摘要
本文应用NOPD技术设计了一种复合多层板,按照四边固定薄板结构的模态振型,对不同的NOPD填充形式,进行声学实验,来评价不同填充形式在降低板类结构声辐射方面的效果,分析了该类板结构声振耦合的关系并验证了NOPD技术对声辐射控制的作用。
In this paper, the NOPD technology is applied to design a kind of complex multilayer plate. According to the modal of four sides fixed sheet structure, several experiments are completed to evaluate the effect of restraining the plate's sound radiation, analyze the coupling relationship of sound and vibration and validate the effect that NOPD technology control the sound radiation for different filled shape of NOPD.
