Abstract
An accurate analytical approach is usually preferred in engineering design for the reason that it does not involve additional software and can be useful for different studied cases. In this work, an analytical approach to evaluate bending stress distribution and to generate fatigue life diagrams has been carried out for Single Asymmetric Parabolic Leaf Spring (SAPLS). This approach is based on an analytical model which considers the SAPLS as an initially curved beam. Bending stress distribution results obtained from straight beam, Finite element and proposed models are compared for a case study. It is observed that the proposed model is more precise than the straight beam model (SBM) compared to FEM of SAPLS. To predict the fatigue life of the parabolic leaf spring, the Morrow criterion was used. This criterion takes into account the effect of the average stress and the residual stresses introduced near the inner surface of the spring. The proposed model has been employed to implement the iso-line diagram of fatigue life regarding various design parameters.
