Effects of complex load on nonlinear vibration characteristics of circular sandwich plate
The fundamental equations for nonlinear vibration of circular sandwich plate under uniformed load and circumjacent load were established, and then accordingly the exact solution of static load and its numerical results was given. Based on time mode hypothesis and the variational method, the nonlinear differential equation of the space mode is derived, and then the amplitude frequency-load character relation of circular sandwich plate was obtained with the modified iteration method. Consequently the rule with which the two kinds of load affect the vibration characters of the circular sandwich plate was investigated. When circumjacent load makes the lowest natural frequency zero, critical load was obtained.
