摘要通过对接地区域的胎面离散化处理，建立胎面纵向振动模型，引入动态摩擦模型—分布式LuGre模型，实现对滚动轮胎接地区域动态附着特性描述。针对某轮胎滚动工况，在Matlab/Simulink中进行数值模拟，通过调整模型参数，获得车速、胎压等对轮胎附着影响，验证模型的正确性、合理性；分析胎面接地区域摩擦力及位移的分布规律，为滚动轮胎纵向振动研究提供理论依据。

Abstract：

In order to model the dynamic attachment characteristics of a rolling tire’s tread, a dynamic model of tread in the longitudinal direction is proposed. Considering the dynamic characteristics of the friction in the tread’s contract area, a dynamic friction model, the LuGre distributed model, is employed to describe the attachment of wheel tread in this model. Then a series of numerical simulations under various conditions are implemented using Matlab/Simulink. The model is verified and the influences of factors such as speed, tire pressure are discussed. Furthermore, the distribution pattern of friction and displacement in the tread’s contract area is analyzed, which provides a theory basis for the research of rolling tire’s longitudinal vibration.

Key words： attachment characteristic tread dynamic friction model LuGre friction model
