摘　　要：磨齿机立柱动静刚度直接影响机床的加工质量。针对现有立柱动静刚度薄弱的问题,分析立柱壁厚、筋板厚度和高度、后窗口尺寸及双层筋板对立柱结构特征频率的灵敏度,找出对该类型立柱结构动态特性影响较大的设计参数。通过优化敏感设计参数,重新构建立柱模型。仿真结果表明:与原立柱相比,优化后立柱结构的动静刚度特性得到显著改善。The dynamic and static stiffness of column of grinding machine tools indirectly affect processing quality of machine tools. Considering the problem of weak stiffness on the column, the sensitivity analyses of wall thickness, rib thickness and height, window size and double rib for the column structure frequencies were made in order to find which design parameters had larger influence on dynamic characteristics. The column was rebuilt through optimizing the sensitive parameters. The simulation results show that optimized column has better dynamic and static properties than the original one.

关 键 词：立柱 灵敏度 动态特性 优化设计
