Vehicle Dynamics on an Electric Formula SAE Racecar

Abstract

Vehicle dynamics on a Formula SAE vehicle are inter-dependent with almost all mechanical systems on the car and require a thorough understanding of design tradeoffs in order to maximize the vehicle’s acceleration capabilities while maintaining consistent driver feedback. This thesis summarizes the developments and accumulated knowledge on MIT’s Formula SAE team with regards to suspension and vehicle dynamics of the 2018 – 2020 seasons in order to inform the design and vehicle development for future years. Vehicle kinematics, vehicle dynamics, and tire selection are covered, in addition to the impact of aerodynamics, steering, and control arms on suspension development. Areas for further research are described. Throughout the thesis, the importance of quantifying and documenting design decisions is highlighted.
