基于ANSYS的数控铣床立柱结构分析及参数优化设计

Structure analysis and optimization design in polar of NC milling machine on ANSYS

采用有限元软件ANSYS计算分析了XK713数控铣床(教学型)立柱的变形.利用有限元的参数化设计模块对其结构进行优化设计,运用不同优化工具和步骤对比验证最佳设计结果的可靠性.通过多层优化设计,立柱结构在保证3个方向上刚度合理分配的基础上,质量减轻了12.87%.

Using the structural module of finite element of ANSYS,the deformation ditribution in polar of XK713 NC milling machine the type for teaching was calaulated and analyzed.Then the parameter optimization design model of FEM for the polar is used,and the reliability of the result is proved throught different optimization tools and process.The result showed that about 12.87% of the its weight has been reduced and its stiffness reasonable distribution has been controlled in three dimensions.
