Boundary element analysis of rolling tire noise

The vibration and radiated noise characteristics of rolling tire was analyzed by virtual prediction method. The acceleration response spectrum of rolling tire was acquired through the method of analyzing the dynamic response under the road impact excitations by the modal superposition approach. The acceleration date of rolling tire surface were imported to the acoustics analytic software as the input load of the boundary element model, and the noise radiated from rolling tire by vibration were calculated. The disrupted and characters of the noise in different the tread pattern and road surface was discussed.
