Introduction to SD/Simulation: Modeling of a Cylindrical Support & Perform FEA

Analyze the stress distribution and the deformation pattern of a cylindrical support, asshown below:

Step 1: Create a 3D solid model for the cylindrical support.

File > New > Part > OK.

In the Featuremode, click the icon of Revolved Boss/Base> pick the FRONT datumplane as the sketch plane. The orientation of this sketch plane is automatically set.

Pick the icon of Centerline> Vertical> For construction> Infinite length. Sketch avertical centerline through the origin of the default coordinate system. Press the Esckey.

Click the icon of Corner Rectangle > sketch a rectangle with its left side along the

vertical axis, as shown.

Select the icon of Smart Dimension. Click the vertical centerline first and click thevertical line on the right side, move the cursor to a new location, which is on the left side of thevertical centerline, and left-click to place the dimension. Upon the placement, a box will appearthat shows the diameter value. Change the value to 100 mm. To define the second dimension,

just click the vertical line on the right side and move the cursor to a new location. Change thevalue to 80. Click the check mark. Afterwards, click the icon of Done and Return.

The software system goes back to the Revolvewindow of the Featuremode (if not, clickthe icon of Feature), and click the check mark or Done.

Step 2: Add a round at the corner along the top edge.Click the icon of Filletand pick the top edge. Specify 10as the radius value. Click the

check mark or the icon of Done and Return.

Step 3: Create a thin wall structure using the Shell tool.Pick the icon of Shelland specify 5 as the thickness value. Pick the bottom surface.

Click the icon of Saveand type cylindrical_supportas the file name > Save.

Step 4: FEA analysis.

Click the SIMULATIONtab, which is listed together with the Feature tab. Expand theStudytab and click New Study.

Type shell_1as the Study name. Select Staticas the Analysis type > click the checkmark.

Click the Apply Material tab > From library files> search for Alloy Steel > OK.

To define the constraint condition, click the Fixturestab > select Fixed Geometry. pickthe bottom surface of the cylindrical support > Click the check mark.

To define the load condition, click the External Load tab> Force. Pick the top surface,as shown > specify 1000 N as the magnitude. Click the check mark.

Step 5: Create meshTo create the mesh for this beam model, highlight Mesh listed in the model tree, and

right-click > Create Mesh> pick the icon of OKto accept the default setting and click the checkmark.

Step 6: Run the FEA program.Click the Runtab > Run.

Step 6: Post Processing.

After the static analysis is complete, the software system automatically creates severalnew folders in the simulation model tree. These folders are Stress, Displacement, Strain, etc.

Users may directly open those folders to view the stress or displacement distributions. Undercircumstances, those folders may not be displayed in the model tree, click the Resulttab > NewPlot. At this moment, let us first show a plot of displacement. Click the Resulttab > New Plot>Stress> select VON(vonMises) > click the check mark or Done.

To show the displacement distribution, click the Resulttab > New Plot> Displacement> select mm as the unit> click the check mark.
