Tutorial objective outcomes:
-develop skill in ANSYS workbench FEA
-determine MAX stress location
-define loads
-define constraints

Background: FEA analysis on BAJA frame design. The Baja frame is model in CREO and surface sweeps. The frame surface is assigned a thickness in ANSYS workbench.

Pre-requite- ANSYS product/CAD configuration installed.

This tutorial is based on https://www.youtube.com/watch?v=5FqyNxxGzCs

1. Step 1: ANSYS workbench interface

   Situation: At this point your CAD model is complete, ANSYS Workbench CAD configuration is installed. 

   

   
   

   Tutorial is based on this video:

   
   

2. Step 2: Named Selection

   if you would like to reference this surface during the FEA process, otherwise skip to step 3.

   step 2.1: open the "Name Selection" window

   step 2.2: click "create"

   step 2.3: click and highlight the reference surface

   step 2.4: In the Name input dialog window, enter a surface name EX. "NS_towbar"

   

3. Step 3: Open Ansys workbench

   Click on the ANSYS icon named "Workbench" (in the upper left corner)

   

   
   

4. Step 4: ANSYS interface

   ANSYS will open

   

   
   

   
   

   
   

5. Step 5: Check Named Selection in ANSYS

   If you used the name selection feature (in step 2), check the box in row 19 in ANSYS, otherwise skip to step 7.

   

   
   

   
   

   
   

   
   

6. Step 6: Bonus:

   If you have defined parameters, watch the video from 3:28 to 4:05

   (this will allow very easy and fast parametric calculation known as “What if study” refer to video 6:55 to 8:45.

   
   

7. Step 7: Static Structural

   From the Toolbox, select and drag the "Static Structural" to the Project Schmetic "Geometry" with the Creo icon.

   
   

   

   
   

   
   

8. Step 8: Open model

   `In Static Structural double click “model”

   

   
   

   
   

9. Step 9: Static Structual- Mechanical

   A new window will open “Static Structural -Mechanical”

   

   
   

   
   

10. Step 10: defining surface to solid

    my model contains surfaces, I will define each surface with a thickness (skip this if your model is already a solid model).

    In Outline>Project>Model>Geometry>*Model Name*> select all> (under Details) enter value for thickness>

    

    
    

    
    

11. Step 11: Starting FEA

    Select “Static Structural”> define support

    Select “Static Structural”> loads

    

    
    

    
    

12. Step 12: Defining support

    Support can be defined using “geometry selection” or “Named Selection” (this is where the early named selection comes into play)

    By name selection: in named selection,> selection previously define> then continue on and define next support or load

    

    By geometry selection: selection feature then apply

    

    
    

    
    

    
    

13. Step 13: Apply forces

    Apply forces (similar steps as support).

    
    

    Select load > Selection geometry> define by “Components” > user definition

    

    
    

    
    

14. Step 14: Calculate for Von Mises stress and max deformation

    Next determining which parameters to solve.

    Select “Solution”> “Deformation”> “total”

    Select “Stress”> “Equivalent (von mises)”

    

    

    
    

    
    

    
    

    
    

    
    

15. Step 15: Check Parameters

    check parameters for Maximum under results for both “Equivalen Elastic Strain” and “Total Deformation”

    

    
    

    
    

16. Step 16: Begin solving FEA

    click “solve”. Mesh Status will pop-up.

    

    

    
    

    
    

    
    

    
    

17. Step 17: Animation of Result

    toggle between “total deformation” and “Equivalent Elastic Strain” and animation for visuals.

    

    
    

    
    

    
    

    
    

    
    

18. Step 18: Check out Result bar

    use Result window bar to locate maximum and other features.

    

    
    

    
    

19. Step 19: Parameter Set

    Back to ANSYS WorkBench select “Parameter Set”

    

    
    

    
    

    
    

20. Step 20: Numerical value FEA

    From step 15, we activated the parameters for Maximum displacement and Stress in this window we can see the numeric values.
