A Review Paper on Design of Leaf Spring

This paper reviews some of the general study on the design, analysis and fabrication of composite leaf spring. Leaf springs are one of the oldest suspension components they are still frequently used, especially in commercial vehicles. The literature has indicated a growing interest in the replacement of steel spring with composite leaf spring. The suspension system in a vehicle significantly affects the behavior of vehicle, i.e. vibration characteristics including ride comfort, stability etc. Leaf springs are commonly used in the vehicle suspension system and are subjected to millions of varying stress cycles leading to fatigue failure. A lot of research has been done for improving the performance of leaf spring. Lot of materials are used for leaf spring .but it is found that fiberglass material has better strength characteristic and lighter in weight as compare to steel for leaf spring. In this paper the author is reviewed few papers on use of alternate materials and effect of material on leaf spring performance.
