Design of an active tilting three-wheeler: optimization of the dynamic performances via multibody simulations

Nowadays, multibody simulations are widely exploited to validate and analyze mechanical systems whose functioning requires high dynamic performances. A global optimization of those dynamic systems can be carried out, producing more satisfactory results than classical approaches. We focus in this work on the family of road vehicles, characterized by a rather large number of design parameters and we propose a design methodology which takes dynamic issues into account from the earliest stages. The system parameters are classified in order to be processed afterwards by the suitable numerical module of the global design algorithm, rather than by the optimizer itself. The application of the proposed method concerns the optimization of the suspensions of a new concept of urban motorized three-wheeler under development in our laboratory
