摘　　要：在建立四通阀控对称液压缸动态数学模型的基础上,利用matlab中的simulink工具软件建立系统柔性仿真模型,并对其动态特性进行数字仿真研究。得到相关参数的变化对系统性能的定量影响,为该类系统的设计提供快速分析手段,并可确定原点附近使系统动态性能达到较好的一组参数值。the models of dynamic characteristics of symmetrical cylinder controlled by symmetric four-way valve were established. The flexible simulation model was also constructed by the use of MATLAB. The model＇ s dynamic characteristics were stimulated. Slide flux gain, flux - pressure coefficient and damp coefficient which make the system in best performance were finally obtained by contrasting different parameters which affect system performance.
