Technical application of aircraft canopy assembly according to research on structural thermal deformation
Since the canopy suffers obvious changes in its status as well as low efficiency in assembly and debugging efficien-cy of when the aircraft is going through environmental changes,in this article efforts are made to explore the common technologies for canopy assembly and debugging,according to the principle of structural thermal deformation.The coupling calculation model is set up for the canopy's structural thermal deformation;the method of applying heating loads to the canopy based on the envi-ronmental temperature is proposed.The finite-element method is used to work out the law of structural thermal deformation with changes in the environmental temperature,and the results are verified through a series of experiment.The main factors influen-cing the assembly size of the aircraft canopy are identified.According to the law of the aircraft canopy's structural thermal de-formation and the assembly optimization method of the large-sized moving parts,the assembly process is optimized and the specific calculation program is developed.Finally,desirable results in actual projects are yielded through verification.
