The finite element (FE) modeling and analysis of a multi-leaf spring has been carried out. It includes two full-length leaves in which one is with eyed ends and seven graduated length leaves. Different types of material have been chosen like steel, aluminum, carbon epoxy and glass epoxy. The model of the leaf spring has been generated in Pro/e5.0 and imported in ANSYS-12 for FE analysis, which are the most popular CAE tools. The FE analysis of the leaf spring has been performed by discretization of the model in infinite nodes and elements and refining them under defined boundary condition. Bending stress and deflection are the target results. A comparison of different material results has been done to conclude the low-weight optimum model.References
