Theoretical study of non-Newtonian effects of second-order fluids on the performance characteristics of inclined slider bearings is presented. An approximate method is used for the solution of the highly nonlinear momentum equations for the second-order fluids. The closed form expressions for the fluid film pressure, load carrying capacity, frictional force, coefficient of friction, and centre of pressure are obtained. The non-Newtonian second order fluid model increases the film pressure, load carrying capacity, and frictional force whereas the center of pressure slightly shifts towards exit region. Further, the frictional coefficient decreases with an increase in the bearing velocity as expected for an ideal fluid.
本文给出了二阶流体非牛顿效应在倾斜滑块轴承性能特性方面的理论研究。采用一种近似方法求解二阶流体的高度非线性动量方程。得到了流体膜压力、承载能力、摩擦力、摩擦系数和压力中心的闭式表达式。非牛顿二阶流体模型增加了膜压力、承载能力和摩擦力,而压力中心略微向出口区域移动。此外,正如理想流体所预期的那样,摩擦系数随着轴承速度的增加而降低。
