摘要
磁流变流体因其独特的磁流变效而具有十分广泛的应用前景 ,研究磁流变效应是制造磁流变材料和开发工程应用的关键问题。作者从理论和实验两方面 ,分析和研究了磁场强度、磁性介质微粒的体积百分比浓度、介质微粒大小对磁流变效应的影响。研究表明 ,磁流变效应不仅依赖磁场强度 ,而且与磁性介质微粒的体积百分率、粒子的大小有关 ,得到了理论和实验一致的结果 ,为工程开发和制造磁流变流体提供了可靠依据 。
Magneteroheogical Fluids have very wide application due to the particular magneteroheogical effect. It is the key to develop ment of magneteroheological fluids and application to research on the magneteroheological effect. This paper discusses the magnetorheological effect for Magnetorheological (MR) fluids from the view of theory and experiment. It describes the influence of the applied magnetic field, volume fraction of the particles and the size of the magnetic particles on the rheological effect of MR fluids. It is shown that the experiment result agrees with the theoretic one. That provide the basis for the engineering development and the engineering applications.
