Abstract
An overview on applications of advanced boundary element techniques in
automotive noise simulation is given. As an example, a sequential FEMHBEM
approach to calculate the dynamic behavior and sound radiation of
rolling tires is outlined in detail. The equations of motion for the wheel
are developed in the frame of an Arbitrary Eulerian Lagrangian description
with a time-independent formulation for steady state rolling and a spatial
description of vibrations. The noise radiation caused by the vibration modes
is computed by the symmetric hybrid boundary element method.
1 Introduction
There is considerable need for reliable simulations of automotive noise in
the design phase because necessary measures can be taken in time, rather
