| Abstract: | In space engineering, multi-level series seal structures are always adopted to assure safety and reliability.The topology and element restraints in gas circuit were summarized. The mathematical model building method of series seal systemwas presented based on it. The whole process and balancing process model of series seal system was built. Every state variable analytic expression of series seal system in leakage process was deduced. Numerical calculation and simulation algorithm were presented. The simulation software for multi-level series seal system was introduced. The simulation examples were given. Finally, the conclusion and its application are generalized. |
