Résumé

In this paper, acoustic enclosure for a compressor package is designed and an approach for Transfer Path Analysis (TPA) is proposed. Path Contribution and panel contribution can be seen for which path dominates over the structure. A method is presented to reduce noise by structural modifications of the enclosure. Guiding phenomenon was implemented to reduce the noise i.e. obstacles to the wave propagation were provided. The points where noise level (vibrations) was maximum, ribs and barriers were provided. The presented work can be used for similar problems involving structure-borne noise sources. The analysis work presented in the paper is done in NASTRAN.
