Dynamic analysis of Carbon Epoxy and E-glass Epoxy Composite material

The present work is carried out on a multi leaf spring having nine leaves used by a commercial vehicle, each leaf length, deformation and bending stresses are theoretically designed. The finite element 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 type of material has chosen like steel, aluminum, carbon epoxy and glass epoxy. The model of the leaf spring has been generated in Pro/E 5.0 and imported in ANSYS-12 for finite element analysis, which are 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. Experimental Analysis viz load test and vibrational analysis test has been carried out to E-Glass Epoxy.
