摘　　要：闭式液体静压导轨是高精密车床的重要元件,用Solidworks建立精密机床导轨的关键零部件的实体模型,并且利用Workbench对其进行了有限元分析,其中包括静态性能分析和模态分析。静态性能分析得到导轨零件在工作状态下的受力变形云图和应力分布云图,获得零件的最大变形量和最大应力值;模态分析得到了导轨零件各阶的固有频率和振型,分析结果显示各个导轨零件的各阶固有频率均远远大于机床工作的固有频率,能有效避免"共振"现象的发生,能有效满足机床的使用要求。The closed hydrostatic guideway is an important component for high-precision lathe. The models of its key parts are established by using Solidworks software, and the finite element analysis, including static analysis and modal analysis are obtained by using Workbench. In addition, maximum deformation and stress value are got from deformation map and stress distribution map under working condition during static analysis, and natural frequency and vibration mode are obtained during modal analysis. What is more, natural freqnency of these key parts is significantly larger than the one during lathe working, and therefore resonance will not happen and they satisfy the demands for lathe.
