Summary on Grant Application Form |

The aim of the proposed work is to provide a better understanding of the mechanisms governing tyre/road noise generation. A mathematically-based model will be developed to predict the exterior noise generated at the tyre-to-road interface under various conditions of traffic operation. A combination of analytical and numerical techniques will be used to obtain an acoustic wave propagation model, describing the influence of the overall tyre/road geometry on the generation and propagation of acoustic waves. Appropriate mechanical models will be developed for tyre vibration in and around the contact patch. The cooling of the acoustic and vibration models will lead to a noise prediction scheme capable of identifying the effects of speed and tyre/road surface characteristics. This model will be validated against experimental data from both rolling road rigs and real road surface conditions. The improved understanding of the noise generation process gained in developing and evaluating the model will guide the future development of tyre and road combinations. Reductions in noise levels will only come through integration of the design of road texture and tyre treads patterns. This will become possible once the validated noise model is available.
