In order to reveal the influence of rotating speed on the stability of torque transmission by magnetorheological fluid, magnetic force, centrifugal force, gravity, stokes resistance and buoyancy of particles are calculated and analyzed. Besides, the rule of particles distribution is simulated by the Fluent software. On this basis, experiments are carried out based on magnetorheological transmission device. The results indicate that the centrifugal force due to rotating speed has greater effect on particles concentration as there is no magnetic field, and particle concentration mainly appears at the outer diameter of disk, but its effects are concentrated only in a smaller area, which will enhance the local working magnetic field. When the particles are subjected to a strong magnetic field, the magnetic force between the particles is much greater than the centrifugal force; thus, the influence of rotating speed can be ignored. The relationship between transmittable torque and rotating speed is not linear due to the hydraulic torque at the speed of 0–80 r/min.

为了揭示转速对磁流变液传递扭矩稳定性的影响，计算分析了磁力，离心力，重力，抗斯托克斯性和浮力。此外，通过Fluent软件模拟了颗粒分布的规律。在此基础上，基于磁流变传动装置进行了实验。结果表明，由于没有磁场，转速引起的离心力对颗粒浓度的影响更大，颗粒浓度主要出现在圆盘的外径，但其作用仅集中在较小的区域，这将增强局部工作磁场。当粒子受到强磁场作用时 粒子之间的磁力远大于离心力。因此，可以忽略转速的影响。由于在0–80 r / min的速度下的液压扭矩，可传递的扭矩与转速之间的关系不是线性的。
