| Abstract: | This paper presents a multi-frequency analysis of non-linear dynamics in a double circular plate system. The original series
of the amplitude–frequency and phase–frequency graphs as well as eigen forced time functions–frequency graphs are obtained
and analyzed for stationary resonant states. The series of the frequency characteristic of the forced time non-linear harmonics
are presented first. The analyses identify the presence of singularities and triggers of coupled singularities, as well as
resonant jumps. |
