摘　　要：为了提高动梁龙门加工中心整机的动静刚度,利用仿生学原理,立柱采用了蜂窝结构设计。通过有限元对比分析,蜂窝结构立柱的抗扭和抗压性能均优于传统立柱,蜂窝立柱不仅增强了立柱和整机刚性,而且降低了立柱铸造的残余应力,大大提高了机床的动静态性能。In order to improve the dynamic and static stiffness of the bridge moving gantry machining center,using the principle of bionics,the column is designed to honeycomb structure.Through the finite element analysis,the property of the honeycomb structure column to resist press and torque distortion is better than traditional column.The honeycomb structure column can not only improve the rigidity of the column and the whole machine,but also reduce the residual stress of the column casting,greatly improve the dynamic and static performance of the machine.
