摘　　要：液压舱口盖在承受集装箱载荷和风雨载荷过程中起着非常关键的作用。根据液压舱口盖的受力与变形特点,将优化理论应用于液压舱口盖结构优化设计中,建立了液压舱口盖结构优化模型。以液压舱口盖结构重量为目标函数,优化过程中考虑了强度、刚度和屈曲等多种约束工况。在多种载荷作用下,优化了液压舱口盖结构,使优化后的液压舱口盖结构不但满足强度和刚度衡准要求,同时也满足屈曲强度要求。The hydraulic hatch cover plays very important roles in container and weather loads. According to stress and deformation characteristics of hydraulic hatch cover, the method of optimization theory based on dual method was transplanted to optimize hatch cover structure, and the optimizing model of hatch cover structure was established.The target function is the structure gravity of hatch cover.There are three kinds of constraints： yielding strength, rigidity and buckling strength. The hydraulic hatch cover was optimized under multiple loads, the numerical calculation results show that the yielding strength and buckling are fit.
