摘　　要：为了最大限度地提升泡沫铝填充结构机床工作台的轻质性和静、动态性能,对前期设计的该结构工作台进行优化设计。优化设计过程中设定工作台的总体质量最小为目标函数,铸铁层外壳的厚度尺寸为优化变量,工作台的最大应力和最大变形量为约束条件。然后对优化前后的泡沫铝填充结构机床工作台的静、动态特性进行有限元仿真分析,对其质量进行计算,并将两种结构工作台的静、动态特性和质量进行比较。结果表明,优化后的泡沫铝填充结构机床工作台的轻质性和高静、动态性能更显突出。In order to reduce the mass and improve the static and dynamic properties of the machine tool table filled with foam aluminum, the preliminary worktable designed before was optimized. The total mass of the machine tool table was set as objective function, the thickness of cast iron layer casing as variables, the maximum stress and deformation as constraints. Then finite element analysis was used to optimize the static and dynamic properties of the machine tool table, the mass was calculated and a contrast before and after optimization was made. The results show that the optimized machine tool table filled with foam aluminum is lighter in mass and better in static and dynamic performance than the previous one.
