| 摘 要： | 模态参数反映了物理系统的本质特征。利用模态参数对轮胎的垂直特性进行了建模，建立了接地印迹内摩擦力分布的计算模型，其结果与实验结果相符合。还发现轮胎的垂直特性与地面和轮胎之间的附着系数有关，这是以往建模方法所不能做到的。分别对轮胎与平面、轮胎与转鼓曲面相接触的垂直特性进行了建模。两者之间的关系与以往基于试验的经验公式所得结果是一致的。显示出利用模态参数对轮胎不同工况特性建模的优越性。

| Abstract: | Modal parameters are basic parameters of tire system. They are used to establish tire model on vertical properties in this paper, especially on friction force distribution in contact patch. The result of calculation is proved by the experiment. The relationship between tire vertical properties and friction coefficient of road has been found in the calculation, which can not be calculated with other modeling methods. The calculated contact properties of tire on drum surface are also presented to show the advantages of this modeling method. The results of calculation accord with the empirical equation given by reference well. |
