摘　　要：以某专用磨床主轴箱为研究对象,采用Solidworks建立主轴箱的参数化模型,利用Workbench对主轴箱原模型进行静力分析和模态分析。根据分析结果初选12个尺寸参数作为设计变量,并对其进行灵敏度分析,筛选出对主轴箱主轴孔部位变形影响最大的六个参数。在此基础上进行多参数多目标优化,并对优化结果予以校验。最终实现在保证主轴箱静动态特性的前提下,降低主轴箱质量,提高优化效率。The headstock of a special grinder is taken as the object of study.The parameter model of the headstock is established by three-dimensional modeling software Solidworks.And it is transmitted to ANSYS Workbench for finite element analysis.With static analysis and modal analysis of original model of headstock,12 design parameters are selected to implement sensitivity analysis.Eventually 6design parameter have great influence on the deformation of spindle hole.Based on sensitivity analysis,multi-objective and multi-parameter optimization is taken.Then the static analysis and modal analysis of modified model is taken to check optimization results.Finally the mass of headstock reduce and optimization efficiency is improved,while the static and dynamic characteristics are guaranteed.
