| Abstract: | For analyzing the dynamical stability of deck rectangular thin plate subject to harmonic excitation in temperature field, the system nonlinear dynamical equation is established based on elastic theory, and is transformed to nonlinear vibration equation based on Galerkin’s method. The stability system is analyzed by means of stability theory. By using the multiple scales method of nonlinear vibration, the approximation solution of system primary resonance is acquired. The analysis results show that the system primary resonance curve has jumping phenomenon and hard stiffness characteristic. |
