Abstract
The rolling noise of the tires is the most dominant source of traffic noise at speeds above 50 km/h. A lot of experimental and statistical work has been done so far to get more information about the dependencies of rolling noise from typical parameters, such as the texture of the road surface, the tire width, etc. Those methods are expensive and it will be a hard task to derive statistical models for the predictive optimization of the wheel-road-system in its mechanical-acoustical interaction. In this paper a simulation technique for the prediction of rolling noise of tires based on detailed finite element models is presented. In contrast to the former methods, by these simulation tools it will be possible to study - in an efficient way - the influence of details of the tire construction as well as of the road textures. The first part of the presentation deals with modeling of the dynamics of rolling tires by finite elements. Both, the influence of gyroscopic effects and the treatment of nonlinear and history dependent material behavior will be discussed. A modal superposition technique will be applied to compute the vibration behavior of slick tires excited by the surface roughness. A second part of the presentation is dedicated to the acoustic analysis using finite/infinite and boundary element methods, where the results from the structural analysis are taken as boundary conditions to calculate the sound radiation of the tire.
