Abstract

The leaf spring can be made from several leaves stacked on top of each other in several layers, often with progressively shorter leaves. Leaf springs can serve locating and to some extent damping as well as springing functions. There are mono leaf springs, or single-leaf springs, that consist of simply one plate of spring steel. These are usually thick in the middle and taper out toward the end, and they don't typically offer too much strength and suspension for towed vehicles. Drivers looking to tow heavier loads typically use multileaf springs, which consist of several leaf springs of varying length stacked on top of each other. Springs will fail from fatigue caused by the repeated flexing of the spring. We are also considering these cases also. (1) Modeling of Road Irregularity. (2) The life and safety of the vehicle on road. Presently used material for leaf spring is forged steel. In this project we are going to design leaf spring for the material composite material carbon. We are going to check the strength variations while changing reinforcement angle and layers. Structural Analysis is done on the leaf spring by using three different material carbon epoxy. Fatigue analysis is to find life and safety factor.
