In order to study on primary parametric resonance with primary resonance of thin rectangular plate on Winkler foundation subjected to harmonic excitation considering material nonlinearity
its nonlinear dynamical equation is established and transformed to nonlinear vibration equation based on Galerkin’s method. By using the method of multiple scales for nonlinear vibration
the approximate solution of primary parametric resonance and primary resonance of the system is acquired. Numerical computation is carried out to analyze the influences of excitation
detuning
damping
nonlinear parameters and geometric parameters on the system.
