A Review of Fatigue Analysis for Leaf Spring Using Finite Element Methodology and Experimentation for Evaluating the Variation in Material and the Geometry Affecting the Performance Over Life

Parabolic leaf spring plays a vital role in the suspension system. Since the failure of leaf spring is attributable to its fatigue loading. Cycle loads of a constant or varying magnitude and direction act and on the suspension system of the automotive that is sustained and borne by the leaf spring while the vehicle runs along the road. Pot-holes and bumps add the shock loads. This work aims to focus its research over assumption of the constant amplitude loading of the leaf spring for a passenger car. Finite element modeling would be employed to evaluate the existing design while offering the best alternatives for design. Feasible design alternatives would be started using F.E. Methodology. The benchmark design would be validated in advance for offering credibility to the F.E. model. Further analysis would be done for recommend of the most suited design for leaf spring..
