| | Summary: |
| | In this paper imposed on the dynamics of 1D models with resistance pad
excitation (external displacements) mathematically was modeled as a function of the two frequencies developments in the time domain. The Fourier transform algorithm applying treated amplitude displacement in the frequency and time domain, respecting the proposed transfer function a mapping "response-excitation" (I.M.Miličić, 2015). The particularity of this research theoretical mechanics, the response analysis model from the viewpoint of the duration of the excitation. Computer simulations, it was confirmed that the behavior of the structure by the action of the load (calculation of influence in girders) depends on the time its duration. |
