摘　　要：为提高FSAE(Formula SAE)赛车的圈速,对赛车的操纵稳定性进行仿真优化。首先使用TDFT工具箱中对Hoosier 43101 R25B轮胎的试验数据进行PAC2002轮胎模型的参数辨识,然后在VI-CarRealTime中建立整车虚拟模型并验证其准确性,最后依据8字绕环和蛇形绕桩工况的仿真结果,优化了侧倾刚度分布、外倾角和前束角等参数。结果表明,优化后的赛车在侧向附着能力和瞬态响应品质方面都有所提升,改善了整车操纵稳定性,同时也为赛车的调教提供了仿真依据。In order to improve the lap speed of the FSAE(Formula SAE)car,the handling stability of the car is simulated and optimized.First use the test data of Hoosier 43101 R25B tires in the TDFT toolbox to identify the parameters of the PAC2002 tire model,then build a virtual model of the vehicle in VI-CarRealTime and verify its accuracy,and finally based on the 8-word winding ring and snake winding Simulation results of the working conditions optimize the parameters such as roll stiffness distribution,camber angle and toe angle.The results show that the optimized car has improved lateral attachment ability and transient response quality,improved the handling stability of the whole car,and also provided a simulation basis for the tuning of the car.
