Structural Mechanics: Eigenvalue analysis of moving bodies with sliding friction

I want to do an eigenvalue analysis for a system of deformable bodies, which are in relative motion and have a contact with sliding friction. As an example, think of a rotor in a non-lubricated bearing or a vehicle disk brake rotor sliding through the brake pads.
Other FE-software allows to impose motions to individual bodies, which produce centrifugal and gyroscopic terms. After linearization, these motions produce contributions to the systems stiffness, gyroscopic terms and the linearized friction force enters the systems stiffness and damping.
Is there a way to impose motions on objects in COMSOL?
Or, giving an example: how to model a rotating brake disk sliding through the brake pads for eigenvalue analysis (i.e. not doing time integration)?
Thanks in advance for any hint or advice!
Best regards
