This thesis presents a study of the vibrational behaviour of the violin top plate and explores the possibility of using composite materials as a substitute for traditional wood in making top plates. Numerical simulations and experimental tests are compared to validate the results. The two most popular methods for numerical and experimental vibrational analysis, the Finite Element Method (FEM) and Experimental Modal Analysis are used, respectively. The vibrational behaviour of a spruce top plate is first studied by the two methods. The results show high coherence. Then the same modeling and testing techniques are applied on two composite plates. Results show that the vibrational behaviour of composite plates differs significantly from traditional wooden plates. Thus, suggestions for further improvement of the composite top plates are given. / Cette these propose une etude sur le comportement vibratoire de la table d'harmonie duviolon et explore la possibilite d'utiliser des materiaux composites comme un substitut pourle bois traditionnel dans la fabrication des tables d'harmonies. Des simulations numeriqueset des tests exprimentaux sont compares pour valider les resultats. Les deux methodes les plus populaires pour l'analyse vibratoire numerique et experimentale, la methode des elements nis (FEM) et l'analyse modale exprimentale sont utilises, respectivement. Le comportement vibratoire d'une table d'harmonie en epicea est d'abord etudiee par les deux methodes. Les resultats montrent une coherence forte. Puis la modelisation et même des techniques de test sont appliques sur deux plaques composites. Les resultats montrentque le comportement vibratoire de table d'harmonie composites differe sensiblement de plaques traditionnels en bois. Ainsi, des suggestions d'amelioration des tables d'harmonie composites du dessus sont donnes.
