A finite element approach for the simulation of tire rolling noise

A physically motivated modeling process for the prediction of noise radiated from rolling tires is presented. The overall simulation procedure is based on a decomposition into the nonlinear stationary rolling case, the eigenvalue analysis in the deformed state, and the calculation of the noise radiation including a modal superposition approach with an excitation by deterministic functions. The simulations cover detailed finite element models of the tire/road system. This allows for various parameter studies with respect to noise reduction potentials. The new model is applied to representative numerical examples, and its accuracy as well as its efficiency are discussed.
