Wave field of sounding board in dependence on geometrical and physical parameters

The paper presents the computation technique and the results of numerical analysis of wave fields of sounding board. Vibrations of the structure are excited by normal harmonic force. Frequency range up to 1000 Hz is considered. The vibration field of structure in dependence on geometrical and physical-mechanical characteristics is studied. On the basis of the analysis it is stated that the anisotropy of physical-mechanical properties of the structure and complexity of geometrical form provide more uniform distribution of vibration energy in frequency range.
