Radial Lip Seal Simulation Using ANSYS Non-standard Procedures
Elastomer and PTFE lip seals are widely used in industries such as engines and other mechanical devices. The amplitude and distribution of seal contact pressure are major factors affecting seal performance and wear. Contact surface profile changes continuously due to material worn off. Worn off material has to be removed from FE models continuously to obtain a realistic solution and uncover the mechanism of seal wear. Non standard ANSYS rezoning procedure and APDL macros have been developed to investigate PTFE lip seal wear and improve product reliability in this paper.
