| | 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. |
