【 摘 要 】
Since cabins must be continuously pressurized during flights, the sealing of cabin doors is a dynamic process. In the whole working process contact states of seals are very complicated, and they change over time. So it is very important to find out separate positions and contact positions accurately to study the leaking of doors. In this paper the surface-based pressure penetration capability of ABAQUS is used to simulate pressure penetration between contacting surfaces of a P-shape seal component subjected to a vertical load and an internal pressure. Information such as deformed configuration and contact stress contours, comparison of fluid pressure and contact pressure is obtained in the analyses. Results show that P-shape seal has a good seal performance. And the analysis of cabin door seals is an important application where pressure penetration effects are important.
