Wave spring - deformation / constraints virtual wall

I´d like to calculate the reaction force due to a given deflection of a wave spring.

The spring is held between to planar faces and stays there while compression.
There is clearance between the bore diameter and the outer diameter of the spring.

The Geometry:


How i model it: (i´d like to know if there is a better way)


(3 bodies - upper and lower "wall" rigid)


My thoughts on the constraints:
On the bottom of the spring i´ll use a virtual wall constraint - so the spring can lift/tilt of the surface freely but can not penetrate it.
But how do i model the top deflection without using a 2nd body (like shown in the image above)?

  • the contact area changes
  • tilt/lift possible


Thanks in advance,
