| 摘 要： | 应用有限元方法得到在不同颗粒体积比浓度条件下,磁流变弹性体在成链方向的相对磁导率和磁致剪切模量随磁场强度变化曲线。设计了一个简单的磁流变弹性体阻尼器模型,并在此基础上应用上述计算所得曲线,对该阻尼在电流和线圈匝数变化时,计算出阻尼器模型的磁致剪切模量随外加电流和线圈匝数的变化曲线。计算结果表明,磁流变弹性体阻尼器模型的磁致剪切模量随外加电流的增大而增大,随线圈匝数的增加而增加,但当电流和线圈匝数达到一定值之后阻尼器模型的磁致剪切模量趋于稳定。分析了电流和线圈匝数对阻尼器性能的影响,使阻尼器在设计阶段对其性能进行评估得以实现。

| Abstract: | By means of finite element method,the relative magnetic permeabilities and shear modulus of the magneto-rheological (MR) elastomers in the direction of chain-like structures were calculated and plotted for various particle volume fractions.Based on the results above,a simple damper model of the MR elastomers was developed and the difference of the shear modulus due to magnetic field for various current intensities and coil turns was calculated.The calculated results show that the shear modulus increases wit... |
