Modální analýza bubenické paličky metodou konečných prvků
Sochor, Petr
This thesis examines the issues associated with drumstick mechanical properties and possibilities of experimental methods and theoretical descriptions. Gradually, it focuses on the use of numerical methods to describe the behavior of musical instruments, especially percussion. The methodology explains the construction of a model drumstick and execution of modal analysis using a commercially available software ANSYS. The goal of the methodolgy is a comparison of natural frequencies and mode shapes for each alternative model. Design alternatives were also compared in terms of geometry, material composition and the impact on the natural frequencies and vibration shapes. The final step of this method was a creation of a modified drumstick model using composite materials.
