ANSYS workbench interface CREO
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

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:
-
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"
-
Step 3: Open Ansys workbench
Click on the ANSYS icon named "Workbench" (in the upper left corner)
-
Step 4: ANSYS interface
ANSYS will open
-
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.
-
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.
-
Step 7: Static Structural
From the Toolbox, select and drag the "Static Structural" to the Project Schmetic "Geometry" with the Creo icon.
-
Step 8: Open model
`In Static Structural double click “model”
-
Step 9: Static Structual- Mechanical
A new window will open “Static Structural -Mechanical”
-
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>
-
Step 11: Starting FEA
Select “Static Structural”> define support
Select “Static Structural”> loads
-
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
-
Step 13: Apply forces
Apply forces (similar steps as support).
Select load > Selection geometry> define by “Components” > user definition
-
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)”
-
Step 15: Check Parameters
check parameters for Maximum under results for both “Equivalen Elastic Strain” and “Total Deformation”
-
Step 16: Begin solving FEA
click “solve”. Mesh Status will pop-up.
-
Step 17: Animation of Result
toggle between “total deformation” and “Equivalent Elastic Strain” and animation for visuals.
-
Step 18: Check out Result bar
use Result window bar to locate maximum and other features.
-
Step 19: Parameter Set
Back to ANSYS WorkBench select “Parameter Set”
-
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.
