The factors influencing sealing performance are considered, such as initial compressibility, sealing materials.
The seal material and compression ratio are both great influence on the sealing performance , which should be based on working conditions to select the appropriate sealing materials.
In this paper, the same sealing structure is established for three different materials seal to simulate their own the sealing performance.
The three materials seals worked in the maximum contact stress curve is shown in Fig.3, and the maximum shear stress curve is shown in Fig.4.
The seal material and compression ratio are both great influence on the sealing performance , which should be based on working conditions to select the appropriate sealing materials.

For the domestic high repair cost and longtime of air material purchase cycle, the new generation of avionics systems are sent to abroad for repair.
This greatly reduces the use of air material turnover and increased inventory.
American, Japan, Israel and other countries have invested a lot of manpower, material and financial resources.
