[0033] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0034] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.
[0035] The aircraft rivet array layout detection method provided in the embodiment of the present application can be applied to Figure 1 In the application environment shown. Among them, the terminal 102 communicates with the server 104 through the network. The data storage system can store the data that the server 104 needs to process. The data storage system can be set up separately, integrated on the server 104, or placed on the cloud or other servers. The terminal 102 can send the aircraft product model to the server 104. After the server 104 receives the aircraft product model, for the aircraft product model, the server 104 defines the components of the aircraft product model to obtain the MBD rivet inspection model. According to the inspection standard of the aircraft rivet array layout, the aircraft components in the MBD rivet inspection model are divided to obtain machined parts, sheet metal parts, standard parts and assembly information. The interface function of the CATIA system is used to obtain the rivet array-related components from the MBD rivet inspection model, and the aircraft rivet array layout is inspected according to the inspection rule base and the rivet array-related components to obtain the inspection results. The server 104 can feedback the obtained inspection results to the terminal 102. In addition, in some embodiments, the aircraft rivet array layout detection method can also be implemented independently by the server 104 or the terminal 102. For example, the terminal 102 can directly perform the aircraft rivet array layout detection on the aircraft product model, or the server 104 can obtain the aircraft product model from the data storage system and perform the aircraft rivet array layout detection on the aircraft product model.
[0036] The terminal 102 may be, but is not limited to, various desktop computers, laptop computers, smart phones, and tablet computers. The server 104 may be implemented as an independent server or a server cluster consisting of multiple servers, or may be a cloud server.
[0037] In an exemplary embodiment, Figure 2 and Figure 7 As shown, a method for detecting the layout of an aircraft rivet array is provided. The method is executed by a computer device, and specifically can be executed by a computer device such as a terminal or a server alone, or can be executed by a terminal and a server together. In the embodiment of the present application, the method is applied to Figure 1 The server 104 in the example is used as an example to illustrate, including the following steps 201 to 205. Among them:
[0038] Step 201: Using the CAA (Component Application Architecture) tool of the CATIA system, define the components of the aircraft product model to obtain an MBD (Model Based Definition) rivet inspection model.
[0039] Step 202: According to the inspection standard of the aircraft rivet array layout, the aircraft components in the MBD rivet inspection model are divided to obtain machined parts, sheet metal parts, standard parts and assembly information; the assembly information includes rivet array information.
[0040] Step 203: using the interface function of the CATIA system, obtaining rivet array-related components from the MBD rivet inspection model.
[0041] Step 204: Establish an inspection rule base based on assembly standards and inspection standards of aircraft components.
[0042] Step 205: Inspect the aircraft rivet array layout according to the inspection rule base and the rivet array associated components to obtain an inspection result.
[0043] Implement the above steps 201 to 205, define the components of the aircraft product model, obtain the MBD rivet inspection model, divide the aircraft components in the MBD rivet inspection model according to the inspection standard of the aircraft rivet array layout, obtain machined parts, sheet metal parts, standard parts and assembly information, use the interface function of the CATIA system to obtain the rivet array associated components from the MBD rivet inspection model, inspect the aircraft rivet array layout according to the inspection rule library and the rivet array associated components, and obtain the inspection results, which solves the problem of high efficiency and low cost of manual inspection methods, realizes digital inspection of the rationality of rivet array layout, improves the inspection efficiency of aircraft rivet array layout, and reduces the inspection cost. In addition, compared with the traditional, manually guaranteed inspection method, the present application has a significant effect in improving inspection efficiency and cost control. In addition, compared with manual inspection, digital inspection is more guaranteed in comprehensiveness and accuracy. When obtaining the associated components of the rivet array, the means of cross-calculation of the topological level and the geometric level are adopted, which actually realizes the process from visual "association" to actual acquisition of associated components. This process previously had a certain degree of subjectivity. This application simplifies the tedious process of manual definition and finding related components while removing the influence of subjectivity. In addition, the semantic interception used in this application can reversely guarantee the standardization of naming in the MBD model. The establishment process of various rule bases and reasoning systems can directly implement the text content in the inspection standard into the inspection process, eliminating the manual processing process.
[0044] With the popularization of digitalization in the aviation field, traditional inspection methods are gradually replaced by digital means. In the CATIAV5 environment, this application uses CATIA's secondary development tool (CAA tool for secondary development). For the pre-processed rivet array, this application first defines the type of components to be inspected based on the MBD rivet inspection model and conventional inspection standards. Then, based on the topological information of the model, the associated components of different types of rivets are screened out. Then, a rule base is established based on production, manufacturing and inspection standards, and a rule-based reasoning system is formed based on the rule base. Finally, the MBD model is inspected in accordance with the rule base. For unreasonable rivet array layouts, the problem points are quickly located, and solutions are recommended based on rules according to different problem types. The inspection list is submitted to the inspectors to form an inspection list, and the rationality of the predefined rivet array layout during the aircraft assembly process is inspected. Since the traditional inspection method does not emphasize the association with the MBD model, a large part of the relevant inspection standards is still formulated for physical products, and there is huge room for optimization in terms of efficiency and economy. This application is oriented to the MBD model, and the requirements of assembly, inspection standards and various rule files are concretized to form a reasoning system for the rationality inspection of rivet array layout. It can significantly improve the efficiency and accuracy of inspections and reduce inspection costs. In addition, it can reduce manual intervention, realize the digitization of related inspection processes, and greatly shorten the process time from starting inspections, generating inspection reports, to optimizing rivet arrays, and re-inspecting. In addition, the MBD model is used to quickly locate problems, and intelligent recommendations can be made based on standards for dimensional and tolerance issues, greatly improving the efficiency of the problem correction stage. In addition, the inspection process proposed in this application is unified with the digital assembly process of the aircraft, which helps promote the digitization of the rationality inspection of the predefined rivet array layout.
[0045] CAA provides a large number of interfaces for obtaining MBD model information and for operating various hierarchical elements, including document level (such as CATIDocument), product level (such as CATIProduct), topology level (such as CATCell), geometry level (such as CATPoint), etc. In addition, it also provides a large number of interfaces (such as CATISpecObject) for operating the node information of the structure tree. This application is implemented by obtaining these interfaces or defining new interfaces.
[0046] In another exemplary embodiment of the present application, the process of defining the type of components to be inspected based on the MBD model and the inspection standard is as follows: Figure 3 As shown, step 201 needs to define the imported model according to the requirements of MBD so that the model can actually operate under the "rivet array layout inspection" function module.
[0047] Then the above step 202 is replaced by the following steps 301 to 302:
[0048] Step 301: extract key information from the inspection standard of the aircraft rivet array layout to obtain key fields of the components;
[0049] Step 302: Divide the aircraft components in the MBD rivet inspection model according to the component key fields to obtain machined parts, sheet metal parts, standard parts and assembly information.
[0050] According to the inspection standards provided by the enterprise, all parts in the MBD model are divided into four types: machined parts, sheet metal parts, standard parts and assembly information. The assembly information contains all the rivet array information of the MBD model (the rivet array information includes rivet model, quantity and position, etc.). Through the object property management interface (CATISpecObject), geometric graphics set interface (CATIMmiNonOrderedGeometricalSet), etc., the geometric graphics set under each component node is obtained layer by layer. Furthermore, the key information in the paragraph is extracted for division, and the member functions in the specific string type (CATUnicodeString) are flexibly used for auxiliary implementation.
[0051] Get the current document, which is determined by the assembly standard and inspection standard of aircraft parts. Then get the product node, extract the key information of the product name, and determine whether it is a standard part based on the key information of the product name. If so, define it as a standard part. If not, determine whether it is assembly information. If so, define it as assembly information. If not, get the product instance, read the geometry set interface, determine whether the sheet metal parameters are defined, if so, define it as a sheet metal part, if not, define it as a machined part, and visualize and edit the data.
[0052] It should be noted that in the CATIA assembly environment, product types include reference and instance. Among them, reference products are at a higher level. Under each reference product, there may be multiple instance products, and these instance products may be obtained by copying the same instance product. Different reference products are named differently, while under the same reference product, the first half of the name of different instance products is exactly the same, and sequential numbers are used to distinguish different instance products. Reference products contain reference attributes and common attributes of all instances under them, while instance products only contain their own attributes.
[0053] In another exemplary embodiment of the present application, in the MBD model provided by the enterprise, the rivet array information is defined separately in the assembly information, and is not directly associated with other components, so the associated information cannot be directly read through the model. Therefore, this step is based on the relative position information between the components, and through the cross operation between the feature tree and the elements at different levels, the associated components of different models of rivets are obtained. The definition of the rivet associated components is as follows: Figure 4 The process of obtaining the associated parts of the rivet array is as follows: Figure 5 As shown, the above step 203 is replaced by the following steps 401 to 405:
[0054] Step 401: using the interface function of the CATIA system to obtain a face set of the assembly information component;
[0055] Step 402: Establishing a correspondence between geometric faces in the face set and aircraft components, and obtaining a geometric face corresponding to each aircraft component;
[0056] Step 403: establishing a plurality of rivet array sets according to the models of all rivets;
[0057] Step 404: for each rivet array set, obtain the intersection surface corresponding to each rivet according to the entity of the rivet in the rivet array set; the intersection surface is the intersection surface where the rivet collides with the MBD rivet inspection model;
[0058] Step 405: Determine the associated components of the rivet according to the intersection surface corresponding to the rivet, and the associated components of all rivets in the rivet array set constitute the rivet array associated components.
[0059] The specific process of step 401 is as follows: Model parsing first obtains interfaces such as CATIPrtPart and CATIMechanicalTool at the assembly level and enters the mechanical product level layer by layer. Further, obtain interfaces such as CATCell at the topological level, and enter the geometric level by designing functions and calling member functions. The specific process of step 402 is as follows: At the geometric level, obtain the face set of all parts through interfaces such as CATBody and CATFace. Then, use interfaces such as CATIAlias to establish a corresponding relationship between faces and parts, and store them in the form of key-value pairs for easy reading.
[0060] Step 403 is specifically as follows: according to the assembly information component obtained in step 401, the geometric graphics set interface and the line interface (CATIGSMLinePtDir) defined in the form of point-direction are combined to realize the acquisition and classification storage of rivet sets of different models, and obtain several rivet array sets. Subsequently, the rivet entities defined in the form of lines and center circles and the surface information of each component are obtained through the topological level interface.
[0061] The process of obtaining the rivet entity and determining whether it collides with the model is as follows: Figure 6 As shown, firstly, through the CATIGSMLinePtDir interface, the design function obtains the starting and ending points and direction vectors of the rivet, and accordingly establishes the line used for judgment to form the judgment intersection line. Then, the geometric faces in the face set formed after the model parsing obtained in step 402 are traversed to determine whether interference occurs, that is, the interfaces such as CATIntersectionCrvSur and CATCartesianPoint are used to try to create intersection points. If interference occurs, the component corresponding to the interference surface is obtained through the element name operation interface (CATIAlias), and it is determined whether the interference point is located on the surface of the component corresponding to the interference surface. If the interference point is located on the surface of the component corresponding to the interference surface, the association relationship between the rivet and the component corresponding to the interference surface is established and stored. If the interference point is not located on the surface of the component corresponding to the interference surface, it is determined whether there are still geometric faces that have not been judged. If there are geometric faces that have not been judged, return to the step of "traversing the geometric faces in the face set formed after the model parsing obtained in step 402". If there are no geometric faces that have not been judged, the rivet has no associated parts. If the intersection is successfully obtained, the CATVolume, CATPositionPtVolOperator and other interfaces are used to determine whether the intersection is located on the surface (geometric surface) of each component. After the judgment is established, the interference information of the line and the surface is stored in a classified manner. After the rivet entity is matched with the interfering surface, the element name operation interface is used to trace back to the product level of each component. Through the mutual conversion between the reference product and the instance product, the acquisition of the associated components of the rivet array is achieved while ensuring the uniqueness of the instance product name.
[0062] After successfully obtaining the associated components of all rivet arrays, a rule-based reasoning system is established for different rivet types and types of components to be inspected. First, an inspection rule base is established based on production, manufacturing and inspection standards. The establishment of the rule base fully considers the differences in inspection standards between different rivet types and different component types, and realizes the classification, hierarchical storage and visual display (CAT3DViewer) of standard items. Further, based on the generated rule base, the problem model is established in sections in combination with the actual situation, and corresponding solutions are provided for different types of problem models. For inspection items involving the compliance of the relative positions of rivet arrays and associated components, the boundaries of the associated components are first obtained according to the bounding box system of the topological level, and then the cross-calculation scheme of the topological level and the geometric level is designed for inspection in combination with the position information of the rivet array. For abstract inspection items (such as surface scratches, hole edge burrs, etc.), the list editing control (CATDlgMultiList) is called to generate editable inspection entries for subsequent use by inspectors.
[0063] After obtaining the inspection results, the aircraft rivet array layout inspection method further includes:
[0064] When the inspection result is position deviation, the components corresponding to the position deviation are displayed;
[0065] When the inspection result is a dimensional tolerance deviation, the dimension, tolerance documents and inspection standards are used for comparison, and recommendations are made for non-compliant dimensions and tolerances.
[0066] For non-compliant rivet arrays detected, solutions are recommended based on rules. For position deviation problems, a visual interface (CAT3DBagRep, etc.) is used to highlight the problem area, allowing inspectors to quickly locate the problem point. Then, solutions are recommended based on rules to guide inspectors to generate inspection reports and guide technical personnel to make corrections. For dimensional tolerance problems, dimension and tolerance files (including GB, GJB, HB, etc.) and inspection standards are used for comparison, and intelligent recommendations are made for non-compliant dimensions and tolerances. For abstract inspection items that cannot be directly inspected in the MBD rivet inspection model, fields to be inspected will be generated and exported to the information management system for further inspection.

Specifically, in the aircraft rivet array layout detection link process for the aircraft product model, the MBD rivet inspection model can be obtained by defining the components of the aircraft product model, and the aircraft components in the MBD rivet inspection model can be divided according to the inspection standard of the aircraft rivet array layout to obtain machined parts, sheet metal parts, standard parts and assembly information. The interface function of the CATIA system is used to obtain the rivet array-related components from the MBD rivet inspection model, and the aircraft rivet array layout is inspected according to the inspection rule base and the rivet array-related components to obtain the inspection results.
