Abstract
The invention is named as an encoding method of airplane parts and relates to the technical field of encoding systems for parts in a general-purpose airplane development process. In a traditional encoding method, a navigation mark stipulation method is adopted, configuration changes can not be embodied in marks, and encoding of the parts is determined and planned by people, so that double number occurs easily, the advantages of computer management can not be brought into play, and application of advanced configuration management thoughts can not be met. According to the encoding method provided by the invention, an expression mode based on fifteen capital English letters and Arabic numbers is adopted for encoding the parts and configuration items, and a tribit tail number and a single-bit version number are introduced for embodying the configuration changes and version changes, so that effects such as efficient encoding and information expression are realized, the mark traceability in a configuration change process is also realized, a double number phenomenon is avoided, automatic encoding can be supported, the design quality is improved, and the encoding method can be widely applied to model number numbering of various aviation products and technical management of enterprises.
Description
Technical field
Patent of the present invention relates to coding of parts and components system technical field in general-purpose aircraft development process.
Background technology
Patent of the present invention is mainly used in parts in large-scale amphibious aircraft digitizing development, production run and sets up coding scheme.In most domestic design process, coding method is that the method specifying by navigation mark is carried out; this standard is the management method based on drawing based on traditional; for the civil aircraft of complex configuration; often there will be the inadequate phenomenon of numbering resource; be not suitable with modern digitalization development, can not meet the needs of modern configuration management.
The development of large-scale amphibious aircraft is to adopt digitizing means, and data generate the method adopting based on model definition (MBD is labeled in three-dimensional model and completes), no longer draw two-dimentional pattern.Therefore, need to formulate reasonably, meet the coding scheme of modern configuration management and control needs.
Summary of the invention
Patent of the present invention adopts the coding scheme in the built-in knowledge base that is based on of product data data management system, and configuration item (CI), spare part, assembly parts are carried out to class indication.Manage level and the membership between CI by data management system, the hierarchical relationship of part or parts and membership in same CI, the relation of CI and file, file and change, has solved reviewed to the problem of change.
All kinds of spare part codings are the important rings in the activity of configuration mark, are also the marks that embodies digitized degree height.Tradition spare part coding is mainly determined by people and plans, not only can not bring into play the advantage of computer management, nor can meet the utilization of advanced configuration management thought.For the shortcoming of traditional coding scheme, in the development process of large-scale amphibious aircraft, we adopt the coding scheme based on knowledge base.This coding scheme can be expressed the change of product life cycle management, attribute of component and review and the much information such as change of configuration,
Coding scheme based on knowledge base, except solving the problems such as high efficient coding and information representation, has also solved and in configuration change procedure, has identified trackability problem.By configuration control, to change with regard to spare part, change mark is divided into: rise version and change two kinds of modes with dash number.For reaching the object of configuration trackability and distinct configuration, polarize the using priciple with two kinds of modes of specification.Wherein dash number changes will affect the configuration of product, and realizes this change by producing variable configuration item (VCI), and effectively rule of linear latest edition is observed in the variation of version.
Patent of the present invention adopts the expression way of capitalization English letter and arabic numeral to encode to spare part and CI, is represented by 15 alphabetical erect-positions of ABCDEFGHIJKLMN0, and the represented implication of each letter is as table 1.
Patent of the present invention can effectively solve in high efficient coding in configuration management process, information representation and configuration change procedure and identify trackability problem.Avoid occurring double sign phenomenon, can support automatic coding, improve designing quality.Patent of the present invention can be widely used in all kinds of aeronautical product model number and enterprise technology management.
Brief description of the drawings
Below in conjunction with accompanying drawing, patent of the present invention is further illustrated.
Fig. 1 is large-scale amphibious aircraft dash number structure.
In figure, 1. models are simplified mark, 2.ATA2200 chapter number, 3.ATA2200 section number, 4.ATA2200 segment number, 5. part classification code name, 6. serial number, 7. tail number, 8. version.
Embodiment
1) formulate coding rule
Formulate coding rule, comprise configuration item, self-made components, finished product, material and standard component coding rule, include the coding (international standard ATA2200) of supporting that product ensures in, prescribed coding figure place is carried out field information and is given, use computing machine sequential encoding, carry out version identifier etc.
2) carry out different identification for different spare parts
Table 2 spare part classification code name
3) increase change of configuration rule encoding
Tail number is set, and tail number is made up of three bit digital, as the coding of controlling change of configuration, embodies attribute of component and change and reviews variation, in table 3.
Table 3 tail number
