Exterior vehicle noise has a very big impact when it comes to environmental noise pollution. Due to the decrease of the other noise sources of a passenger car, like power-train and air turbulence noise in the last decade, the tyre/road noise has become a more important part in the overall noise generation of a vehicle nowadays. It is considered as the main noise source in nearly all driving conditions, especially with increasing vehicle speed. The easiest idea to tackle this pollution is to introduce rules like speed-limits to control the noise at a certain area or time. More interesting, however, is to approach the problem of unwanted noise directly at the source. This Thesis, carried out at Loughborough University, aims to give a better understanding about the basic noise generation mechanisms at the tyre/road interface. Especially, the air related mechanisms of closed cavities are analysed. With the usage of a solid rubber tyre, unique measurements have been carried out and the results are compared to the theories already existing in the literature. These measurements reveal some of the strengths and weaknesses of the current understanding of air related noise generation.

The complex nature of tire/road noise generation process makes it difficult to isolate and study individual mechanisms. In this thesis, a new computational fluid dynamics (CFD) tire noise prediction model is used to predict the air-borne tire noise. The different factors needed to be considered in the development of the CFD model, such as vehicle speed, deformation and load, have been discussed in detail through various analysis stages. Experimentally, the noise data is collected and studied for a tire with hand-cut slots. Air-borne noise is isolated by filling the slots with foam and different approaches are used to investigate the experimental data and reach a conclusion regarding the different air-borne noise frequencies that exist in the data. A direct comparison between the experimental and computational results is made, in terms of temporal and spectral characteristics. The comparison shows that the computational model is capable of predicting the frequencies responsible for noise generation mechanisms such as air-pumping, pipe resonance as well as Helmholtz resonance. Further analysis of the numerical results also aim to provide some explanation on the origin of the air-borne noise in the tire studied. While providing a deeper understanding of the causes of air-borne noise in tires, this thesis also aims to demonstrate that CFD can be used to predict tire noise effectively, through the proposed model.

Ihrer Arbeit in der Originalsprache: This work aims at identifying relevant road surface characteristics to mitigate tire-road noise of free-rolling tires using a systematic approach. As using open porous roads is already known as an efficient measure to reduce tire rolling noise, this study will focus on compact road surfaces which have a low acoustic absorption. Measurements on standardized ISO 10844 test tracks and on public roads are used to study the norm's representativity and its completeness.
