磁场对磁流变弹性体表面特性的影响
|
摘要
为探究磁流变弹性体在磁场作用下的表面特性,制备体积分数为5%,10%,15%,20%,25%和30%的磁流变弹性体(MRE)样本,分别在施加磁场前后进行金相显微镜、白光干涉仪表面观察实验以及滑动摩擦验证实验。表面观察实验表明:样本的表面磁性颗粒随组分体积分数的增加而增加,并且各组分样本表面在磁场下粗糙度均降低,5%MRE的样本降低最多,约20%;摩擦实验结果表明:摩擦因数随着体积分数增加和在磁场作用下均出现降低趋势,30%MRE的摩擦因数相比于5%的摩擦因数约减小了38%, MRE表面铁磁颗粒含量是影响其摩擦特性的主要因素。
To explore the influence of magnetic field on surface characteristics of magnetorheological elastomers(MREs), the MREs with volume fractions of 5%, 10%, 15%, 20%, 25% and 30% were fabricated. Then the surface observation experiments of metallographic microscope, white light interferometer and sliding friction test were carried out with magnetic field and without magnetic field. The surface observation shows that the surface magnetic particles of the sample are increased with the increase of volume fraction, and the surface roughness of the samples of each component is reduced, with the magnetic field, the ferromagnetic particles of MREs with the volume fraction of 5% is reduced most up to about 20%. The friction experiment results show that the friction coefficient is decreased with the increase of volume ratio and under the application of magnetic field, the 30% of MREs' friction coefficient is reduced by approximately 38% compared to the 5%. The ferromagnetic particle content on the surface of the MRE is a major factor affecting the friction characteristics.
