摘要

基于链状结构的机理模型通常用于表征磁流变弹性体(MRE)的形态,并为 MRE 的制备提供理论指导。然而,广泛使用的基于斜直链或弯曲链结构的剪切和拉伸机理模型存在表征精度不足的局限性,主要是因为从扫描电子显微镜(SEM)结果来看,各向异性 MRE 的内部颗粒链并非简单的斜直或弯曲。因此,首先要揭示 MRE 内部颗粒链的形成和颗粒相互作用机理。理论结果表明,颗粒在复杂的吸引和挤压作用下往往会形成 S 型链结构。在此基础上,提出了一种新的 "S "链机制模型,并通过与实验结果的比较,证实该模型比理想的剪切模型和拉伸模型具有更高的精确度。主要原因是 "S "链机理模型实现了剪切、压缩或拉伸模式的统一,并整合了完全耦合的磁场、分布参数和界面拉伸。S "链机理模型还考虑了 MRE 制备过程中颗粒的半径和体积分数,因此对后续制备具有更准确的指导意义。

A novel “S” chain structure mechanism model of magneto-rheological elastomer
Mechanism models based on chain-like structures are often used to characterize the morphology of magneto-rheological elastomer (MRE) and provide theoretical guidance for MRE preparation. However, widely used shear and tension mechanism models based on oblique straight chain or bent-chain structures have the limitation of insufficient accuracy in characterization, mainly because the internal particle chains of anisotropic MRE are not simple oblique straight or bent from scanning electron microscope (SEM) results. Therefore, the particle chain formation and particle interaction mechanism within MRE are revealed firstly. The theoretical results shows that particles tend to form S-like chain structures due to complex attraction and extrusion. On this basis, a novel “S” chain mechanism model is proposed, which is confirmed to have higher accuracy than the ideal shear model and tension model by comparing with the experimental results. The main reason is that the “S” chain mechanism model has realized the unification of shear, compressive, or tension mode, and integrates the fully coupled magnetic field, distribution parameters and interface stretching. The “S” chain mechanism model also takes into account the radius and volume fraction of the particles in MRE preparation, which makes it a more accurate guide to subsequent preparation.
