讨论了一种可用于高性能大流量控制的插装式伺服比例阀。通过分析该阀的结构原理，推导了该阀的传递函数。利用该传递函数，研究了影响其性能的一些结构因素。通过数值模拟和试验研究，提出了改善该阀动态性能的一些优化原则和有效方法。试验结果与理论分析和仿真结果相吻合，证明了研究和仿真工作的正确性，为工程应用和系列化扩展设计工作提供了理论依据。
A kind of cartridge servo proportional valve is discussed,which can be used for controlling large flow rate with high performance.By analyzing the structure principle of the valve,the transfer function of the valve is derived.With the transfer function,some structure elements that may affect its performance are investigated.Through the numerical simulation and test study,some principles of optimality and effective methods for improving the dynamic performance of the valve are proposed. The test results conform to the results of the theoretical analysis and simulation,which proves the correctness of the study and simulation works.The paper provides theoretical basis for engineering applications and series expanding design works.
