Description

Airplane assembly and integration test platform and test method TECHNICAL FIELD

[0001] The present application relates to the field of system assembly / test, in particular to an airplane assembly and integration test platform and test method. BACKGROUND

[0002] The assembly and integration test process of an airplane is a complex system engineering process, and is also a process of changing from spatial constraints in the installation stage to principle constraints in the test stage in airplane manufacturing. As one of the last and most important links in airplane manufacturing process, the assembly and integration test involves numerous professional technologies and extremely complex process flow.

[0003] At present, the assembly and integration test of an airplane has improved in digitalization with the introduction of digital assembly and test equipment, but still faces the following problems: full-element data classification and standardized definition have not been realized. There are many data sources for the assembly and integration test of an airplane in each airplane manufacturing factory, including multiple types of design documents, numerical models, process documents, process models, and data generated by tests, etc. The data sources exist in various forms, including electronic documents, various database types, standard markup language types, and paper records, etc. Since most systems are independently designed and developed, a large number of data islands are formed. With the continuous increase of information, it is difficult to effectively utilize the data information, and the demand of assembly process control cannot be met. Assembly and test do not form effective collaboration, and assembly work and test work lack information interaction. The assembly and integration test process mainly by hand operation has no efficient guidance means. Since the current system integration and assembly of an airplane still mainly relies on manual operation, in the on-site work process, it is often difficult to find, compare, and understand effective information. The existing operation guidance for airplane assembly and test needs to look up paper documents while checking electronic manuals, and the operator works discontinuously. The consistency of the physical state of the airplane product and equipment with the three-dimensional model is poor. According to the traditional assembly method, it is difficult to effectively guide the actual assembly personnel to complete the assembly work, resulting in low assembly process efficiency and high assembly rework rate.

[0004] In view of the above problems existing in the assembly and integration test, it is urgent to form an airplane precise assembly and interactive test platform based on basic data, realize comprehensive collection, analysis, and storage of assembly basic data, use digital means based on assembly and integration test basic data, and make real-time decision of process control information, so that different processes and different flows can work collaboratively, and the operator can be guided to complete assembly and test operation efficiently and accurately through augmented reality and other means, and the assembly efficiency and quality can be significantly improved.
