 Summary:
 In this paper is simulated motion of the 1D model at low frequencies of moving an external excitation. The external excitation is imposed by two equal amplitudes of displacement (Ω1=Ω2=0) which is particularity of this research. Using the FFT and IFFT transformation algorithms, the amplitude of displacement are treated in the frequency and time domain, which in the final response solution correspond with the transmission function (I.M.Miličić, 2015). On the basis of the simulated simulations for a possible "motion" case, there is a displacement in the system controlled by the stiffness of the model – the structure.
