torque spring in compression and expansion

[p3ppi]

Good evening to all,
looking in the forum I don't find a discussion about what I'm looking for and reading the solidworks guide is very long. I looked at tutorials on youtube but I can't find my specific case.

I should reposition a wheel in a position that I would call neutral position every time it is turned alternately clockwise and counterclockwise. I need the spring to be twisted. the wheel would turn about 270° to right and 270° to left and the neutral position of the spring would be 0°.

I'm trying to do motion analysis to size this spring.

the point where the spring is completely discharged and therefore in balance I have to define it, can not be random. I tried to put two springs but the simulation doesn't work. In fact the finished particular will have a single spring.
from what I understand I can't do motion simulation with the spring in the animation, but that doesn't interest me, I just care to insert it as "force" in the motion analysis.

Although the speech is not smooth, I think it is understandable, and if so I will not try to explain myself better.

Thank you for your help,
p3ppi.

Good evening,
Perhaps I am not very clear, but I am aware that the spring does not stop at that point for the inertia of the flyer, but I need that if let go it stops on that position.
then regarding the realization I solved the problem of the neutral position with a regulation of the spring.
the fact that I need is the spring constant that must be as a result of the return time.
I am looking with solidworks to calculate this time.
