Modelling corrosion effect on stiffness of automotive suspension springs

This work presents a numerical investigation that correlates the stiffness changes of corroded suspension springs with the amount of spring wire's cross section loss, the degree of surface corrosion (DSC), and corrosion spatial distribution. The aim is to provide understanding of corrosion damage characteristics and subsequent effect on the load-deflection behaviour of a helical compression spring. A 3D non-linear finite element (FE) model was...
