In order to satisfy the demands of virtual interchangeability verification of key aircraft components, the high-precision and rapid reverse modeling and reconstruction technology for aircraft assembly components is applied to accurately mirror the geometric information of datum parts and interchangeable parts, and to construct a digital twin model of target components. In addition, by developing and applying the visual interchangeability simulation analysis system of human-computer interaction, the application of model-based virtual interchangeability coordination method has been realized during aircraft development process, which substitutes the traditional inspection method for interchangeability and coordination with physical items, and reduces the inspection cycle of aircraft component interchangeability and improves the development efficiency of aircraft products.

By making deep analysis on the big data information of historical product, the technology of structured data classification based on deep learning can form knowledge for part capability type recognition and judgment, build a model of capability type recognition on the basis of deep neural network, and also develop a software system of capability type automatic recognition ,for assisting the recognition of part capability type. For part newly imported into the system, combined with its attached attribute information, this technology can automatically identify and recommend the capacity type, and forms a set of knowledge-based method for the recognition and judgment of part capacity type.
