基于差分进化算法的并联腔型超构吸声材料的结构设计
Structural Design of the Parallel-cavity-type Sound Absorption Metamaterials Based on the Algorithm of Difference Evolution
摘要
Abstract
A new design method was proposed to design the structural parameters of the cavity-type sound absorbing metamaterial composed of multiple embedded tube Helmholtz resonant sound absorbing elements in parallel connection.This design method established the optimal mathematical model with the structural thickness of the sound absorbing metama-terial as the optimization objective.Moreover,the difference evolution(DE)algorithm in the Geatpy library was called by Python language to optimize the solution,so as to effectively realize the reverse design of the structural parameters of the sound absorbing metamaterials.The reliability and robustness of this design method were verified by experiments,simula-tions,and various forms of DE comparative analyses.关键词
