In this Master of Science thesis, resulting from the cooperation between the Department of Mechanical, Nuclear and Production Engineering of the University of Pisa and Dallara Automobili s.p.a., the target was the design of a graphical user interface, in Matlab, for signal processing. The signals to be processed were acquired during modal tests aimed at detecting natural frequencies of wings of a high-performance single-seater sports car produced by Dallara. Afterward, these frequencies were compared with the frequencies of forcing functions due to the motion of the vehicle, in order to avoid the dangerous occurrence of resonances
