This paper discusses an activity whose scope is to develop of a predictive full-vehicle finite element model for side crash simulation (FMVSS314). The main aim is to underline the meaningful problems and to find out possible solutions in a crash analysis made by Pininfarina Ricerca e Sviluppo CAE group (research department of Pininfarina S.p.A.). It is argued that computer simulations can help automotive manufacturers to reduce budgets testing campaigns and to increase safety requirements. It is difficult to affirm that increasing computing performances pull on the FEM software to improve reality representations or vice versa, but it is clearly evident that the trend is to increase the number of elements in FEM model. The accuracy of vehicle crash behaviour can be related to the density of elements in more complex stress-strain regions and the capabilities to capture exactly the geometry and inertial properties. Weld models besides play an important role in realistically representing the stiffness of the welded assemblies. This paper describes the fixing activities of a FEM full vehicle model and the obtained results.
