Is it a finite value of force (decreasing on each impact), EACH for a time interval T, or is it a series of decreasing impulses (Dirac delta functions), or ???

Then of course you need to determine the parameters defining your system. It had better be a second-order diff. eq. with constant coefficients. In other words, the equivalent of a spring, dashpot and mass.

Any other type of eq. & you have to use simulation software.

You're right, the damper does not solve your problem. You need to define the impacts by the forcing function in the diff. eq.

Once you have that you can solve the problem classically, or (as I would) using the Laplace transform. This is a transient problem, assuming the next set of impacts occurs much later.

PS - if the motion (vibrations) die down before the next impact arrives you have a much easier problem. But I imagine that's not the case or you wouldn't be asking in the first place, right?
