Abstract

Abstract

To clarify the mechanism of fluid infiltration in the rubber-glass contact interface, an experimental setup of in situ observation instrument was established. Then, the fluid infiltration process in the rubber-glass contact interface was measured. The influences of the interfacial contact characteristics and the solid-liquid interface wettability on the fluid infiltration area ratio, the path and the distribution pattern were analyzed with a MATLAB program and an image processing software. Analysis results show that, all the fluid infiltration area ratio, the path and the distribution pattern in the contact interface are influenced by the capillary force and the real contact area ratio. First, the actual contact area ratio nonlinearly increases in the form of power functions with the interfacial contact pressure. Second, the fluid infiltration path in the contact interface tends to form where the actual contact area ratio is high. The main driving mechanism of the liquid infiltration path and the velocity in the contact interface is the equilibrium relation between the capillary force and the viscous resistance. Moreover, the solid-liquid interfacial wettability is one of the evaluation indexes for the fluid infiltration area ratio in the contact interface. Reasonable regulation and control of the wettability of the solid-liquid interface can improve the infiltration effect of fluid. The research work provides an innovative approach and obtains an essential understanding of the effects of fluid infiltration on friction, lubrication and seal in the rubber contact interface.
