摘　　要：车架是汽车各部件的重要载体,对汽车安全性和稳定性等起着非常重要的作用。针对南京工程学院天印泠风车队“泠02”方程式赛车展开研究,利用ANSYS对车架进行拓扑优化及参数分析,得到最佳桁架结构、管件厚度和各工况下的车架强度并进行验证。结果表明,对比原有模型,扭转刚度提高了14.9%,质量下降了12.9%,该结果为大学生方程式赛车(FSAE)的车架研究提供了理论依据和设计指导。The chassis is a vital carrier for various components of automobile,and plays a crucial role on the safety and stability of the vehicle.In the study,"Ling02"formula racing car of the Lingfeng Racing Team at Nanjing Institute of Technology is investigated.Topology optimization and parametric analysis of the chassis are conducted using ANSYS to determine the optimal truss structure,tube thickness,and chassis strength under different operating conditions,which are subsequently validated.The findings reveal that compared to the original model,the optimized chassis exhibits a 14.9%increase in torsional stiffness while its mass decreases by 12.9%.This research provides a theoretical basis and design guidance for the chassis of Formula Student racing cars.
