- Abstract:
- This paper has researched the mechanical property of the rubber O-ring which is the major part of the sealing structure,and obtained the structural respond of the rubber sealing ring of the SRM under uncertain factors by the integral stochastic finite element method 0SFEM).The paper has accomplished the mechanical property simulation and the reliability analysis of the SRM sealing structure respevtively under natural aging and working conditions.
