Finite element analysis of coil spring by using carbon fibre, carbon steel and epoxy resin materials

Abstract

Coil springs stay one of the oldest suspension mechanisms. They are habitually used even now, particularly in the field of two-wheeled vehicles. The design of coil springs is based on compressive energy components. Location, celerity in addition to placement of the spring provides the thrust in the fork attachment positions. One more portion that requests focus, is the automobile industry which has given improved curiosity in exchanging steel springs for composite materials due to its high strength-to-flexibility ratio. Hence, examination and study of material become correspondingly vital to check the behavior of composite coil springs. In this study, analysis was done on composite coil springs using carbon fiber, carbon steel, and epoxy resin material. 3D modeling is prepared with CATIA V5 and Finite Element Analysis is done on ANSYS. The results show that among epoxy resin, carbon steel, and carbon fiber, carbon steel provides more strength compared to epoxy resin and carbon fiber. In finite element analysis, epoxy resin material has shown maximum deformation and has maximum stress concentration. Further various composite materials along with analysis (compression, tensile, wear as well as tear) are concluded by referring to the results in use from the FEA. From the results, carbon steel is found to be a superior material for coil springs.
