Abstract
The leaf spring is widely used in automobiles as major part of suspension system. These springs are intended to bare jerks and vibrations during traveling on uneven roads. The suspension leaf spring is one of the potential items for weight reduction in automobiles. The reduction of weight will achieve Fuel efficiency. The emphasis of this paper is on the application of FEA concept to compare three materials for leaf spring and proposed the material having best strength to weight ratio among them. Three materials used for comparing are the conventional steel, composite E-Glass Epoxy and Carbon Epoxy. This present work is to estimate and compare the deflection, bending stress induced in the leaf spring by these materials. The leaf spring, which is used for analyzing, is a mono leaf spring of Light passenger vehicle. A model of such leaf spring has been designed from actual steel leaf spring and analyzed using ANSYS in this paper. Theoretical calculations and Testing is done for validation of results.
