不同的情况下能够实现流量分配,完成锻造操作机多执行机构的复合动作。Aimed at the failure of the forging manipulator hydraulic system of the multi-actuator to com- plete the complex movement due to different levels of loading pressure, a new flow distribution method based on the principle of pressure compensation was proposed. The two-way pressure compensation valve model was established through AMESim and the flow distribution characteristics of the improved hydraulic system was emulationally analyzed. The results showed that the improved system of pressure compensation circuit with a shuttle valve achieved a good flow distribution with different levels of loading pressure and the forging manipulator completed the designed complex movement.
