This tutorial will aim at providing the attendees with a sound basis for efficiently adressing structural vibrations originating from acoustic pressure fluctuations, namely : airbone vibrations.
While the field of structure-borne-sound is relatively well covered, the converse is not true. One obvious reason is that airborne vibrations can usually be ignored, unless sound pressure level are considerable, or if admissible vibrations amplitudes are very small.
In the first case, typical of aerospace launchers or power generation industry, detailed simulations are conducted and further validated via testing. or, when configurations are similar enough for project-to-project deviations to be remain minimal, they can be handled via design-by-rule procedures. For particularly demanding precision engineering tasks however, the allowable levels can be extremely small, while geometries and mechanical configurations are be highly diverse, ranging from slender (vibration immune) supports to large (vibration prone) enclosures .
Overall, for the precision engineer, there is a need for recognizing situations where acoustic induced vibrations are indeed significant, and in such situations, how to best control them.
And the end of the tutorial, it is expected that the attendees should be equipped with clear notions about how acoustics waves might disturb a given system, how to quantify their contribution and when required, what are the technical options for mitigating the problem at hand.<\/p>\n\n\n\n
