摘　　要：为了保证磁流变传动装置的动力传递效果,采用实验方法,分析了不同壁面材料、表面粗糙度大小、壁面形貌、滑差转速及工作间隙对磁流变传力性能的影响规律。研究表明壁面材料对磁流变液动力传递效果影响较为明显,材料磁导率越低,传递转矩越小,容易发生壁面滑移现象;壁面形貌亦为影响传力效果的主要因素,凹凸同心圆表面减弱了磁流变液的传力性能;高滑差转速时,磁流变液颗粒成链较为复杂,其传递转矩随滑差转速的增加而逐渐降低,而工作间距对其传力性能影响不大。To ensure the torque transmission properties of magnetorheological transmission device,the experimental method is used to analyze the effect of material,rough,surface morphology of disk,slip speed and working gap on the torque transmission properties.The results indicate that material of wall has a significant influence on the properties,the lower the permeability of material,the smaller the torque transmits,and the wall effect will appear;the surface morphology of disk has also an important influence on the transmission properties,the concave convex concentric circles surface reduces the torque;when the slip speed is higher,the process of particles chains formed is complex and the torque will be lower,the working distance has little effect on the transmission properties.
