FSAE赛车动力学仿真中轮胎模型应用

Summary on Dynamics Simulation Tire Models of FSAE Racing Car

FSAE赛车的研发周期较短,应用仿真手段对其操纵性能进行模拟及优化是FSAE赛车设计中的重要过程,其中轮胎力学特性的准确表达是保证仿真准确度的重要基础。总结了FSAE赛车动力学仿真研究过程中UA轮胎模型、Fiala轮胎模型及魔术公式轮胎模型的选择及应用方法,简述了其建模机理,并给出了若干可以指导工程应用的结论。

Due to the short developmental period of the FSAE racing car, the simulation optimization for the FSAE racing car is an important design process, which are based on the expression accuracy of mechanical characteristics of tires. This paper is a summary of applications of tire models tbr dynamic simulation of the FSAE racing car, including UA tire model, Fiala tire model and Magic Formula tire model. The modeling basis of these three tire models was introduced and some conclusions which could be the guidance on design are proposed.
