This paper describes the exact method, which the author derived, for designing a two-stage leaf spring. The spring consists of a multileaf first stage, and tapered-leaf second stage. Using this method, the following can be determined:
1.
Spring rates and stresses when all physical dimensions are known.
2.
Leaf thickness and stresses for given rates.
In the Appendix of this paper, a sample of a step-by-step calculation is given, which makes the whole problem easier to understand.
Parabolic Leaf Spring Optimization and Fatigue Strength Evaluation on the Base of Road Load Data, Endurance Rig Tests and Non Linear Finite Element Analysis
