Abstract
Vibroacoustic behaviour analysis of large structures coupled with cavities, like those used in
common transport vehicle (aircraft, autobus, train,...), may leads to very large numerical
systems to be solved. To avoid enormous time computation, a numerical sub-structure
technique is needful. In this framework, initially we propose an approach which takes into
account, in the beginning, the structural part of the problem. It consists of a method which
subdivides the global structure into elementary cells. Each cell is described by a finite
elements method taking into account its physical properties. A similar method is used for the
global cavity which is partitioned into elementary sub-domains computed by a fini
