 Summary:
 In this paper imposed on the 1D dynamic model of resistance substrate excitation modeling function with two frequency amplitude shift in the time domain. FFT transformations had been treated in the frequency domain response amplitudes displacement equations of motion which corresponds to the transfer function (I.M.Miličić, 2015). Two variants had been suggestions (when only the first or only the second amplitude in the resonance), and shows the comparative analysis of model behavior from the standpoint from the duration of the excitation. Two frequency response model with the proposed transfer function, the order of frequency amplitude excitation hadn’t respected as an essential factor.
