| 摘 要： | 以MM52160导轨磨床立柱为研究对象,首先采用Spaceclaim软件建立龙门导轨磨床立柱的三维实体模型,并利用Hypermesh有限元软件对该模型进行前处理,建立立柱的有限元模型。对该有限元模型进行动静态特性分析,然后以立柱的质量作为目标函数,最大变形量作为约束函数,选择对立柱性能影响较大的灵敏度尺寸作为优化设计变量,进行多目标尺寸优化。优化后立柱的整体质量减少了113.2 kg,减少量约为总质量的7.3%;最大变形量减小了2.833μm,减小量约为总变形量的10.7%。实现了在保证立柱刚度的前提下,立柱的质量和最大变形量降低的目的。

| Abstract: | A three-dimensional entity model of the gantry rail grinder column was established by spaceclaim software and pretreated by Hypermesh finite element software, the finite element model of the main column was established. Then, the static analysis and modal analysis were carried out to the established finite element model of the main column, after which we can obtained the stress and deformation of the column and natural frequencies and vibration mode of the former sixth-order. Our research provided a basis for the optimization and improvement of the column and the whole grinding machine. |
