Abstract: Virtual simulation of vehicle dynamics is of great significance in vehicle design. Based on the traditional vehicle dynamics theory, combined with CarSim vehicle dynamics simulation software, this paper puts forward a strategy for selecting the final drive ratio of formula society of automotive engineers (FSAE) racing car. According to the calculation method of the dynamic events in the rules of the college students' formula competition, the target score evaluation index is formulated. According to the real vehicle experiment of yixing formula team of xi'an jiaotong university in the 2019, 2020 season, the advantages of the selection strategy of the final drive ratio of the transmission system are verified. The research results provide some guidance for the design of the final drive ratio of FSAE teams.
