This paper discusses the combined effect of Non-Newtonian rheology of lubricants and slip boundary condition on the static performance characteristics of finite hydrodynamic journal bearings. A modified JFO model with an adiabatic energy equation has been used for calculating the variation of performance parameters. It has been observed that shear-thinning lubricant with slip effect on partial circumferential region shows a significant percentage of improvement in load-carrying capacity and coefficient of friction. Further, For eccentricity ratio of less than 0.2, these lubricants give maximum tribological performance as compared to Newtonian lubricants under conventional boundary condition.

本文讨论了润滑剂的非牛顿流变学和滑动边界条件对有限流体动力滑动轴承静态性能特性的综合影响。具有绝热能量方程的修正 JFO 模型已用于计算性能参数的变化。已经观察到在部分圆周区域具有滑动效应的剪切稀化润滑剂在承载能力和摩擦系数方面显示出显着百分比的改进。此外，对于小于 0.2 的偏心比，与传统边界条件下的牛顿润滑剂相比，这些润滑剂具有最大的摩擦学性能。
