| 摘 要： | 磁流变弹性体是一种磁流变材料,由高分子橡胶基体掺杂微米级的铁磁性颗粒固化而成.基于磁性物理学理论,从磁流变弹性体在磁场作用下铁磁性固体颗粒极化成链的微观结构出发,探讨磁流变流体中固体颗粒间的相互作用机理,分析研究颗粒间的相互作用力,建立了一种微观力学模型,可用于分析磁流变流体在外加磁场作用下剪切模量及其影响因素的作用效果,揭示磁流变效应的微结构机理,为磁流变弹性体的性能优化、工程开发及应用提供理论依据.

| Abstract: | Magnetorheological elastomer (MRE) is a new kind of Magnetorheological material,which are mainly composed of polymer rubber and micron-sized magnetizable iron particles. Based on the magnetomechanics,the microstructure of chains consisting of polarized particles,and the interaction between particles,the shear stress distribution contributed by a single chain of polarized particles is formulated,and then the yield stress of magnetorheological elastomer is obtained under the assumption that the distribution o... |
