摘　　要：通过建立轴向柱塞变量泵总功率控制的数学模型,并利用Matlab进行仿真计算,得到单泵负载压力变化时变量泵的压力-流量曲线,可知单泵负载压力变化时,两个变量泵的流量变化与负载压力在载荷柱塞上的作用面积大小有关,为变量泵总功率控制的设计提供了一定的参考。By establishing the mathematical model of the total power control of the axial piston variable pump,and using the simulation calculation by Matlab,the pressure flow curve of the variable pump is obtained when the load pressure of the single pump is changed. It is known that when the single pump loads pressure changes,the flow change of the two variable pump is connected with the area of the load plunger which the load pressure effectes. It provides a reference for the design of variable pump total power control.
