摘要

采用迭代法对微极流体(非牛顿流体)润滑短层多孔静压滑动轴承的特性进行了理论分析。为了研究静压滑动轴承的特性，推导了微极流体情况下的修正雷诺方程，并对其进行了数值求解。通过与先前发表的牛顿和非牛顿润滑油的结果进行比较，以设计图的形式验证了本工作的结果。所研究的轴承的静刚度和承载能力分别比常规静压轴承高80%和75%。多孔静压滑动轴承具有较好的经济性，因为它需要40%的低流量和较低的泵功率，并且与其他静压滑动轴承相比，它产生的热量减少了50%。

Theoretical investigation of porous hydrostatic journal bearing under micropolar fluid lubrication

The features of micropolar fluid (a non-Newtonian fluid)–lubricated short single-layered porous hydrostatic journal bearing are analyzed theoretically by an iterative method. To investigate hydrostatic journal bearing characteristics, a modified Reynolds equation in the case of micropolar fluid is derived and solved numerically. The obtained results in this work are validated by comparing the same with previously published results with Newtonian and non-Newtonian lubricants in the form of design charts. The static stiffness and load-carrying capacity of the investigated bearing are 80% and 75% higher than conventional hydrostatic bearings. The porous hydrostatic journal bearing exhibits more economical performance as it requires 40% low flow rate and low pump power, and it generates 50% less heat in contrast with other hydrostatic bearings.
