摘　　要：为提高矢量喷管电液伺服系统频宽的策略,以阀控缸为研究对象,分析影响系统频宽的因素。建立了阀控缸系统的数学模型,通过MATLAB仿真计算系统的理论频宽。为研究过度容积对阀控缸频宽的影响,建立了矢量喷管电液伺服系统的AMESim仿真模型。结果表明:应用分布参数管路模型分析,系统频宽与总压缩容积并非严格单调关系,存在一最佳过渡容积112 cm3,使系统频宽达到最大。In order to find the strategy for increasing frequency width of vectoring nozzle electro-hydraulic servo system,the factors influencing the frequency width of the valve controlling cylinder are analysed.The mathematical model of the valve controlling cylinder system is built.The theory frequency width is calculated by using MATLAB.For researching the effect of excessive volume on the frequency width of the valve controlling cylinder,the AMESim model of the vectoring nozzle electro-hydraulic servo system is set up.The simulation results show that the system frequency width and compress volume are not a strict monotonic relation based on the distributed parameter pipe model,and there is a best excessive volume 112 cm^3 that makes the system frequency width being maximum.
