Drawings
FIG. 1 is a block diagram of a hierarchical management framework for an aircraft data organization structure provided herein;
detailed description of the invention
Example one
According to the method, the airplane data structure is subjected to modularized layering by combining a traditional airplane work decomposition structure model according to a modularized thought, and the airplane data structure comprises a top-layer structure layer, a state control layer and a part design layer, as shown in figure 1. The aircraft is divided into appropriate modules from the design and manufacturing point of view for management and design production. The modules herein are managed objects that contain a partitioning of assembly relationships or a process recipe and other attributes. The method has the advantages that the complex airplane system can be decomposed into a plurality of independent and related units and used as the object of configuration management, namely, the management work is implemented under the flattened data organization structure, and the obvious advantages are embodied in the following aspects: the system reliability is improved, the design period is shortened, the integration is good, the cost is low, and the response and the maintenance are convenient.
It should be noted that the data organization structure is a general technique for organizing aircraft data, and is a hierarchical view of the relationship between an aircraft and components. The data structure defines a composition of the aircraft and is associated with aircraft configuration information.
The method comprises the following steps: and constructing a top layer structure layer of the airplane data organization structure according to airplane models, sections and covered systems/subsystems.
Specifically, a top layer structure layer of the airplane data organization structure is constructed according to airplane models, sections, systems, subsystems and subsystems.
For a particular aircraft model, the top layer structure layers are relatively stable and invariant after the requirements, functional characteristics and physical characteristics of the top layer of the aircraft have been determined, but these structures can be divided into "product invariant portions" and "product variant portions" according to the content. The data organization corresponding to the invariant portion and the variant portion is consistent. The top layer structure layer is used for organizing and managing common and common information of the same model.
The top layer structure layer is divided through a system contained in the airplane, and then is divided through the sections from the space, so that the division of labor in the actual development process can be effectively realized, and the control of the division size of future modules is facilitated. Each specialty faces a section together, designs cooperatively and completes the overall delivery. In order to reasonably support the difference characteristics of professional delivery data under the sections, the sections are further divided through subsystems, and the division of the subsystems completely depends on professional collaborative division of labor during actual development work. At the same time, the division of subsystems/subsystems effectively controls the size of the configuration layer modules.
Step two: constructing a state control layer of an airplane data organization structure according to the top layer structure layer;
specifically, each subsystem is divided into a group of configuration items CI;
each configuration item CI corresponds to one or more configuration plans CS;
each configuration scheme CS corresponds to one or more modules;
the content of the state control layer does not relate to the information of the part production, and mainly comprises the configuration management and the configuration change control management of the module, and is used for carrying out the management of multiple configurations and single shelf times. "product-invariant part", i.e. a part that is suitable for all stands, without the presence of multiple configurations; the "product variable part" is a part with different configurations selected according to different frame times, namely a part corresponding to a plurality of modules to be selected.
It should be noted that the state control layer follows the definition of the configuration layer in the aircraft universal data organization structure, and is composed of three parts, namely: configuration items CI, configuration scheme CS and modules.
The configuration item CI is a node which plays a role in configuration management and control in a data organization structure, the CI is not a real physical assembly or part in the data organization structure, and each CI is unique and has a specific position in the airplane;
the configuration scheme CS is used as an implementation scheme of the configuration item CI and is controlled by scheme planning in the design process. According to the actual design requirement, N configuration schemes can exist in one configuration item. According to the project configuration business process, a configuration item CI-configuration project CS is selected for supporting the serialized project and customer project of the aircraft.
A module is a design solution of a configuration solution CS in a certain specific shelf range, and includes complete information (number of components, drawing documents, component lists, design specifications) of the design solution. From the perspective of business, the delivery states of the same module corresponding to different shelves may be different, and under the guidance of the core idea that multiple versions are effective, different delivery sets of the same module under different shelves are distinguished through a 'configuration baseline', that is, different versions of the same module are corresponding to different shelf deliveries.
Step three: constructing a part design layer of the airplane data organization structure according to the state control layer;
specifically, the part design layer corresponding to each module comprises a three-dimensional digital-analog model, a two-dimensional pattern, an engineering bill of materials (EBOM) and a design file.
The part design layer is composed of a specific three-dimensional digital-analog, a specific two-dimensional pattern, a specific engineering bill of materials (EBOM) and a specific design file, and is organized by modules. The part design layer is only used for expressing the production guide information, and does not express other management information such as applicable shelves.
The component design layer is a module, the following structure thereof and related design files, and is mainly used for delivery management of the design at the stage. Based on the idea of modular design, the delivery of one module is uniformly managed as a delivery whole.
Step four: and selecting a corresponding airplane data organization structure according to different airplane data management environments.
The airplane data management environment comprises a configuration management environment, a prototype design environment and an airborne equipment management environment.
In practical applications, in a product data management system (PDM), different environments are customized for different data, respectively. And aiming at different service characteristics of configuration items and components, different management modes are adopted.
In summary, the invention provides a layering method of an airplane data organization structure, and relates to the field of airplane digital product data management. The basic principle of the layering method of the airplane data organization structure is that the organization mode of the data and documents of the airplane and parts thereof is consistent with the assembly relationship of the airplane and the parts, the airplane comprises parts and parts, the parts comprise lower-level parts and parts, and the parts are continuously refined according to the form to form a tree structure, namely a data organization structure tree. The method has the advantages that the complex airplane system can be decomposed into a plurality of independent and related modules and used as the object of configuration management, namely, management work is implemented under a flattened data organization structure, and the design and manufacturing level of the airplane is greatly improved.
