Abstract

The stress relaxation of the metallic seal is a general problem during its long-term service, which is harmful for the sealing performance. For the metallic seal, the sealing mechanism and the problem of the stress relaxation are analyzed, and the research methods applied to study the problem of stress relaxation of the metallic sealing material are proposed in this paper. Further, the dynamic equation of the metallic seal is developed, and the data processing method and the solving method of the dynamic equation are also put forward, which are based on the stress relaxation experiment. Based on the proposed mathematics methods and the experimental data of the stress relaxation, the analysis about the characteristics of stress relaxation of the two metallic sealing materials are carried out, which include of the aluminum and the silver that are common materials used by the metallic seal. To the specific test conditions, the dynamic equations of stress relaxation are respectively presented, which lay the foundation for judging the sealing performance of the metallic seal during its long-time service.
