The paper presents a method for predicting dynamic and vibro-acoustic loading based on a dynamic system modal representation. The method consists in determining modal parameters (natural frequencies and eigen forms, damping coefficients) knowing frequency characteristics, calculated either by using mass distribution, stiffness and damping matrices or experimentally, and characterized by taking into account the nonlinear properties of various system elements when generating perturbance source.
