Vibro-Acoustic Analysis of a Spherical Joint Using FEM

Résumé

Vibro-Acoustic analysis gives the possibility of obtaining the level of sound pressure depending on the frequency, as well as the evaluation of the acoustic pressure in a point of interest.
The monitoring can be done using a microphone placed in an area of acoustic sensitivity.
This paper highlights the possibility of monitoring the level of acoustic pressure in the vicinity of some structural elements that can vibrate under the action of external excitations.
The studied assembly is a spherical joint. All the changes in the acoustic pressure level on the control direction of this assembly can indicate structural changes at the level of the monitored joint, thus highlighting possible defects.
