Abstract

A micro–nano magnetorheological elastomer (MRE) containing Fe ₃ O ₄ nanoparticles was prepared, and its mechanical properties were analyzed. A microscopic static force model was used for MREs with different concentrations of nanomagnetic particles. To investigate the mechanical properties, an experimental platform was built, and its magnetic field flux was simulated with finite-element software. The results show that the maximum compressive elastic modulus for MREs containing 10% Fe ₃ O ₄ nanoparticles is 2.89 MPa, which is 149% that of a traditional MRE under the same magnetic field. The normal stress of micro–nano MRE was significantly improved, which could be useful in the development of high-performance MREs.

微纳米磁流变弹性体的法向应力

制备了含有Fe3O4纳米粒子的微纳磁流变弹性体，并对其力学性能进行了分析。使用微观静态力模型对具有不同浓度纳米磁性颗粒的MRE进行了研究。为了研究其力学性能，搭建了实验平台，并用有限元软件对其磁场通量进行了模拟。结果表明，在相同磁场下，含10%Fe3O4纳米颗粒的磁流变材料的最大压缩弹性模量为2.89MPa，是传统磁流变材料压缩弹性模量的149%。微纳MRE的法向应力得到了显著改善，这可能有助于开发高性能的MRE。
