摘　　要：研究运用结构优化设计方法对锚链轮进行轻量化设计的流程和效果。以正多边形啮合的五齿锚链轮为研究对象,利用SolidWorks软件构建锚链轮三维模型;基于ANSYS Workbench软件对锚链轮进行瞬态动力学分析和模态分析;以锚链轮的轮毂和两侧壁厚度为设计变量,以最大应力为约束条件,以最小化质量和一阶固有频率为优化目标,构建锚链轮结构优化数学模型;基于多目标遗传算法对锚链轮的尺寸进行优化,得到3组最优解集,并通过瞬态分析得到锚链轮的最大弹性变形量,确定基于最优解集的最终优化结构。研究结果表明,采用该方法优化之后,锚链轮的质量减少3.25%,刚度和强度均有所提高。该轻量化设计流程和方法可供其他船舶辅机设备的轻量化设计参考。The process and results of structure optimization design method is studied for the lightweight design of anchor sprocket,where a regular polygon five-tooth anchor sprocket is taken as the object to create 3 D model of anchor sprocket with SolidWorks software and the transient dynamic analysis and modal analysis are based on ANSYS Workbench.Then the optimization mathematical model of the anchor sprocket structure is established with the thickness of anchor sprocket hub and the two side walls as design variables,the maximum stress as constraint and the minimized mass and first-order natural frequency as the optimization objectives.The size of anchor sprocket is optimized according to the multi-objective genetic algorithm to obtain three optimal solutions.The maximum elastic deformation of anchor sprocket is obtained by transient analysis,and the final optimized structure is determined with the three optimal solutions.The results show that the mass of anchor sprocket is reduced by 3.25%and the stiffness and strength are improved after optimization.The process and method of lightweight design may provide important reference for the lightweight design of auxiliary equipment on other ships.
