FEA of a Double-Point Contact Elastomeric Gasket Considering Corrosion of Counterparts and Tilting during Assembly

Abstract:

The novel geometry of a gasket’s cross-section to optimize the sealing performance was proposed in spite of corrosion of its counterparts or tilted assembly. EPDM was applied for the rubber material and the sealing performance including stress, strain and contact pressure was estimated by finite element analysis (FEA) in both cased of normal and tilted assemblies. If the gaskets were to be normally assembled in the grooves, both gaskets (single-point contact and double-point contact) could be utilized for sealing systems. Even at the tilted assembly, the double-point contact gasket showed two discrete contact pressure areas; thus it could maintain its sealing performance over time at various operating conditions, compared to the single-point gasket.
