摘要
详细分析二通插装阀的数学模型,建立其流量与进出口压差之间的关系,利用AMESim中的Hydraulic Component Design(HCD)库搭建二通插装阀的仿真模型。根据无导数的Nelder-Mead单纯形优化算法理论,借助Matlab对模型的结构参数进行优化。采用优化结果仿真得到的流量-压降特性曲线与期望特性曲线相当接近,验证了仿真模型的准确性和优化方法的有效性。
Based on mathematical model of cartridge valve, the relationship of flow rate and differences between import and export was established. The simulation model of cartridge valve was built using hydraulic component design （HCD） library in AMESim. The structural parameters were optimized by Matlab according to the no-derivative theory of Nelder-Mead simplex method. By comparing the optimized characteristic curve of flow rate-pressure drop with expectation, the result show that the model is accurate and the optimization is valid.
