Parametric Analysis of Parabolic Leaf Spring for En45 /GFRP/Epoxy

Abstract

Comparative analysis of parabolic leaf spring for different materials has been conducted in the present work using FEA software. Three materials considered for spring areEN45, epoxy and GFRP (Glass fibre reinforced polymer). Springs absorb vibrations, shocks and loads in the form of potential energy andthis quality of springs makes the suspension systemeasy.A comparative study has been conducted in this paper to investigate the design and analysis of parabolic spring by analysing stress and deformation. Weight analysis has also been conducted for different cases considered in the work. Parabolic leaf spring made of epoxy-material shows less deformation for same loading condition which indicates large load bearing capability of epoxy material compared to the GFRP and EN45. Same amount of stress has been observed in the GFRP, epoxy and EN45 under loading condition.One fourth weight reduction in parabolic leaf spring has been found when it is made of epoxy and GFRP compared to the EN45. It can be concluded that epoxy serves better in respect of weight and deformation. This study helps in better understanding of the leaf spring.
