摘　　要：基于ANSYS Workbench平台,以某数控立式车床回转工作台为研究对象,利用拓扑优化和尺寸优化设计方法,对其进行了以减轻质量和提高结构刚度为目标的结构优化设计研究。分析结果表明:与原设计方案相比较,优化改进后的回转工作台质量减少了24.97%,最大变形量减小了39.8%,而且一阶固有频率也由399.9 Hz提高到474.9 Hz。Using topological optimization and size optimization design method,structural optimization design for the rotary worktable of vertical lathe is proposed based on ANSYS Workbench in order to reduce its weight and improve the structural stiffness. The analysis results indicate that the weight of the improved rotary worktable is decreased by 24. 97%,and the maximum deformation is reduced by 39. 8%,and the first order natural frequency is increased from 399. 9Hz to 474. 9Hz compared with the original design.
