Abstract
This work deals with the multi-objective dynamic optimization of the suspension system used for the front wheels of a single-seater vehicle. A half-car model is developed, considering the front suspension system mounted, while the rear suspension is replaced with a fictive spherical joint that is placed at the rear axle level. The purpose of the dynamic optimization is to minimize the chassis oscillations (yaw, pitch and roll), the monitored value for each design objective being the root mean square (RMS) during the dynamic simulation. The locations of some important attachments from the suspension system are used as design variables for the dynamic optimization. The dynamic model is analyzed in the passing over bumps regime, the wheels being anchored on driving actuators, whose motion simulate the road profile. Specific modules of the MBS (Multi-Body Systems) software environment MSC.ADAMS are used in this study.
