Activity 3: Apply constraints and loads

In this activity, you specify a design conditions by applying constraints and loads to the selected geometry. You create three different load cases. You clone a load case and modify an existing load.

Prerequisites

Activity 2 is complete.

Steps

Apply a fixed constraint to the bottom faces of the Bolt Flange components.
1. To hide the plate on the canvas, in the Browser, click next to the Plate component.
2. To change the current view, click the bottom-right corner of the ViewCube.
3. On the Define tab, click Design Conditions > Structural Constraints .
  
  Warning: You can apply constraints to preserve geometries only.
4. In the Structural Constraints dialog, verify that Fixed constraint is selected.
5. On the canvas, select the faces highlighted in blue as shown in the following image.
  
  Note: The padlock icons display on the selected faces.
6. In the Structural Constraints dialog, click OK.
7. To verify that the constraint is applied correctly, in the Browser, expand Load Case1 > Constraints.
  
  Tip: To modify the applied constraint, do one of the following:
  - Mouse over it in the browser, and then click .
  - On the canvas, double-click the padlock icon.
8. To return to the Home view, move the cursor over the ViewCube, and click Home.
9. To display the hidden components on the canvas, in the Browser, click next to the Plate and Original Shape components.
Apply a force load to the interior face of the Pin Bearing component.
1. On the canvas, select the body highlighted in blue as shown in the following image.
2. To hide the pin on the canvas, in the Browser, click next to the Pin component.
3. To deselect the body, click anywhere on the canvas.
4. On the Define tab, click Design Conditions > Structural Loads .
  
  Warning: You can apply loads to preserve geometries only.
5. In the Structural Loads dialog, verify that Force load is selected.
6. On the canvas, select the face highlighted in blue as shown in the following image.
7. To change the current view, click the Front of the ViewCube.
8. In the Structural Loads dialog, for Direction Type click the Vectors (x, y, z) icon .
9. In the Fx input field, enter 1250.
  
  The arrow displays on the selected face as shown in the following image.
10. Click OK.
11. To verify that the force load is applied properly, expand Load Case1 > Loads.
  
  Tip: To modify the applied load, do one of the following:
  - Mouse over it in the browser, and then click .
  - On the canvas, double-click the arrow icon.
Clone the load case 2 times.
1. In the Browser, right-click Load Case 1 and select Clone Load Case from the context menu.
  
  Load Case 2 appears in the Browser.
2. Repeat the previous step to create an additional load case.
  
  Load Case 3 appears in the Browser.
Modify the Force2 load for Load Case 2.
1. Double-click Load Case 2 to activate this load case.
  
  Load Case 2 is highlighted in blue in the Browser.
2. In the Browser, expand Load Case 2 > Loads.
3. Mouse over Force 2, and then click .
4. In the Fx input field, enter 662, and in the Fz input field, enter -662.
  
  The arrow displays on the selected face as shown in the following image.
5. Click OK.
Modify the Force3 load for Load Case 3.
1. In the Browser, right-click Load Case 3, and select Activate Load Case from the context menu.
  
  Load Case 3 is highlighted in blue in the Browser.
2. In the Browser, expand Load Case 3 > Loads.
3. Select Force 3, and then click .
4. In the Fx input field, enter 0, and in the Fz input field, enter -2500.
  
  The arrow displays on the selected face as in the following image.
5. Click OK.
6. To display the pin on the canvas, in the Browser, click next to the Pin component.
7. To return to the Home view, move the cursor over the ViewCube, and click Home.
