摘 要: 为了探究影响磁敏弹性体压缩力学性能的因素,制备了4种不同磁敏颗粒含量以及磁敏颗粒随机分布、磁敏颗粒成链分布的磁弹体,在材料试验机的基础上附加磁学模块开发了一套力磁耦合测试系统,对磁弹体进行准静态压缩实验研究.实验结果表明:在磁场强度一定的情况下,磁敏颗粒含量越高的磁弹体压缩模量越大;磁敏颗粒含量相同的磁弹体的压缩模量随着实验磁场强度的增加而增加;磁敏颗粒成链分布的磁弹体的压缩模量随磁场强度增长的幅度大于磁敏颗粒随机分布的磁弹体的增长幅度.

Abstract:In order to explore the factors affecting the compressive mechanical properties of magnetorheological elastomers,four kinds of magnetorheological elastomers with different carbonyl iron powder mass fractions were prepared.Carbonyl iron powder with random distribution and chain-like distribution's magnetorheological elastomers were also prepared.The magneto-mechanical coupling test system was developed by adding magnetics to a material testing machine.A quasi-static compression experiment on magnetorheological elastomers was conducted.The experimental results show:with the same magnetic flux density,magnetorheological elastomers with larger carbonyl iron powder mass fraction have larger compressive modulus;with the same carbonyl iron powder mass fraction,the compressive modulus of magnetorheological elastomer increases along with the increase of the experimental magnetic flux density;the compressive modulus of magnetorheological elastomers with chainlike distributed carbonyl iron powder increases more quickly than magnetorheological elastomers with random distributed carbonyl iron powder,along with the increase of the experimental magnetic flux density.
