Abstract

Magnetorheological (MR) elastomer composites, comprising soft silicone rubber, various additives, and different weight fractions of carbonyl iron particles (CIPs) coated with silane coupling agent, are produced via a novel manufacturing process in an anisotropic state. This study encompasses both experimental and modeling investigations into the dynamic viscoelastic properties of magnetorheological elastomer (MREs) in shear mode under varying magnetic fields, displacement amplitudes, and frequencies. Two MRE vibration mitigation devices are fabricated to experimentally assess the shear storage modulus and the loss factor of MREs. The experimental findings reveal a pronounced MR effect in the MRE devices, where both the shear storage modulus and the loss factor increase with rising magnetic fields, frequencies, and particle weight fractions, yet decrease with higher displacement amplitudes. A modified fractional-derivative equivalent parametric model, grounded in a magnetic field- and frequency-dependent shear modulus model along with internal variable theory, is proposed to describe the effects of these key influencing factors on the MREs’ dynamic viscoelastic properties. Comparative analysis of experimental and numerical data demonstrates that this refined mathematical model can accurately represent the dynamic viscoelastic properties of MREs.

含硅烷偶联剂涂层羰基铁颗粒的磁流变弹性体的实验和理论研究

磁流变（MR）弹性体复合材料由软硅橡胶、各种添加剂和涂有硅烷偶联剂的不同重量分数的羰基铁颗粒（CIPs）组成，通过一种新型制造工艺在各向异性状态下制成。本研究包括磁流变弹性体（MREs）在不同磁场、位移幅度和频率下剪切模式的动态粘弹性能的实验和建模研究。我们制作了两个磁流变弹性体减震装置，以实验评估磁流变弹性体的剪切存储模量和损耗因子。实验结果表明，MRE 装置具有明显的磁共振效应，剪切存储模量和损耗因子均随磁场、频率和颗粒重量分数的增加而增加，但随位移振幅的增大而减小。我们提出了一个基于磁场和频率相关剪切模量模型以及内变量理论的修正分数派生等效参数模型，用于描述这些关键影响因素对 MRE 动态粘弹特性的影响。对实验数据和数值数据的对比分析表明，这一完善的数学模型能够准确地表示 MREs 的动态粘弹特性。

期刊介绍： Smart Materials and Structures (SMS) is a multi-disciplinary engineering journal that explores the creation and utilization of novel forms of transduction. It is a leading journal in the area of smart materials and structures, publishing the most important results from different regions of the world, largely from Asia, Europe and North America. The results may be as disparate as the development of new materials and active composite systems, derived using theoretical predictions to complex structural systems, which generate new capabilities by incorporating enabling new smart material transducers. The theoretical predictions are usually accompanied with experimental verification, characterizing the performance of new structures and devices. These systems are examined from the nanoscale to the macroscopic. SMS has a Board of Associate Editors who are specialists in a multitude of areas, ensuring that reviews are fast, fair and performed by experts in all sub-disciplines of smart materials, systems and structures. A smart material is defined as any material that is capable of being controlled such that its response and properties change under a stimulus. A smart structure or system is capable of reacting to stimuli or the environment in a prescribed manner. SMS is committed to understanding, expanding and dissemination of knowledge in this subject matter.
