Based on the local resonance theory, a structural model of a new type of vibration reduction material—metaconcrete was proposed, and the band gap number of the metaconcrete cell was increased by increasing the type of resonant aggregates in the matrix. Firstly, the energy band structure, eigenmodes and attenuation characteristics of single, double, and three resonant aggregate metaconcrete cell were calculated by the finite element method. Secondly, the generation mechanism and the influence law of band gap were studied. Finally, the band gap estimation formula was derived base on the effective mass theory. The results showed that the metaconcrete cell exhibited band gap properties, and with the increase of the types of resonant aggregates in the matrix, the band gap number increases but each band gap width decreases. Moreover, there is a one-to-one correspondence between the types of resonant aggregates and the band gaps. The starting frequency of the band gap was determined by the translational vibration of the corresponding primitive cell scatterers, while the cut-off frequency was determined by the reverse vibration between the corresponding primary cell scatterers and other units. By properly configuring the material and geometric parameters of the primitive cell, the position and width of the corresponding band gap can be optimized. The band gap calculations from the effective mass theory agreed well with the finite element method, and it can be used to obtain the band gap of the multiple resonant aggregates metaconcrete cell.

基于局域共振理论,提出了一种新型减振材料—混凝土超材料的结构模型,并通过增加基体中谐振骨料的种类,增加了元胞的带隙数量。利用有限元法,对比分析了单、双以及三谐振骨料混凝土超材料元胞的能带结构、本征模态和衰减特性,研究了带隙的产生机理和影响因素,根据等效质量法推导了带隙计算式。结果表明:混凝土超材料元胞具有带隙特性,且随着基体中谐振骨料种类的增加,带隙数量增多,但每条带隙的宽度降低,谐振骨料种类与带隙之间存在一一对应的关系;带隙的起始频率由对应元胞散射体的平移振动决定,而截止频率则由对应元胞散射体与其他所有单元之间的反向振动决定;通过合理配置元胞的材料和几何参数,可以优化带隙的位置和宽度;等效质量法的带隙计算值与有限元法吻合良好,可用于多谐振骨料混凝土超材料元胞的带隙计算。

基于局域共振理论,提出了一种新型减振材料—混凝土超材料的结构模型,并通过增加基体中谐振骨料的种类,增加了元胞的带隙数量。利用有限元法,对比分析了单、双以及三谐振骨料混凝土超材料元胞的能带结构、本征模态和衰减特性,研究了带隙的产生机理和影响因素,根据等效质量法推导了带隙计算式。结果表明:混凝土超材料元胞具有带隙特性,且随着基体中谐振骨料种类的增加,带隙数量增多,但每条带隙的宽度降低,谐振骨料种类与带隙之间存在一一对应的关系;带隙的起始频率由对应元胞散射体的平移振动决定,而截止频率则由对应元胞散射体与其他所有单元之间的反向振动决定;通过合理配置元胞的材料和几何参数,可以优化带隙的位置和宽度;等效质量法的带隙计算值与有限元法吻合良好,可用于多谐振骨料混凝土超材料元胞的带隙计算。

Based on the local resonance theory, a structural model of a new type of vibration reduction material—metaconcrete was proposed, and the band gap number of the metaconcrete cell was increased by increasing the type of resonant aggregates in the matrix. Firstly, the energy band structure, eigenmodes and attenuation characteristics of single, double, and three resonant aggregate metaconcrete cell were calculated by the finite element method. Secondly, the generation mechanism and the influence law of band gap were studied. Finally, the band gap estimation formula was derived base on the effective mass theory. The results showed that the metaconcrete cell exhibited band gap properties, and with the increase of the types of resonant aggregates in the matrix, the band gap number increases but each band gap width decreases. Moreover, there is a one-to-one correspondence between the types of resonant aggregates and the band gaps. The starting frequency of the band gap was determined by the translational vibration of the corresponding primitive cell scatterers, while the cut-off frequency was determined by the reverse vibration between the corresponding primary cell scatterers and other units. By properly configuring the material and geometric parameters of the primitive cell, the position and width of the corresponding band gap can be optimized. The band gap calculations from the effective mass theory agreed well with the finite element method, and it can be used to obtain the band gap of the multiple resonant aggregates metaconcrete cell.
