It should be noted that the terms "first," "second," and the like in the description and the claims of the present invention and the above figures are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate such that the embodiments of the invention described herein may be implemented in sequences other than those illustrated or otherwise 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.
According to an embodiment of the present invention, there is provided a method embodiment of a method of defining product features and model mappings, it being noted that the steps shown in the flowchart of the figures may be performed in a computer system such as a set of computer-executable instructions, and, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in an order other than that shown or described herein.
FIG. 1 is a flow chart of a method of defining product features and model mappings, according to an embodiment of the invention, as shown in FIG. 1, the method comprising the steps of:
step S102, determining a product configuration corresponding to the simulation model of the 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 a plurality of simulation models 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 feature mapping parties;
and S106, mapping the features of the first simulation model to the second simulation model according to the mapping relation.
Through the steps, adopting a product configuration corresponding to the simulation model of the product, wherein the product configuration comprises a hierarchical structure and a spatial relationship of 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 a plurality of simulation models 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 feature mapping parties; according to the mapping relation, the features of the first simulation model are mapped onto the second simulation model, the first simulation model and the second simulation model which cannot directly establish an effective mapping relation are mapped by taking the 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 feature mapping between simulation models of different simulation systems is achieved, and the technical problems that feature mapping cannot be directly carried out between simulation models of different simulation systems, feature matching needs to be carried out manually, and 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 components, where the hierarchical structure may refer to a hierarchical division of product components, for example, taking an aircraft as an example, where the aircraft is a first level, the aircraft includes a wing, a fuselage, a tail wing, a landing gear, a power device, and other second levels, the wing includes a third level such as an aileron and a flap, the aileron may further include other parts such as a shell, a screw, and other parts may further be classified. The hierarchy may indicate logical relationships between different parts. The above-mentioned spatial relationship may be a spatial relationship between a plurality of different parts of the product, including a connection relationship including fixing the aileron to the fuselage by screws No. 1 to No. 10 and a positional relationship including mounting the seat on the floor, for example. The product configuration may also include a time relationship such as an order of actions of the different parts, an order of installation of the different parts, or an order of analysis of a simulation model of the product. The product configuration will generally vary from product to product.
In 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 built in different simulation systems look similar, but the attached information attached to each component is different, and the copying and transferring cannot be directly performed through the mapping relationship. For example, material information can be set in different parts of the CAD system, and when a model in the CAD is transferred to the CAE system, the incidental information thereof disappears, and the CAD system needs to be reset, so that the attribute information of the simulation model in the CAD system cannot be directly copied and transferred to the CAE system.
When the product configuration and the simulation models are in mapping relation, mapping can be performed according to the unit of parts in the product configuration, for example, an airplane is taken as an example, the tail wing comprises a flat wing and a vertical wing, the attribute information of the flat wing can be in mapping relation with the flat wing in the product configuration, the attribute information of the vertical wing can be in mapping relation with the vertical wing in the product configuration, and the mapping relation can be formed between the flat wing and the vertical wing in the tail wing and the flat wing and the vertical wing in the tail wing of the product configuration. It should be noted that, since the minimum unit in the product configuration may be different from the minimum unit of the simulation model, there may be a case where one party may establish a mapping relationship with the other party in a plurality of units. The same component may be divided into different units, and a plurality of units may be combined with one another to create a mapping relationship.
The first simulation model may be a party with features, the second simulation model may be a party with features to be mapped, the first simulation model and the second simulation model may be one, and features of one first simulation model are mapped in one second simulation model. The number of the first simulation models can be multiple, the number of the second simulation models can be one, and the characteristics of the multiple different first simulation models are mapped on 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 set on the plural second simulation models.
Optionally, determining the mapping relationship between the product configuration and the plurality of different simulation models, respectively, includes: respectively determining a plurality of constituent units constituting a simulation model; and establishing a mapping relation between the constituent units and the parts of the product configuration.
The above-mentioned constituent units of the simulation model are not used in different simulation models, for example, in CAD systems, the minimum units of the simulation model are parts, for example, screws, some castings, etc., in CAE systems, the entire simulation model is divided into grids, and each part is specifically divided into grids according to a division rule. Therefore, it is necessary to determine the constituent elements of the simulation model first, and the constituent elements may be determined by dividing in units of parts of the product configuration.
Optionally, mapping the features of the first simulation model to 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 constituent units of the first simulation model to one part of the second simulation model; or, according to the mapping relation, the characteristics of the plurality of constituent units of the first simulation model are mapped onto the plurality of parts of the second simulation model.
The mapping the features of the first simulation model to the second simulation model comprises mapping the features of the first simulation model to the database for storage according to the product configuration and the mapping relation, and then mapping the features in the database to the second simulation model according to the product configuration and the mapping relation. Specifically, the feature may be attribute information, and mapping the feature of the first simulation model to the second simulation model according to the mapping relationship includes: acquiring attribute information of a first composition unit of the first simulation model according to a first mapping relation between the first simulation model and the product configuration; storing attribute information of the first constituent 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, storing the attribute information of the first constituent unit according to the product configuration includes: determining a storage data structure of a plurality of attribute information according to a hierarchical structure of the product configuration; and storing the plurality of attribute information according to a storage data structure.
Optionally, the attribute information includes at least one of the following: material information, size information, load information, constraint information.
Different simulation models have different attribute information, and in different simulation models, simulation environments are different, set parameters are different, and specific attribute information is also different. The material information includes the material quality of the parts, the material arrangement ratio, and the physical parameters of the materials, such as hardness, density, quality, etc. The size information includes distance, thickness, radian, length and the like with 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 constraint, fixed constraint, etc.
Before the features of the first simulation model are mapped onto the second simulation model according to the mapping relation, the method further comprises: and receiving a mapping instruction, wherein the mapping instruction is used for indicating that the features of the first simulation model are mapped onto the second simulation model.
The mapping instruction is sent by a user or triggered by a software mapping condition. The description needs to be mapped in this case. The timeliness of mapping is effectively improved, and therefore the mapping efficiency is improved.
Optionally, the features 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 features, the product configuration of the first simulation model also has features, the features of the first simulation model are taken as first features, and the features of the product configuration of the first simulation model are taken as second features. 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, so that the mapping efficiency is improved.

No analysis or calculation was made in the product configuration. Its configuration remains substantially unchanged during the different stages of development of the product. The model configuration is provided with units, configurations, loads, analyses and results. CAD and CAE correlation analysis can be performed in the model configuration.
