Abstract

Leaf springs are the main suspension elements in an automobile system. This paper represents comparison of conventional leaf spring with composite leaf spring. It describes the design, experimental testing and numerical analysis of a composite leaf spring prepared by Epoxy Resin and E-glass fibre of Unidirectional and Bidirectional laminates. A 3D modelling of the leaf spring is created in CATIA V5.Static and fatigue analysis has done in ANSYS 17.0 WORKBENCH for both conventional leaf spring and composite leaf spring. Static load testing of both composite and conventional leaf spring is performed. The leaf spring made of glass fibre reinforcement polymer show higher strength and life when compared to conventional leaf spring.
