Flow noise is a major noise source in the transportation industry from the automotive up to the aircraft industry. The characterization of the aerodynamic excitations and of the structure transmission is of primary interest in order to improve the passenger and crew comfort. One important component of the flow noise excitation comes from the wall pressure fluctuations induced by the development of turbulent boundary layers around the vehicle. This master thesis is focused on the validation of a method to calculate structural vibrations based on aerodynamic data by the comparison with experimental data. The analysis will be done with a flat plate configuration in a wind tunnel. The strategy yields good results and it has been validated: it could be used for more complex problems.
