ABSTRACT

The purpose of this paper is to develop a multi-physical tyre model, which can take into account the influence of temperature and macro-texture of the road surface. The aim is to contribute to a better understanding and modelling of the tyre–road pavement interaction. This tyre–road interaction model can be used for friction estimation as well as rolling resistance estimation. Indeed, tyre–road friction has an undeniable influence on the rolling tyre; an accurate measurement of the tyre–road interaction is necessary for a better tyre design and simulations. The developed approach comprises mechanical and thermal models and gives dynamic forces and tyre temperatures as outputs. Comparison of simulations with experimental results to validate the model is presented and discussed. Special focus is given to the study of the impact of the macro-texture of road surface; numerical and experimental results are discussed. The experiments were done at IFSTTAR test tracks.

轮胎与路面接触的多物理模型——表面纹理的影响

摘要

本文的目的是开发一种多物理轮胎模型,该模型可以考虑温度和路面宏观纹理的影响。目的是有助于更好地理解和建模轮胎与路面的相互作用。这种轮胎-道路相互作用模型可用于摩擦估计以及滚动阻力估计。事实上,轮胎与路面的摩擦对滚动轮胎有不可否认的影响。轮胎与道路相互作用的准确测量对于更好的轮胎设计和模拟是必要的。开发的方法包括机械和热模型,并给出动态力和轮胎温度作为输出。提出并讨论了模拟与实验结果的比较,以验证模型。重点研究路面宏观纹理的影响;数值和实验结果进行了讨论。实验是在 IFSTTA 测试轨道上进行的。
