Design and Numerical Analysis of Leaf Spring Using Composite Materials

Abstract

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.

Mechanical Characterization of AA 6061-T6 MIG Welded Aluminum Alloys Using a Robotic Arm

“…Automobile and aircraft manufacturers use aluminum alloys of high performance and efficiency capabilities to design and manufacture safe and stable vehicles and aircraft. In addition, they seek to reduce fuel consumption and carbon dioxide emissions by utilizing lightweight materials [31,32]. These aspects are of ongoing motivation of researchers to improve the characteristics of aluminum alloys [33][34][35][36].…”

Structure Design of GFRP Composite Leaf Spring: An Experimental and Finite Element Analysis

“…Therefore, the lightweight design of the leaf spring is of great concern in the automobile industry [1,[8][9][10]. The fiber-reinforced polymer (FRP) composite possesses outstanding properties such as high stiffness and strength, low specific mass, and corrosion resistance, in combination with a flexible design, which has emerged as the viable candidate for the weight reduction applications without losing performance in terms of load-carrying capacity or stiffness [11][12][13][14][15][16][17][18][19][20][21].…”
