| Abstract |
According to the requirement of noise reduction in low frequency, the upper panel and the corrugated structure of the sandwich plate with corrugation and auxetic honeycomb hybrid core are
perforated to form the sound absorption structure of the microperforated sandwich plate, so that the
sound can enter the structure which has excellent broadband sound absorption characteristics. Here a theoretical model of the sound absorption performance of microperforated sandwich plate with
hybrid core under vertically incident plane wave is established by using classical sound absorption theory. The calculated sound absorption coefficient is calculated and validated by the finite element
(Comsol) simulation. Then, the effects of structural parameters and microperforation parameters on the sound absorption behavior are analyzed and discussed. On this basis, the standard genetic algorithm is used to optimize the microperforated sandwich plate with hybrid core. |
