Rheological Properties of Magnetorheological Gel

  • 摘要: 研制了一种新型的磁流变胶,通过稳态和动态剪切试验对其流变性能进行了测试.结果表明:在较大磁场作用下磁流变胶的剪切应力对剪切率的依赖性很小,并具有较大的剪切应力;其线性粘弹性区域随着外加磁场的增大而变宽;其储能模量G′在外加磁场作用下可以达到7.98 MPa(H=102.8 kA·m-1),并且与磁流变液一样在外加磁场作用下其G′曲线也出现了三个明显的变化区域.
    Abstract: A new type of magnetorheological gel (MRG) was prepared and its rheological properties were examined.The results showed that shear stress of the MRG was insensitive to shear rate when the applied magnetic field strength was large and its linear viscoelastic range was enlarged by the increase of applied magnetic field strength.Its storage modulus reached 7.98 MPa when the applied magnetic field was H=102.8 kA·m-1.Just like magnetorheological fluids,three characteristic regions were observed in MRG.
