The influence of the contact features on the tyre wear in steady-state conditions

This paper focuses on invetigating the relationship between the contact features of the tyres and the tyre wear in a quantitative sense as a function of the tyre structure and the manoeuvre parameters by utilizing a modified theoretical tyre wear model. The modified tyre wear model was developed by combining a modified ring model for the tyres and a modified brush model and was validated. The model parameters were also identified by physical experiments. Moreover, the contact features were characterized as the contact length, the asymmetry factor and the rolling resistance shift in order to investigate the influence of the contact features on the tyre wear. The amount of wear versus the three key variables of the contact features with variations in the tyre parameters was plotted and analysed. The results show that the maximum normal contact pressure does not play the most important role in the tyre wear. An increase in the damping coefficient can lead to an increase in the tyre wear, whereas increases in...
