The mechanism of magnetorheological elastomers (MREs) friction regulation under the magnetic field is of great significance to improve the adaptability of smart devices to changing contact conditions. Therefore, an integrated evolution model of the microstructure is proposed to investigate the adjustment of the magneto-mechanical coupling properties of MREs on the interface friction. The model clarifies that the ferromagnetic particles volume fraction, matrix modulus, and magnetic field intensity respectively change the initial arrangement and evolution process of particles to achieve the adjustment of stiffness and surface morphology, and finally achieve friction regulation. As the volume fraction increases, the reduction of friction force shows a trend of first increasing and then decreasing, and the reduction reaches the maximum when the volume fraction is about 10%.

磁场下的磁流变弹性体（MRE）摩擦调节机制对于提高智能设备对变化的接触条件的适应性具有重要意义。因此，提出了一种微观结构的综合演化模型，以研究MRE在界面摩擦力上的磁-机械耦合特性的调整。该模型表明，铁磁颗粒的体积分数，基体模量和磁场强度分别改变了颗粒的初始排列和演化过程，从而实现了对刚度和表面形态的调节，最终实现了摩擦调节。随着体积分数的增加，摩擦力的减小呈现出先增大后减小的趋势，
