|Abstract: ||In this paper, structural acoustic optimisation of automotive-type panels is considered. The
aim of the optimisation method used is to impose on the panel structural modes that radiate
acoustic energy weakly. In the proposed approach, the panel under consideration is isolated
from the rest of the structure and hence reduce significantly the time required for its analysis
and optimisation. The proposed method is applied specifically to the optimisation of a floor
panel of a simplified car model. To achieve weakly radiating structural modes different geometric
modifications on the panel are considered. The results show significant reduction in the
radiated sound power of the optimised panels.|
