摘　　要：水液压柱塞泵是水液压系统关键元件,现有直线电机驱动的水液压柱塞泵一般都采用单向阀配流,阀配流式柱塞泵存在配流阀响应滞后的问题,为了解决这个问题,提出了一种音圈电机直线驱动水液压往复柱塞泵结构。本文介绍了音圈电机驱动水液压柱塞泵的工作原理,建立了柱塞泵的流量数学模型。应用AMESim软件,构建了仿真模型。仿真结果表明,柱塞间隙为(8~10)μm时,柱塞泵的容积效率约为92%,双音圈电机输入运动信号相位差为3π/2时,柱塞泵的流量脉动最低,平均流量最大。随着柱塞泵两腔无效容积增大,柱塞泵的流量脉动增加。通过分析柱塞泵闭死容积的影响,柱塞阀芯部分配流遮盖量应取0.75mm。Water hydraulic plunger pump is the key component of water hydraulic system.The existing water hydraulic piston pump driven by linear motor generally adopts one-way valve distribution.There is a lag of valve response in the port valve of plunger pump.In order to solve this problems,a structure of water hydraulic reciprocating plunger pump driven by voice coil motor is proposed.This paper introduces the working principle of water hydraulic plunger pump driven by voice coil motor,and establishes the flow mathematical model of the plunger pump.Using AMESim,the simulation model is built.The simulation results show that the volume efficiency of the plunger pump is about 92%when the plunger clearance is(8~10)μm.When the phase difference of the input motion signal of the double voice coil motor is 3π/2,the flow fluctuation of the plunger pump is the lowest and the average flow rate is the largest.With the increase of the invalid volume of the two chambers of the plunger pump,the flow pulsation of the plunger pump increases.Through the analysis of the influence of the dead volume of the plunger pump,the flow coverage of the plunger is 0.75mm.
