Abstract

In the activities planned for a national research project, a benchmark for the vibro(acoustic) predictive methodologies has been assembled. It is represented by three aluminum plates joined along the edges through angular beams. Against experimental measurements, the standard finite element method and the application of scaled finite element model will be tested. Some finite element models will be classified so that each of them is associated with different wave propagation hypothesis. The comparison will start from the local validation, single point frequency response for a specific excitation, to a more global one mean structural response, for a random excitation in a selected frequency band. The last one is a representation of the system 'a la S.E.A.'. The results will give an insight of the possible application of the finite element method toward the statistical energy analysis, along with a proper definition of each evaluation step.
