Calculation method of progessive stage/rate leaf springs.
Calculation method of progessive stage/rate leaf springs.
(OP)
Hi
This is Abhijeet Mitra. I am a designer of suspension systems in India.
Can somebody help me find the calculation method to find out stage stiffness of progressive/rate leaf spring ( Considering the length and camber of leaves in the spring system )

My basis of design calculations is SAE J 788. But in actual samples it is always observed that stage 1 stiffness is greater than calculated. For example if required stiffness values are 6 and 13 kgf/mm, then observation is 8.8 and 13 kgf/mm. Snapshot for concerned spring system is attached.

I'd use matlab, but here's an examplf ro a single leaf I did in Smath

You will also be able to model the effect of the second stage more accurately, although that gets very tricky.
