用SolidWorks软件建立龙门加工中心工作台3种三维实体模型，按照分析方案的设计，分别导入到ANSYS Workbench中进行静力学分析，得到井字形筋工作台的平均复合静刚度比O形筋和椭圆形筋工作台分别高18．68％和11．85％，并且井字形筋工作台的质量分别减轻10．14 kg和14．11 kg ，但是静刚度标准差分别高23．1％和12．46％．最后，用M A T‐LAB软件绘制了三种不同工作台的复合静刚度图谱．根据图谱，可将工件装夹于合适位置，减小了工件加工时工作台的静变形，提高了其加工精度．

Three different 3D solid models of gantry machining center worktable were set up by SolidWorks ,according to design of the analysis scheme ,then imported into the ANSYS Workbench for static analysis separately .The average composite static stiffness was higher 18 .68% and 11 .85% than worktable with O‐shaped and ellipse‐shaped rib plate ,and the mass of worktable with well‐shaped rib plate was reduced 10 .14 kg and 14 .11 kg than the two others ,however ,standard deviation of the static stiffness was higher 23 .1% and 12 .46%compared with worktable with O‐shaped and ellipse‐shaped rib plate .Finally ,composite stat‐ic stiffness maps of 3 different worktables were created by MATLAB .According to the map , the workpiece could be clamped to a suitable position ,the static deformation of worktable de‐creased ,the machining accuracy of workpiece improved .
