Description

Technical Field

[0001] The present invention relates to the field of material data management, and in particular to a method and device for constructing and sharing a full life cycle material library based on object-oriented modeling, which is mainly used for unified modeling, data analysis, and shared use of material data. Background Art

[0002] Materials databases are becoming increasingly mature, becoming more networked, standardized, integrated, intelligent, and commercialized. As platforms for data sharing, development, and application in materials research, production, and application, materials database systems have become foundational technologies and strategic resources for technological development worldwide, playing an increasingly important role. Materials data are crucial for the design, manufacture, use, and disposal of products and structures. While current materials informatics has generated vast amounts of high-quality material property data, these datasets are fragmented, often incomplete, difficult to access and integrate simultaneously, and suffer from limited reusability.

[0003] With the rapid development of my country's aircraft development capabilities, aircraft design, modification, and upgrades are placing greater and higher demands on material performance, creating an urgent need for an engineering materials database system tailored to the specific characteristics of the industry. To this end, research and development units have developed several specialized material database systems, which have played a significant role. With the development of the digital age, the current material library management model and system have revealed many drawbacks: First, the availability of material data is scattered and incomplete. Different material databases are often maintained and accessed between departments. There is a lack of coherent and comprehensive material data, which makes it difficult to effectively reuse it throughout the life cycle; Second, material data collects a large amount of material property measurement results through measurement data. These data are stored in measurement equipment, but the performance data of materials of the same type are not integrated, and there is no unified management, analysis, visualization and storage of data, resulting in a lack of accessibility of effective material data; Third, new materials and new applications are growing explosively. The current material library has poor scalability, and the cost of maintaining the new properties contained in new materials is high, resulting in poor availability of new materials; Fourth, material data is characterized by accuracy and diversity. The use of data analysis methods and tools is of great significance for the efficient and accurate use of material data, but material experts often lack ontological methods. The lack of material ontology development and data analysis support tools hinders the exploration of the potential of material data. Summary of the Invention

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] The present invention implements a method and apparatus for constructing and sharing a full-lifecycle material library using object-oriented modeling. To make the aforementioned objectives, features, and advantages of the present invention more readily apparent, the following embodiments are based on the technical solution of the invention and provide detailed implementation methods and specific implementation processes. However, the scope of protection of the present invention is not limited to the following embodiments.

[0030] See also Figure 1 , which is a flow chart of an embodiment of the object-oriented modeling full life cycle material library construction and sharing method provided by the present invention. Figure 1 Describe the method. Figure 1 As shown, the method includes the following steps:

[0031] S101: Construct material ontology and determine material entities and material properties.

[0032] Step S101 may include:

[0033] Construct materials, material properties and their classification, and clarify the concepts and hierarchical relationships in the field of materials;

[0034] Create a material data structure for the material entity;

[0035] Construct the mapping relationship between material properties and materials;

[0036] Initialize the material library based on the material data structure.

[0037] According to the relevant material standards and the material data classification requirements of the design institute, the material property classification includes main categories and detailed categories. The main categories include body materials, auxiliary materials, and finished product materials. The detailed categories include metal materials, non-metallic materials, and composite materials. Material categories can be flexibly configured and added according to needs.

[0038] Each material corresponds to a unique code, which is used to digitally express material information, supporting the identification and use of material data in product design, process design, and material quota compilation. The material coding rule is based on the different attributes of the selected material type, material brand, material variety, material supply status, material specifications, material technical standards, and material manufacturer. The codes corresponding to different attributes are automatically combined to form a material instance code. The material code is 12 digits in total, consisting of a type code, brand number, variety code, status code, specification code, standard code, manufacturer code, and spare code, totaling 12 digits. For example, Figure 2 shown. Figure 2 This is a schematic diagram of material classification and classification code encoding rules. A material instance contains at least basic material information such as material type, material brand, material variety, material specification, material status, standard, and manufacturer.

[0039] Figure 2 The interpretation of each material classification code shown in is shown in Table 1.

[0040] Table 1 Material number explanation

[0041]

[0042] The information content of materials varies according to their categories and performance parameters, and different materials have different properties. Common properties are sorted out according to material classification, such as Figure 3 Shown is the classification of properties included in metal-type materials.

[0043] The properties of metal materials include at least overview, physical and chemical properties, mechanical properties, sustained and creep properties, fatigue properties, elastic properties, fracture properties, process properties and requirements, organizational structure, etc.

[0044] Create a data structure for the material entity, including name, type, classification code, version and other information; associate material attributes with the material entity; initialize the material library based on the configured material data structure, such as Figure 4 As shown, Figure 4 This is a schematic diagram of the material library initialization process based on the material ontology.

[0045] S102: Integrate heterogeneous material databases, instantiate material ontology, and build a unified material library based on material ontology.

[0046] This step may include:

[0047] Material instance entry and automatic coding;

[0048] Undertake heterogeneous data from different sources and in different forms to establish a cross-platform collaborative material database;

[0049] Collect information on material performance properties;

[0050] Catalogue of construction materials;

[0051] Provides an application programming interface (API) for external access to material data.

[0052] Input material instances such as T300 / HD03 and high-strength aluminum alloy, and automatically encode the material instances. At the same time, establish a material coding mapping relationship between the OEM and the supporting plant, such as Figure 5 As shown, Figure 5 It is a schematic diagram of the material coding mapping relationship between the host institute and the host factory.

[0053] Taking over heterogeneous data from different sources and in different forms, establishing a cross-platform collaborative material database includes: establishing coding mapping rules between specific material databases and unified material libraries, performing similarity matching based on key fields of material data, to establish automatic conversion and mapping of material codes, thereby establishing a cross-platform collaborative material database.

[0054] By performing similarity matching on key attribute fields, we extract the coding of unified materials from the host institute and downstream manufacturers and suppliers, establish a mapping relationship between the codes, integrate with the CAMS material library (airframe materials) and the material library within Winchill (auxiliary materials), and take over various types of material data from host manufacturers, supporting factories, etc. to establish a cross-platform collaborative material database.

[0055] The material selection catalog serves as a reference for design institutes, process departments, material quota groups, and other departments in selecting materials. It is used for model-based material access control and other purposes. Construction methods include configuration generation based on existing models and incremental addition of single or multiple items. For each model of an airfoil structural component, the catalog is generated by selecting materials that can be used for that model from a unified material library.

[0056] S103: Conduct material data statistics and analysis for the entire life cycle of materials to obtain material selection strategies;

[0057] This step may include:

[0058] Collect product material data and compile statistics on product batch material usage information;

[0059] Comparative analysis of material data;

[0060] Mining data features and patterns to obtain material data usage analysis throughout the entire life cycle;

[0061] Calculation and analysis of material properties.

[0062] Collect product material data and count product batch material usage information, including: obtaining material report data from the design bill of materials EBOM or implementation bill of materials BBOM according to product batches, and counting material usage from the product structure dimension, material type dimension, and product type dimension. Integrate with PDM, XBOM, and material single machine status tracking and control system, obtain material report data from EBOM or BBOM according to machine model batches, compare the differences between design material selection and actual production material selection, and the differences between design material selection, production material selection, and material selection catalog. Figure 3 Statistics and analysis of data from different dimensions. Figure 6 It is a schematic diagram of the material data statistics and analysis process. Figure 6The screenshots in the figure are used to illustrate the steps of obtaining material list data from EBOM\BBOM, and are not intended to show the detailed data on the screen.

[0063] Material data comparison and analysis includes: obtaining design material super-selection by comparing EBOM and material selection catalog, and obtaining production material super-selection and production material modification by comparing EBOM and BBOM.

[0064] The material data comparison analysis also includes: analyzing from the product structure dimension, material type dimension and product type dimension according to the usage scenarios and material data usage requirements at different stages, forming analysis records and rules, and storing relevant conclusions and rule information in a structured manner.

[0065] The comparative analysis of material data includes: counting material usage by product structure, counting material usage by part type, calculating material usage based on data and unit weight, the usage of a specific type of material data in different aircraft product structures, and checking the application trend of a certain material in different flights of the same model.

[0066] Mining data features and patterns yields a full lifecycle material usage analysis. Statistical analysis of material attribute fields reveals the following features and patterns: material usage by product structure, material usage by part type, material usage by data and unit weight, usage of a specific material type across different aircraft product structures, and application trends for a specific material across different aircraft types. Figure 7 It is a schematic diagram of a typical scenario of material data analysis and mining;

[0067] Through material performance calculations, the base value of material data and the material's performance stability Cv value are calculated. Integration with design analysis tools, primarily strength calculation tools such as Nastran and Abaqus, is integrated. The material library provides interface data for all material property information required by analysis tools and maintains relevant material performance analysis data.

[0068] S104: Evaluate and recommend material selection based on material maturity models and data analysis.

[0069] This step may include:

[0070] Build a material maturity model;

[0071] Construct a materials engineering selection evaluation model;

[0072] Get the current material usage context information;

[0073] Through the material maturity model and material engineering selection evaluation model, the candidate materials are analyzed and evaluated, and material selection guidelines and material use conclusions are provided.

[0074] In one embodiment, the material maturity model includes a material selection maturity model and a material performance maturity model.

[0075] Build a material maturity model, classify material data analysis results, and establish a material performance maturity model. Define different maturity evaluation technical factors for specific material categories, such as airframe materials and auxiliary materials, determine the weight of each technical factor, apply maturity evaluation standards, and calculate the material maturity level. Figure 8 It is a schematic diagram of material maturity calculation.

[0076] Assume that the material maturity level is MM, the technical evaluation level is TRL, and the weight of the technical factors is , the material maturity level calculation formula is as follows:

[0077] ,

[0078] in, is the number of technical factors, is the current count, representing the kth technical factor.

[0079] The material engineering selection evaluation dimensions in the material engineering selection evaluation model include material performance, technical maturity, guarantee capability, economic affordability, material selection strategy, etc. The evaluation criteria for each dimension are defined to form an evaluation model.

[0080] For airfoil structural components, obtain part design requirements, including material density , material yield strength , material elastic modulus Based on the results of the full-process data analysis, the material data adoption trend was predicted, and a data set of candidate materials for airfoil structural components was obtained {T300 / HD03, T700 / HD03, carbon / titanium super hybrid composite, T300 / 4211, T700 / 4211, high-strength glass fiber / 4211, high-strength aluminum alloy}. According to the maturity data of material selection at different stages, and taking into account factors such as material performance applicability, technical maturity, capability guarantee, economic affordability, and usage patterns, the optimal choice was finally calculated to be T300 / HD03. Figure 9 It is a schematic diagram of the material selection analysis of airfoil structural components.

[0081] The constructed unified material library can be integrated with the PDM system to obtain information such as component material selection, change, deviation, etc.; integrated with the enterprise ERP to obtain supplier material information and material master data; integrated with the material stand-alone status tracking and control system to obtain material stand-alone status information; integrated with the xBOM system to obtain material production and usage data; integrated with CAD software to provide selection range data, various design modes such as main material, auxiliary material, composite material parameters, and provide material selection verification; integrated with CAE software to provide material parameter information.

[0082] In summary, the highly available full-life cycle material library construction and sharing method of the present application, by constructing a unified material library that supports the integration and collaboration of heterogeneous material libraries through the construction of a material ontology, analyzes the usage of materials throughout the life cycle to obtain material selection rules, predicts the trend of material data adoption, and faces the material usage needs throughout the life cycle. Based on the maturity of materials at each stage and various factors, the material data is compared and summarized to provide material selection guidelines and material use conclusions. Therefore, the highly available full-life cycle material library construction and sharing method described in the present application can solve the problems of unified modeling, data analysis, and shared use of material data, and use material data accurately and efficiently.

[0083] Based on the above method embodiment description, this application also provides a corresponding full life cycle material library construction and sharing device embodiment.

It can define different material property templates according to the characteristics of material data and insert pre-defined material properties into the templates.

[0086] The unified material library management module maintains heterogeneous material library instances, including basic material data management, material instance catalog management, and material selection scope management.

[0087] The data analysis module is used for material data query and analysis, including analysis of acquired material information by model and flight. This analysis is divided into three main dimensions: product material selection statistics, material citation statistics, and material selection statistics for different part types. It also supports performance data calculation, including Cv value and data base value calculation functions, and a statistical calculation interface.

[0088] The data evaluation module, used for material selection, includes: establishing a material data evaluation system, building a material selection maturity model based on the evaluation system and the material library data usage classification.

[0090] In summary, the full-lifecycle materials library construction and sharing device proposed in this application completes cross-platform material data definition, establishes a unified data structure, and forms a unified, cross-platform collaborative materials database.
