A leaf spring is a simple form of spring, commonly used for the suspension in wheeledvehicles. Leaf Springs are long and narrow plates attached to the frame of a trailer that rest above or below the trailer's axle. There are monoleaf 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. The shorter the leaf spring, the closer to the bottom it will be, giving it the same semielliptical shape a single leaf spring gets from being thicker in the middle. Springs will fail from fatigue caused by the repeated flexing of the spring. The aim of the project is to design and model a leaf spring according to the loads applied. Presently used material for leaf spring are forged steel. In this project we are going to design leaf spring for the materials Mild Steel and composite material Glass Carbon by varying reinforcement angle. We are going to check the strength variations while changing reinforcement angle. For validating this design we are conducting FEA  Structural Analysis is done on the leaf spring by using two different materials Mild Steel and Glass Carbon. Modal and fatiuge Analysis is also done. Pro/Engineer software is used for modeling and ANSYS is used for analysis.
