Název v původním jazyce

Quasi-periodic response types of a single non-linear dynamic system in resonance and out of resonance domains

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 from the system 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 above phenomena have been identified qualitatively in many papers including authors contributions. Nevertheless investigation of internal structure of a quasi-period and its dependence on the difference of excitation and eigen-frequency is still missing. Combinations ofharmonic balance and small parameter methods are used for qualitative analysis of the system in mono- and multi-harmonic versions. They lead to non-linear differential and algebraic equations serving as a basis for qualitative analytic es
