摘　　要：论文通过建立水下微穿孔板有限元模型,分析比较不同的微穿孔形状和排列方式对微穿孔板透声性能的影响,并通过遗传算法对微穿孔板的几何参数进行进一步地优化,为水下微穿孔板声超材料应用于新型声导流罩设计提供参考。In this paper,the finite element model of the underwater microperforated plate is established,and the effects of different microperforated shapes and arrangements on the sound transmission performance of the microperforated plate are analyzed and compared.The geometric parameters of the microperforated plate are further optimized by genetic algorithm,which provides a reference for the application of underwater microperforated plate acoustic metamaterial in the design of new sonar dome.
