For a rolling tyre, forces arise within the tyre-road contact patch, leading to the excitation of tyre vibrations and in turn to noise radiation. This is the main cause of highway noise and consequently much effort has been made to understand and model the tyre vibrational character as well as the sound radiation. However, when it comes to the generation of contact forces in the tyre-road interface, there is still a demand for future research. Specifically, the understanding and modelling of the influence from tangential force excitation on the resulting tyre-road noise is a complicated topic which involves many parameters such as tread rubber characteristics, road surface character, rolling velocity, rolling resistance and normal load. In this paper, an experimental study of the tangential friction contact forces which arise for a single truck tyre tread block in rolling contact with a road surface is presented. Both the dynamic tangential dynamic stiffness as well as the sliding frictional behavior of the same tread block is experimentally investigated. Moreover, an example measurement with the novel compact internal drum (CID) test rig is presented. The test rig can be used to study the influence on the resulting contact forces from parameters such as rolling velocity, road surface topography and normal load.
