Chaotic Dynamics of Non-Autonomous Nonlinear System for a Sandwich Plate with Truss Core

Blog Article

This paper deals with the multi-pulse chaotic dynamics of a sandwich plate with truss core under transverse and in-plane excitations.In order to analyze the complicated nonlinear engine Component behaviors of the sandwich plate model by means of the improved extended Melnikov technique, the two-degrees non-autonomous system is transformed into an appropriate form.Through theoretical analysis, the sufficient conditions for the existence of multi-pulse homoclinic orbits and the criterion for the occurrence of chaotic motion are obtained.

The damping coefficients and transverse excitation parameters are considered as the control parameters to Shim;PC discuss chaotic behaviors of the sandwich plate system.Numerical results and the maximal Lyapunov exponents are performed to further test the existence of the multi-pulse jumping orbits.The theoretical predictions and numerical results demonstrate that the chaos phenomena may exist in the parametrical excited sandwich plate.
