基于分布链修正的磁流变弹性体的物理模型

Revised Model of the Magnetorhelogical Elastomer Based on Distributed Chains

摘要: 在考虑磁流变弹性体中链的方向分布的基础上,对磁流变弹性体的偶极子模型作出了修正.用局部场的方法计算了链的势能,引入了分布函数来描述链的分布,并分析了与磁场方向不一致的斜链的磁流变效应,进而通过积分叠加求得含有分布链的磁流变弹性体的磁流变效应.在磁流变弹性体的理论模型中,引入了制备磁场和基体性质等影响因素.

Abstract: On the basis of distributed chains, the model of MR elastomer was revised. After the potential energy of a chain was analyzed using the local field method, a special function was used to describe the distribution of chains. Then the MR effect of distributed chains as well as the overall MR effect were studied. Concurrently, the effects of the curing magnetic field and the matrix were incorporated into the model of MR elastomer.
