Design and Analysis of Leaf Spring for EV Utility Vehicle

The design and analysis of leaf springs are pivotal for enhancing the performance and durability of suspension systems in heavy-duty vehicles. Leaf springs, essential for shock absorption and load distribution, have traditionally been made from high-carbon steel, valued for its strength and fatigue resistance. However, the high weight of steel poses challenges in modern vehicle design, where reducing unsprung mass is critical for improving fuel efficiency and vehicle dynamics. This project investigates the optimization of leaf spring design by exploring alternative materials, such as fiberglass-reinforced plastics (FRP), which offer significant weight reductions without compromising performance.
