摘　　要：荷兰学者Pacejka提出的魔术公式Magic Formula和我国郭孔辉教授提出的统一轮胎模型UniTire在汽车操纵动力学研究中得到了广泛的应用。通过对这两种模型建模机理的对比表明,UniTire轮胎模型比MagicFor-mula模型具有更强的理论基础;通过试验数据辨识模型参数对比两种模型的全局辨识精度以及预测精度的结果表明,UniTire轮胎模型的全局辨识精度略高于Magic Formula模型,而且明显具有更高的预测能力。The magic formula present by Dr.Paeejka,Netherlands,and the united tire model UniTire present by professor Guo Konghui are widely used in vehicle handling dynamics studies,By comparison of their modeling mechanism of the two tire models,it is shown that UniTire model has stronger theoretical basis than the Magic Formula model;by comparison of their global identification accuracy and their predication accuracy,it is shown that the global identification accuracy of the UniTire model is slightly higher than that of the Magic Formula and the UniTire model has obviously greater predication capability.
