ANSYS APDL学习(3)：ANSYS APDL 导入x_t格式模型并受力分析范例

第一步：导入模型

打开ansys APDL，点击“File” ->”Import”->”PARA”

选择 x_t 格式，选择现成的x_t格式文件，然后点击“OK”

然后就会看到导入的模型

先点击“PlotCtrls”->”Numbering”

将 关键点KP, 线LINE，面AREA,体VOLU，结点NODE的编号全部打开，如果后期不需要可以再点击使它关闭。

然后点击右边栏的 “dynamic model mode“动态模型模式，点击后，右键长按且移动鼠标是转动物体。左键长按且移动鼠标是平移物体。将物体平移转动到一个合适的位置，看图上的编号，发现体积V1，面A1_A6,线L1L12，关键点1~8都有，说明以x_t模式成功导入的点、线、面和体。这样体是透明的不要紧，在等等划分网格时候就会自动地出现默认颜色。

第二步：设置单元类型

先定义单元类型，这里将导入的模型定义成体
选择“Preprocessor“->”Element Type”->”Add/Edit/Delete”->”Add”,选择 solid -> 20 node 186 -> OK,
最后将”Element Type” 窗口关闭

第三步：划分网格

在左边栏，选择 “Preprocessor“->”meshing”->”mesh”->”Volumes”->”free”，随意划分一个网格尝试一下。

会跳出弹窗和警告，点击“close“

然后鼠标选中这个模型，意思是准备将这个体进行网格划分。

然后点击OK

第四步：材料属性

在左边栏Preprocessor -> Material Props -> Material Models 中，选择 Density 密度填写7800，选择OK

在Linear Isotropic 中填写 E=2e11，PRXY=0.26，然后点击OK

第五步：施加位移约束和力

给模型施加位移约束：选择 Solution->Define Loads -> Apply ->Displacement-> On Areas ,然后点击图中选中的面，最后点击OK

选择所有自由度 All DOF，然后点击OK

然后给面施加压强，选择 Solution->Define Loads -> Apply ->Pressure-> On Areas ,选中面，然后点击OK

输入压强的数值，然后点击OK

第七步：计算

开始计算，选中 Solution->Solve->Current LS,然后点击OK

计算结束

施加位移约束和载荷后的模型是这样的

第八步：查看结果

查看变形结果，General Postpro -> plot results -> deformed Shape, 选择def+undef edge，就是选择变形前后的轮廓都要同时显示

这是关掉刚刚开启的numbering编号后，看到的变形前后的差异。

查看每一点的位移变化
选择 General Postproc -> List Results -> Nodal Solution 选择 Nodal Solution -> Displacement vector sum ，然后点击OK

每个点的位移变化如下
