| Abstract: | The paper presents results of numerical and experimental investigations into the vibrations of thin-walled structures, considering
such their features as the complexity of geometry, the laminated structure of walls, the anisotropy of materials, the presence
of stiffeners, and the initial stresses. The object of the study is the sounding board of an acoustic guitar, the main structural
material of which is a three-layer birch veneer. Based on the finite-element method, a corresponding calculation model is
created, and the steady-state regimes of forced vibrations of the sounding board are investigated. A good correspondence between
calculation results and experimental data is found to exist.
