The article deals with the stress-strain analysis and investigations of operating properties of metal high-pressure gaskets. The simplified analytical approach is applied in the examinations of wave-ring gasket and lens-ring gasket. A cylindrical shell of constant mean thickness is introduced to simulate the gaskets. It is assumed that the shell is simply supported at the inner surfaces of the gasket seats. The influence of certain geometric, material and assembly parameters on the strength and leak-tightness of the closures is analytically investigated. Certain selected parameters of the closure are examined versus applied operating pressure for the assumed materials of the gasketed members and fixed several another data of the gaskets. The analysis is carried out in dimensionless variables in order to generalize the results. The region of admissible solutions for the gaskets parameters such as dimensions, applied assembly requirements and operating pressure is determined. The static tensile tests were carried out to determine the real mechanical properties of materials applied for the gaskets and the seats. The analytical solutions are verified by FEM calculations, which take into account the hardening of the material, friction at the surfaces and contact effects. Theoretical considerations are illustrated by numerical examples and compared with the experimental results obtained under assembly conditions with no operating pressure applied to the closures. Some conclusions may be recommended in design procedures of the high-pressure closures with metal gaskets.
