摘要：
The differential equations of the axisymmetric large amplitude free vibration are derived for circular sandwich plates, which under static and live load. The periodical solutions are obtained by use of Lindstedt-Poincare perturbation methods. It is nonlinear primary resonance for circular sandwich plate. The changing of initial deflection, stiffness K and a harmonic force which can affect kinetic characteristic of configuration was researched. The nonlinear primary resonance for circular sandwich plate may come with multibranched and jumping phenomenon
