摘　　要：The damping property of magnetorheological elastomers(MREs) is characterized by a modified dynamic mechanical-magnetic coupled analyzer.The influence of external magnetic flux density,damping of matrix,content of iron particles,dynamic strain and driving frequency on the MREs' damping was investigated experimentally.The results indicate that the MREs' damping property depends on the interfacial slip between the inner particles and the matrix.Different from the general composite materials,the interfacial slip in MRE is affected by the external applied magnetic field.The damping property of magnetorheological elastomers (MREs) is characterized by a modified dynamic mechanical-magnetic coupled analyzer.
