How-To on Rigid-Body Calculator Add On

Hello,

 

currently I am interested in determining the rigid body properties of a softly supported engine. I understand that it should be doable to get the moments of inertia and the COG by FRF measurements. But as I don't have experience doing this I would like to know if there is an example or a manual on this add on? I've been doing modal analysis but haven't used that add-on. For comparison of my results I do have CAD based moments of inertia and COG data so I can check that I get plausible results.

So far I found papers like http://pub.dega-akustik.de/AIA_DAGA_2013/data/articles/000583.pdf which are great but don't get too much into the practical aspects of it.

 

Thank you for any help on this! Best regards!
