Modal Analysis of Soundboard of the Upright Piano by FInite Element Method (FEM)

Popis výsledku v původním jazyce

This work is engaged in the study of the change eigenfrequencies and eigenmodes of vibration of soundboard of the upright piano owing to change of material qualities (density,module of elasticity, spiro grain), change of geometry (slab thickness, ribs proportions, ribs number, bridges form) and the way of anchoring. Modal analysis was made by finite elements method in computer program ANSYS. Analysis model was arranged parametricaly by the help of script tongue APDL what allowed the construction of probabilistic design system sequence. The results describe influence of density and longitudinal module of elasticity of material with eigenfrequencies of board. Effect of spiro grain in cross plane appears like least relevant. Generally supposed influence of change of geometry and density with eigenfrequencies was more closery described for soundboard of upright piano. It follows from the research that values of eigenfrequencies grow with increasing of implasticity system what is incurred b
