DESIGN AND ANALYSIS OF COMPOSITE LEAF SPRING FOR LIGHT WEIGHT VEHICLE

In today’s scenario, the main weightage of investigation is to reduce the weight of product while upholding its strength. To solve that problem, this work is carried out for the design and analysis of mono composite materials leaf spring and entire new design criteria of mounting. The automobile vehicles have number of parts which can be able to replace by composite material. The foremost component of the suspension system of vehicle is leaf spring. It has substantial amount of weight, and it would have ample strength because it needs to resist vibrations and jolts during its working. The design considerations for this study are stress and deflection. Materials used for comparison are conventional, composite E-Glass/Epoxy, and E-glass fiber. In the present work deflection and bending stresses induced in the two leaf springs are compared The solid modelling of leaf spring is done in CATIA V5 and analysed using ANSYS 14.5. From the static analysis results, Grpahite Epoxy is better over other materials. It is found that there is a maximum displacement of 5.12 mm for Graphite Epoxy. Also, the Vonmises stress in the Graphite epoxy is 434.43 MPa
