Leaf Spring in SolidWorks

By Intruder16 on 31 Aug 11:22 5 answers 6383 views 3 comments

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.

    Use side distance dimension

    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!
