Abstract:
In the present paper, a typical Formula SAE double-wishbone suspension is discussed. This study aims to point out a preliminary chassis setup to reduce testing time on track and improve the overall performance of a prototype in a Formula SAE Skid Pad event. The influence of kinematic parameters of the suspension are analyzed to quantify how they change the capability of the tire to generate lateral force due to camber effects. To enhance results, special attention is given to a Magic Formula tire model based on a constrained forces and moments tire test data. Camber and Ackermann steering geometry showed up as major tuning tools to attempt during test period.
