AB The subject of this paper is description of building of general parametric model of grand piano soundboard in environment of software ANSYS. Parametric utilization of APDL (Ansys Parametric Design Language) was made in full range of this component. Physical model description includes orthotropic linear elasticity material and prescribed boundary conditions of solution of basic structural analysis (modal analysis). Main idea of this work rest in offering of model which allows simple changes of numerical simulation by changing of basic model parameters. This model allows monitoring of selected factors (changes in construction and material composition) which may influence the dynamic behaviour of board. In addition to general model there are presented also results of simulations which describe properties of board in frequency domain for factual type of soundboard.
