为轮胎滚动模型提供基础。
通过建立轮胎动力模型，利用基于模式搜索的最小二乘法对轮胎的纵向刚度和滚动半径两个参数进行了动态估计。
An dynamical model was developed in this paper for dynamic estimation of the longitudinal stiffness and rolling radius of the tires.
假定在轮胎滚动过程中，不发生平动，只有定轴转动，将平动速度施加在路面模型上。
It is assumed that tire is no translation, just rotation and the translation speed is applied to road model.
