Abstract:Nonlinear dynamic behaviors including global bifurcations and multi‐pulse chaotic dynamics of a rectangular thin plate with lumped mass subjected to a harmonic foundation excitation and in‐plane excitation are investigated in this paper. With the von Ktrueármtrueán equation and Galerkin method, the dynamic equation of the first two modes for this model is obtained. Utilized the method of multiple scales, the average equation of the system in the case of both primary resonance and 1/2 subharmonic resonance is… Show more
