Abstract
The main objective of this work is analyzing a Formula SAE chassis based in vehicle dynamics and your performance. This analysis was made using some suspension parameters and the main chassis stiffness parameter, the torsional stiffness. It is analyzed two methods for determining of the torsional stiffness, where the first is the model developed by Deakin et al. and the second the model of Sampò. Both methods use the lateral load transfer for determining the torsional stiffness, but the model of Deakin et al. use two masses, the front and rear mass in your analysis; differently, Sampò separate the mass in sprung mass and unsprung mass, then your analysis have four masses, and the lateral load transfer is obtained using the mass height center of these four masses. This work intends to obtain for 2018 and 2019 years the chassis torsional stiffness’s used by the Fênix Racing Formula SAE Team and also analyzing which the two models behaves better. In addition to finding out until when it could be adopted the Deakin et al. simplified considerations for the chassis design and from when the Sampò model necessarily should be adopted.
