[0041] The disclosed embodiment provides a locomotive data evolution method based on full three-dimensional design, such as Figure 1 As shown, the evolution method may include steps S110 to S150, wherein:
[0042] Step S110, establishing a preliminary model of the whole vehicle in the scheme design module, and verifying a first performance parameter of the preliminary model of the whole vehicle; the preliminary model of the whole vehicle includes a reference skeleton of the whole vehicle design and a plurality of subsystem structures, and coordination interfaces are provided between different subsystem structures;

At the same time, in the above process, by designing the coordination interface step by step, the coordination interface between each component is gradually refined in the design of different levels, and the matching degree of each coordination interface is relatively high. In addition, by integrating the model with manufacturing information and using the three-dimensional annotation model as a bridge for information transmission, seamless connection and efficient collaboration between design and manufacturing and process are achieved, and the efficiency and quality of the entire product development and production process are improved.
[0048] The following is a detailed description of each step and specific details of the locomotive data evolution based on full three-dimensional design in the embodiment of the present disclosure:
[0049] like Figure 1 As shown, in step S110, a preliminary model of the whole vehicle is established in the scheme design module, and the first performance parameter of the preliminary model of the whole vehicle is verified; the preliminary model of the whole vehicle includes a whole vehicle design benchmark skeleton and multiple subsystem structures, and coordination interfaces are provided between adjacent subsystem structures.
[0050] Scheme design is the pre-stage of product technical design. The main purpose of scheme design is to determine the layout of the whole machine and the interface relationship between the systems. Figure 2As shown, the whole vehicle layout diagram, whole vehicle key parameters, technical specifications, etc. can be input into the scheme design module, and then the whole vehicle design basic skeleton and multiple subsystem structures can be constructed according to the whole vehicle layout diagram, whole vehicle key parameters, technical specifications and other documents. The reuse and variation of the three-dimensional digital module and the interface coordination between modules can be used for reference to quickly generate a three-dimensional digital prototype model of the scheme, and the mass centroid attributes of each system can be assigned. The three-dimensional digital prototype model with the mass centroid attributes of each system assigned can be used as the preliminary model of the whole vehicle.
[0051] In the present disclosure, a preliminary simulation analysis demonstration can also be developed based on the preliminary model of the whole vehicle (i.e., the three-dimensional digital prototype model), and the scheme can be adjusted according to the simulation analysis demonstration results until the simulation analysis demonstration results meet the set first preset standard. In the scheme design stage, the preliminary model of the whole vehicle can also be reviewed, and revised and confirmed according to the review results, and then the three-dimensional coordination interface model between the overall layout and the subsystem structure can be output. The overall layout and the three-dimensional coordination interface model can be used as the main input requirements of the technical design module in the technical design stage.
[0052] In some embodiments of the present disclosure, the subsystem structure of the present disclosure may include a body system, a bogie system, an electrical system, a power and transmission system, a braking system, a microcomputer network control system, etc. Of course, it may also include other systems in the whole machine, which are not listed one by one here.
[0053] In an exemplary embodiment of the present disclosure, after the preliminary model of the whole vehicle is established and before the review, the first performance parameter of the preliminary model of the whole vehicle may be verified to determine whether the preliminary model of the whole vehicle meets the corresponding performance requirements.
[0054] In an exemplary embodiment of the present disclosure, establishing a preliminary model of the whole vehicle in the scheme design module and verifying the first performance parameter of the preliminary model of the whole vehicle (i.e., step S110) may include steps S210 to S230, wherein:
[0055] Step S210, constructing a vehicle design reference framework in the scheme design module according to the technical specifications, key vehicle parameters and vehicle layout diagram.
[0056] The key parameters of the vehicle may include at least two of the reference coordinate system, vehicle body geometry, dimensions of each part of the vehicle body geometry, wheelbase, track width, coupler center distance, height of coupler center line from rail surface, chassis length, vehicle body width, vehicle body height, bogie center distance, fixed wheelbase, locomotive curb weight, locomotive axle weight, suspension system type and center of gravity position. The vehicle parameters can be structured and defined according to the technical specifications, key vehicle parameters and vehicle layout diagram, and the vehicle design reference skeleton can be created.
[0057] Step S220, selecting a three-dimensional annotation model corresponding to each subsystem structure in the solution model library according to the key parameters of the whole vehicle, and placing the three-dimensional annotation model at a preset position in the whole vehicle design reference skeleton.
[0058] The solution model library can be a storage database for various 3D annotation models designed in the data evolution process of other locomotives before this design, including the 3D annotation models corresponding to the subsystem structures designed before this design. The 3D annotation models corresponding to the subsystem structures can be selected from the solution model library according to the key parameters of the whole vehicle, and the selected 3D annotation models can be placed in the preset positions corresponding to the subsystem structures in the design benchmark skeleton of the whole vehicle, thereby realizing the rapid layout of the whole vehicle.
[0059] In an exemplary embodiment of the present disclosure, when the solution model library does not include a three-dimensional annotation model corresponding to a subsystem structure, a three-dimensional annotation model corresponding to the subsystem structure can be constructed according to the key parameters of the whole vehicle, and the three-dimensional annotation model corresponding to the subsystem structure constructed according to the key parameters of the whole vehicle is added to the solution model library, and then the three-dimensional annotation model corresponding to the corresponding subsystem structure is selected from the solution model library.
[0060] It should be noted that different subsystem structures may require different key parameters. Taking the construction of the bogie model as an example, the bogie system model can be constructed based on key parameters such as the bogie's geometric dimensions, the diameter, width and spacing of the wheelset, material parameters, the connection and constraints between components, dynamic and kinematic parameters, load and boundary condition parameters, and the performance parameters of the bogie. Taking the construction of the brake system model as an example, the brake system model can be constructed based on key parameters such as brake cylinder pressure, braking distance, braking time, braking torque, friction coefficient between wheels and rails, response time of the brake system, materials and wear of brake discs / shoes, and types and properties of brake fluids.
[0061] After placing the 3D annotated model at a preset position in the vehicle design benchmark skeleton, it is possible to determine which systems need to communicate with each other based on the interaction requirements and data flows between the systems. After determining the systems that need to communicate, detailed specifications can be developed for the systems, which may include physical connections, data formats, communication protocols, etc. Subsequently, each interface can be designed in detail based on the interface specifications.
[0062] In some embodiments of the present disclosure, after the coordination interface is formed, the weight of each subsystem structure can also be distributed to ensure the center of gravity of the entire vehicle design model, which helps to ensure the safety of the vehicle.
[0063] Step S230, simulating the preliminary model of the whole vehicle and verifying whether a first performance parameter of the preliminary model of the whole vehicle meets a first preset standard, wherein the first performance parameter includes at least one of the driver's cab field of view, strength, heat dissipation performance, maintainability and ventilation.
[0064] The first preset standard may include a plurality of evaluation standards, that is, each type of the first performance parameter is provided with an evaluation standard corresponding to the first performance parameter.
[0065] After the preliminary model of the whole vehicle is built, various types of simulations can be performed on the preliminary model of the whole vehicle to detect whether the various performance parameters of the preliminary model of the whole vehicle meet the first preset standard, thereby verifying the feasibility of the preliminary model of the whole vehicle. For example, the preliminary model of the whole vehicle can be simulated by simulation software for the driver's cab field of view, dynamic performance, strength, heat dissipation performance, maintainability and ventilation, etc. When each parameter meets the corresponding evaluation standard, the preliminary model of the whole vehicle is judged to be successfully built; if any of the parameters does not meet the corresponding evaluation standard, the preliminary model of the whole vehicle is judged to have failed to build, and it is necessary to rebuild the preliminary model of the whole vehicle or adjust the key parameters of the benchmark skeleton or subsystem structure.
[0066] like Figure 1 As shown, in step S120, when the first performance parameter corresponding to the preliminary model of the whole vehicle meets the first preset standard, the preliminary model of the whole vehicle is transmitted to the technical design module, and the technical design module partitions each of the subsystem structures to form a plurality of sub-areas; a sub-model is formed in each of the sub-areas and a coordination interface between the sub-models is formed.
[0067] When each parameter in the first performance parameter corresponding to the initial model of the whole vehicle meets the corresponding evaluation criteria, the design link of each subsystem structure can be carried out through the scheme design module. For example, the technical design module is based on the preliminary model of the whole vehicle formed by the scheme design module, and divides the subsystem structure in the preliminary model of the whole vehicle into multiple sub-areas; each sub-area is designed in detail to form a sub-model and a coordination interface between each sub-model. The technical design module mainly includes 3D collaborative design software and data management platform, which mainly relies on 3D collaborative design software and data management platform for online collaborative design.
[0068] For example, the zero-point coordinates of the initial model of the whole vehicle can be used as the reference to define the installation reference coordinate system of each subsystem structure, and then determine the position skeleton of each subsystem structure on the initial model of the whole vehicle; then create the main skeleton of each subsystem structure and the submodels contained in each subsystem structure, as well as the coordination interface between different submodels. After each submodel is established, the second performance parameter of the subsystem model composed of the submodels can also be verified to determine whether the subsystem structure model composed of each submodel meets the corresponding performance requirements.
[0069] In an exemplary embodiment of the present disclosure, when the first performance parameter corresponding to the preliminary model of the whole vehicle meets the first preset standard, the preliminary model of the whole vehicle is transmitted to the technical design module, and the technical design module partitions each subsystem structure to form a plurality of sub-areas; and a sub-model is formed in each sub-area and a coordination interface between each sub-model (i.e., step S120) may include steps S310 to S340, wherein:
[0070] Step S310, creating a top-level structure of a model product.
[0071] The technical specification and demand tracking matrix can be input into the product lifecycle management (PLM) system platform, and the early top-level BOM structure can be built through the PLM system platform, and the early top-level BOM structure can be synchronized to the 3D collaborative design software to generate the design BOM structure. It should be noted that the BOM structure is mainly composed of two parts: materials and quantities, and structural relationships (assembly relationships), among which: materials and quantities clearly list all sub-models and raw materials required for the product, as well as their quantities. This is the basic data of the BOM structure and directly reflects the material requirements of the product. The structural relationship describes the assembly relationship between sub-models and raw materials, that is, how they are assembled into the final product. This relationship is usually expressed in the form of a parent-child relationship, where the parent item is the upper layer of material in the assembly process and the child item is the material to be assembled in the next layer.
[0072] Step S320, constructing a sub-model in the subsystem structure, and matching the sub-model to a preset position on the main body skeleton.
[0073] The preliminary model of the whole vehicle constructed by the scheme design module can be introduced as the interface model of the technical design module. In the 3D collaborative design software, the preliminary model of the whole vehicle in the scheme design stage can be introduced as the interface model in the technical design stage, and a sub-model (i.e., the first-level subsystem node structure model) can be constructed according to the technical specification, and a design BOM including the first-level subsystem node structure model and the interface model can be formed.
[0074] Step S330, defining and improving the vehicle design reference framework.
[0075] In the scheme design module, the vehicle layout, performance and other goals to be achieved are determined based on the technical specifications and key parameters of the vehicle. When using 3D collaborative design software for top-down 3D design, the design BOM structure, technical specifications and key parameters of the vehicle can be input, and this information can be converted into design data of the 3D collaborative design software and defined in the vehicle design benchmark skeleton, so that the vehicle design benchmark skeleton contains key parameters of the vehicle, vehicle position coordinate system and vehicle benchmark elements.
[0076] Step S340, creating the first-level skeleton of each subsystem based on the interface model in the scheme design stage and the vehicle design reference skeleton.
[0077] The design BOM structure, technical specifications and vehicle layout drawings can be input into the 3D collaborative design software. In the 3D collaborative design software, the first-level skeleton of each subsystem is created based on the interface model and the vehicle design benchmark skeleton, and the first-level skeleton of each subsystem is improved as the input requirement for the detailed design of the subsystem; the design BOM containing the first-level skeleton of the subsystem is finally output. The sub-models corresponding to each subsystem can be placed in the corresponding sub-areas on the first-level skeleton of the subsystem.
[0078] In the present disclosure, it is also possible to determine which sub-models need to communicate with each other based on the interaction requirements and data flows between the sub-models, and after determining the systems that need to communicate, a detailed specification can be formulated for the sub-model, which may include physical connections, data formats, communication protocols, etc. Subsequently, each coordination interface can be designed in detail based on the interface specification.
[0079] like Figure 1 As shown, in step S130, the technical design module forms component models corresponding to each of the sub-models and coordination interfaces between the component models, and verifies the second performance parameters of the subsystem structure composed of each of the component models.
[0080] For example, the overall designer can assign the design authority of the first-level subsystem node to each second-level subsystem node. After receiving the design task, the designer corresponding to the second-level subsystem node will carry out the detailed design of the subsystem. In this process, the design framework can be built for the lower-level system as needed and the design authority can be assigned to complete the detailed design of each level of the product.
[0081] In the present disclosure, the secondary subsystem designer can improve the secondary subsystem design skeleton and create a secondary skeleton in the subsystem skeleton assembly to complete the secondary subsystem skeleton assembly structure; the secondary subsystem designer can inherit the primary skeleton information in the subsystem design skeleton, and on this basis refine the geometric features that need to be published to the component model, define the geometry such as the component model design origin position, and at the same time, determine which component models need to communicate with each other based on the interaction requirements and data flows between the component models, and after determining the systems that need to communicate, formulate detailed specifications for the component model, which may include physical connections, data formats, communication protocols, etc.
[0082] The second performance parameter may be at least partially identical to the first performance parameter. The second preset standard may include a plurality of evaluation standards, that is, each type of second performance parameter is provided with an evaluation standard corresponding to the first performance parameter.
[0083] After completing the design of the component models and the coordinated interfaces between the component models, the subsystem structure composed of the component models can be simulated to verify whether the second performance parameter of the system structure composed of the component models meets the second preset standard, thereby verifying the feasibility of the subsystem structure composed of the component models.
[0084] For example, the subsystem structure composed of component models can be simulated through simulation software for the driver's cab field of view, dynamic performance, strength, heat dissipation performance, maintainability and ventilation. When each parameter meets the corresponding evaluation criteria, the component model of the subsystem structure is judged to be successfully built; if any one of the parameters does not meet the corresponding evaluation criteria, the component model of the subsystem structure is judged to have failed to be built, and it is necessary to rebuild the preliminary model of the whole vehicle or adjust the baseline skeleton of the subsystem or the key parameters of the subsystem structure.
[0085] In addition, the simulation software can be used to perform noise calculation and vehicle collision simulation on the subsystem structure composed of component models. When one of the noise calculation results and vehicle collision simulation results does not meet the corresponding evaluation criteria, it can also be judged that the construction of the component model of the subsystem structure has failed.
[0086] In some embodiments of the present disclosure, when the second performance parameter of the subsystem structure composed of component models does not reach the second preset standard, the component models can be reconstructed by adjusting the construction parameters of the component models and matching the component models to the preset positions on the main skeleton until the second performance parameter reaches the second preset standard.
[0087] like Figure 1As shown, in step S140, when the second performance parameter of the subsystem structure composed of the component models meets the second preset standard, each of the component models is transmitted to the construction design module, the construction design module annotates the component models with manufacturing information, and uses the subsystem structure composed of the component models with the manufacturing information as a three-dimensional annotated model.
[0088] The construction design module is mainly used to propose process manufacturing requirements for product production and provide a 3D digital prototype model containing product manufacturing information. During the design process of the construction design module, all product manufacturing information can be attached to the 3D digital prototype model, which is convenient for data transmission in subsequent process, production and operation and maintenance links. Based on the full 3D design mode, all manufacturing information can be marked in the 3D digital prototype model, making it a single data source for the process manufacturing integrated R&D model.
[0089] In an exemplary embodiment of the present disclosure, the construction design module may mark the manufacturing information on the component model (i.e., step S140) including steps S410 to S420, wherein:
[0090] Step S410: annotate the manufacturing information of the component model by three-dimensional annotation, wherein the manufacturing information includes at least one of material, size, roughness, processing tolerance requirement, benchmark, geometric tolerance or technical requirement.
[0091] Different component models can be 3D-annotated separately, and the manufacturing information marked on different components may be different. For example, component models that require specific processes and specific parameter requirements require special annotation.
[0092] In some embodiments of the present disclosure, additional attribute information of parts and components may be marked, and the attribute information may include whether it is a safety part, whether it is an eight-protection part, whether it is a casting or forging, whether it is a spare part, whether flaw detection is required, whether there are quality characteristic requirements, whether it is an identification part, component standard classification, design unit, designer, weight, etc.
[0093] In some embodiments of the present disclosure, welding information of parts may be additionally marked, and the welding information may include weld number, weld type, weld symbol, wood thickness, quality grade, defect acceptance grade and inspection grade, etc.
[0094] Step S420: Use a 3D model checking tool to check the 3D annotation model for compliance; and correct annotations that do not comply with business specifications.
[0095] In order to ensure that the data received in the subsequent links are accurate, the normative inspection of the 3D annotation model can also be carried out during the design process. For example, the normative inspection may include routine inspection, component inspection, assembly inspection, 3D standard inspection and interference inspection. Among them, routine inspection includes: model file number naming inspection, attribute inspection, component template inspection; component inspection includes: component routine inspection, opening feature inspection, sheet metal inspection; assembly inspection includes: assembly routine inspection and bolt inspection; 3D standard inspection includes: spectral field detection (Positive Material Identification, referred to as PMI) routine inspection and welding component inspection; interference inspection includes: static interference inspection, dynamic interference inspection and assembly interference inspection, etc.
[0096] The compliance check can be automatically and intelligently checked by a pre-written computer program or software, without the need for human intervention. The inspection process is comprehensive and highly reliable. After the inspection is completed, the non-standard parts can be automatically corrected to ensure the correctness of the data received by the back-end link.
[0097] In an exemplary embodiment of the present disclosure, the locomotive data evolution method based on full three-dimensional design of the present disclosure may also include:
[0098] Step S160, storing the three-dimensional annotation model in a solution model library, and reviewing and publishing the three-dimensional annotation model in a product data management system.
[0099] The 3D annotation model corresponding to the subsystem structure composed of the annotated component models can be stored in the solution model library, so that the model can be directly retrieved from the model library during the next design process, which helps to improve product design efficiency.
[0100] After completing the 3D annotation model in the 3D coordination design software, it can also be reviewed and released on the product data management system to manage the validity of the data. The reviewed and released data transmits the 3D annotation model to the process production operation and maintenance module process system through the integrated interface between the product data management system and the process management system for process design.
[0101] In an exemplary embodiment of the present disclosure, the review and release process may include inputting a table file (XML file), a component model physical file (.CATPRODUCT, .CATPART file), a three-dimensional annotation information PMI.xml file, etc. in the product data management system; wherein: the table file includes the basic information of the sub-model and its component model (mainly including the number, name, version, etc.), the assembly relationship and data structure link relationship of the sub-model and its component model, three-dimensional annotation information, summary attribute information, technical status information, review information, etc.; the product data management system may generate the design data to be synchronized into an xml file and a model physical file, and notify the PLM system. PLM reads the xml file and the model physical file, generates the product assembly and its component model information, and may generate the product assembly and its component visualization model and EBOM information, etc. according to the product assembly and its component model information.
[0102] For example, you can click the "PLM Data Synchronization" command on the 3D collaborative design software to generate "bom.xml", obtain the submitted 3D annotation model attributes and component structural information and write them, compress and package the 3D annotation model and its components and save them on the FTP server. The PLM system receives the 3D annotation model compression package and bom.xml submitted by VPM, parses the bom.xml structure and attributes, creates components with the same name and related drawing documents, synchronizes the attribute values filled in the 3D annotation model to the component object attributes in PLM, and builds the BOM structure at the same time. The constructed BOM structure can be reviewed during the review process, and the product data is finalized after the review process is completed.
[0103] like Figure 1 As shown, in step S150, the three-dimensional annotation model is transmitted to the process production operation and maintenance module, and the process production operation and maintenance module generates a three-dimensional process model and process steps according to the three-dimensional annotation model, and extracts the manufacturing information.
[0104] After the product data has completed the review process and finalized, the design materials, EBOM, 3D annotation models and related technical documents can be published to the process system of the process production and operation module through the integrated interface between the product data management system and the process management system. Process personnel can select the business data to be submitted in PLM, obtain the structural information of the parts, and send it to the process system; process personnel can also obtain BOM structure, materials, 3D annotation models and technical documents in PLM, and package these files and send them to the agreed area, and generate XML messages in the agreed area. After the process system receives the data information in PLM and parses the XML file, it will systematically create a process BOM in the Transmission Control Module (TCM) of the automobile, maintain material data, adjust process business data, and carry out process design. In this process, the 3D annotation model can be inherited as needed according to the product processing characteristics, and the 3D process steps can be generated. The 3D process steps can easily generate process models such as blanks, rough processing, and fine processing through the direct modeling technology of CAD software.
[0105] The 3D process model is based on the design model, inherits all the information of the design model, and transmits the design information in one direction. When the design model is changed, the process model can automatically update the related references.
[0106] In an exemplary embodiment of the present disclosure, the three-dimensional process model may include geometric information and non-geometric information, wherein the geometric information may include geometric entities, coordinate and reference information, reference model information and intermediate state information; the non-geometric information may include feature design information, manufacturing process information and attribute information. Geometric entities refer to product manufacturing geometric feature entities defined in a three-dimensional digital environment. This part of geometric entities uses manufacturing features as geometric units and can be summarized as shape geometric entities and boundary geometric entities. Shape geometric entities are used to express the contour features of the product, boundary geometric entities are used to express the connection transition features between components, and geometric entities usually also define the upper and lower tolerances required for the product. The establishment of geometric entities must be consistent with the actual processing process, and full consideration must be given to the convenience of the current geometric entities in inheriting, transferring and applying data for subsequent production and processing.
[0107] Coordinate systems are generally divided into global coordinate systems, local coordinate systems, and auxiliary coordinate systems. The global coordinate system is used to determine the real spatial position of the model; the local coordinate system is used to determine the spatial position of the model relative to a specific point; the auxiliary coordinate system is used to define the relative spatial position of the mounting parts outside the model. Datum information mainly includes positioning datum, process datum, measurement datum, and assembly datum. Coordinate and datum information are the main reference data for product digital definition and subsequent tooling design, product assembly, and inspection processes.
[0108] The process model is created by transforming and inheriting the design model information. The integration of information between the design model and the process model is achieved through the transformation of the intermediate reference model, that is, using the standardized defined model to realize the transmission of data information between different system platforms. Product reference model information generated by standards such as Step and Iges can realize the transmission and integration of information. However, it should be noted that there may be certain risks when transferring data through standard conversion models, which need to be checked and corrected.
[0109] The intermediate state information of modeling is the polymorphic process model information. The process model is a collection of sequentially evolved polymorphic process models. The existence of process models helps to express process information in an orderly manner and reproduce the design process. At the same time, the intermediate state process model can become a benchmark for the downstream process design stage, ensuring the effective transmission and expression of data information.
[0110] Feature design information refers to the design dimension information, datum information, tolerance information, roughness information, etc. involved in the process of creating the intermediate process model. Design information is generally inherited from the product design model and is the information basis for the process feature modeling process.
[0111] The manufacturing process information of the process model refers to the information set involved in the actual production and processing of the product, including processing methods, machine tools, clamping equipment, cutting tools, processing parameters, cutting fluids and other information.
[0112] The attribute information of the process model includes model description information (name, code, quality, description, etc.), model management information (version, edition, status, validity, etc.), approval information, manufacturing technical requirements, etc. Attribute information is a comprehensive description of various attributes of the process model, which can timely track and control the effective information of the process design and improvement process, and can effectively ensure the consistency, integrity and traceability of product data.
[0113] In an exemplary embodiment of the present disclosure, the process production operation and maintenance module can extract manufacturing information based on the 3D annotation model. For example, the manufacturing information attached to the 3D annotation model can be extracted into the process design and inspection requirements. The manufacturing information can be fully digested during the process design process, and the process production operation and maintenance module can also add process resource information based on the manufacturing information to ensure the accuracy and efficiency of the manufacturing process.
[0114] In this disclosure, the integrated PBOM editor can be used to view intuitive 3D models and corresponding linked EBOM information, assisting the design of PBOM, and allocating process assembly parts based on 3D visualization. Functions such as PBOM reconstruction, PBOM attribute editing, PBOM structure editing, design model and drawing viewing can be completed on a single interface.
[0115] In this exemplary embodiment of the present disclosure, the locomotive data evolution method based on full three-dimensional design of the present disclosure may also include:
[0116] Step S170, generating a three-dimensional process file and a three-dimensional inspection file after generating the three-dimensional process model and the process steps, wherein the three-dimensional process file includes the process steps, and the three-dimensional inspection file includes the inspection requirements.
[0117] The 3D process file may include detailed 3D process steps, and the 3D inspection file may include product inspection requirements. These two files can serve as the basis for production and quality control. During on-site operation, the workshop can display the 3D process file paperlessly on the terminal device. The 3D process file can directly guide on-site production operations. Paperless production reduces the use of paper documents and improves production efficiency and the accuracy of information transmission.
[0118] The 3D inspection file can be imported into the process inspection equipment, and the physical object after manufacturing can be compared with the 3D model through the process inspection equipment. The inspection report is generated and the inspection results are fed back to ensure that the manufacturing quality meets the design requirements.
[0119] In the present disclosure, during the production process, the production and manufacturing site information fed back by the production workshop can also be timely fed back and recorded through the platform integration mode. This feedback mechanism helps the process design department to understand the problems in production in a timely manner, and make corresponding adjustments and optimize the three-dimensional process files.
[0120] In this exemplary embodiment of the present disclosure, the locomotive data evolution method based on full three-dimensional design of the present disclosure may also include:
[0121] Step S180: Generate an electronic maintenance manual for the product, wherein the electronic maintenance manual for the product includes a maintenance operation flow.
[0122] The 3D annotation model can be used to create an electronic maintenance manual for the product, providing detailed maintenance instructions and operation procedures. Compared with traditional paper manuals, electronic maintenance manuals are more intuitive and easier to update.
[0123] The present disclosure also allows for fault prediction and health management of the 3D annotation model through professional industrial software to provide real-time monitoring and early warning functions, helping maintenance personnel to discover and handle potential problems in advance and extend product service life. The locomotive data evolution method based on full 3D design in the present disclosure not only improves the efficiency and accuracy of design and production, but also provides strong support for product operation and maintenance.
[0124] It should be noted that, although the steps of the vehicle body model design method in the present disclosure are described in a specific order in the accompanying drawings, this does not require or imply that the steps must be performed in this specific order, or that all the steps shown must be performed to achieve the desired results. Additionally or alternatively, some steps may be omitted, multiple steps may be combined into one step, and / or one step may be decomposed into multiple steps, etc.
