摘　　要：伺服阀非线性特性是影响液压系统动态性能的重要因素.通过对伺服阀非线性特性的分析,建立了相应的数学模型,并将其应用于工程实践中,建立了基于伺服阀非线性特性的液压弯辊系统的动态分析模型,利用软件MATLAB的工具箱SIMULINK实现了系统的动态仿真,得到较为满意的结果.Nonlinear characteristic of servo value is the important factor influencing hydraulic system, the model of electro-hydraulic servo pressure control system is designed. In this model, flux-equation of servo valve is specially applied and some non-linear characteristics are considered. Furthermore, SIMULINK toolbox of MATLAB language software is applied to solve mathematic model and simulation curves of some variables are obtained. The calculation results are in good agreement with the experimental results.
