摘要/Abstract

摘要：用迭代方法研究了磁流变体中体心立方结构、面心立方结构及简立方结构3种立方格子导电球的有效磁导率与磁导率比、趋肤深度及频率的依赖关系.结果发现：3种立方格子结构的导电磁球的有效磁导率为一复数，在临界体积比时，3种结构中，面心立方结构的有效磁导率最大，计算结果与文献[10-12]的实验结果符合较好.

Abstract: Relations between effective magnetic permeability of body-centered cubic,face-centered cubic and simple cubic lattices of conducting spheres and ratio of magnetic permeability,frequency are studied.The result shows that effective magnetic permeability is a complex number,and face-centered cubic lattices has the biggest magnetic permeability among the three cubic lattices in the limit of critical volume fraction;in other words,face centered cubic lattice is the most steady structure of the three cubic lattices.The conclusion of the numerical calculation is in good agreement with experimental results in refs. [10-12].

Key words: magnetorheological fluids, conducting spheres, effective magnetic permeability
