Integrated Analysis System for Dynamic Sealing Performance of Civil Aircraft Boarding Door

This paper introduces an integrated analysis system for the dynamic sealing performance of civil aircraft boarding doors. The analysis system mainly carries out virtual verification for the sealing performance of civil aircraft doors in various service environments, including the simulation module of fluid pressure temperature on the surface of aircraft doors. There are three subsystems: hatch fluid-structure coupling interpolation module and hatch dynamic sealing performance finite element simulation module. The system is used to simulate the sealing performance of civil aircraft boarding doors in complex dynamic environments such as under high and low temperatures and high and low pressures. The system can improve the evaluation mechanism of aircraft hatch dynamic sealing performance, and help to build a virtual simulation analysis and test verification system of hatch performance under the interaction of multiple environmental factors, so as to help overcome the bottleneck in the development of civil aircraft in China.
