Abstract : This document deals with the simulation of the vibration response of a structure dipped in a supersonic flow. The vibrational excitation source is the acoustic pressure generated by the turbulent boundary layer near the wall of the structure. The mathematical formalism to describe such random pressure field is first presented. Numerical computation is then addressed through the study of the implementation of such excitation in the finite element code Abaqus. Then the particular characteristics of turbulent boundary layer noise are analyzed using a literature review. Finally, the methods of modeling and simulation presented are applied to the case of a cylinder excited by a turbulent boundary layer noise.
