Abstract
Description
Technical Field
[0001] The present invention relates to the field of mechanical design and manufacturing, and in particular to an MBD three-dimensional control model interface management method and system. Background Art
[0002] In the field of traditional mechanical design and manufacturing, the information transmission of industrial products is extremely dependent on two-dimensional drawings. From the initial hand-drawn drawings to the two-dimensional models of computer-aided design (CAD), and then to the two-dimensional drawings generated by the projection of three-dimensional solid models, although breakthroughs have been made in design methods and design tools, there has been no substantial change in the final information transmission method, which is only the computerized application of hand-drawn two-dimensional drawings. Traditional two-dimensional drawings contain information such as product dimensions, tolerance requirements, material selection, and process requirements. The transmission of this information requires designers to have strong three-dimensional spatial imagination capabilities. In addition, in the process of transmitting product information to downstream, differences in drawing reading capabilities can easily lead to inaccurate information transmission, which will cause unnecessary design iterations in the design process and will cause product out-of-tolerance scrapping in the manufacturing process. The more complex the product spatial structure, the more likely it is to cause this phenomenon.
[0003] In order to solve the problem of insufficient definition of two-dimensional drawings, the three-dimensional design mode has been basically realized in the field of aircraft engine design. In recent years, the Model Based Definition (MBD) method has been introduced to completely replace two-dimensional engineering drawings. MBD is an advanced method for digital definition of products. It means that all kinds of information defined by products are organized in a modeled, structured and integrated manner. Its core content is the geometric model of the product. All relevant dimensional tolerances, technical requirements, materials and standards and other related management information are attached to the three-dimensional model of the product. The MBD method based on the three-dimensional geometric model can intuitively express the information and non-geometric information of the product, and can realize the information transmission between product components and parts, and between parts through the associative modeling function of the modeling software. This design process can minimize unnecessary design iterations and help improve work efficiency.
[0004] MBD method can be used not only for product manufacturing information transmission, but also for interface information transmission between product components and parts or between parts. This model that uses MBD method to control the interface of components is called MBD three-dimensional control model. Thanks to the associative modeling function of modeling software and the efficient and accurate product information expression method of MBD, MBD three-dimensional control model can completely replace traditional two-dimensional interface drawings and realize the interface control of product components. However, the existing MBD three-dimensional control model is often for a single interface, using the product geometry model to complete the interface information transmission and control through the MBD method. This control model will combine the geometric features of the product interface with the non-geometric feature information, and does not group the structural features of the product interface. It is difficult to modify the interface for a single feature, which is not conducive to the design iteration work. In addition, the existing MBD three-dimensional control model is difficult to realize large-scale, multi-feature, multi-category, and multi-quantity interface control, and the subsequent maintenance and management operations are very complicated and inefficient. At present, there is a lack of efficient MBD three-dimensional control model interface management method to realize large-scale, multi-feature, multi-category, and multi-quantity interface control.

[0042] The present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments. Note that the aspects described below in conjunction with the accompanying drawings and specific embodiments are only exemplary and should not be construed as limiting the scope of protection of the present invention in any way.
[0043] Disclosed herein is an embodiment of a method for managing an MBD three-dimensional control model interface. Figure 1 This is a flow chart showing an embodiment of the MBD three-dimensional control model interface management method of the present invention. Figure 1 ,The following is a detailed description of each step of the MBD three-dimensional control model interface management method.
[0044] Step S1: Collect various types of product interfaces according to product interface definitions.
[0045] In this embodiment, in order to effectively realize the large-scale, multi-feature, multi-category, and large-quantity interface management and control in the MBD three-dimensional control model of the product, various types of product interfaces are collected in advance according to the product interface definition, and these interfaces are grouped according to different characteristics and categories. Each group of interfaces is independently managed and controlled, thereby realizing the management of the interfaces in the MBD three-dimensional control model.
[0046] Step S2: Classify the collected product interfaces and establish interface categories.
[0047] In this embodiment, the product interface includes a component-component interface, a component-part interface, and a part-part interface. After identifying all the component-component interfaces, component-part interfaces, and part-part interfaces in the product, these product interfaces are classified according to the functional requirements or other requirements of each interface, thereby establishing multiple interface categories.
[0048] Specifically, in this embodiment, since the MBD three-dimensional control model of the product contains a large number of component interfaces, after identifying all the interfaces between components, components and parts, and parts and parts in the product, it is necessary to classify these product interfaces according to the functional requirements or other requirements of each interface, thereby realizing the splitting and grouping of the interfaces in the MBD three-dimensional control model. Among them, the interfaces in the MBD three-dimensional control model are divided into physical interfaces and technical requirements. For physical interfaces, they include flange position, bolt position, number of bolts, welding position, flow channel profile, sealing surface, etc. The technical requirements include roughness, dimensional tolerance, geometric tolerance, tightening torque, special process requirements, performance test requirements, etc. According to the functional requirements or other requirements of these interfaces, the physical interfaces and technical requirements of the product are divided to obtain multiple integrated unit bodies based on interfaces, and these integrated unit bodies are interface categories.
[0049] Step S3: construct corresponding interface feature groups for each interface category according to the interface features.
[0050] In this embodiment, after completing the classification of the product interfaces through the above step S2, corresponding interface feature groups are constructed for each interface category according to the interface features. The interface particularly includes the geometric features and local features of the product interface. When grouping the product interfaces, the interface features of each product interface are defined according to the geometric features and local features of the product interface, and then the interface features belonging to the same interface category are grouped according to the interface category, thereby obtaining the interface feature groups of each interface category.

Among them, multiple interface feature groups can be defined for a single interface category. For example, for interface Ki, interface feature groups a1, a2, ..., an are created. These interface feature groups express the local features or geometric features of the corresponding interface categories. When modifying and iterating the MBD three-dimensional control model, the modification and iteration of the corresponding interface can be completed by modifying the interface feature group corresponding to the interface category, thereby improving the model update iteration efficiency.
[0052] Step S4: construct and manage interfaces in the product MBD three-dimensional control model based on the interface categories and corresponding interface feature groups.
[0053] In this embodiment, after the interface category of the product and the corresponding interface feature group are designed through the above steps, each interface in the MBD three-dimensional control model is constructed according to the interface category of the product, and each interface in the MBD three-dimensional control model is managed according to the interface feature group corresponding to each interface.

[0056] Step S43: Merge the interface feature groups to obtain the interface feature group subset of the interface.
[0057] In this embodiment, when creating an interface in a product MBD three-dimensional control model, it is first necessary to identify the geometric features and local features of the interface, and then group the identified geometric features and local features with reference to the interface category and the corresponding interface feature group corresponding to the interface, thereby obtaining multiple interface feature groups of the interface. For a single interface, its interface feature groups need to be merged to obtain an interface feature group subset of the interface.
[0058] Step S44: Create and manage corresponding interfaces in the three-dimensional control model according to the interface categories and interface feature group subsets corresponding to the interfaces.
[0059] In this embodiment, after the interface feature group subset of the interface is obtained through the above steps, the corresponding interface in the MBD three-dimensional control model is created according to the interface category and the interface feature group subset corresponding to the interface. Thus, referring to the above steps, the creation of all product interfaces in the MBD three-dimensional control model is completed in sequence. Through this method, all interfaces in the MBD three-dimensional control model are classified and managed according to the interface feature group, the interface to be changed can be quickly located, and the interface information can be conveniently and efficiently viewed and transmitted, which is convenient for the later maintenance and management of the model, and is conducive to improving the efficiency of the design work. Moreover, for a single interface, the present invention can modify its local features based on the interface feature group expression corresponding to its interface category, thereby improving the efficiency of design iteration.

[0064] In this embodiment, after the product interfaces are classified by the interface category construction unit, the interface feature group construction unit constructs corresponding interface feature groups for each interface category according to the interface features. The interface particularly includes the geometric features and local features of the product interface. When grouping the product interfaces, the interface features of each product interface are defined according to the geometric features and local features of the product interface, and then the interface features belonging to the same interface category are grouped according to the interface category, thereby obtaining the interface feature groups of each interface category.

These interface feature groups express the local features or geometric features of the corresponding interface categories. When modifying and iterating the MBD three-dimensional control model, the modification and iteration of the corresponding interface can be completed by modifying the interface feature group corresponding to the interface category, thereby improving the model update iteration efficiency.
