摘要（英）：

The invention belongs to the technical field of metal sealing detection, particularly relates to a metal sealing stress relaxation property analysis and calculation method, aims at providing the metal sealing stress relaxation property analysis and calculation method, and is used for representing the metal sealing stress relaxation property. The concrete expression of a stress relaxation kinetic equation can be determined on the basis of a stress relaxation test so as to analyze and evaluate the sealing performance of metal sealing in the long-term use process. The method is characterized by comprising the steps of data acquisition, data processing and judging whether the sealing performance meets the requirements. The metal sealing stress relaxation kinetic equation can reasonably and comprehensive represent the metal sealing stress relaxation property; and the regression processing method of the metal sealing stress relaxation test data can effectively process the metal sealing stress relaxation test data and determine the unknown parameters of the stress relaxation kinetic equation so as to obtain the stress relaxation kinetic equation and a stress relaxation curve under the metal sealing test state.
