Thanks Greg & israelKK
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...
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 )
