摘　　要：海水液压由于具有清洁、结构简单、运行成本低、难燃等优点,已在国内外的海洋装备中得到了广泛应用。但由于海水具有高弹性模量、低黏度的特点,使得海水液压溢流阀存在比较严重的冲击振动问题。针对该问题,建立了一种直动式海水溢流阀的数学模型并进行了仿真分析。鉴于阻尼杆和阻尼套的有效配合长度和间隙是影响直动式海水溢流阀响应特性的关键因素,采用基于ITAE性能指标的遗传算法对其进行优化,得到了阻尼套与阻尼杆的最优配合参数。Seawater hydraulics have been widely used in domestic and international ocean equipment because of its advantages of cleanliness, simpleness of system composition, low operating cost, nonflammability. However, because of the high elasticity modulus and low viscosity of seawater, there is serious vibration in seawater hydraulic relief valve. In order to solve this problem, the mathematic model of a designed seawater direct acting relief valve has established and related dynamic characteristics simulations have been done in this paper. Considering that the effective fitting length and gap between the damping sleeve and damping rod are the key parameters influencing the dynamic characteristics of the valve, we optimze these parameters by using genetic algorithm based on ITAE index.
