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.
