Solid Edge Understanding SE Simulation Buckling Study results

When creating a Buckling Study, I do not manage to interpret the results.
I am using the Siemens example model "FE_Cane.par" to show my difficulty to analyze.

Follow the exercise.

The results indicate a one meter displacement out of a one meter cane.

How should I interpret this?

Additionally, modifying the material from Aluminium to Titanium only changes the frequency mode.

Solution

Here are some basics on Buckling Studies.

Buckling Analysis is used to determine the load at which a structure becomes unstable.

-what you normally look for is the Eigenvalue.

The Eigenvalue multiplied with the applied load is causing the deflection. The Eigenvalue is found in the Simulation Pathfinder.

Eigenvalue x applied load = buckling load.
 

-you do not want to have Eigenvalues below one. This means your applied Load causes buckling.

-the deflection for a specific Mode can give you an idea on how the part will bend, but the value really is of no interest. This is why the Display options for a Buckling study hides the Contour as default.


-to see the actual deformation you should create a Linear Static study.

-if you look in the Femap examples there is a good example of a Buckling Study,
