中文摘要：

为了分析传动壁面形貌对磁流变液滑移特性的影响规律,建立磁流变传动性能实验台,分析了传动壁面沟槽形状、沟槽密度、沟槽深度、纹理类型等对滑移强度的影响规律,研究发现,滑移强度与传动壁面表面形貌有关,壁面沟槽形状对滑移强度影响并不明显,三角形截面形状略优于矩形;增加沟槽密度可提升磁流变液的传动能力,沟槽深度在0～0.5mm范围内存在最优值;同心圆、光滑、凹坑及径向辐射条纹4种壁面形貌中,滑移强度由大到小依次是：径向辐射条纹、凹坑、光滑、同心圆,改变壁面形貌可使滑移强度提高10%。

To obtain the wall slip effect of magnetorheological fluids,the magnetorheological transmission properties test-bed was established,the influence rules of groove shapes,groove densities,groove depths,texture types of wall were researched respectively,the results indicate that wall slip intensity has relationship with surface textures of disk,of which the influence of groove shape of disk was indistinctive,and the triangular section shape was slightly better than rectangular;the increase of groove density can improve the capacity of torque transmitted,and the groove depth has a optimized value range from 0-0.5mm,the wall texture slip intensity range from small to big is radialized wall,potholed wall,smooth wall and annular wall,the appearance of wall texture can improve the wall slip intensity about 10%.
