研究了磁流变弹性体（MRE）在不同振动条件下的摩擦磨损性能。实验研究了在外加磁场作用下，在不同频率和幅值的正常振动条件下，MRE摩擦系数和磨损的变化规律。为此，设计并制作了往复摩擦试验机和试样。结果表明，在所有测试条件下，摩擦系数随磁场的增大而减小。随着振动的增加和频率的增加，摩擦系数增大。摩擦系数随振幅的增大而减小。在有磁场和无磁场的情况下，不同振动频率和振幅下的磨损也有显著变化。(C) 2016 Elsevier Ltd.版权所有。
In this study, the friction and wear properties of magnetorheological elastomer (MRE) were examined under various vibration conditions. The variation of the friction coefficient and wear of the MRE was investigated experimentally with an applied magnetic field and different frequencies and amplitudes of normal vibration. To accomplish this, a reciprocating friction tester and test samples were designed and fabricated. The results show that the friction coefficient decreased with the magnetic field in all test conditions. The friction coefficient increased when vibration was applied and the frequencies were increased. The friction coefficient decreased as the amplitudes increased. The wear also significantly changes under different vibration frequencies and amplitudes with and without a magnetic field. (C) 2016 Elsevier Ltd. All rights reserved.
