Abstract: This paper introduces the design optimization and working principle of the braking system for formula student electric China (FSEC) racing cars. In order to maintain good braking energy efficiency under extreme conditions of emergency braking and continuous braking of racing cars, corresponding calculations are carried out on each component of the braking system, and though the ANSYS static simulation analysis to ensure the stability of the braking system assembly. At the same time, it also has good human-machine engineering design to ensure that the driver maintains a good driving state for a long time during high-intensity driving. Research has shown that the optimized brake base plate assembly equipped with a fast adjustable mechanism based on gas springs can ensure braking stability while also allowing for rapid and stepless adjustment of the brake base plate without disassembling the front of the vehicle. Finally, the system is assembled on the 10th vehicle of the Wanda electric fleet at Liaoning University of Technology to verify the feasibility of the design. This research result can provide reference for the design of subsequent racing car braking system, improve the stability of racing braking, make it lightweight, and enhance racing car performance.

摘要： 文章介绍了中国大学生电动方程式大赛（FSEC）赛车制动系统的设计优化及其工作原 理，为了赛车在紧急制动和连续制动的极限工况下仍保持良好的制动能效，对制动系统中各 个部件都进行了相应的计算，并通过 ANSYS 静力学仿真分析来确保制动系统总成的稳定性。 在此同时，也具备良好的人机工程设计，以保证车手在高强度驾驶中保持长时间良好的驾驶 状态。研究表明，优化后的搭载基于气弹簧的快速可调机构的制动底板总成，可在保证制动 稳定性的同时也可在不拆车头的情况下，对制动底板进行快速无级可调。最终，将该系统装 配在辽宁工业大学万得电车队 10 号车上以验证设计的可行性。该研究成果可为后续赛车制动 系统设计提供参考，提高赛车制动稳定性；使其更加轻量化，提高赛车性能。
