对流体动力润滑基本方程的再检讨

This paper investigates and discusses the basic equations of hydrodynamic lubrication. It strictly proves that the right side of the Reynolds equations being less than zero is sufficient and essential to create hydrodynamic lubrication between two lubrication surfaces. It points out that the formation of steady hydrodynamic lubrication does not require the co-existence of relative slip velocity and converging slots. While explicating the concepts of squeezing term and the wedging term in the Reynolds equations, a modified Reynolds equation with better universality is proposed with regarding to the sliding surface lubrication problem.
