The interaction of rolling tyres with road surfaces is one of the major contributions to road traffic noise. The generation mechanisms of tyre/road noise are usually separated in structure borne and airborne noise. In both mechanisms the contact zone is important. In order to reduce tyre/road noise at the source, accurate (numerical) prediction models are needed. For accurate results, the tyre has to be modelled by a threedimensional finite element model, accounting for complex rubber material behaviour, tread profiles and a detailed tyre construction. A dynamic analysis of a tyre in contact can then be carried out in the time domain. The Structural Dynamics and Acoustics group of the University of Twente has developed an alternative contact solver. The solver, in which the contact condition is always satisfied, is successfully applied to an implicit and explicit three-dimensional finite element model. As a consequence there is no need for contact elements or contact parameters. The finite element model is valid for large translations and rotations, in which different material models and friction models can be added. This paper explains the solver for an implicit and explicit scheme and presents some examples. In one of the examples a deformable rubber ring is modelled, which is rolling on a rigid surface at a slip angle. The results are compared to the finite element package Abaqus. The examples show the robustness and potential of the algorithm.
