Description
  • Práce se zaměřuje na popis pohybu teploty a vlhkostni v materiálu rezonanční desky klavíru. K popisu je užito programu ANSYS využívajícího metody koneřných prvků (MKP). Je sestaven obecný parametrický model (geometrický, fyzikální, konečně-prvkový) a následně provedena teplotní analýza, vlhkostní analýza a analýza pohybu vázaných polí. Je sledován vliv vybraných faktorů na chování desky. Výsledkem jsou především rozložení teplot a vlhkostí, ale rovněž napětí a deformace desky jako odpověď desky na studovaná rozličná zatížerní. (cs)
  • This work focuses on description of thermal and moisture distribution in material of grand piano soundboard. Finite-element method (FEM) in utilize by computing system ANSYS is used. General parametric model of soundboard - geometric, physical and mathematical (finite-element) model - is built in environment of system, in consequence thermal analysis, moisture analysis and also coupled-field analyzes are performed. Full parameterization, prescription of models building and solution of problems are made in APDL (Ansys parametric design language). Selected factors influence on behavior of board is monitored by changing of model's parameters. Results are distributions of physical fields (temperatures, moisture, stresses) and strains of board as a reaction to different loadings.
