ABSTRACT

Security and reliability are the main focus of annular metal seal assembly. It is concluded that the factors influence sealing performance of annular metal seal assembly most in view of working conditions of annular metal seal assembly. Taking major influencing factors with response surface method (RSM) analysis, and determining coefficient of regression analysis with finite element method (ANSYS) experiment. Second-order corresponding model is established and the best corresponding interval is concluded. Getting the reasonable values of bulge radius r and loading F on the premise of guarantee the y value and providing theoretical guidance for field operation combined with metal sealing seal principles and experimental research.
