I am doing a dynamic analysis of a grinding equipment using Ansys Workbench - Transient analysis. The equipment consist of Cylindrical double roller bearing and Taper double roller bearing. Bearing is not designed in detail, instead we have provided the Revolute joints. What is the role of Torsional stiffness and damping in the bearing joint and how to calculate the values.

I did some research on this and what i've found this:
Add commandline inside of ANSYS mechanical.
(TB) use this command with extras to add rotational stiffness to the specific element.
JNS is for stiffness and JND for damping.
Hope it helped and i understood your question.

Thanks for your reply. I would like to know, how to calculate the torsional stiffness and damping in bearing.
I want either the literature study or the Ansys procedure to calculate the stiffness and damping of Taper and Cylindrical double roller bearings.
Thanks in advance.
