Design and Analysis of a Steel and Composite Material Leaf Spring
IJMTST, 2019
Leaf spring is a simple form of suspension spring used to absorb vibrations induced during the motion of a vehicle. The automobile industry has shown increased interest in the replacement of steel leaf spring (55 Si 7) with composite leaf spring (E-glass/Epoxy) due to high strength to weight ratio, higher stiffness, high impact energy absorption and lesser stresses. This research is aimed to investigate the suitability of natural and synthetic fiber reinforced hybrid composite material in automobile leaf spring application. By using natural fibers efforts have been made to reduce the cost and weight of leaf spring. In this work an attempt is made to develop a natural and synthetic fiber enforced hybrid composite material. With optimum properties so that it can replace the existing synthetic fiber reinforced composite material n automobile leaf spring. Jute and E-glass woven roving mats are used as reinforcements and epoxy resin LY556 is used as the matrix material. The CAD models of Leaf spring are prepared in CATIA V5 and imported in static structural analysis work bench of Ansys 14.5 where ignite element analysis (FEA) is performed. The design constraints are stresses and deflections. This study gives a comparative analysis between steel leaf spring and Jute/E glass reinforced Epoxy leaf spring. The hybrid composite leaf spring is found to have lesser weight, lesser cost, lesser stresses and higher stiffness.

Transstellar Journals, 2019
A leaf spring made up of steel, used in the back suspension system of the smaller passenger vehicle like car, is analyzed using analyzing software (ANSYS). By using the finite element analysis response, the stress induced and deflections occurred are substantiated in the analysis software. Using the results and dimensions of the existing leaf spring made of steel, a composite leaf spring made up of glass fiber with epoxy resin is modeled and optimization is performed in the ANSYS analyzing software. The main contemplation is given to optimizing the geometry of the leaf spring. The main objective is to examine the load bearing capacity, stiffness and the weight reduction of composite leaf spring with the leaf spring made of steel. From the result, it is evident that the optimum leaf spring width decreases exaggeratedly and the thickness increases straightly from the spring eyes to the axle seat of the spring. Compared to the leaf spring made of steel, the optimized composite leaf spring has much lower stresses and the weight of the spring without eye and its unit is nearly 79% lower.

In today's competitive world of the automobile industry, it is found that the continuous emergence of environmental issues, hiking of price in all respect, it is necessary to find the solution and analyse the few parameters such as weight reduction, optimise the design in the automotive component. In this paper, the material comparison have been considered and applied to the geometric model of the leaf spring, which is a very important component of the automobile segment. The geometric model of leaf spring with steel and composite material is established using the three dimensional software and then imported into the higher end finite element software to analyze its strength such as stress, deflection, and stiffness. The weights of two sheet plates have been considered for both steel and composite material and compared the weight reduction. The result showed that the E glass fibre composite leaf spring of two sheet plate has an 80% weight reduction as compared to the traditional steel leaf spring. This comparison showed remarkable the strength effect and the reduction in cost effectiveness can be easily achieved in the production sector.
Finite element analysis of hybrid composite material based leaf spring at various load conditions
Materials Today: Proceedings, 2020
Lot of effort is made to reduce the fuel consumption by automobile vehicles and this can be achieved by reducing the mass of the automobile vehicles. Leaf spring widely used in all types of vehicles including electric vehicles is one such component which could be attempted. Three different materials namely conventional steel, glass epoxy composite and hybrid composite (combination of both steel and glass epoxy) are considered for the leaf spring. FEA analysis is performed using ANSYS finite element code. Von-Misses stresses, deformation, principal stresses and strain are the main parameters that are considered in this study for different loading conditions. The mass of hybrid composite material is 34% lesser compared to conventional steel. Maximum principal stresses of hybrid composite material are 60% lesser than steel. The mass of hybrid composite material is 34% lesser compared to conventional steel. Finally, the hybrid composite material can be used as a leaf spring material thereby reducing the overall weight of the automobile vehicles.
