Análisis Numérico y Experimental del Comportamiento Dinámico de un Violín

Abstract

A numerical and experimental study of the plates of a violin was made, taking into account the effect that different physical and mechanical factors produce on their dynamic response.
Experimental tests were conducted to determine the vibrational modes, along with the resonant frequencies, of the cover of a violin. A numerical model of the board by means of the finite element method was made, to determine the influence of the different mechanical and geometric properties on its vibrational modes and frequencies; finding methods that allow to make changes in their structure with the purpose of obtaining the expected acoustic response. Modifying the
distribution of thicknesses or varying the arching, different effects were obtained on the frequencies and the vibrational modes.
