摘　　要：运用Solid Works软件建立了数控高速磨床床身的三维模型,并在Simulation软件模块中对其分别进行了静力学和模态分析,根据分析结果,对床身筋板的布局、壁厚以及掏沙孔形状等不合理结构进行优化。优化后的床身经过有限元分析后,其最大应力可以减少20.63%,最大变形量可以减少22.18%,第一阶固有频率可以提高9.40%,总体质量可以减少10.48%。This paper uses Solid Works software to establish a three-dimensional model for CNC high-speed grinding bed,and its static and modal analysis are carried out in the simulation software modules.According to the results,the unreasonable structures of the bed are optimized,including the layout and thickness of the ribs,the shape of dig sand holes.The bed is optimized using the finite element analysis,the maximum stress can be reduced 20.63%,the maximum amount of deformation can be reduced 22.18%,the first natural frequency can be raised 9.40%,the overall mass can be reduced10.48%.
