摘要
本文在稳态指数统一模型和一阶线性微分方程的基础上,研究了大侧偏角下动态过程中侧偏松弛长度的特性。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。深入了解侧偏松弛长度的特性对研究轮胎动态特性和建立轮胎动态模型具有重要的作用。
On the basis of steady state tire model and first-order differential equation, the property of relaxation length in transient process is studied. 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. Thoroughly understanding the property of relaxation length is very important in studying tire transient property and setting up tire transient model.
