本文介绍了图像化磁流变（MR）弹性体的分析、制备和表征。考虑磁流变体的局域磁场和粒子相互作用磁能，对晶格和BCC结构磁流变体的磁场依赖力学性能进行了理论分析和数值模拟。在聚二甲基硅氧烷（PDMS）基体中组装软磁颗粒，制备出具有均匀晶格和BCC结构的新型磁流变弹性体，并用显微镜对其进行了观察。利用平行板磁流变仪对新型磁流变体的场相关模量进行了表征。实验结果与数值模拟结果吻合较好。
This paper presents analysis, fabrication and characterization of patterned magnetorheological (MR) elastomers. By taking into account the local magnetic field in MREs and particle interaction magnetic energy, the magnetic-field-dependent mechanical properties of MREs with lattice and BCC structures were theoretically analyzed and numerically simulated. Soft magnetic particles were assembled in a polydimethylsiloxane (PDMS) matrix to fabricate new MR elastomers with uniform lattice and BCC structures, which were observed by a microscope. The field-dependent moduli of the new MR elastomers were characterized by using a parallel-plate MR rheometer. The experimental results agreed well with numerical simulations.
