Finite element analysis of composite leaf spring

This paper analyses the mechanics characteristic of a composite leaf spring made from glass fiber reinforced plastics using the ANSYS software. Considering interleaf contact, the stress distribution and deformation are obtained. Taking the single spring as an example, comparison between the performance of the GFRP and the steel spring is presented. The comparison results show that the composite spring has lower stresses and much lower weight. Then the automotive dead weight is reduced observably.
