Análise dinâmica de uma guitarra elétrica de corpo sólido por meio de simulação numérica

Abstract

The electric guitar, musical instrument which was developed in the XX century, became influential in the world’s pop culture with the rise of rock’n’roll and persists as a big impression of the culture in the music. In the instrument production, the material choice is based on the experience and the manufacturer’s history, there is a paradigm that the best way to manufacture a guitar is using the materials that have always been used, without any solid scientific method that supports the material chosen. The project team saw the opportunity to act by comparing the materials that have been used in a solid-body guitar confection by dynamic analysis. It was developed a simplified electric guitar computational model and it was done modal, harmonic and transient analysis using finite elements method in the Ansys software. The results showed differences in the guitar dynamic behavior among the wood species Maple, Mahogany, Basswood, Cottonwood.
