Abstract:

In now a day the fuel efficiency and emission gas regulating of automobiles are two important issues. To full fill this problem the automobile industries are trying to make new vehicle which can provide high efficiency with low cost. The best way to increase the fuel efficiency is to reduce the weight of the automobile. The weight reduction can be achieved primarily by the introduction of better material, design, optimization and better manufacturing processes. The automobile industry has shown increased in the replacement of steel spring with E-glass/epoxy composite leaf spring due to high strength to weight ratio. Therefore, the aim of this paper is to present a low cost fabrication of complete mono composite leaf spring and mono composite leaf spring with bonded end joints. Also, General study on the analysis and design. A single leaf spring with variable thickness and width for constant cross sectional area of unidirectional glass fibre reinforced plastic with similar mechanical and geometrical properties to the multi leaf spring, is to be designed. The result is to show that unisprung width decreases hyperbolically and thickness increases linearly from the spring eyes towards the axle seat. The finite element result using ANSYS software showing stresses and deflections were to be verified with analytical. The design constraints were stresses and displacement.
