Abstract: By the fluid dynamics theory analysis of the sealing interface, the importance of sealing contact pressure research for sealing performance is discussed. By experiments and data analysis for nitrile rubber buna and polyurethane, Mooney–Rivlin model parameters of two materials are obtained. By the finite element analysis of bud-shaped composite sealing ring under different pressures and secondary analysis, sealing contact pressure distribution curve of finite element analysis has been obtained. Sealing experimental apparatus is designed and as...
