Deformation Study on Simulation and Airworthiness Validation of Cabin Door Under High and Low Temperature and Horizontal Gust

The airworthiness regulations and terms related to the deformation of the cabin door and its seals are analyzed,and the main airworthiness requirements related to the deformation are determined.Based on the construction of the deformation models of the cabin door and its seals by SolidWorks,the deformation analysis of the cabin door and its seal under the conditions of extremely high and low temperature,horizontal blast and their combination are carried out,then airworthiness compliance certification of the cabin door and its seals based on the simulation is presented.By the principle of virtual force,the deformation analysis of the door block is carried out and compared with the simulation.The results show that the deformation simulation method and the airworthiness compliance certification process of the cabin door and its seal discussed are reasonable and feasible.
