Description

Technical Field

[0001] This invention relates to a method for integrating all elements of a complex equipment digital prototype with a flexible architecture, belonging to the field of aerospace equipment design technology. Background Technology

[0002] In the development of complex equipment systems, the use of digital prototype virtual simulation technology can build a large number of schemes in batches, which can cover the virtual verification of various schemes for equipment digitization. This provides a large number of samples for finding the optimal solution, which can significantly reduce trial and error costs and shorten the development cycle. It is a core technical means to improve the efficiency and quality of equipment development.

[0003] However, digital prototypes are often limited to a single professional field (such as mechanical or electronic), making it difficult to cover multi-level (system, subsystem, equipment, etc.) and full-element scenario collaborative simulation. Meanwhile, low standardization of system interfaces leads to difficulties in data interoperability, insufficient model reusability causes redundant development, and the integration process faces technical barriers due to poor compatibility of heterogeneous models. These problems make cross-professional and cross-level full-system verification difficult to achieve, necessitating the construction of a flexible digital prototype architecture to improve the reusability and replaceability of prototype components and interfaces, thereby enhancing the overall efficiency of digital prototype design verification. Summary of the Invention

[0004] The technical problem solved by this invention is: addressing the problems in the existing technology, such as the failure of digital equipment design to cover all elements and multiple levels, low standardization of interfaces between systems, insufficient reusability of models, and difficulty in integration, a flexible architecture-based method for integrating and fusing digital prototypes of complex equipment with all elements is proposed.

[0005] The present invention solves the above-mentioned technical problem through the following technical solution:

[0006] A method for integrating and fusing all elements of a complex equipment digital prototype with a flexible architecture, comprising:

[0007] Define the digital prototype components required for aerospace equipment under a flexible architecture;

[0008] Classify the types and components installed within aerospace equipment and obtain component classification information;

[0009] Based on the component classification information, the interfaces of each type of component are classified and processed.

[0010] Based on the interface classification information and component classification information of each model component, the overall performance model component library is constructed using the Modelica language;

[0011] By utilizing the model types and interface types integrated in the overall performance model component library, a concrete equipment simulation model that meets the integration requirements of flexible architecture equipment is constructed.

[0012] Based on the requirements for flexible architecture equipment integration, the requirements indicators and dynamic models of aerospace equipment components are obtained. The requirements indicators are assigned to the concrete equipment simulation model, and the dynamic model is integrated into the concrete equipment simulation model.

[0013] The initial solution data is used as input data to input into the concrete equipment simulation model for data fitting and training, so as to obtain a full-element digital model.

[0014] The digital prototype components required for the flexible architecture equipment include a set of prototype requirement models, prototype 3D configuration models, prototype overall performance models, and prototype physics models, as well as prototype test data. The model set uses the Modelica model as the base architecture for integrating other models. The prototype requirement model is expressed using the ReqIF standard. The prototype 3D configuration model is expressed using the Step format. The prototype multiphysics model is constructed using commercial software.

[0015] Apart from the overall performance model of the prototype, other models are selected based on the integration requirements of flexible architecture equipment.

[0016] The aforementioned model components refer to all components installed within aerospace equipment. The classification is based on a specific hierarchical classification according to the component structure and function. After a first-level classification according to the component structure, all categories within the first level are classified into a second level according to the usage scenario or specific function. The number of classification levels is determined based on the sub-components obtained after decomposing each model component. The component classification information is displayed in the form of a tree diagram.

[0017] The interface classification information of each type of component is displayed in the form of a tree diagram. When modeling interfaces based on the tree diagram, the interfaces of the parent node type and the interfaces of any child node type are determined respectively. The interface modeling principle is that the interface of the parent node type is connected to the interface of any child node type as needed, the interfaces of the same child node type are connected to each other, and there are no connections between other interfaces. The tree diagram includes tree nodes and leaf nodes. The two types of nodes include parent nodes and corresponding child nodes.

[0018] The overall performance model component library is based on the prototype overall performance model. It designs generalized external interfaces corresponding to generalized models and concrete external interfaces corresponding to concrete models. According to the integration requirements of flexible architecture equipment, it integrates other types of models and replaces the aerospace equipment component types corresponding to the generalized models with the aerospace equipment component types corresponding to the concrete models in situ to realize the construction of flexible architecture. After integrating and designing the required concrete models according to the integration requirements of flexible architecture equipment, the concrete equipment simulation model is completed.

[0019] The component classification information and interface classification information tree diagram, as well as the overall performance model component library, are all constructed using the Modelica language. The overall performance model component library includes generalized models and materialized models, which correspond to generalized aerospace equipment components and materialized aerospace equipment components, respectively. In the dual tree diagram, non-leaf nodes represent the generalized models and generalized nodes corresponding to the generalized aerospace equipment components, while leaf nodes represent the materialized models and corresponding materialized nodes corresponding to the materialized aerospace equipment components.

[0020] The aerospace equipment components corresponding to the child nodes of the tree structure inherit from the aerospace equipment components corresponding to the parent nodes, and all of them are implemented through the Modelica keyword extends.

[0021] The method for obtaining demand indicators and dynamic models of aerospace equipment components is as follows:

[0022] Extract the analytical requirement model and the analytical 3D model from the overall performance model component library respectively;

[0023] The requirements for flexible architecture equipment integration are analyzed using an analytical requirement model to obtain requirement indicators;

[0024] The aerospace equipment components that meet the integration requirements of flexible architecture equipment are analyzed using analytical 3D models to obtain the corresponding dynamic models.

[0025] The analytical requirement model adopts the analytical ReqIF requirement model. After analyzing the integration requirements of flexible architecture equipment, the relationship between the requirement model indicators and the overall performance model parameters is established based on the analysis results. After being assigned preset values, the model is integrated into the concrete equipment simulation model.

[0026] The analytical 3D model adopts the analytical Step 3D model, and uses Modelica to simulate the mechanical transmission part of the aerospace equipment component, obtains the dynamic model with a concrete interface, and integrates it into the concrete equipment simulation model.

[0027] The method for obtaining the initial solution data is as follows:

[0028] The initial solution data is categorized into two types: the solution part and the visualization part.

[0029] Historical multiphysics simulation data of current aerospace equipment components are collected as input, and a multiphysics solution model is generated after data fitting.

[0030] Set up a multiphysics visualization module, use historical multiphysics simulation data as input, drive animation display, and obtain a multiphysics visualization model;

[0031] The multiphysics solution model and the multiphysics visualization model are combined and integrated into the concrete equipment simulation model.

[0032] The advantages of this invention compared to the prior art are:

[0033] (1) The present invention provides a flexible architecture for the integration and fusion of all elements of digital prototype of complex equipment. The components and interfaces are classified in a tree diagram manner, and an abstract and concrete Modelica model library is constructed according to the classification. It is more in line with business knowledge and can build a flexible architecture based on the object-oriented features of Modelica through abstract components and interfaces, so that the architecture has the ability to be replaced in place and improves the reusability of the architecture.

[0034] (2) This invention integrates requirements, geometry, multiphysics, and data models based on a flexible architecture, and abstracts and concretizes the integrated elements to form a model library. It supports in-situ replacement between elements and can iterate and improve based on a unified flexible architecture in the stages of scheme demonstration, design, and virtual experimentation, ensuring the consistency and traceability of data at different stages.

[0036] A flexible architecture-based method for integrating and fusing full-element digital prototypes of complex equipment is proposed. This method defines the constituent elements of the digital prototype, hierarchically analyzes and classifies all types of components and interface types included in the complex equipment, and achieves tree-like classification of component and interface information. Then, by establishing a model component library, other models are integrated / fused, and further fusion of the required models is achieved to realize the integrated design of digital prototype components. This method can achieve full-element, multi-level, and standardized inter-system interface coverage of complex aerospace equipment.

[0037] The method for integrating and fusing all elements of a complex equipment digital prototype with a flexible architecture includes the following steps:

[0038] Define the digital prototype components required for aerospace equipment under a flexible architecture;

[0039] Classify the types and components installed within aerospace equipment and obtain component classification information;

[0040] Based on the component classification information, the interfaces of each type of component are classified and processed.

[0041] Based on the interface classification information and component classification information of each model component, the overall performance model component library is constructed using the Modelica language;

[0042] By utilizing the model types and interface types integrated in the overall performance model component library, a concrete equipment simulation model that meets the integration requirements of flexible architecture equipment is constructed.

[0043] Based on the requirements for flexible architecture equipment integration, the requirements indicators and dynamic models of aerospace equipment components are obtained. The requirements indicators are assigned to the concrete equipment simulation model, and the dynamic model is integrated into the concrete equipment simulation model.

[0044] The initial solution data is used as input data to input into the concrete equipment simulation model for data fitting and training, so as to obtain a full-element digital model.

[0045] The digital prototype components required for flexible architecture equipment include a prototype requirement model, a prototype 3D configuration model, a prototype overall performance model, a prototype physics model, and prototype test data. The model set uses the Modelica model as the base architecture for integrating other models. The prototype requirement model is expressed using the ReqIF standard, the prototype 3D configuration model is expressed using the Step format, the prototype multiphysics model is constructed using commercial software, and the prototype test data is initial solution data expressed in CSV format.

[0046] Apart from the overall performance model of the prototype, other models are selected based on the integration requirements of flexible architecture equipment.

[0047] Model components refer to all components installed within aerospace equipment. The classification is based on the component structure and function, with each component being classified at a specific level. After the first level of classification is based on the component structure, all categories within the first level are classified at a second level according to the usage scenario or specific function. The number of classification levels is determined based on the sub-components obtained after decomposing each model component. The component classification information is displayed in the form of a tree diagram.

[0048] The interface classification information of each component model is displayed in the form of a tree diagram. When modeling interfaces based on the tree diagram, the interfaces of the parent node type and the interfaces of any child node type are determined respectively. The interface modeling principle is that the interface of the parent node type is connected to the interface of any child node type as needed, the interfaces of the same child node type are connected to each other, and there are no connections between other interfaces. The tree diagram includes tree nodes and leaf nodes. Both types of nodes include parent nodes and corresponding child nodes.

[0049] The overall performance model component library is based on the prototype overall performance model. It designs the generalized external interface corresponding to the generalized model and the concrete external interface corresponding to the concrete model. According to the integration requirements of flexible architecture equipment, it integrates other types of models and replaces the aerospace equipment component types corresponding to the generalized models in situ with the aerospace equipment component types corresponding to the concrete models to realize the construction of flexible architecture. After integrating and designing the required concrete models according to the integration requirements of flexible architecture equipment, the concrete equipment simulation model is completed.

[0050] The component classification information and interface classification information tree diagram, as well as the overall performance model component library, are all built using the Modelica language. The overall performance model component library includes generalized models and materialized models, which correspond to generalized aerospace equipment components and materialized aerospace equipment components, respectively. In the dual tree diagram, non-leaf nodes represent the generalized models and generalized nodes corresponding to the generalized aerospace equipment components, while leaf nodes represent the materialized models and corresponding materialized nodes corresponding to the materialized aerospace equipment components.

[0051] The aerospace equipment components corresponding to the child nodes of the tree structure inherit from the aerospace equipment components corresponding to the parent nodes, all of which are implemented using the Modelica keyword `extends`.

[0052] The method for obtaining demand indicators and dynamic models of aerospace equipment components is as follows:

[0053] Extract the analytical requirement model and the analytical 3D model from the overall performance model component library respectively;

[0054] The requirements for flexible architecture equipment integration are analyzed using an analytical requirement model to obtain requirement indicators;

[0055] The aerospace equipment components that meet the integration requirements of flexible architecture equipment are analyzed using analytical 3D models to obtain the corresponding dynamic models.

[0056] The analytical requirement model adopts the analytical ReqIF requirement model. After analyzing the integration requirements of flexible architecture equipment, the relationship between the requirement model indicators and the overall performance model parameters is established based on the analysis results. After being assigned preset values, the model is integrated into the concrete equipment simulation model.

[0057] The analytical 3D model adopts the analytical Step 3D model, and uses Modelica to simulate the mechanical transmission part of the aerospace equipment component, obtains the dynamic model with a concrete interface, and integrates it into the concrete equipment simulation model.

[0058] The method for obtaining the initial solution data is as follows:

[0059] The initial solution data is categorized into two types: the solution part and the visualization part.

[0060] Historical multiphysics simulation data of current aerospace equipment components are collected as input, and a multiphysics solution model is generated after data fitting.

[0061] Set up a multiphysics visualization module, use historical multiphysics simulation data as input, drive animation display, and obtain a multiphysics visualization model;

[0062] The multiphysics solution model and the multiphysics visualization model are combined and integrated into the concrete equipment simulation model.

[0063] The following description, in conjunction with the accompanying drawings and preferred embodiments, provides further details:

[0064] In the current embodiment, such as Figure 1 As shown, the steps of the integrated fusion method for full-element digital prototypes of complex equipment include:

[0065] Define the components of a digital prototype, including: a prototype requirements model, a prototype 3D configuration model, a prototype overall performance model, a prototype physical field model, and prototype test data. The overall performance model, represented by the Modelica model, serves as the architectural foundation, integrating other models.

[0066] A hierarchical analysis is performed on all the different types of components included in the complex equipment, and these components are categorized to form component classification information.

[0067] For example, the engine category includes XX model engine and YY model engine.

[0068] All component interfaces are categorized to create interface classification information. For example, interface categories include electrical interfaces, thermal interfaces, and mechanical interfaces.

[0069] Based on component and interface classification information, a generalized and specific overall performance model component library is built using the Modelica language. Generalized model components have generalized external interfaces, while specific model components have specific external interfaces. Using the generalized models, a flexible system architecture is constructed, and by replacing specific components in situ, specific simulation models of complex equipment are generated.

[0070] Integration / fusion of other models: By parsing the requirement model, the values ​​of system requirement indicators are obtained and set into the simulation model; by parsing the 3D model, a multibody dynamics model is generated and integrated into the simulation model, and the generated model is labeled; using the simulation results data of the multiphysics model as input, a data model is generated through data fitting and machine learning, and integrated into the simulation model, and the generated model is labeled.

[0071] (1) Define the components of a digital prototype

[0072] Define the components of a digital prototype, including: prototype requirement model, prototype 3D configuration model, prototype overall performance model, prototype physical field model, and prototype test data. The overall performance model is expressed using the Modelica model, which serves as the architecture foundation and is integrated into this foundation.

[0073] The prototype model is expressed using the ReqIF standard, the 3D configuration model of the prototype is expressed using the Step format, the multiphysics model of the prototype is built using mainstream commercial software, and the prototype test data is expressed using the CSV format.

[0074] Apart from the overall performance model of the prototype, other models can be removed as needed;

[0075] (2) Analyze and categorize all types of components included in complex equipment.

[0076] Analyze all types of components included in complex equipment, categorize them, and generate component classification information. This classification information is displayed in a tree diagram format.

[0077] The categorization is based on "X model component belongs to this category". For example: XX model engine and YY model engine are engines; XX model lithium battery and YY model lithium battery are lithium batteries;

[0078] Depending on specific needs, the categories can be further categorized after classification. For example, lithium batteries and storage batteries are battery categories.

[0079] For specific needs, the model components can be further decomposed to form the classification information of sub-components;

[0080] (3) Categorize the interfaces of all component models.

[0081] Analyze the interfaces of all component models, categorize them, and generate interface classification information. This classification information is displayed in a tree diagram.

[0082] According to the tree diagram, when modeling and connecting interfaces, an interface of the parent node type can be connected to an interface of any child node type (including direct child nodes and descendant child nodes); interfaces of the same child node type can be connected; otherwise, they cannot be connected, for example, interfaces of different child node types within the same parent node cannot be connected.

[0083] (4) Construct a flexible framework based on component and interface classification information.

[0084] Based on the tree structure information categorized by components and interfaces, use the Modelica language to build an abstract and concrete overall performance model component library;

[0085] Non-leaf nodes correspond to abstract model components / interfaces, while leaf nodes correspond to concrete model components / interfaces. Abstract model components can only have abstract interfaces, and concrete model components can only have concrete interfaces.

[0086] In a tree structure, the components corresponding to child nodes inherit from the components corresponding to parent nodes, which is achieved using the Modelica keyword `extends`.

[0087] The flexible framework is built from abstract components, and generates a concrete simulation model of complex equipment by replacing concrete components in situ.

[0088] (5) Integrate / fused other models

[0089] (5-1) By analyzing the ReqIF demand model, the relationship between the demand model indicators and the overall performance model parameters is established, and the values ​​of the system demand indicators are set into the simulation model.

[0090] Use a JSON file to construct the mapping relationship between the requirement model and the overall performance model variables. This includes the relationship ID, the full name of the requirement object variable, and the full name of the overall performance object. The full name is represented by the object name + "." + variable name. If the variable name contains the symbol ".", it is represented by the escape symbol "\". The symbol "\" is represented by "\\".

[0091] (5-2) By analyzing the Step 3D model, a multibody dynamics model is generated and integrated into the simulation model;

[0092] The objects being converted are 3D model objects and kinematic pairs;

[0093] The expression of a 3D model object is hierarchical, and when using Modelica, the hierarchy is consistent with the 3D model.

[0094] In addition to generating the corresponding mechanical objects, the dynamic translational and rotational mechanical parts of the 3D model also need to generate dynamic part models between them. The generated Modelica dynamic model follows the Modelica basic model library. For example, a specific translational joint corresponds to an instance of the Modelica type Modelica.Mechanics.MultiBody.Joints.Prismatic.

[0095] The generated dynamic model, after adding an external interface, is integrated into the already embodied model;

[0096] The generated dynamic models are collected and classified using a tree diagram to construct abstract-concrete models, which are then added to the model library. This ensures that the dynamic models also have an abstract-concrete model library that aligns with business requirements, supporting in-situ replacement.

[0097] (5-3) The integration of multiphysics models is divided into two parts: model solution and visualization.

[0098] The multiphysics model solution section uses multiphysics simulation data as input, first determining the input and output variables in the data; then, it generates a data model through data fitting, machine learning, and other methods. The solution model consists of a solver dynamic library and a Modelica model encapsulated in that dynamic library.

[0099] In the multiphysics visualization section, a multiphysics visualization module was developed, which uses simulation data as input to drive multi-field animation display;

[0100] The generated multiphysics models are collected and classified using a tree diagram. Similarly, abstract-concrete models are constructed and added to the model library.

[0101] Experimental data model integration: consistent with the generation method of the multiphysics solution part.

[0102] This embodiment enables digital prototype model technology that covers all elements, multiple levels, and standardized interfaces between systems in digital equipment design.
