We designed the attached shaft with solid185 Elements. We have the goal to identify critical speeds of this shaft with a campbell diagram. This identification already works. The problem is the displacment. It is not plausible, because its scaled in meters and has an amount of more then 1 meter. I attached the visualisation as well.
Apart from that i plan to implement material and bearing damping. This doesnot work properly. By now its uncommented. Can you please check my concept. What value I should implement for the damping constants? I caclulated for the damoing keoficient a value of 1e-2. But it lowers the critical speed to 0rpms.
I would like to ask you, if you can try to help me identify the problem in my script. Perhabs it is a problem of unit setting or visualisation of result.
