HM-3400教程：Create Connectors创建连接器方法

HM-3400: Create Connectors（HM-3400:创建连接器）

In this tutorial you will learn how to weld two front trusses by creating connectorsbetween geometry surfaces at pre-defined weld points.（在本教程中，您将学习如何通过在预定义的焊接点创建几何表面之间的连接器来焊接两个前桁架）

You will learn how to:?Weld the two front trusses to each other by creating connectors at pre-definedweld points

   ?Weld the two front trusses to the reinforcement plate by creating connectorsbetween shell elements

   ?Weld the right rails to each other and to the front trusses by creatingconnectors from a master connectors file

   ?Update weld type   of Nastran/OptiStruct ACM (area contact method) welds, which alreadyconnect the rear trusses to each other, by first creating connectors from thesewelds and then realizing the connectors into two-noded weld elements

This exercise uses the frame_assembly.hm file, which can be found inthe hm.zip file. Copy the file from this directory to your workingdirectory.

   （将学习如何:?通过在预定义的焊接点创建连接器，将两个前桁架相互焊接

通过在壳体单元之间创建连接器，将两个前桁架焊接到加固板上

从主连接器文件中创建连接器，将正确的轨道相互焊接，并与前面的桁架焊接

更新 Nastran /OptiStruct ACM(区域接触法)焊缝的焊接类型，这些焊缝已经连接了后面的桁架，首先从这些焊缝中创建连接器，然后将连接器实现为两个节点的焊接元素

本练习使用frame_assembly。可以在Hm .zip文件中找到。将该文件从此目录复制到您的工作目录。）

Step 1. Open the Model File

In this step you will open and view the model file.

1. Start HyperMesh Desktop.
2. In the User Profile dialog, select OptiStruct.
3. Click OK.
4. Open a model file by clicking File > Open > Model from the menu bar, or click on the Standard toolbar.
5. In the Open Model dialog, open the frame_assembly.hm file. A model appears in the graphics area.
6. On the Visualization toolbar, click toshade your model’s geometry and surface edges.
7. Observe the model using various visualization options available, such asrotation and zooming.

step 2. Display   Only the Assembly

In this step you will display only the assembly assem_1 forelements and geometry.

1. In the Model Browser, click (Model View).
2. Expand the Assembly Hierarchy folder andsub-folders.
3. Set the entity selection to (Elements and Geometry).

Note: This options turns on/off both elements and geometry when you performright-click operations in the Model Browser.(注意:当您在Model Browser中执行右键操作时，此选项将打开/关闭元素和几何图形)

1. Right-click on assem_1 and select Isolate from the context menu.
   
       The components that are in the assem_1 assemblyare displayed.

Step 3. Load the Connector Browser(步骤3。加载连接器浏览器)

In this step you will load the Connector Browser.

1. Open the Connector Browser by clicking View > Browsers > HyperMesh > Connector from the menu bar.
2. Review the layout of the Connector Browser. Currently,there are no components or connectors listed because there are no connectors inthe model.

: Use the Connector Browser to view and manageconnectors. The top portion of the browser is referred to as the Link EntityBrowser, and it displays information about linked entities. The middleportion is referred to as the Connector Entity Browser, and it contains alist of the connectors in your model. The bottom portion of the browser isreferred to as the Connector Entity Editor, and it displays attributesassigned to the connector(s) selected in the Connector Entity Browser. Theconnectors are grouped based on their connection type.(注意:使用连接器浏览器来查看和管理连接器。浏览器的顶部被称为Link EntityBrowser，它显示有关链接实体的信息。中间部分称为连接器实体浏览器，它包含模型中的连接器列表。浏览器的底部被称为连接器实体编辑器，它显示分配给在连接器实体浏览器中选择的连接器的属性。连接器根据其连接类型进行分组。)

Step 4. Create Welds between Geometry（创建几何之间的焊接）

In this step you will create welds between geometry for the two front trusses at thepre-defined weld points.（在这一步中，您将在预定义的焊接点为两个前桁架几何之间创建焊接。）

Connectors can be created automatically or manually. The automatic approach createsand realizes connectors automatically. The manual approach allows you to
