摘    要:运用集中质量法计算了一维铝/非金属、花岗岩/非金属声子晶体的振动带隙。结果表明:在相同条件下,铝、花岗岩与同一非金属组合成的声子晶体带隙几乎相同,而弹性模量、泊松比对带隙结构几乎无影响,带隙主要由这两种材料的密度决定。

关 键 词:声子晶体  振动带隙  集中质量法

Abstract:The vibration band gaps of one-dimensional phononic crystals of aluminum/nonmetal and granite/nonmetal are investigated by lumped-mass method.The effects of the density,elastic modulus and Poisson ratio on band gaps are discussed.The results show that the band gaps of aluminum/nonmetal(A) phononic crystals are as wide as those of granite/nonmetal(A) under the same conditions.Other parameters such as elastic modulus and Poisson ratio have almost no effects on the vibration band gaps of one-dimensional phonon...
Keywords:phononic crystals  vibration band gap  lumped-mass method
