DESIGN, ANALYSIS AND COMPARISON BETWEEN COMPOSITE MATERIALS WITH CONVENTIONAL MATERIAL OF LEAF SPRING

Abstract

This paper reveals the investigation of composite leaf spring and themodeling of the leaf spring with the use of different composite materials. The automobile industries are more competitive with low mass density with higher strength. Here is the work that compares the different composite leaf spring in which the parameters are considered such as static analysis and dynamic analysis. The modelingg of the composite leaf spring is done in SOLIDWORKS and then the static analysis is performed in ANSYS Workbench. It is also done in SOLIDWORKS to compare both the results and the dynamic analysis is also performed in the SOLIDWORKS software. A comparison has been made between laminated composite leaf springs, the materials are carbon steel grade (SUP9), S2 Glass Fibre, and Carbon Fibre(T300) which are having the same design and same load-carrying capacity. From that 79.22% weight reduction in composite material has been achieved for the same number of leaves and also high natural frequencies compared with other composites. From the result, the composite material of carbon fibre (T300) is best for leaf spring manufacturing.
