摘要
现阶段磁流变弹性体的本构关系的研究依然是个很大的难点。本文考虑不同加载条件下磁流变弹性体的磁致力学性能,引入复杂网络分形理论,考察磁流变弹性体磁性颗粒复杂网络的分形特征与磁流变弹性体的磁致力学性能的一般规律。结果表明,磁流变橡胶的磁致模量峰值的出现与磁性颗粒网络的分形维数有关,与磁场强度大小无关。
At present, constructing constitutive relations is still a difficulty for magneto-rheological elastomers. In this paper, magneto-induced modulus of MREs were studied under different conditions. And the association of the magneto-induced modulus and Fractal features parameters of MREs was studied by introducing the fractal theory of complex networks. The results show that the existence of peak value of the magneto-induced tensile(compression or shear) modulus of the magneto-rheological elastomers is related to the fractal dimension of the magnetic particles network and has nothing to do with the magnetic field.
