摘　　要：以长江船闸液压启闭机液压系统为对象进行研究,利用AMESim软件搭建该液压启闭机液压平衡回路仿真模型,并对整个船闸开启过程和关闭过程中插装式平衡阀内主阀芯弹簧刚度等主要参数进行单因素仿真。利用统计学分析这些单因素参数对长江船闸液压启闭机液压系统稳定性的影响。基于L_(25)(5^(4))正交试验,采用方差和极差分析法处理液压缸运行的压力曲线,得到选择范围内最佳的参数组合。结果表明:平衡阀内控制阻尼孔和主阀芯刚度等主要参数对液压缸运行压力和速度平稳性会产生重要影响,且通过正交试验可知较优参数组合为:阻尼孔尺寸0.71 mm,主阀芯弹簧刚度402 N/mm,主阀芯弹簧预紧力60 N,单向阀芯弹簧刚度3.87 N/mm。为螺纹插装式平衡阀的设计及液压启闭机液压系统参数优化提供指导。The cartridge balance valve in hydraulic hoist hydraulic system of Yangtze river shiplock is studied and analyzed,the simulation model of the hydraulic balance loop of the hydraulic hoist was built by AMESim software,and the single factor simulation is carried out for the main parameters such as stiffness of core reading projectile in the cartridge balance value during the whole opening and closing process of the shiplock.The influence of these single-factor parameters on stability of the hydraulic hoist Yangtze river shiplock was statistically analyzed.Based on the L_(25)(5^(4))quadrature test,the pressure change curve of the hydraulic cylinder operation is processed by the variance and range analysis methods,and the optimal combination of parameters in the selected range can be obtained.The results show that the main parameters such as the control damping hole and the main spool stiffness in the balance valve have an important impact on the operating pressure and speed stability of the hydraulic cylinder,and through the orthogonal test,it can be seen that the preferred parameter combination is damping hole size of 0.71 mm,the main spool spring stiffness of 402 N/mm,the main spool spring preload force of 60 N,and the one-way spool spring stiffness of 3.87 N/mm,which provides guidance for the design of threaded plug-in balance valve and the optimization of the hydraulic system parameters of the hydraulic hoist.
