摘　　要：为了解决传统机床设计过程中存在设计周期长、刚度不足和结构笨重等缺陷。文章依据VL1060立式加工中心床身的结构特点,运用有限元法对床身进行动静态分析和结构优化,在满足机床强度的前提下,进行关键设计尺寸的灵敏度分析,对床身性能影响较大的尺寸进行优化取值,选择最佳优化方案。优化结果表明,运用此方法优化后,减轻了床身的重量,床身的刚度和固有频率均有所提高,为以后加工中心床身的设计提供了指导。In order to solve the problem of long design period, insufficient stiffness, heavy structure and other defects in the process of the traditional machine tool design. According to the structure features of the VL1060 vertical machine center, finite element method was used for the static and dynamic analysis and structure optimization of MC bed. Premise to meet intensity of machine, analysis of sensitivity of the key design dimensions. To choose the best optimization scheme by select the dimensions which had most influ-ence on the MC bed. It＇s proved that the weight of the optimized bed is reduced^ the stiffness and natural frequency were enhanced, providing reference for future structural design of MC bed.
