- The stress-strain state of a sealing element in the form of a hollow cylinder is defined with regard to viscous-elastic properties of its material. Based on linear laws of heredity, an analytical formula allowing one to determine the axial load necessary for tightness of the surface of the sealing element and the cylinder wall depending on its physic-mechanical properties and geometrical dimensions is found. Influence of viscous-elastic properties of the material of the sealing element on its sealing ability is realized based on the hypothesis of elastic analogy. The results of numerical calculations are represented in the form of graphs of the external force necessary for achieving sightless. It is shown that viscous-elastic properties of the sealer material greatly influence its sealing ability. Because of heredity of the sealer material, values of the external forces drop in some cases by about five times.
