摘　　要：将传统电液比例排量泵变量机构的位移-力反馈结构改进为位移-电反馈式结构,改善了比例排量泵的可控制性能。通过分析其简化系统模型,建立动态特性方程,并利用SIMULINK软件进行仿真,结果表明改进后其系统动态性能好。The displacement-force feedback structure of the variable mechanism of conventional electro-hydraulic pump was rebuilt by displacement-electro feedback structure,which improved the controllability of the pump.The simplified system model of the pump was analyzed,the dynamical equation of state was built and simulated by SIMULINK.The result shows that the improved pump has good dynamic characteristics.

关 键 词：电液比例泵 位移-电反馈 仿真
