Mass Spring Damper system with excited base

I'm trying to simulate with COMSOL 3D the behavior of a mass-spring-damper system applied on a plate that it's excited and moves.
The goal is to see how the mass-spring-damper system affect the displacement of the plate.
I was thinking to implement the forces with boundary load BC.
The force equation is the following:
mx'' + bx' + kx = F + by' + ky
The problem is that I don't have access to the displacement x, the velocity x' and the acceleration x'' of the mass of the actuator.
Can anyone help me with it?
You can find attached my COMSOL model and a picture that describe the system.
Thank you,
Mattia
