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.
