Design and Numerical Analysis of Leaf Spring Using Composite Materials

摘要

This paper describes design and analysis of composite a leaf spring made of E-glass/epoxy reinforced polymer. The aim of this paper is to introduce a new design as well as to compare the stiffness, load capacity and weight reduction of composite material with that of steel leaf spring. A comparative study of steel and composite material with respect to weight and strength was carried out on ANSYS 16.2 under the same boundary conditions in order to obtain the maximum deflection and stress. It found that the maximum deflection and stress in steel are higher than E-glass/epoxy, which recorded lowest deflection and stress by 51.7% and 57.1%, respectively. E-Glass/epoxy composite material reduced the weight of leaf spring 67.7 % compared to steel leaf spring.
