| Abstract Scope |
Reducing energy consumption and improving vehicle comfort has pushed car manufacturers to develop components that combine high mechanical performance and optimum lightness. Concerning the specific case of suspensions parts manufacturing, the materials involved require high mechanical characteristics coupled to a good ability to plastic deformation. These specifications imply severe conditions during forming, leading to tribological surface transformations in the case of springs. The aim of this work is to master these transformations by FEM modeling and refined material investigations (SEM, residual stresses and hardness). The 3D FEM model is made with ABAQUS, considering kinematic hardening effect on the one hand, and on the other hand tribological data. The interfacial characteristics have been obtained by means of a specific testing bench, able to reproduce industrial contact conditions. The mechanical variables of the model are coupled with a specific damage model in order to correlate to the metallurgical surface transformations. |
