中文摘要：
磁流变弹性体是磁流变液的一种固体模拟,目前的磁流变弹性体普遍存在磁流变效应不高的问题,限制了它在工程上的应用。针对羰基铁粉中C元素含量对羰基铁粉最大磁导率的影响,从而研究羰基铁粉C含量对磁流变弹性体磁流变效应的影响。采用硅橡胶为基体和具有不同C含量的羰基铁粉制备同组分磁流变弹性体,通过改进的动态机械分析仪来测试所制备样品的磁致模量,最后的实验数据分析结果表明,羰基铁粉的C含量越低,所制备的磁流变弹性体的磁流变效应越高。
英文摘要：
Magnetorheological elastomer（MRE）is the solid analog of MR fluid, there are several problems limit the practical application of MRE,such as low MR effect. According to the fact that carbon content of carbonyl iron powder（CIP）affect the maximum permeability of CIP, this paper studies the influence of carbon content of CIP on MR effect of MRE. The MRE samples are fabricated by silicone rubber and CIP with different carbon content. A dynamic mechaical analyzer is modified to characterize dynamic mechanical properities of MRE samples. Experimental result shows MR effect has an increasing tendency with the decreasing of carbon content.
