Abstract
The growing need for improved performance and economy in large vehicles has spurred developments in suspension systems. This report outlines the creation and examination of a composite leaf spring intended to substitute conventional metallic springs in suspension systems for large vehicles. Composite materials renowned for their exceptional strength-to-weight ratio and resistance to corrosion have significant advantages compared to traditional steel leaf springs. The research starts by designing a composite leaf spring with a specific emphasis on optimising material qualities and shape to get the specified performance parameters. The composite leaf spring is assessed for its structural integrity fatigue resistance and general functioning under different load circumstances using Finite Element Analysis (FEA) and experimental testing. The results suggest that the composite leaf spring outperforms its steel equivalents in terms of decreased weight and improved durability. Furthermore the composite construction showcases enhanced ride comfort and handling attributes. The research finishes by examining the practical consequences of implementing composite leaf springs in heavy vehicle applications emphasising the advantages as well as the possible difficulties.
