Tutorial: Linear buckling analysis

Use buckling analysis to determine the load value at which a cane starts to deform before breaking. The study parameters used in this tutorial are:

• Study type=Linear Buckling

• Load type=Force

• Constraint type=Fixed

• Mesh type=Tetrahedral

1. Open the file FE_cane.par.

   Simulation models are delivered in the \Program Files\UDS\QY CAD 2022\Training\Simulation folder.

   

2. Create a linear buckling study.

   1. Select Simulation tab→Study group→New Study.

      

   2. Choose the Linear Buckling study type and Tetrahedral mesh type.

      

   3. Click OK.

      Note:

      The new study is listed in the Simulation pane.

      

3. Define a force load.

   1. Select Simulation tab→Structural Loads group→Force.

      

   2. Select the curved face on the handle.

      

   3. Select the origin of the directional arrow.

      

      The force directional steering wheel is displayed.

   4. Drag its origin to the circular edge on the bottom of the cane handle.

      

   5. Select the bottom cardinal point on the steering wheel to reorient the primary axis such that it points down.

      See Reorient the steering wheel for help.

      

      

   6. In the Value box, type 667 N (150 pounds-force).

      Press Enter to accept.

      

      The force is placed.

      

4. Add a fixed constraint to the base.

   1. Choose Simulation tab→Constraints group→Fixed.

      

   2. Select the planar face on the bottom and accept it.

      

   You can see the finished constraint on the model.

   

5. Turn off loads and constraints in the Simulation pane.

   

6. Mesh the part and solve the study.

   1. Select the Mesh command.

   2. Change the Subjective mesh size to 8, and then click Mesh & Solve.

      After a few moments, the entire part is meshed.

      

   The Simulation Results environment is displayed automatically when processing is complete.

7. Review the results.

   1. Select the Home tab→Show group→Display Options command.

      

   2. Select the Contour, Deformation, and Color Bar check boxes.

      

   3. These results are for the Mode 1 Eigenvalue. You can see this in the Home tab→Data selection group.

      

      

   4. Within the menu, you can read the entire Eigenvalue.

      

8. View results for different modes.

   1. From the Home tab→Data Selection group→Result Mode list, select Mode 2.

      

   2. From the Result Type list, select Displacement.

      

      The results change.

      

   3. Repeat for the remaining two modes.

      

      

9. Animate the modes.

   1. In the Home tab→Data selection group, change the Result Mode back to Mode 1.

      

   2. Select Animate.

      

      The Animate command bar is displayed. The modal results begin animating the cane.

   3. Click Pause.

      

   4. In the Properties group on the Animate command bar, select the Animate Across Modes button .

   5. Click Play.

      

   6. When you are finished viewing the animation, click Close.

10. Save and close this file.
