摘　　要：为探索提高机床综合性能的新途径,提出了泡沫铝夹芯结构立柱新构型。首先,选取XK714数控机床立柱为原型,运用等刚度设计理论和轻质性设计理论初步设计泡沫铝夹芯结构机床立柱;然后,运用多目标优化设计的方法对泡沫铝夹芯结构机床立柱进行优化设计;最后,对原型立柱和优化前后的泡沫铝夹芯结构立柱的静、动、热态性能及轻质性进行对比分析。结果证明:泡沫铝夹芯结构机床立柱在提高机床立柱乃至整机的静、动、热态性能及轻质性方面的有效性。In order to explore a new way to improve the comprehensive performance of machine tools,a new configuration of foam aluminum sandwich structural column is proposed.Firstly,the XK714 CNC machine tool column is selected as the prototype,and the foam aluminum sandwich structure machine tool column is preliminarily designed with the equal rigidity design theory and the light weight design theory.Then,the multi-objective optimization design method is used to optimize the design of foam aluminum sandwich structure machine tool columns.Finally,the static,dynamic,thermal and light properties of the prototype column and the foam aluminum sandwich structure column before and after optimization are compared and analyzed.The results show that the foam aluminum sandwich structure machine tool column is effective for improving the static,dynamic,thermal and lightweight performance of the machine tool column and even the whole machine.
