slugDesign and Analysis of Multi Leaf Springs Using Composite Materials
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2014, Vol 2, Issue 4
Abstract
Weight reduction has been the main/primary focus of automobile manufactures. The automobile industries have shown interests in replacement of steel springs with composite leaf springs due to high strength to weight ratio. The objective of this paper is to compare the load carrying capacity, stiffness and weight savings of composite leaf spring with that of steel leaf spring. This work is carried out on multi leaf of commercial vehicle. Mathematical calculations are carried out for design the multi leaf spring. The materials of the leaf springs are SAE 9260 and Glass fiber reinforced epoxy to be taken for comparative study. A Finite element approach for analysis of a multi leaf springs using Ansys software is carried out. The leaf spring model is generated by using Pro/E and imported in Ansys. Harmonic analysis for vibration due to road irregularities and static analysis for gross vehicle mass load analysis are carried out for both materials, and comparative behaviors are observed such as stress and deflection of the multi leaf spring.
