31、elingOperateBooleansAddVolumes命令，将所有的实体合并为一个整体。建模后，就对模型进行网格的划分，实行Main MenuPreprocessorMeshingMeshTool,先对网格尺寸进行编辑，选0.1，然后点Meshing，Pick all进行网格划分，所得结果如图1.1。划分网格后，就可以对模型施加约束并进行加载求解了。施加约束时要注意，由于三维托架只是通过两个孔进行固定，故施加约束应该只是针对两孔的内外表，执行Main MenuSolutionDefine LoadsApplyStructrualDisplacementSymmetry B.COn Are

32、as命令，然后拾取两孔的内外表，单击OK就行了。施加约束后，就可以对实体进行加载求解了，载荷是施加在三维托架的最顶上的外表的，加载后求解运算，托架的变形图如图1.2。图1.1、托架网格图图1.2输出的是原型托架和施加载荷后托架变形图的比照，虚线局部即为托架的原型，从图1.2可看出，由于载荷的作用，托架上面板明显变形了，变形最严重的就是红色局部，这是因为其离托板就远，没有任何物体与其分担载荷，故其较容易变形甚至折断。这是我们在应用托架的时候应当注意的。图1.2、托架位移变形图图1.3为托架的应力分布图，由图可看出主要在两孔处出现应力集中，也就是说这些地方所受的应力的最大的，比拟容易出现裂痕。我们

33、在应用托架的时候，应当注意采取一些设施，以便减缓其应力集中。特别是在施加载荷时，绝对不能够超过托架所能承受的极限，否那么必将导致事故的发生。文后附上建模分析时所执行的命令流。图1.3、托架应力分布图1.指定分析标题1选取菜单路径Utility Menu | File | Change Jobname，将弹出Change Jobname (修改文件名)对话框。2在Enter new jobname (输入新文件名)文本框中输入文字“bracket，为本分析实例的数据库文件名。单击对话框中的“OK按钮，完成文件名的修改。3选取菜单路径Utility Menu | File | Change Tit
