Abstract
AbstractLeaf spring is the most integral part of suspension system in a commercial heavy-duty vehicle, which is used to absorb the energy caused by unevenness of the road. One of the most commonly used materials for leaf spring is 55Si2Mn90 grade steel. However, by employing light-weight composite materials, fuel consumption of vehicles can be improved. In this research work, a new model of leaf spring is proposed with four leaves and its stress analysis is carried out using finite element method. The proposed composite leaf spring consists of conventional steel material (grade 55Si2Mn90) at the top and bottom, while the other two leaves at the middle are made of hemp fiber/epoxy composite material. From the finite element analysis, it is found that there is a weight reduction of 37% when composite material is used. The stresses produced by the full capacity loaded vehicle are less than the yield strength of the composite leaf. Moreover, the maximum permissible load is four times than the load carrying capacity of the vehicle. Such observation highlights the capability and applicability of the present proposed design of the composite leaf spring, for safely incorporating in the vehicle.KeywordsLeaf springFinite element analysisNatural fiberHemp fiber/epoxy composite
