Numerical Simulation Method of Leakage for Lip Seal

Abstract:

Lip seal, widely used in industries, is usually applied to seal pressure chamber. Leakage of lip seal has always been a primary problem. In the present study, hydrodynamic property of lubricating film and elastic deformation of sealing lip are analyzed numerically by coupling Reynolds equation and elastic deformation equation. A numerical model for calculating leakage is proposed, results of the analysis will be of help to interference design and structure optimization for auto water pump bearing’s seal.
