AN APPROACH TO DESIGN A COMPOSITE MONO LEAF SPRING USING FEA

Abstract


The aim of this paper is to design a mono leaf spring with a minimum weight and the same stiffness as a conventional mono leaf spring for a passenger vehicle. Finite element analysis using ANSYS 14 of the steel leaf spring and unidirectional E-glass epoxy composite (UEC) with fiber volume fractions (Vf) 0.5, 0.6 and 0.7 has been carried out. For each Vf the thickness of the spring was estimated to obtain the same stiffness as the conventional steel mono leaf spring. The analysis showed that safe composite mono leaf springs with same stiffness, same strain energy stored and with a beneficial reduction in weight can be designed by changing the thickness of the spring depending on the Vf.
