In this paper, the field equation of micropolar fluid with general lubrication theory assumptions is simplified into two systems of coupled ordinary differential equation. 本文从微极流体场方程出发,在润滑层的通常假设下,把它化简为两个独立的常微分方程组,并求得速度、微转动角速度的解析表达式。
Numerical results indicate that ( 1) In general, herringbone-grooved journal bearings with micropolar fluid of high coupling numbers have higher load capacity and slightly larger friction resistance than that with Newtonian lubricants. 计算结果显示:(1)高耦合数的微极性流体螺旋槽径向轴承比一般牛顿流体为润滑剂的轴承具有较高的承载力,摩擦阻力略有增加。
