 Summary:
 In this paper is, imposed 1D dynami\c model with a resistance, of substrate excitation in domain of low frequency. Excitation with two different frequencies of displacement amplitudes (Ω1≠Ω2≠0) are mathematically modeled and is a specificity of this research. Applying the Fourier transformations of the treated displacement amplitude in the frequency and time domain are showed that they are mapping proposed by the transfer function (I.M.Miličić, 2015). Constructed computer simulations confirmed displacement of structural systems at lower frequencies of external excitation controls stiffness.
