Abstract: This study focuses on the Formula Student China (FSC) braking system rule requirements, with lightweight as the core design objective. By analyzing the parameters of the racing car, the relevant parameters are designed to meet the requirements of the race. Then, modeling software is utilized to design the braking system parts, and simulation analysis is carried out with the assistance of ANSYS software, aiming at verifying the adaptability of the designed parts to the requirements of the racing car, and guaranteeing its safety and reliability. To validate the reliability of the optimized parts, the real car debugging and verification work is carried out. The results indicates that the designed braking system is practical and fulfilled the requirements of braking stability, and could realize the simultaneous locking of four tires as well, which aligns with the FSC braking system design rules. Moreover, an overall weight reduction of 35% (from 7.45 kg to 4.87 kg) is recorded for the braking system through replacing the sliding rail with new lugs, innovative hollow design of the brake discs and the application of a new throttle limit device. Additionally, the strength of the new design has been verified by both simulation and real-vehicle experiments, and the novel design satisfied both standards and design expectation. Overall, this work is of great significance to enhance the performance of the racing car and ensure compliance with the race regulations, which also provides effective technical reference and practical work for the design of the braking system of the Formula Student China.
