Exercise - Loads and Load Cases

Select Structural Loads from the ribbon - Allows for assignment of Pressure, Force, Moment and Bearing Loads.

Assign Force Load:

1. Select Force Load from the Type menu.
2. Select the inner diameter face of the top thick cylinder (as seen below).
3. Assign value of 26.7N
4. Click OK

 

 

 

 

 

 

5. Select Force Load from the Type menu.
6. Select the inner diameter face of the bottom thick cylinder (as seen below).
7. Click the Flip Direction button to invert the force direction.
8. Assign value of 26.7N.
9. Click OK.

Load Cases
A set of constraints and loads that act on a model at one time. Load cases simulate model behavior under different loads and constraints. You need to define at least one load case for a model. You can define multiple load cases for the same geometry. Load Cases can be Copied and then modified based on the required changes or a New empty load case can be created where all constraints and loads are to be reassigned. Let's try adding load cases to have three (3) load cases for this study.

Clone Load Case:
1. Right Click Load Case 1 and select Clone Load Case.
2. Notice Load Case 1 is still highlighted indicating that it is the active load case.
3. Double-click on Load Case 2 to activate it.

Modify Force Load:
1. In the Browser - expand Load Case 2.
2. Expand Loads.
3. Double Click the first Force to edit the assignment.
4. In the dialog type 90 in to X Angle to rotate the force orientation.
5. Click OK.
6. Do the same for the second Force assignment.

Clone Load Case:
1. Right Click Load Case 2 and select Clone Load Case.
2. Notice Load Case 2 is still highlighted indicating that it is the active load case.
3. Double-click on Load Case 3 to activate it.

Modify Force Load: 
1. In the Browser - expand Load Case 3.
2. Expand Loads.
3. Double Click the first Force to edit the assignment.
4. In the dialog click Flip Direction to invert the force orientation.
5. Click OK.
6. Do the same for the second Force assignment.

In the end we have three (3) load cases representing the forces acting on the preserves with the arm rotated fully to the left, fully to the right and straight.
