Simulating/Animating spring motion

Hi,
I'm trying to animate the motion of a spring compressing. I have the
spring part set up to dynamically change with the overall height (the
height dimension is in a sketch). How do I relate the height
dimension to vary from say 200mm to 100mm in 2mm increments and show
the resulting spring compression.
Thanks
Shane

I posted the following a month ago - maybe it would help:

The links below will allow you to download the compression spring, and an
extension and torsion spring I had laying around. The models are for
education on modeling strategy only - I did not look up any springs for
real, nor did I take a ton of time to clean up the models the way I would if
I was doing them for a customer/delivering to a customer.

By the way, the compression spring is kind of cool because it shows a trick
for getting equations to evalaute betwen frames in an animation. I needed
the spring to be equation driven so anyone could use it to add coils, change
diameter, etc without doing a lot of reconstruction.

 

Looks like mikejwilson.com is down.
