All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
It should be noted that the terms "first," "second," and the like in the description and claims of the present invention and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are capable of operation in sequences other than those illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
In accordance with an embodiment of the present invention, there is provided a method embodiment of a method for defining product features and model mappings, it being noted that the steps illustrated in the flowchart of the drawings may be performed in a computer system such as a set of computer-executable instructions and that, although a logical order is illustrated in the flowchart, in some cases, the steps illustrated or described may be performed in an order different than here.
FIG. 1 is a flowchart of a method for defining product features and model mappings according to an embodiment of the present invention, as shown in FIG. 1, the method including the steps of:
step S102, determining a product configuration corresponding to a simulation model of a product, wherein the product configuration comprises a hierarchical structure and a spatial relationship of parts of the product;
step S104, respectively determining the mapping relation between the product configuration and a plurality of different simulation models of the product, wherein the plurality of different simulation models are respectively established in different simulation systems of the product, and the plurality of simulation models comprise a first simulation model and a second simulation model of both the feature mapping parties;
and step S106, mapping the characteristics of the first simulation model to the second simulation model according to the mapping relation.
Through the steps, the product configuration corresponding to the simulation model of the product is determined, wherein the product configuration comprises the hierarchical structure and the spatial relationship of the parts of the product; respectively determining the mapping relation between the product configuration and a plurality of different simulation models of the product, wherein the plurality of different simulation models are respectively established in different simulation systems for the product, and comprise a first simulation model and a second simulation model of both characteristic mapping parties; according to the mapping relation, the first simulation model and the second simulation model which cannot directly establish an effective mapping relation are mapped by using a mode of mapping the characteristics of the first simulation model onto the second simulation model by using a product configuration as an intermediate node, so that the purpose of effectively establishing the mapping relation between different simulation models is achieved, the technical effect of performing characteristic mapping between the simulation models of different simulation systems is realized, and the technical problems that the characteristic mapping cannot be directly performed between the simulation models of different simulation systems, the characteristic matching needs to be performed manually, the efficiency is low, and the accuracy is poor are solved.
The product configuration may include a hierarchical structure and a spatial relationship of product parts, where the hierarchical structure may refer to hierarchical division of the product parts, for example, taking an airplane as an example, the whole airplane is a first level, the airplane includes a second level such as a wing, a fuselage, an empennage, a landing gear, a power device, etc., the wing includes a third level such as an aileron and a flap, the aileron may further include other parts such as a housing and a screw, and it should be noted that the other parts may also be classified. The hierarchy may indicate logical relationships between different parts. The spatial relationship may be that between a plurality of different parts of the product, including the connection relationship and the positional relationship, for example, the connection relationship may include a number 1-10 screw to secure the flap to the body, and the positional relationship may include the seat being mounted above the floor. The product configuration may also include temporal relationships, such as the sequence of actions of the different parts, the sequence of installations of the different parts, or the sequence of analyses of a simulation model of the product. The product configuration typically varies from product to product.
When determining the mapping relationship between the product configuration and a plurality of different simulation models of the product, the simulation models of the same product established in different simulation systems look similar, but the attached information of each component is different, and the components cannot be directly copied and transferred through the mapping relationship. For example, material information may be set in different parts in the CAD system, and when a model in the CAD is transferred to the CAE system, the accompanying information disappears, and the model needs to be set again in the CAE system, so that the attribute information of the simulation model in the CAD system cannot be directly copied and transferred to the CAE system.
The product configuration and the plurality of different simulation models are mapped, and when the product configuration and the simulation models are mapped, the mapping can be performed according to the parts in the product configuration, for example, taking an airplane as an example, a tail wing comprises a flat wing and a vertical wing, the attribute information of the flat wing can be mapped with the flat wing in the product configuration, the attribute information of the vertical wing can be mapped with the vertical wing in the product configuration, or the flat wing and the vertical wing in the tail wing can be mapped with the flat wing and the vertical wing in the product configuration. It should be noted that the minimum unit in the product configuration may be different from the minimum unit of the simulation model, and therefore, there may be a mapping relationship between one party and another party in multiple units. In addition, the same part can be divided into different units, and a mapping relationship can be established by combining a plurality of units on one side and a plurality of units combined with the other side.
The first simulation model may be a party having features, the second simulation model may be a party to be mapped with features, the first simulation model and the second simulation model may be both one, and features of one first simulation model are both mapped in one second simulation model. The first simulation model may be a plurality of first simulation models, the second simulation model may be one second simulation model, and features of a plurality of different first simulation models are mapped onto the same second simulation model. The first simulation model and the second simulation model may be plural, and the characteristics of the plural first simulation models should be provided on the plural second simulation models.
Optionally, the respectively determining the mapping relationships between the product configuration and the plurality of different simulation models includes: respectively determining a plurality of composition units which form the simulation model; and establishing a mapping relation between the component units and the parts of the product configuration.
The above-mentioned components of the simulation model are not used in different simulation models, for example, in a CAD system, the smallest unit of the simulation model is a part, such as a screw, a casting, etc., in a CAE system, the whole simulation model is divided into grids, and each specific part is divided into grids according to the division rule. Therefore, it is necessary to determine the constituent units of the simulation model, and the constituent units may be determined by dividing the component units of the product configuration.
Optionally, mapping the features of the first simulation model onto the second simulation model according to the mapping relationship includes: according to the mapping relation, mapping the characteristics of one component unit of the first simulation model to one part of the second simulation model; or, according to the mapping relation, mapping the characteristics of a plurality of composition units of the first simulation model to a part of the second simulation model; or mapping the characteristics of a plurality of component units of the first simulation model to a plurality of parts of the second simulation model according to the mapping relation.
The mapping of the features of the first simulation model to the second simulation model includes mapping the product configuration and the features of the first simulation model to the database for storage through the mapping relationship, and then mapping the features in the database to the second simulation model according to the product configuration and the mapping relationship. Specifically, the mapping the features of the first simulation model to the second simulation model according to the mapping relationship may include: acquiring attribute information of a first component unit of the first simulation model according to a first mapping relation between the first simulation model and the product configuration; storing the attribute information of the first composition unit according to the product configuration; and mapping the attribute information of the first composition unit to a second composition unit of the second simulation model according to a second mapping relation between the second simulation model and the product configuration.
Optionally, the storing the attribute information of the first component unit according to the product configuration includes: determining a storage data structure of a plurality of attribute information according to the hierarchical structure of the product configuration; and storing the plurality of attribute information according to the storage data structure.
Optionally, the attribute information includes at least one of the following: material information, dimensional information, load information, constraint information.
Different simulation models have different attribute information, and in different simulation models, the simulation environments are different, the set parameters are different, and the specific attribute information is also different. The material information includes the material of the part, the configuration ratio of the material, and the physical parameters of the material, such as hardness, density, mass, etc. The size information includes the distance, thickness, radian, length and the like from other parts. The load information includes a point load, a line load, a surface load, and the like. The constraint information includes hinge constraint, flexible body constraint, fixed constraint, etc.
Before mapping the features of the first simulation model onto the second simulation model according to the mapping relationship, the method further includes: receiving a mapping instruction, wherein the mapping instruction is used for indicating that the characteristics of the first simulation model are mapped to the second simulation model.
The mapping instruction is sent by a user or triggered by a software mapping condition. Indicating that mapping is required in this case. The timeliness of mapping is effectively improved, and therefore the mapping efficiency is improved.
Optionally, the characteristics of the first simulation model include: a first feature of the first simulation model and a second feature of the product configuration of the first simulation model.
The first simulation model has characteristics, and the product configuration of the first simulation model also has characteristics, and the characteristics of the first simulation model are taken as first characteristics, and the characteristics of the product configuration of the first simulation model are taken as second characteristics. When the features of the first simulation model are mapped to the second simulation model, the first features of the first simulation model and the second features of the first simulation model can be mapped to the second simulation model, and the mapping efficiency is improved.
It should be noted that the present application also provides an alternative embodiment, which is described in detail below.
The present embodiment relates to product design and manufacturing software. The product design software mainly refers to product design management software, and the current market mainly comprises TDM (time division multiplexing), PLM (product quality modeling) and PDM (product data management), and lean research and development and design process management software; the manufacturing software of the product mainly refers to software involved in the manufacturing process of the product, such as MES which is popular in the market, and comprises management modules of manufacturing data management, planning and scheduling management, production scheduling management, inventory management, quality management, human resource management, work center/equipment management, tool and tool management, purchasing management, cost management, project board management, production process control, bottom layer data integration analysis, upper layer data integration decomposition and the like.
With the development of technology, the design to manufacture and the subsequent operation and maintenance related software of the current products are independent, and how to connect them in series through a whole set of software system becomes a great trend.
In design, the CAD system has excellent geometric modeling function and CAE excellent analysis and calculation function. The applications of CAD and CAE have remained isolated to date. They often interact with information at a geometric level, and more cumbersome information requires manual intervention. It is difficult to implement unified integrated execution from design to analysis.
In manufacturing, MES is now commonly used. The MES location is an execution layer between the planning layer and the field automation system, and is mainly responsible for the production management and scheduling execution of the workshop. The product is a two-dimensional code in the MES, and the product is only carried by the two-dimensional code, so that the information content is far from enough. This requires the introduction of product configuration concepts.
The specific process is as follows:
firstly, product refinement, which is realized by a product configuration concept, and the product configuration is carried out throughout the whole process of design and manufacture of the product. Fig. 2 is a schematic view of a product configuration according to an embodiment of the present invention, as shown in fig. 2, the product configuration is a structural form of the product.
1) The product configuration has a hierarchical structure. The products are initially made up of components, which are assemblies, which are made up of parts. The parts are in turn composed of cells having a cell configuration or the like.
2) The product configuration has a spatial ordering. The products are composed of the most basic elements (units). The elements have relative position relation, the upper part, the lower part, the left part and the right part of one element are all composed of fixed elements, and the positions of the elements are fixed.
3) The product configuration has a time ordering. The analysis and calculation of some parts of the product are in chronological relationship. The time sequence is not chaotic and has a certain precedence relationship, and the analysis component 1 and the analysis component 2 can be analyzed at a certain moment.
4) The product configuration has the same composition structure form but different expression form in a specific field. Fig. 3 is a schematic view of a product configuration of an aircraft according to an embodiment of the invention, such as the product configuration of fig. 3, if the product is an aircraft, having wings, fuselage, tail, landing gear and power plant.
The wing is composed of an aileron and a flap;
the fuselage comprises a front fuselage body, a middle fuselage body and a rear fuselage body;
the tail comprises a horizontal tail (horizontal tail) and a vertical tail (vertical tail);
the landing gear is also called as landing and generally consists of a shock absorption strut and a wheel;
the power device mainly refers to an engine.
And secondly, mapping the product configuration and the model configuration. The parts of the product configuration contain unit, configuration (material configuration, load configuration, etc.) information, but their information is discrete. No analysis and calculation is done in the product configuration. Its configuration remains substantially unchanged during the various stages of development of the product. The model configuration has cells, configurations, loads, analyses and results. CAD and CAE correlation analysis can be performed in model configuration. The product configuration and the model configuration are related by product type. The model configuration, in addition to storing the topology of the product, also has data information of different stages of the product, including the design stage and the manufacturing stage. The product data of different stages can be traced back to the model configuration through the product configuration.
And thirdly, the CAD and the CAE realize information intercommunication through product configuration. The parts of the CAD model are first associated with the product configuration, and then the elements of the CAE model are then associated with the product configuration. The mapping between CAD and CAE is realized by the product configuration of the bond.
Fig. 4 is a schematic view of a product configuration of an equipment bay section of an aircraft according to an embodiment of the invention, as shown in fig. 4, a configuration diagram of a certain equipment bay section of an aircraft. The cabin section of the equipment is divided into a front cabin section, a middle cabin section and a rear cabin section. Fig. 5 is a schematic diagram of a CAD model of an equipment bay section of an aircraft according to an embodiment of the invention, as shown in fig. 5, which is a CAD model with some CAD geometric and material properties. The mapping is performed by the configuration of the equipment and the CAD model of the equipment, which is the front bay section, the middle bay section, and the rear bay section, respectively, from left to right in the figure.
Fig. 6 is a schematic diagram of a CAE model of an equipment bay of an aircraft according to an embodiment of the present invention, as shown in fig. 6, which is a CAE model that is also associated with the configuration of equipment and is divided into a plurality of different regions according to different dividing lines, and in the diagram, the equipment bay of the aircraft is divided into three bays according to two dividing lines, namely, a front bay.
When CAE analysis is carried out on the equipment bay, the CAE model does not need to be subjected to characteristic assignment, because the CAD model is already provided. And acquiring related material characteristics from the corresponding CAD model according to the mapping relation of the configuration, and performing CAE (computer aided engineering) related analysis. The conversion from CAD to CAE is easily realized through the concept of configuration, the problem of unified integration from design to analysis is solved, the labor is reduced, and the progress in the design field is realized.
