本文在第二章中研究了轮胎力学性能，分析其侧偏特性和刚度问题，并且得到轮胎侧偏角一变形模型；
In chapter 2, the paper studies the tire's mechanics capability. Side-drifting characteristic is analyzed, and the model of side-drifting angle-displacement is got.
在不变载荷下以时变侧偏角为激励，对轮胎模型进行了计算。
It is analyzed under time-varying side slip angle and constant wheel load.
侧偏松弛长度是由轮胎的侧向弹性决定的。在人侧偏角下，侧偏松弛长度不再是一个常数，而是随着侧向有效滑移率的改变而改变，而且它们之间呈现非线性特性。
The relaxation length depends on tire lateral elasticity and is not a constant but varies with slip rate, displaying a non -linear feature under large slip Angle.
