基于Hypermesh的立式加工中心立柱结构的拓扑优化

摘要

立柱是立式加工中心影响加工精度和结构特性的关键部位，它的固有频率等动力学特性对整机特性影响非常大。通过有限元分析软件HyperWorks中优化模块OptiStruct对GSVM6540L2机床立柱进行单目标拓扑优化和多目标拓扑优化，并根据优化结果和经验对立柱进行了改进，提高了立柱的静动态特性和整机的静动态特性。%Column,as a key component in vertical machining center,affects machining accuracy and structural properties,whose dynamic characteristics like natural frequency have large impact on the whole machine fea-tures. In this paper,single-objective and multi-objective topology optimization have been conducted on the column of GSVM6540L2 vertical machining center by the module OptiStruct in the finite element analysis soft-ware HyperWorks. According to the optimization results and experience,the static and dynamic characteristics of the column and the whole machine are improved.
