Abstract. . The paper focus on elastic and dissipative nonlinear
dynamic systems subjected to external harmonic disturbing forces. Thus,
the correlation between the nonlinearity degree and time harmonic response
in terms of frequency with high-order harmonics as related to the excitation
harmonic is pointed out.
DINAMIČKI ODGOVOPR NELINEARNOG SISTEMA
POD DEJSTVOM STACIONARNE HARMONIJSKE POBUDE
Rad je usmeren na nelinearne dinamičke sisteme sa elastičnim i disipativnim
elementima, a koji su porvrgnuti spoljašnje harmonijske pobudne sile. Istraživana
je korelacija izmedju stepena nelinearnosti i vremena harmonijskog odziva
u funkciji frekvencije sa harmonicima višeg reda u odnosu na harmonike
spoljašnje pobude.
