Multi-physical model for tyre–road contact – the effect of surface texture

Abstract

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

Finite Element Analysis of Tyre Contact Interaction Considering Simplified Pavement with Different Aggregate Sizes

“…Yu et al [18] selected seven parameters to characterise pavement texture features and analysed the impact of those features on pavement skid resistance. Sharma et al [19] developed a multi-physics tyre-pavement contact model based on the temperature and pavement texture, focusing on the impact of pavement macrotexture on tyre-pavement interaction. Finite element simulation technology can be applied to further analyse tyrepavement contact interactions; however, in analysing the factors affecting tyre-pavement contact interactions, previous studies considered the tyre factors but ignored the effect of the pavement macrotexture and considered the effect of the aggregate surface properties but paid little attention to the effect of the aggregate grain size after the aggregate texture was abraded.…”
