Abstract:
Axisymmetric static Finite Element (FE) models were used to study sealing geometric changes on valve stem seals (VSSs). FE analysis is used to characterise the deformation of the rubber seal, and the contact pressure distribution. The deformations were analysed using animation techniques. The research gives a first order approximation, revealing magnitude and direction of seal lip to valve stem contact. Finally, a hypothesis on the sealing and lubricating mechanism is proposed.
