    Abstract
  • O-ring seal structure is widely used in the weapon systems of air and ship, and its sealing performance directly affect the operational mission of the weapon systems. The existing design methods of O-ring seal do not sufficiently consider the effects of manufacturing tolerance, medium pressure fluctuation, etc., on the reliability of O-ring sealing performance, and cannot give quantitative value of reliability index. In this paper, the stress-strength interference theory is employed to establish a limit state function of O-ring seal structure considering the influencing factors mentioned above, and corresponding calculation method of reliability is proposed. Then, reliability of the O-ring seal structure for an underwater vehicle is calculated by the software FREET. This study may provide a reference for design of O-ring seal structure.
