摘　　要：以压力流量功率复合控制泵的功率控制部分为研究对象,利用AMESim搭建压力流量功率复合控制泵的整体仿真模型,针对影响其功率控制部分动静态特性的几个关键因素——流量阀弹簧刚度、功率阀阀芯三角槽数进行变参分析。仿真结果表明:增大流量阀弹簧刚度,可以改善功率控制范围内斜盘摆角的动态特性;增加功率阀阀芯三角槽个数,可以减小最小功率值,从一定程度上增大功率控制范围。The power-control part of pressure/flow/power control pump as the study object, the model of the pump was complete- ly built in AMESim for simulation. Altering-parameter analysis was performed for several key factors that influence the dynamic and static characteristics of the power-control part of the pump, such as spring stiffness of flow-rate valve and the number of the triangular grooves of the power valve spool. The simulation results show that the dynamic and static characteristics of the swash-plate angle in range of power-control are improved by increasing the spring stiffness of flow-rate valve; the minimum power value is reduced and the range of power control is broadened to a certain extent by increasing the number of the triangular grooves of the power valve spool.
