研究同心圆筒型电流变离合器内流动屈服面的瞬态响应规律。结果表明 :在突加电场情况下 ,电流变液屈服应力公式中的参数 β对流动屈服面的动态特性规律有重要影响。初始时刻 ,屈服面在筒壁生成 ,在向间隙内移动的过程中 ;若 β >2 .0 ,屈服面总是先产生于内筒外壁 ;若 β <2 .0 ,屈服面总是先产生于外筒内壁
The transient response of the flow surface in concentric cylindrical electrorheological clutch was studied. The results show that the parameter β in the yield stress of ER fluid has an important influence on the dynamic behavior of the flow surface under the sudden electric field increase. At the initial moment, the yield surface is generated in the cylinder wall, and during the movement to the gap, if β> 2.0, the yield surface is always generated first on the outer wall of the cylinder; if β <2.0, the yield surface is always generated first In the outer cylinder wall
