Abstract

Conventional steel leaf spring is analyzed at maximum load using finite element analysis (FEA), ANSYS v16 software. The finite element results showed stresses and deflection, and then by using the results of the steel leaf spring, a composite one made from carbon fiber with epoxy resin CFRP is designed using FEA. The objective was to obtain safe design of CFRP composite leaf spring with less weight and the same stiffness of that the steel one. In the study, safe design means that CFRP composite leaf spring has high safety factor in stresses and high natural frequencies. Static, modal and harmonic analysis for both steel and composite leaf springs has been carried out using FEA. The results showed that the CFRP composite leaf spring withstands against failure and resonance where it has much higher factor of safety in stresses and higher natural frequencies with weight reduction 79% over conventional steel leaf spring.
