Web-Enabled Database for Gasket Parameters

Abstract

The available technique of a Web-enabled material database was adapted to a new Gasket Data Bank (Gasket-DB) in the frame of an European research project PERL (Pressure Equipment, Reduction of Leak rate: gasket parameters measurements). Main content are gasket characteristics determined on all gasket types defined in the new European gasket standard series EN 1514, part 1 to 7: • actual gasket parameters in ENV 1591-2 (public access), • proposed gasket parameters to define more reliable values (restricted access), • certified manufacturers gasket data (restricted access), • gasket parameter ranges (public access). Data retrieval is providing intelligent user guidance. Data entry is carried out by Joint Research Centre (JRC) Petten, NL, by means of standardized format (Excel file with different sheets, reflecting the table structure of the database). The prototype database and the user interface can easily be extended and customized to the needs and requirements of the engineering gasket society, e.g. link to customer documentation, databases, services like design calculation tools.

Non-linearity of the contact layer between elements joined in a multi-bolted connection and the preload of the bolts

“…Źródłem tej nieliniowości są m.in. uszczelki lub podkładki często stosowane jako elementy pośrednie w tego typu połączeniach [14,15].…”

“…Multi-bolted connections (composed of many objects remaining in contact) are treated as non-linear systems in the calculations. The source of this non-linearity are, for example, gaskets or washers often used as additional intermediate elements in this type of connections [14,15].…”
