In the attached assemblies, I'm trying to understand what to use for the damping coefficient. It plays a large role in the results, but I'm not sure if it's a calculated value, and if it is, I'm not sure how to calculate it. Any help with damping coefficents in general would be appreciated.
I find it to cumbersome to unpack the zip.
Maybe you can just insert a few pictures.
I assume you want to use a damping coefficient in dynamic response analysis.
For a steel plate hanging on a wire (actualy not supported) the damping is very low. If you were to hit it, it will ring "forever". In that case the damping is about 0.001%.
For a normal mechanical assembly using screws and bolts and/ or spotwelds typical damping values vary between 3 and 5%.
If that's not accurate enough for you, you'll have to perform measurements.
Hope this helps.
