Stress Analysis of Leaf Spring Suspension System with the Combination of Helical Springs

Abstract

This research article deals with a modified version of leaf spring suspension system introduced for the optimization of existing leaf spring suspension system design, by the combination of two helical springs with the master leaf. To furnish this end, a semi-elliptical type mono leaf spring of light weighted mini truck is considered for design and modeling work. On both the sides of this mono leaf, a helical spring is designed and modeled at equal distances from the center of leaf. All the modeling and analysis work is performed in CATIAV5R20. Stress analysis results at various loading conditions are obtained by both theoretical and FEA methods, separately for typical mono leaf spring model and proposed model with helical springs. Results show an average 8.3% stress reduction for any of the loading conditions, by the utilization of helical springs with the combination of master leaf. The proposed work have some certain benefits which could definitely transform the existing leaf spring design into a more optimized, stable and flexible one for the overall better performance and comfort to passengers.
