Design and analysis on composite multileaf spring in heavy commercial vehicle

Author(s): S Noor Mohammed, K. Durga Sushmitha
Abstract: A leaf spring is a simple form of spring, commonly used for the suspension in wheeled vehicles. LeafrnSprings are long and narrow plates attached to the frame of a trailer that rest above or below the trailer'srnaxle. There are monoleaf springs, or single-leaf springs, that consist of simply one plate of spring steel.rnThese are usually thick in the middle and taper out toward the end, and they don't typically offer toornmuch strength and suspension for towed vehicles. Drivers looking to tow heavier loads typically usernmultileaf springs, which consist of several leaf springs of varying length stacked on top of each other.rnThe shorter the leaf spring, the closer to the bottom it will be, giving it the same semielliptical shape arnsingle leaf spring gets from being thicker in the middle.rnThe objective of this paper is to compare the load carrying capacity, stiffness and weight savings ofrncomposite leaf spring with that of steel leaf spring. The design constraints are stresses and deflections.rnThe dimensions of an existing conventional steel leaf spring of a Heavy commercial vehicle are takenrnSame dimensions of conventional leaf spring are used to fabricate a composite multi leaf spring usingrnE-GLASS/EPOXY, C- GLASS/EPOXY, S- GLASS/EPOXY unidirectional laminates. Pro/Engineerrnsoftware is used for modeling and COSMOS is used for analysis. Static & Dynamic analysis of Leafrnspring is performed using COSMOS.
