Internal character of the quasi-periodic response near the resonance of a single non-linear system

Popis výsledku v původním jazyce

The exact coincidence of external excitation and basic eigen-frequency of a single degree of freedom (SDOF) non-linear system produces stationary response with constant amplitude and phase shift. When the excitation frequency differs more or less from the system basic eigen-frequency, various types of quasi-periodic response occur having a character of a beating process. The period of beating changes from infinity in the resonance point until a couple of excitation periods outside the resonance area. The shape of the response amplitude envelope within one quasi-period changes from a constant (stationary process) dramatically when the frequency distance from the resonance is rising. The ratio of energy content of quasi-periodic and stationary componentis decreasing in the same time. Starting a certain frequency the quasi-periodic part fully vanishes and the stationary part absorbs the whole response energy. The above phenomena have been identified qualitatively in many papers including
