Optimalizace částí rezofonické kytary

Abstract

The master thesis deals with the optimization of resophonic guitar parts. This master thesis describes the development of the instrument from its history to the present, including a description of its current imperfections. It solves the problem of the tailpiece strength and the ideal thickness of the resonator cone in combination with an optimized spider bridge. The tailpiece was subjected to both analytical calculations and FEM static analysis, the results of which were used to proposal changes to the materials used in its manufacture, as well as alternative methods of modifying its design. The resonator assembly was subjected to both FEM static and modal analysis, the results of which were used to recommend optimum thicknesses for the resonator cone plate. The spider bridge was topologically optimized and by using it the modal analysis showed better results, based on which the ideal combination of the resonator cone sheet thickness and the optimized spider was found. This thesis offers new possibilities in increasing the strength, reducing the weight and improving the resonance behavior of selected parts of a resophonic guitar.
