FSEC Racing Car Handling Stability Analysis and Optimization

Abstract

In this paper, the whole vehicle virtual prototype of the E22 pure electric formula racing car of Wuhan University of Technology for the 2020 season is built with the help of vehicle dynamics simulation software VI-CarRealTime tool, using multi-body dynamics as the theoretical basis. The suspension system of the vehicle is optimized. The steady-state steering characteristics of the car were analyzed through the simulation results of the virtual working conditions, and the four-wheel positioning parameters were optimized and matched to the specific working conditions. The optimized and matched car makes the steering characteristics of the car more consistent with the handling habits of the team’s drivers, improves the handling stability of the car, saves the optimization cycle for the whole car design process of the university’s formula car, and provides a reference for the design and optimization of the FSEC car.
