Abstract |
|
We study the vibration and acoustic responses of the ABH-type FG sandwich plates with dynamic resonators. Based on the first-order shear deformation theory and the acoustic theory, the dynamic governing equation and the acoustic formula of the structure are derived. The Rayleigh–Ritz method is used to solve the vibro-acoustic responses. The accuracy of the theory is proved by the finite element results, and then the effects of variable thickness forms and the parameters related to additional oscillators on the acoustic responses of ABH-type superstructure plates are discussed. It is shown that the single-layer variable thickness and the placements, numbers, connections of additional oscillators cause the acoustic response curves greater changes. The research advances the comprehension of localized responses, and vibro-acoustic response of the system can be adjusted by changing the oscillators of the superstructure, especially the parallel oscillator. |
