Analyses of dynamic response and sound radiation of sandwich plate subjected to acoustic excitation under thermal environment

摘要: In this paper, the dynamic response and sound radiation of sandwich plate subjected to an acoustic excitation under thermal environment are analyzed. The is a uniform temperature load. Thermal stress considered as membrane force in plate, while change material property due load ignored. applied on assumed be plane wave. Coupling structural vibration medium considered. equivalent non-classical theory, which takes effects rotational inertia shear deformation into account, utilized get analytical solutions. caused by discussed. It found that rise decreases natural frequencies moves peaks low-frequency range. doesn’t influence characteristics but incident angle relative number evident curve. comparisons results those computed VA one show accuracy theoretical method.
