A New Numerical Model of Contact Pressure in Vane Seals

The sealing contact pressure is critical in determining the film thickness of elastohydrodynamic lubrication, the friction force on the seal, and the sealing reliability of vane seals, so it is one of the most important parameters in evaluating the sealing performance of vane seals. A numerical model of contact pressure for vane seal is built based on elastic mechanic method, which is used to solve these problems of contact stress, strain and displacement on sealing surface. The interaction between adjacent units during deforming is fully considered for this model, which results in that this model is closer to the actual situation.
