Parallel leaf springs

Parallel leaf springs

Parallel leaf springs


I'm designing a construction with 2 leaf springs in parallel.
I have found the formulas to calculate the lateral stiffness of the leaf springs on following website: https://www.janssenprecisionengineering.com/page/f...
However, in my case, both leaf springs are under an axial tensile force of 40 kN.
I was wondering if the axial tensile force influences the lateral stiffness of the leaf springs and how I can calculate it. Does someone has a good reference for this?

RE: Parallel leaf springs

Yes it does and no I haven't. So if the spring deflects sideways by dy then there is a bending moment of 40kN*dy at the centre, tending to reduce the deflection. So all you need is your BM diagram (depends on constraints) and then solve in the normal way.

RE: Parallel leaf springs

I'm thinking of those cars with equivalent parallel control arms made from two transverse leaf springs, one above the other. Solve your springs like that as well?
