Abstract

Abstract: According to the characteristics of the material heterogeneity of the composite sealing ring, the microscopic sliding contact is investigated based on the movable cellular automata. The microscopic dynamic responses of sealing surfaces are visualized when loads are applied according to the actual working conditions. The frictional behaviors of the polyimide (PI) and the polytetrafluoroethylene (PTFE) composite sealing rings are analyzed, and the changing processes of friction coefficients are obtained within the simulation time. The results show that the formation and evolution processes of the mechanically mixed layers of PI and PTFE sealing rings are basically the same. The friction coefficient of PI sealing ring is greater than that of PTFE one. The properties and morphology of filler materials determine the microscopic friction behaviors. The friction test is conducted for PI and PTFE sealing rings. The coefficients of friction in the simulations and tests are calculated and compared. The results indicate the effectiveness of microscopic frictional simulations in the mixed lubrication based on the movable cellular automata.
