Abstract:
The damping property of magnetorheological (MR) elastomers is characterized by a modified dynamic mechanical-magnetic coupled analyzer. The influences of the external magnetic flux density, damping of the matrix, content of iron particles, dynamic strain, and driving frequency on the damping properties of MR elastomers were investigated experimentally. The experimental results indicate that the damping properties of MR elastomers greatly depend on the interfacial slipping between the inner particles and the matrix. Different from general composite materials, the interfacial slipping in MR elastomers is affected bythe external applied magnetic field.
Key words:  Magnetorheological elastomers, Damping property, Interfacial slipping

摘要:
利用改装后的力磁耦合动态测试系统实验研究了磁流变弹性体在磁场下的阻尼性能. 实验得出了外加磁场的磁感应强度、基体的本征阻尼、铁粉含量、动态应变以及激励频率对磁流变弹性体阻尼的影响规律. 发现了磁流变弹性体的阻尼在很大程度上是由基体和颗粒之间的界面滑移所决定的. 而且该界面滑移不同于一般复合材料,它会受到外加磁场的影响..
