提出了一种基于空心钢管(hollow steel tube,HST)的“超原子”结构模型,声学透射实验和数值计算结果表明基于该模型的声学超材料可以实现负等效质量密度。为了说明空心钢管结构性质,研究了空心钢管微结构几何尺寸(例如空心钢管直径)变化时材料的透射性质,结果表明空心钢管几何尺寸的改变对声学超材料的透射禁带频率有影响。
A model of “meta-atom”structure based on hollow steel tube (HST)was presented,which could a-chieve the negative effective mass density demonstrated by the acoustic transmission experiments and numerical calculation results.The transmission properties resulted from the change of microstructure geometry of hollow steel tube were studied in order to illustrate the structural properties of the HST.The results showed that the change of the HST geometry affected the transmittance band gap frequency of acoustic metamaterials.
