How to do simulation/animate for a spring?

How do you do simulation/animate of compression/extension for a spring.
I have a downloaded model from Content Central
(by Scott Reed Synectic Engineering, Inc.Compression Spring - Ground Ends -)

Thanks

 

make your spring associative to the parts it mates to and animate thier
movement it should update for the animation.

I did something similar with a spring clip asociated the clip with a part
that was only planes and an axis and rotated the empty part to cause the
spring clip to update.

If you don't need to watch it change length, make some configurations of the
spring that have different values for the pitch of the helix.

check out www.mikejwilson.com There is some great answers to your question
there

 

I'm by no means a pro and had to do the same recently. To get the job done,
I modeled half the spring, created an assembly of two halves and mating them
to leave just linear motion. I then inserted that assembly into my main
assembly as a flexible assembly and mated each end of the spring assembly to
different parts in my main assembly. I can not move given parts and watch
the spring compress and extend based on the space available for it. True
the spring middle interferes with itself when compressed, but I'm the only
one who knows!

I made a small example and will send it to you. I will send the files and
the AVI.

I make springs with the length driven by then length of a segment in a
3D sketch. You could take such a model and associate the sketch
endpoints to parts in assembly.

I have a torsion spring model at the following location:

It's length is driven by a line in a sketch. It could readily be
modified into an extension or compression spring.
