Nonlinear Primary Vibration of Circular Sandwich Plates and Modal Analysis
The nonlinear forced vibration of damped circular sandwich plates is studied. From the movement equations of circular sandwich plate expressed in displacement components, got the relevant nonlinear vibration equation by Galerkin method. The changing of initial deflection, stiffness and a harmonic force which can affect kinetic characteristic of configuration was researched. The FRF of primary resonance periodical solutions were obtained, synchronously modal analysis experiment for composite material plates were tested.
