实验研究影响磁流变效应的因素

磁流变液是由导磁微粒、载液及添加剂组成的悬浮液，因其独特的磁流变效应，在液压、制动振动、驱动、密封等主动和自适应控制方面具有广阔的应用前景．研究磁流变效应是开发磁流变液、优化磁流变液性能以及开发工程应用的关键．为此，应用实验方法研究了磁场强度、微粒的磁化率、体积百分比浓度、微粒大小、添加剂等对磁流变效应的影响，表示了磁流变效应对各种影响因素的响应特性，并分析讨论了其影响机理，为工程开发和制造磁流变液提供了可靠依据，为磁流变技术的发展提供了理论基础．

Experimental Investigation on Factors for Magneteroheogical Effect

Magnetorheological(MR) fluids are the suspensions consisted of micron size magnetically polarizable particles and carrier liquid as well as some additives.They have broad potential applications such as dampers,brakes,clutches,engine mounts and so on due to their particular magnetorheological effect.This paper experimentally investigates the magnetorheological effect of Magnetorheological(MR) fluid.It shows the dependence of magnetorheological effect of MR fluid on the applied magnetic field,the particle susceptibility,the particle volume fraction,the particle size,the additive,and the confecting technology.It describes the response to these factors.The results provide the basis with developing MR fluids and engineering applications.
