Tyre air cavity influence on tyre-road noise
2005 (English)Conference paper (Refereed)
Road traffic noise is nowadays a major environmental pollutant. In the near future traffic noise will increase even further, especially due to the expected increase of heavy traffic. Noise radiated from tyres of the vehicles is a dominating source. The acoustic field inside the tyre has previously been modelled. The first acoustic mode for a standard stationary passenger car tyre is at 225 Hz. The tyre becomes stiffer at these tyre air cavity resonances and radiates comparatively high tonal noise to the exterior at this frequency range. In order to reduce this tonal noise at low frequencies a set of new modified wheels are developed implementing some sound absorbing material inside the tyre. Preliminary sound intensity measurements have been carried out on a static tyre. The influence of the tyre air cavity resonances on the radiated noise is reduced adding sound absorbing material inside the tyre.
