EngD Position in Research on tyre stick/slip noise phenomena in tyres

When the tyre rolls over an uneven road surface, it starts to vibrate. Excessive force transmission and its combination with tyre resonances can cause discomfort. There are many different mechanisms at play which generate tyre noise. One of them is stick-slip phenomena which is responsible for high-frequency transient noise generation. It is therefore paramount to understand how tyre parameters such as cavity, construction, compounds, reinforcements, and tread pattern are responsible for stick-slip and stick-snap noise generation. This assignment aims to develop numerical and test methods to further study the influences of these parameters.

Goals and prototype deliverable of the project are: Document fundamental understanding on how tyre-road interaction generates stick-slip and stick-snap noise. Develop simulation methods to predict stick-slip and stick-snap noise mechanisms. Develop measurement methods to predict stick-slip and stick-snap noise mechanisms. Design know-how DoE to demonstrate how to influence stick-slip and stick-snap noise mechanisms. Evaluate prototype tyre design concepts with reduced stick-slip and stick-snap noises.
