Design and Analysis of Leaf Spring in ANSYS Using Different Materials

This study presents the design and structural analysis of an automotive leaf spring using Spring Steel and Phosphor Bronze to optimize performance and determine the most suitable material. A leaf spring is a long, narrow, and flexible beam composed of layers of plates (called leaves) stacked together in a curved shape. It is commonly used in vehicle suspension systems and is designed to absorb shocks, support the vehicle weight, and provide stability during motion. In this study, a 3D model of a leaf spring was created using SolidWorks, and Structural analysis was performed on the leaf spring using ANSYS Workbench by varying the materials of the spring to Spring Steel and Phosphor Bronze. Structural analysis was performed to validate the strength of the springs for different materials. A comparison was made between the two materials to determine the best material for Leaf Spring. This study began with an analysis of vehicle suspension requirements, encompassing performance and durability requirements, as well as various technical parameters. The key components of the leaf spring modeled in SolidWorks and Structural analysis were conducted in ANSYS using Finite Element Analysis (FEA) to assess the total deformation, stress distribution, and performance under loading conditions.
