Leaf Spring in SolidWorks

I'm trying to model a leaf spring in solidworks like this one http://img.bhs4.com/09/D/09DCE41973B1EC906AB88B1953E507A180B80158_large.jpg

I've successfully modeled the 6 leaf spring using a parbolic curves but i have to change the specifications of the spring like the span length (eye-to-eye center distance, as shown in fig) for analysis purpose.
This is the sketch of my model http://i.imgur.com/A7BK2bx.png
I added a relation between both the eyes to be "equal". But when i change the span length say from 1100mm to 1000mm the "parabolic curve angle/radius" changes.

The problem is that all the leaves (curves) should be geometrically same except "length of leave (curve)".

This makes it difficult for other 5 leaves to have same angle/radius with change in only "length".

I want to add a relation with the all six curve's angle/radius to be equal with change in only "length".

Can i use equations? If i can, then can plz someone guide me in proper direction?

Thanks.

Thanks for feedback!

I followed and successfully created a model as shown.

I wanted to try assembly so I also modeled each leaves as separate part and then used "mate" while creating assembly.

Just one more question.

Your procedure, is it equivalent to creating a assembly using leaves as different parts and then mating them together? I mean, if i use same dimensions for both method then the model will be the same right?

Thanks again!

hello
can any here please tell me how to use simulation to find deformation in leaf spring.
thanks
