Frame subjected to centrifugal force

Hello,
I would need to simulate a small aluminum alloy frame, see attached picture.

 

Has anyone ever done this kind of simulation before?


I'm still on Creo 3.0.
Sincerely.
Denis

Re: Frame subjected to centrifugal force

Hi.

This is a common simulation.  There are many ways to constrain at the bearings, depending on your specific situation.  Constraining all 3 translations at both bearings is the most simple example. (image)  Please try several ways on your own and think about whether the results make sense. 

 

There are many examples on google, including Creo simulate live, showing how simple this can be to study.  This Autodesk example has some good documentation that can help you understand this type of analysis. 

The centrifugal load is a body load and is like a gravitational field centered on the axis of rotation, generating force outward radially, or tangentially if desired, due to the mass/inertia.  A similar load would be a gravity load, which is a body load in one translational direction.  These loads are similar.  Gravity is translational, and centrifugal is rotational.   There is also inertia relief, which applies a body load to automatically balance a component that is not fully constrained statically.
