HM-3420: Create Bolt Connectors(HM-3420:创建螺栓连接器)

In this tutorial you will learn how to apply a bolted connection to two rear trusses.(在本教程中，您将学习如何应用螺栓连接到两个后桁架。)

The Bolt panel creates connectors based on holes with in the connected components, using spiders or washers at each end of an RBE connector. When the Bolt panel is active, only bolt-type connectors display in the graphics area; graphics for other connector types are suppressed until you exit the panel. (螺栓面板基于连接组件中的孔创建连接器，使用蜘蛛或垫圈在RBE连接器的每一端。当螺栓面板激活时，只有螺栓类型的连接器显示在图形区;在退出面板之前，其他连接器类型的图形将被抑制。)

The Bolt panel contains three subpanels:
。 Bolt: Create and realize bolt connectors in a single process
。Create: Create, but not realize, bolt connectors
。Realize: Create FE representations of previously-created bolt connectors
（螺栓面板包含三个子面板:_

。创建和实现螺栓连接器在一个单一的过程?

。创建:创建但不实现螺栓连接器

。 实现:创建前面创建的螺栓连接器的FE表示）

This exercise uses the frame_assembly_2.hm file, which can be foundin the hm.zip file. Copy the file from this directory to yourworking directory.

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 clicking onthe Standard toolbar.
  5. In the Open Model dialog, open the frame_assembly_2.hm file.
    A model appears in the graphics area.
  6. Observe the model using various visualization options available (rotation,zooming, and so forth).

Step 2. Display Only the Assembly（步骤2。只显示Assembly）

In this step you will display only the assembly assem_5 forelements and geometry.(在此步骤中，您将只显示程序集assem_5前元素和几何图形。)

  1. In the Model Browser, click (Model View).
  2. Expand the Assembly Hierarchy folder andsub-folders.
  3. Set the entity selection to (Elements andGeometry). (3.设置实体选择为(Elements andGeometry)。)

Note: This option 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_5 and select Isolate from the context menu.
    HyperMesh displays only the components thatare in the assem_5 assembly.
  2. Right-click on the Con_Rear_Truss component and select Make Current from the context menu.

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.(在此步骤中，您将加载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 thereare no components or connectors listed because there are no connectors in themodel. (检查连接器浏览器的布局。目前没有列出组件或连接器，因为模型中没有连接器)

Note: You can use the Connector Browser to view and managethe connectors in your model. The top portion of the browser is referred toas the Link Entity Browser, and it displays information about the linkedentities in your model. The middle portion is referred to as the ConnectorEntity Browser, and it contains a list of the connectors in your model. Thebottom portion of the browser is referred to as the Connector Entity Editor,and it displays attributes assigned to the connector(s) selected in theConnector Entity Browser. HyperMesh groups theconnectors based on their connection type.(**注意:**您可以使用连接器浏览器来查看和管理模型中的连接器。浏览器的顶部被称为链接实体浏览器(Link Entity browser)，它显示关于模型中链接实体的信息。中间部分称为ConnectorEntity Browser，它包含模型中连接器的列表。浏览器的底部部分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。HyperMesh根据连接器的连接类型对它们进行分组。)

Step 4. Create a Bolt Connector(步骤4。创建一个螺栓连接器)

In this step you will create a bolt connector.(在此步骤中，您将创建一个螺栓连接器。)

  1. Open the Bolt panel by right-clicking in the Connector Entity Browser and selecting Create Bolt from the context menu.
  2. Set the location selector to nodes.
  3. Select a node on the edge of the hole in the Rear_Truss_1 component asindicated in the following image.
  4. Set the connect what selector to comps.
  5. Click comps.
  6. Select the components Rear_Truss_1 and Rear_Truss_2.
  7. Click select.
  8. In the tolerance= field, type 50. The connector willconnect any selected entities within this distance. (在公差=字段中，键入50。连接器将连接此距离内的任何选定实体。)
  9. Click type= and select bolt(general). (单击type=并选择螺栓(一般)。)

Note: Re-realizing the connector will allow you to see the different bolt types.(注意:重新实现连接器将允许您查看不同的螺栓类型。)

  1. Click realize & hole detect details.
  2. In the max dimension= field, type 60 to ensure that the diameter of the picked hole will be captured. ( 在max dimension=字段中，键入60，以确保所挖孔的直径将被捕获。)
  3. Click return.
  4. Click create.

Note: Ensure the display of the current component is turned on.(注意:确保当前组件的显示是打开的)

  1. To access the main menu, click return.
