The present project focuses on the fabrication and testing of a leaf spring, a critical component in vehicle suspension systems. Leaf springs are widely used in automobiles to support loads, absorb shocks, and ensure ride comfort. The main objectives of project is to fabricate a leaf spring, using suitable materials, and evaluate its mechanical performance under different loading conditions. The fabrication process involves selecting appropriate raw materials, shaping the spring, and assembling it according to design specifications. Subsequently, the leaf spring is subjected load testing and deflection analysis to determine its strength, stiffness and durability. The experimental results are compared with theoretical calculations. This study provides valuable insights into material behavior, structural performance, contributing to safer and more efficient suspension systems.
