Implementation and testing of a numerical tool for the prediction of mechanical and acoustic performances of sandwich panels

摘要

Present work focuses on the implementation of a numerical procedure aimed at the structural and acoustic performances of a composite sandwich panel. The procedure involve the merge of a commercial FEM tool, mainly used for the evaluation of the static and dynamic properties of the structure, and a numerical procedure dedicated to the evaluation of the acoustic trasmission loss properties. Both procedures, as well as the sandwich pre design, are supervised by a dedicated code that also take in charge the comparison of computed parameters with the target one and manage the successive optimization loop.
