Abstract
An experimental and theoretical research was conducted in this work focused on seal behavior. An innovative mixed lubrication model considering the elastohydrodynamic (EHD) theory which introduces a deformation theory was employed. This paper presents a computational procedure for resulting a coupled solution of the fluid and the seal. The model gains insight into the effects of seal pressure, rod velocity and the compression ratio on the sealing characteristics in terms of the contact pressure, fluid pressure distribution as well as fluid transport in the sealing zone. The proposed approach accurately predicts the friction force corresponding to the experimental data and provides a theoretical basis for EHL modeling that captures the sealing characteristics.
