【摘要】 在赛车运行过程中,轮胎载荷是影响整车性能和安全的关键因素。本文建立了基于悬架受力的轮胎载荷解算模型,设计了一套FSAE赛车的轮胎载荷动态监测与预警系统。系统通过数据采集、数据分析和数据交互三大核心模块的协同工作,基于建立的模型动态监测和预警轮胎载荷状态。赛车手借助系统的数据反馈能够更精准地操控赛车,在发挥赛车极限性能的同时,有效降低高速行驶过程中的安全风险。通过实车测试,系统在静止、转向、制动等多种复杂工况下均展现出良好性能,误差率和断点率均保持在较低水平。实验结果验证了本系统及模型在解算轮胎载荷时的准确性和可靠性,为赛车底盘调校和新赛车设计提供了有力的数据支撑,为赛车运动的技术进步提供了新的解决方案。更多还原

【Abstract】 In the process of racing,the tire load serves as a crucial factor that significantly impacts the overall performance and safety of the vehicle.This paper establishes a tire load calculation model based on suspension force,and designs a dynamic monitoring and warning system for the tire load in FSAE racing cars.Through the synergistic work of three core modules:data acquisition,data analysis,and data interaction,the system can dynamically monitor and warn tire load condition based on the established model.With the data feedback from the system,drivers can more accurately control the race car,maximizing its performance while effectively reducing safety risks during high-speed driving.Through real-vehicle testing,the system has demonstrated excellent performance under various complex conditions such as static,steering,and braking,with low error and breakpoint rates.The experimental results verify the accuracy and reliability of the system and model in calculating tire loads,providing strong data support for chassis tuning and new race car design,and offering a new solution for technological progress in motorsports.更多还原
