Abstract
Notice of Retraction
After careful and considered review of the content of this paper by a duly constituted expert committee, this paper has been found to be in violation of IEEE´s Publication Principles.
We hereby retract the content of this paper. Reasonable effort should be made to remove all past references to this paper.
The presenting author of this paper has the option to appeal this decision by contacting TPII@ieee.org.
Sealing reliability plays a very important role in the aviation field. This paper develops a new sealing reliability analysis method which can be applicable to most of the static seals. For the long-term using rubber seals, it will emerge stress relaxation which may lead to sealing failure. Therefore, a stress relaxation factor is need to be defined, which will analyze the sealing reliability considering the stress relaxation. Then, taking the o-ring as an example, the static sealing reliability of the o-ring in operating conditions is calculated. Also the influence of design parameters on the sealing reliability is analyzed. Finally some conclusions are given: (1) When the design parameters are deterministic, the stress relaxation factor, variance and correlation coefficient of the random variables will make a big influence on the sealing reliability; (2) When the design parameters is not deterministic, the compression ratio and media pressure also have a big influence on the sealing reliability.
