Simulate a fan on the end of shaft

[seealtaf]

I want ot simulate a fan at the end of shaft or rather on the Motor-shaft. I dont want to add extra model, rather just use a rotating boundary condition or something.. How do I show that a fan is rotating on the shaft. Everything else is fixed.

What is the effect of the fan on the rest of the structure as you've shown in the picture?  Basically, if you were to have the fan attached to the little boss feature and the fan were to start rotating, how does it affect rest of the structure?

whatever the answer may be, you can also just create a dummy shape of the fan that has very similar mass/inertia as the original fan and model the attachment method correctly.

Hi

 

Perhaps the rotating force object/load, can be of some help in a full harmonic response analysis.

 

All the best
