Abstract

The contact between tyre and road is non-linear and most accurately described in the time domain. Currently however, accurate finite element models are too large to be solved at the small time scales required to capture tyre/road noise. At the Structural Dynamics and Acoustics group of the University of Twente an alternative contact algorithm has been developed. The algorithm solves the dynamic equations and, while solving, satisfies exactly the contact condition (the condition that states that there is no penetration of the tyre into the road). As a result, there is no need for contact elements and no additional parameters are required to stabilize the solution process. The possibility to optimize and speed up the algorithm by means of multigrid is the major advantage of the new approach. In this paper the contact algorithm is explained for a finite element discretization.
