The purpose of this research was to create a methodology for adopting the structure of a naval propulsion plant, by an estimate of noise.
To choose the best way to approach, first of all, it was performed a study on a simple physical model which consists of a flat plate structure in U. In order to perform the static energy analysis it is formulated a set of equations of power flow for this structure.
Vibro-acustic shipboard pollution is a very important issue for all classification societies prestigious as it may negatively affect both resistance vessel structure (shell and bone) influence the safety equipment on board and work and health staff on board.
In accordance with the rules of classification societies, vibro-acoustic levels on board must not exceed specific maximum values allowed.
