摘　　要：为提升液压起重系统的动态性能,以某款液压平衡阀为核心元件,分析其3种工作状态,设计一个泵阀协同控制的液压起重系统,利用AMESim-Simulink搭建平衡阀以及液压起重回路模型。仿真结果表明:平衡阀控制的液压起重系统处于小流量、小负载工况下时,其负载由静止到下降的过程中会出现速度峰值高、速度稳定慢的问题;相比仅有平衡阀控制的液压起重系统,基于模糊PID的泵阀协同控制的液压起重系统在小流量、小负载工况下的速度超调更小,速度稳定时间更短。To improve the dynamic performance of hydraulic lifting system,a hydraulic balance valve was used as the core component to analyze its three working states.A hydraulic lifting system with pump valve collaborative control was designed,and a balance valve and hydraulic lifting circuit model were built using AMESim-Simulink.The simulation results show that when the hydraulic lifting system controlled by the balance valve is in a small flow and small load condition,the transition process from static to descending of the load results in large speed peak and slow speed stability.Compared with the hydraulic lifting system only controlled by the balance valve,the hydraulic lifting system based on fuzzy PID pump valve collaborative control has smaller speed overshoot and shorter speed stability time under small flow and small load conditions.
