The embodiment of the invention provides an automatic modeling method for an opening and closing member, and referring to fig. 2, fig. 2 is a schematic flow chart of a first embodiment of the automatic modeling method for an opening and closing member.
In this embodiment, the automatic modeling method for the opening and closing member includes the following steps:
Step S10: and acquiring the original data of the opening and closing part, and carrying out hierarchical processing on the original data of the opening and closing part to acquire a hierarchical file.
It should be noted that, the execution body of the embodiment may be a computing service device with functions of data processing, network communication and program running, such as a tablet computer, a personal computer, an upper computer, or an electronic device or an intelligent television capable of implementing the above functions. This embodiment and the following embodiments will be described below with reference to the computer.
It will be appreciated that the shutter data used in this embodiment is in the Catia format, and that the Catia interactive CAD/CAE/CAM system is a product development flagship solution from dasos, france. As an important component of PLM collaborative solutions, it can help manufacturers design their future products through modeling and support all industrial design flows from pre-project stages, specific design, analysis, simulation, assembly to maintenance.
In a specific implementation, the whole open-close part modeling flow is started by the hierarchical relation processing module and triggered and started by a user after a path of the open-close part Catia norm model, namely a working path, is given.
It should be noted that, in this embodiment, HYPERMESH (hereinafter abbreviated as Hm) is used as a scenario of finite element preprocessing software, HYPERMESH software is a product of Altair corporation in usa, is a world-leading, powerful CAE application software package, and is also an innovative, open enterprise-level CAE platform, which integrates various tools required for design and analysis, and has unparalleled performance and a high degree of openness, flexibility, and friendliness.
It is understood that the vehicle opening and closing member includes a vehicle body member that can be opened and closed, and the opening and closing member has a wide range. The opening and closing member is integrated with a body hinge and other various accessories such as an engine cover, a sunroof of a vehicle body, a door, and a trunk lid as a whole. In an automobile system, the opening and closing member constitutes an essential part thereof, and the performance of the opening and closing member itself is related to the running stability of the whole automobile.
The hierarchical processing refers to processing only the packet and the table corresponding to the data without paying attention to other information in the process of processing the data.
In a specific implementation, acquiring the original data of the opening and closing member, performing level processing on the original data of the opening and closing member, and acquiring the level file refers to that the execution main body of the embodiment imports the original data of the opening and closing member, analyzes the original data of the opening and closing member, does not pay attention to geometric information in the original data, and only performs the speed-opening processing on the level information to acquire the corresponding level file.
Further, in order to increase the speed of automatic modeling, the step of obtaining the original data of the opening and closing member, performing hierarchical processing on the original data of the opening and closing member, and obtaining a hierarchical file includes: acquiring original data of an opening and closing part, deleting geometric information and link information in the original data of the opening and closing part, and acquiring hierarchy information; and generating a hierarchy file according to the hierarchy information.
In specific implementation, acquiring opening and closing piece original data, deleting geometric information and link information in the opening and closing piece original data, and acquiring hierarchy information; generating the hierarchy file according to the hierarchy information means processing the original data of the opening and closing member, deleting all geometric information, deleting all connection related information, including the hierarchy information of all connections, so as to derive the hierarchy file.
It should be noted that, in this embodiment, when the original data is processed, the corresponding module serially outputs the execution function, that is, when one module performs the function, the other modules are in a waiting state.
Step S20: and carrying out grid processing on the original data of the opening and closing piece to obtain a grid file.
The grid processing refers to processing only specific components without paying attention to hierarchy and connection information.
It can be understood that the grid file refers to a grid file generated after the geometric data of the opening and closing member is processed by the grid, and the grid file is also a part where the component processing module performs grid batch processing on all middle surfaces and automatically places the batch processed grids on the middle surfaces.
In a specific implementation, grid processing is performed on the original data of the opening and closing part, and obtaining the grid file refers to obtaining the original data of the opening and closing part, and only geometric information, specifically parts in the information, is processed without paying attention to other information in the data.
Step S30: and performing geometric processing on the original data of the opening and closing part to obtain a connection file.
The geometric processing means an operation performed by processing only the welding points, adhesion, bolts, and welds in the data by ignoring other information.
Further, in order to improve modeling accuracy, the step of geometrically processing the original data of the opening and closing member to obtain a connection file includes: extracting connection target point information from the original data of the opening and closing piece, wherein the target connection point information comprises welding spot information, adhesive information, welding seam information and bolting information; and generating a connection file according to the connection target point information.
In the specific implementation, the connection information processing module processes the original geometry again, extracts welding spot information, adhesive information, welding seam information and bolt connection information, and adds corresponding marks in the group names of the parts.
It should be noted that, the function implementation of the connection information processing module is provided according to specifications based on CAD data of the passenger car, and the situation that original connection information is not in a hierarchical rule caused by human factors is avoided.
It will be appreciated that for an assm with a "WP" designation in the assm name, the connection information processing module processes that assm and its next level of assm and its Comp contained therein as connection information and records the current assm name (e.g., 112233_xxxx_wp); the connection information processing module continues to traverse all other sub-assemblies in the assemblies (112233_XXXX_WP) in the step S32, in the sub-assemblies, if the name of the sub-assemblies is provided with similar fields such as 'two-layer welding', 'three-layer welding', the sub-assemblies are identified as welding spots in the connection information, if the sub-assemblies hit the similar fields such as 'welding spots', the sub-assemblies are identified as welding spots in the connection information, and the adhesive and the bolts adopt the same identification mode; for the sub-assembly identified as the solder joint in S33 above, the connection information processing module creates a new Comp according to the number of solder joint layers, and names the Comp as 112233_xxxx_wp_2t_3t_4t …, and places all connection information in the sub-assembly in the Comp; for the welding line, the adhesive and the bolt connection, the same treatment mode as the welding point is adopted.
Step S40: and modeling according to the hierarchical file, the grid file and the connection file to generate a corresponding model.
In the implementation, after detecting the connection file, the hierarchical relation processing module simultaneously imports the connection file, the grid file and the hierarchical file, and places the grid file and the connection file in the original assembly hierarchy according to the grid Comp and the part number information in the name of the connection Comp; after the hierarchical relation processing module is completed, the completion state is transferred to the connection information processing module again; the hierarchical relation processing module automatically generates connection units according to the hierarchy based on the hierarchy where the connection files and the grids thereof are located, automatically creates the connection unit attributes and gives corresponding connection units.
In this process, the thicknesses of all the components are extracted together and automatically assigned to the attributes automatically generated for each component.
It can be understood that the connection information processing module sends the execution completion status to the hierarchical relationship processing module; after the hierarchical relation processing module receives the message from the connection information processing module, detecting that the grid file, the hierarchical file and the connection file are all generated and starting to execute; the hierarchical relation processing module simultaneously imports the grid file, the hierarchical file and the connection file, and the grid file, namely the connection file, is placed in the original hierarchy based on mutual comparison of the part number field in the name of the grid file Comp, the part number field in the name of the connection file Comp and the part number field in the name of the hierarchical file Assem: the hierarchical relation processing module sends an execution completion state to the connection information processing module, and the connection information processing module starts work again after receiving the message from the hierarchical relation processing module; the connection information processing module traverses Comp of all connection geometries, and for each connection, automatically creates connection units only for all components in the hierarchy, wherein for solder joint connection, entity units are automatically created, and solder joint attributes, namely materials, are automatically created at the same time; for the viscose unit, adopting the same treatment mode as that of the welding spot unit; for the weld joint and the bolt unit, the connection information processing module automatically processes the weld joint unit and the bolt unit into rigid connection based on automation consideration and reducing the loss of automation degree caused by artificial repair of the grid quality as much as possible.
Further, in order to improve modeling efficiency, the step of modeling according to the hierarchy file, the grid file and the connection file to generate a corresponding model includes: matching the hierarchical file with the grid file, and generating target hierarchical component information according to a matching result; and modeling according to the target level component information and the connection file to generate a corresponding model.
In a specific implementation, the implementation steps of this embodiment specifically include: importing geometry, deleting all geometry, deleting Assems of connection information, exporting hierarchy information, importing geometry, deleting all hierarchy and connection information, middle plane and grid batch processing, exporting grids, importing geometry, connection information extraction, deleting all hierarchy and mail, exporting connection information, importing grids, hierarchy information and connection information, rearranging the grids and connection information to the original hierarchy, generating connection units and giving unit attributes.
It should be noted that, in the working process, the core module performs four communications in total, that is, the hierarchical relationship processing module to the component processing module to the connection information processing module to the hierarchical relationship processing module to the connection information processing module.
In the specific implementation, the execution steps are packaged in four core modules in a function modularization mode, and through the mutual coordination of functions of each module, the integrated modeling from CAD data to finite elements of the passenger car opening and closing part is basically realized, the efficiency of finite element modeling is greatly improved, the time investment of personnel is effectively reduced, the efficiency is greatly improved, and the investment cost is greatly reduced.
According to the embodiment, the original data of the opening and closing part are obtained, and hierarchical processing is carried out on the original data of the opening and closing part to obtain a hierarchical file; performing grid processing on the original data of the opening and closing piece to obtain a grid file; performing geometric processing on the original data of the opening and closing part to obtain a connection file; modeling is carried out according to the level file, the grid file and the connection file to generate a corresponding model, the level file, the grid file and the connection file are obtained by independently processing the original data of the opening and closing part, modeling is carried out according to the generated level file, grid file and connection file, and irrelevant factors are removed because only information content corresponding to the generated file is focused in the processing process, so that modeling time of the opening and closing part is shortened, and modeling efficiency is improved.
Referring to fig. 3, fig. 3 is a flowchart illustrating a second embodiment of an automatic modeling method for an opening and closing member according to the present invention. Based on the first embodiment, in this embodiment, the step S20 includes:
Step S201: and carrying out grid processing on the original data of the opening and closing piece to obtain a middle file to be processed.
It should be noted that, after the component processing module detects the exported hierarchical file, the execution program is automatically started.
It will be appreciated that the component handling module again handles the original geometry, first deleting all hierarchical information and all connection information, leaving only Comp for all components.
In the specific implementation, the component processing module automatically extracts the middle surfaces of all the components, the thickness of the components is automatically calculated in the process, and simultaneously, the attribute is automatically established and the thickness is given to each extracted middle surface; the materials build the steel uniformly and impart all properties.
It should be noted that the component processing module performs grid batch processing on all middle planes, and automatically places the batch processed grids at Comp where the middle planes are located.
In a specific implementation, the component processing module finishes executing and exports the grid file, and after exporting the grid file, the working message is transferred to the next module.
Further, in order to rapidly perform grid processing, the step of performing grid processing on the opening and closing piece original data to obtain a middle file to be processed includes: deleting the level information and the connection information from the original data of the opening and closing part to obtain component information; and performing extraction surface processing on the component information of the part to obtain a corresponding medium surface file to be processed.
Step S202: and obtaining a grid file according to the middle-plane file to be processed.
Further, in order to assign the parameter information of the grid file, after the step of obtaining the grid file according to the to-be-processed middle plane file, the method further includes: acquiring part attributes and parameter specifications in the part element information; establishing an attribute table according to the part attribute; and importing the grid file into the attribute table, and assigning values to the grid file according to the parameter rule to obtain the assigned grid file.
In a specific implementation, the middle surfaces of all the components of the opening and closing piece are automatically extracted by the component processing module, and in the process, the thicknesses of all the components are extracted together and automatically endowed with the attribute automatically generated for each component.
When the component processing module performs the median plane extraction on each component, the volume V and the surface area S of the component are extracted at the same time, and the thickness t=v/S of the component is calculated according to a formula.
It will be appreciated that each time the component handling module completes extraction of a face in a component, a shell attribute is created that is synonymous therewith, and the automatically calculated thickness is assigned to that attribute.
In a specific implementation, the component processing module traverses all midplanes and performs grid batch processing and places the batch grid for each component midplane at the Comp where its original midplane is located.
The component processing module transmits the execution completion state to the connection information processing module, and after receiving the message from the component processing module, the connection information processing module detects that the grid file has been generated, and starts to perform connection information separation on the original CAD data of the opening and closing member.
In the embodiment, the intermediate file to be processed is obtained by carrying out grid processing on the original data of the opening and closing part; obtaining a grid file according to the middle-plane file to be processed, obtaining the middle-plane file to be processed by carrying out grid processing on the original data of the opening and closing part, obtaining the grid file according to the middle-plane file to be processed, deleting the level information and the connection information from the original data of the opening and closing part, and obtaining the element information of the part; and performing extraction surface processing on the component element information to obtain a corresponding middle surface file to be processed, omitting other elements in the original data of the opening and closing part, and further improving the modeling efficiency.
