Here, the lubrication problem in a slider bearing is investigated using the FENE-P constitutive equation. The nonlinear Reynolds equation is solved semi-analytically. The influence of the Deborah number and extensibility parameter on the distribution of pressure, velocity profile, shear stress, first normal stress difference, load-carrying capacity, and friction factor are analyzed. The results indicate that increasing Deborah number causes pressure distribution, load-carrying capacity, shear stress, and the magnitude of the velocity (at the entrance) to decrease while also causing normal stress difference, friction factor, and the magnitude of the velocity (at the exit) to increase. Also, as the extensibility parameter increases, pressure distribution, load-carrying capacity, shear stress, and velocity profile at the inlet become greater. However, the friction factor and velocity in the outlet reduce. It is also observed that when extensibility approaches infinity, the load-carrying capacity and friction factor approach a specific constant value which is independent of Deborah number.

在这里，使用 FENE-P 本构方程研究了滑动轴承中的润滑问题。非线性雷诺方程以半解析方式求解。分析了Deborah数和延展性参数对压力分布、速度剖面、剪应力、第一法向应力差、承载能力和摩擦系数的影响。结果表明，增加 Deborah 数会导致压力分布、承载能力、剪切应力和速度（在入口处）的大小减小，同时也会导致法向应力差、摩擦系数和速度的大小（在入口处）减小。出口）增加。此外，随着延展性参数的增加，入口处的压力分布、承载能力、剪切应力和速度分布变得更大。然而，出口的摩擦系数和速度降低。还观察到，当延伸性接近无穷大时，承载能力和摩擦系数接近一个特定的常数值，该常数值与 Deborah 数无关。
