Abstract [en]

Studying rubber wear is important because it can save money, minimize health and environmental issues related to the particles generated from tyre wear and reduce fuel consumption. The wear of rubber is considered to be the result of energy dissipation due to friction. There are many models that describe the dynamical behaviour of vehicles and tyre, but less e ort has been dedicated to consider the tyre wear in these models.

The purpose of the thesis was to create an easy to understand and trend-accurate tyre wear model for implementation in a complete car model. The tyre wear in the thesis is determined to be the amount of rubber volume loss due to sliding per unit length that the tyre travels. A literature study was performed with the objective of gaining knowledge of tyre models and the a ecting parameters of tyre wear. The most important parameters in determining tyre wear were identied as the forward velocity, side-slip angle, longitudinal slip, vertical load, and tyre ination pressure. The wear was chosen to be calculated with Archards wear law for these parameters both separately and combined in pairs in order to obtain a deeper understanding of the wear.

The results show that wear is increasing exponentially for the forward velocity. Tyre wear decreases linearly as tyre ination pressure (vertical bristle sti ness) increases. The vertical load, longitudinal slip and side-slip angle yielded exponentially increasing wear. The most inuential parameters a ecting the tyre wear were the longitudinal slip and side-slip angle, these yielded wear rates up to 107 higher compared with the reference case.

The developed tyre wear model is a good base for future work. More measurement data are needed in order to validate the model. For future work it is also recommended to implement camber angle and temperature dependency in order to study these two important parameters inuence on tyre wear.
