Abstract

Traffic noise has become an important issue for mental health. Tyre/road noise, caused by the interaction between tyre and road surface, is a significant contributor to road traffic noise. Current tyre regulation aims at noise abatement. In order to predict tyre/road noise accurately, advanced numerical models are needed. Most current tyre/road noise models, however, are not accurate enough to predict tyre/road noise based on physical models. Hence, a new method has to be proposed. A numerical tyre/road noise model has been built based on physics. It consists of a structural vibration model using finite elements and a sound radiation model using boundary elements; both models are coupled by the tyre vibrations. The numerical model, which takes into account structural mechanisms only, has been validated for a slick tyre rolling on various road surfaces at different speeds. For the experimental validation, a device has been developed by which tyre/road noise can be measured on a moving car. The simulation results are in accordance with the measurement results in a sense that they show the same trends. The numerical model can be used to develop more silent tyres and roads. Due to its modular built-up the model is applicable for patterned tyres as well.
