Description

Technical Field

[0001] The present application relates to the field of vehicle technology, and in particular to a PLM-based deformable parts management method, device, equipment and storage medium. Background Art

[0002] With the continuous maturity and popularization of PLM (Product Lifecycle Management) technology, PLM product data integration solutions have become a powerful tool for manufacturing companies to accelerate product innovation, reduce R&D costs and shorten product launch cycles. Therefore, it is no surprise that PLM product data integration solutions are also widely used in automobile manufacturing. In automobile manufacturing, deformable parts are a special state of parts in automobile design. These parts, such as wiring harnesses, sealing strips, hoses, springs, etc., are installed in different positions on the vehicle, or because of different body loads and postures, resulting in changes in parts before and after installation on different models or the same model; and in order to cope with this change, the same deformable original part needs to be deformed in the CAD (Computer Aided Design) end to support DMU (Digital Mockup) analysis and verification, and through DMU analysis and verification, problems can be found in advance in the design stage, thereby effectively shortening the R&D cycle and reducing R&D costs.

[0003] Among them, the above-mentioned deformation parts are generally used between different configurations of the same model and between different models. Referring to a newly developed basic model, the number of deformation parts involved is usually about 20-50. Assuming that the total number of basic models in production and research of a certain company is more than 400, then the number of deformation parts is about 8000-20000. It can be seen that for any car company, the number of deformation parts involved in the research and development of basic models will be huge, and with the continuous development of new models, the number of deformation parts will increase accordingly.

[0004] However, the current PLM product development field lacks standardized management of deformable parts. For example, in the current PLM product development process, the deformable part EBOM (Engineering Bill of Materials) data and the deformable part CADBOM (Design Material Digital Model Bill) data are constructed separately, which not only makes it difficult to control the consistency and continuity of the data, but also makes the digital model before deformation and the digital model after deformation side by side, so that when manually selecting the digital model after deformation, it is easy to mistakenly select the digital model before deformation, which leads to the assembly error of the deformable part DMU, ​​and the selection of the digital model after deformation needs to be re-performed, which increases the time consumption of DMU analysis and verification, making the efficiency of DMU analysis and verification low. It can be seen that how to achieve standardized management of deformable parts is an urgent problem to be solved. Summary of the invention

[0040] The embodiments of the present application provide a PLM-based deformable parts management method, apparatus, device and storage medium, which can solve the problem that the standardized management of deformable parts cannot be achieved in the related art.

[0041] In order to better explain this application, the abbreviations and key terms involved in this application are explained as follows:

[0042] Deformed parts: The same component needs to change its shape when installed in different parts of the vehicle. Such parts are called deformed parts, such as hoses and springs. The changed components are called deformed parts.

[0043] Deformed parts: refers to the parts used to define the functional requirements of the actual installed parts. This part defines the actual model space position and the object of the fastening connection method with the surrounding parts. It is used for the later selection / guidance of suppliers for the actual installation parts design.

It is one of the basic data for procurement, process, production and finance.

[0047] One object, multiple numbers: The same physical object (such as a deformed part) corresponds to multiple part numbers.

[0048] See also Figure 1 and Figure 2As shown, the embodiment of the present application provides a deformable parts management method based on PLM, comprising the following steps:

[0049] Step S10: The EBOM management module creates multiple deformations of the deformation part corresponding to the deformation part original based on the coding of the deformation part original, and there is a mapping relationship between the coding of the deformation part deformation and the coding of the deformation part original; wherein the coding of the deformation part deformation is generated based on a preset coding rule, and the preset coding rule is that the coding of the deformation part deformation includes the coding of the deformation part original corresponding to the deformation part deformation, preset letters and the sequence number of the deformation part deformation.

[0050] Step S20: the EBOM management module creates a deformable part EBOM data structure based on preset deformable part assembly requirements, the deformable part deformation, and a mapping relationship between the deformable part deformation code and the original code of the deformable part;

[0051] Step S30: the CADBOM integration module creates a deformable part CADBOM data structure based on the deformable part EBOM data structure, and generates a 3D digital model corresponding to each deformable part according to a preset digital model assembly relationship and the deformable part CADBOM data structure;

[0052] Step S40: The DMU analysis module analyzes and verifies the 3D digital model corresponding to each deformation of the deformable part based on the preset digital model assembly relationship and the CADBOM data structure to obtain the analysis and verification results of the deformation of each deformable part.

[0053] Demonstrably, PLM product data integrated management generally includes EBOM product design management module, CAD digital model integration management module, change management module, product configuration management module, DMU analysis module, MBOM management module, etc.; each company can realize the integration between different modules according to its own business development needs. The integrated solution provided in this embodiment is to design the business integration solution of EBOM, CADBOM, MBOM, and DMU. This solution realizes the automatic synchronization between EBOM structure and CADBOM, and uses EBOM data to directly drive the development and design of the whole vehicle and the digital virtual prototype verification DMU, ​​thereby realizing an end-to-end product collaborative development process, reducing manual links, shortening the data construction cycle as a whole, and ensuring the accuracy, integrity, uniqueness and continuity of data construction.

[0054] However, when conducting PLM product development, this applicant found that: the current PLM product development field lacks standardized management of deformable parts, resulting in complex and diverse data construction, difficult control, and difficulty in business development, which is mainly manifested in the following aspects:

[0055] (1) The EBOM data of deformable parts is constructed separately from the CADBOM data, and data consistency and continuity are difficult to control. The current management method for deformable parts on automobiles is: in the deformable part design stage, the EBOM end only reflects the original part information of the deformable part, but not the deformation information of the deformable part; the deformation design of the deformable part is mainly on the CADBOM end, that is, on the CADBOM end, different digital model files are defined for the same deformable part original according to different deformable part forms, so that it is impossible to use EBOM data to directly drive the development and design of the deformable parts of the whole vehicle, resulting in inconsistency between EBOM data and CADBOM data, and it is impossible to achieve end-to-end collaborative development, which in turn makes it difficult to control data consistency and continuity.

[0056] (2) The assembly of deformable parts DMU is prone to errors, time-consuming and inefficient. Since EBOM data and CADBOM data are constructed separately, EBOM data cannot directly drive DMU analysis and verification. For example, in the DMU verification stage, Assembly 1 should select the digital model file of deformable part 1, but because the digital model before deformation and the digital model after deformation are designed together, the designer needs to manually hide the digital model before deformation and select different deformable parts for assembly as needed; since the above process completely relies on the designer's experience and memory, it is often easy to have the problem that the final selection may be the digital model file of deformable part 2, and this problem will only be discovered during the DMU verification, that is, the digital model selection error is discovered during the DMU verification, so it needs to be deleted and re-selected, which leads to such a repetitive and inefficient design process, and also increases the probability of error risk, which increases the data preparation cycle of the vehicle DMU. For example, a job that could have been completed in 2 hours may actually take 2 weeks or even longer to complete, which not only prolongs the entire R&D cycle, but also increases R&D costs.

[0057] The PLM system in this embodiment includes an EBOM management module, a CADBOM integration module, a DMU analysis module, and an MBOM management module. The EBOM management module in the PLM system can be used to create multiple deformations of deformed parts based on the original deformed parts and automatically generate the code of each deformation of the deformed parts, and all the properties of the deformation of the deformed parts are copied from the original deformed parts; wherein, the code of the deformation of the deformed parts is automatically generated by the system according to the coding rules, for example, the code of the deformation of the deformed parts is the original deformation code-C+3-digit sequence number. It should be noted that, of course, the specific coding rules can also be determined according to actual needs, as long as the deformation of the deformed parts and the original deformed parts can be associated, that is, the EBOM management module will automatically establish a mapping relationship between each deformation of the deformed parts and the corresponding original deformed parts when saving each deformation of the deformed parts. For example, the code of the original deformed parts is part 1, and there are two corresponding deformations of the deformed parts, then the codes of the two deformations of the deformed parts are part 1-C001 and part 1-C002 respectively.

[0058] The EBOM management module references the deformation of the deformable part under the structure of the assembly according to the preset actual assembly requirements of the deformable part. For example, the preset actual assembly requirements of the deformable part are: Assembly 1 (quantity 1) is composed of the deformable part deformation coded as part 1-C001 (quantity 1) and the deformable part original coded as part 2 (quantity 1) (i.e., part 2 does not need to be deformed in assembly 1). Then, according to the preset actual assembly requirements of the deformable part and the mapping relationship between the codes of the deformable part deformation and the codes of the deformable part original, the deformable part deformation coded as part 1-C001 can be selected from all the deformable part deformations corresponding to the deformable part original coded as part 1 and referenced to the structure of assembly 1, and the deformable part original coded as part 2 is referenced to the structure of assembly 1, thereby generating the deformable part EBOM data structure corresponding to assembly 1. It can be seen that the deformable part EBOM data structure stores part 1-C001 and its quantity, part 2 and its quantity, which have a structural relationship with assembly 1.

[0059] After completing the creation of the deformable part EBOM data structure of assembly 1, the EBOM management module will automatically synchronize the EBOM structure information containing the deformable part EBOM data structure to the CADBOM integration module, and the CADBOM integration module can automatically build the deformable part CADBOM data structure based on the deformable part EBOM data structure; then the CADBOM integration module can perform digital-model assembly design on each deformable part in the deformable part CADBOM data structure according to the preset digital-model assembly relationship, such as performing digital-model assembly design on part 1-C001. Of course, the CADBOM integration module will also perform digital-model assembly design on the deformable part originals (such as part 2) in the CADBOM data structure according to the preset digital-model assembly relationship, and then obtain the 3D digital model corresponding to each deformable part deformation and the 3D digital model corresponding to each deformable part original. For example, the CADBOM data structure corresponding to assembly 1 stores the part 1-C001.product file and the part 1-C001-P000.part file corresponding to part 1-C001 that has a structural relationship with assembly 1, and the part 2.product file and the part 2-P000.part file corresponding to part 2.

[0060] See also Figure 3As shown, after the CADBOM integration module completes the digital model assembly design, the above-mentioned related CADBOM information will be synchronized to the EBOM management module, and the CAD data will be transmitted to the DMU analysis module; the DMU analysis module will perform professional DMU analysis and verification, that is, according to the preset digital model assembly relationship and CADBOM data structure, the 3D digital model corresponding to each deformed part deformation (such as part 1-C001) and the 3D digital model corresponding to each deformed part original that does not need to be deformed (such as part 2) are analyzed and verified, and the analysis and verification results of each deformed part deformation and each deformed part original are obtained. Finally, the association relationship between the deformed part deformation and the deformed part original can be published, and the design of the deformed part is completed. It can be seen that this embodiment can directly generate a DMU inspection report based on the CADBOM definition content for inspection and analysis, without the need to perform DMU analysis by manually selecting the deformation of the deformed part and assembling it on demand.

[0061] Therefore, through this embodiment, a mapping relationship between the deformation of the deformable part and the encoding of the original deformable part is created to achieve automatic synchronization between the deformable part EBOM data structure and the CADBOM data structure, so that the DMU analysis and verification of the deformable part of the whole vehicle can be directly driven by the deformable part EBOM data structure, that is, the integrated standard management of the deformable part from the EBOM data structure to the CADBOM data structure and DMU analysis is achieved, so as to ensure the consistency and continuity of the deformable part data construction; in addition, the automatic filtering and assembly of the DMU analysis and verification can be performed based on the CADBOM data structure, that is, the assembly entity is the deformation form of the required deformable part, and there is no need to manually select the required deformation digital model of the deformable part for DMU analysis, which can shorten the DMU data preparation cycle of the whole vehicle from the original 2 weeks to 2 hours, greatly improving work efficiency and data quality.

[0062] In summary, this embodiment aims to solve the problem that the consistency and continuity of data are difficult to control due to the separate construction of the EBOM data and CADBOM data of the deformable parts. A deformable parts design method based on the integrated management of PLM product data is proposed to achieve automatic synchronization between the EBOM structure of the deformable parts and CADBOM, so that the EBOM data of the deformable parts can be used to directly drive the development and design of the deformable parts of the whole vehicle and the analysis and verification of the DMU, ​​thereby achieving end-to-end collaborative development to ensure the consistency and continuity of the construction of the deformable parts data. In addition, this embodiment solves the problems of easy errors, repeated designs, low efficiency and long data preparation cycle caused by the on-demand manual assembly of the DMU by realizing the integrated management of the deformable parts data.

[0063] Further, after the step of creating the deformable part EBOM data structure by the EBOM management module based on the preset deformable part assembly requirements, the deformable part deformation, and the mapping relationship between the deformable part deformation code and the original code of the deformable part, the step further includes:

[0064] The EBOM management module solves the EBOM data structure of the deformed part based on the mapping relationship between the deformed code of the deformed part and the code of the original part of the deformed part to obtain an EBOM detailed list.

[0065] Further, after the step of creating the deformable part EBOM data structure by the EBOM management module based on the preset deformable part assembly requirements, the deformable part deformation, and the mapping relationship between the deformable part deformation code and the original code of the deformable part, the step further includes:

[0066] The MBOM management module converts the deformation of the deformable part in the deformable part EBOM data structure into the corresponding deformable part original based on the mapping relationship between the code of the deformation of the deformable part and the code of the deformable part original to obtain the MBOM data structure;

[0067] The MBOM management module defines each parameter in the MBOM data structure based on preset manufacturing parameter information to generate a new MBOM data structure, wherein the manufacturing parameters include process assembly parameters, manufacturing route parameters, and assembly route parameters;

[0068] The MBOM management module solves the new MBOM data structure to obtain an MBOM detail table.

[0069] Exemplarily, when conducting PLM product development, this application also found that: due to the lack of standardized management of deformable parts in the current PLM product development field, the problem of multiple numbers for one object has occurred, which has led to high costs for parts production and procurement, making it difficult to control the cost of the entire vehicle. Specifically, in order to avoid the problem that EBOM data and CADBOM are constructed separately, which leads to data consistency and continuity being difficult to control, and DMU assembly being prone to errors and inefficiency, you can choose to apply for multiple deformable part deformation numbers for the same deformable part original on the EBOM side to match the DMU verification needs between different models or the same models with different configurations, and use the integrated solution of EBOM, CADBOM, DMU and MBOM to achieve end-to-end collaborative development and avoid manual intervention. However, the deformation number of the deformation part has nothing to do with the coding of the deformation part original. For example, for the same deformation part original A (assuming that the deformation part original A is coded as part 3), it needs to be deformed and applied to three vehicle models, that is, the deformation part original A needs to correspond to three deformation parts. At this time, three deformation parts deformations A1, A2 and A3 can be applied for A, and the corresponding codes of A1, A2 and A3 are deformation part deformation 1, deformation part deformation 2 and deformation part deformation 3.

[0070] It can be seen from this that another problem will arise at this time. That is, according to the integrated collaborative solution, when the EBOM product list and the MBOM manufacturing list are solved, the part number solved in the list is the deformation number of the deformed part, rather than the original part number of the deformed part. As a result, the same model with different configurations or different models have multiple numbers for the same item, which increases the difficulty of controlling the development and changes of deformed parts, and can easily cause confusion in downstream procurement, quality, and supplier control, and the control costs will increase exponentially.

[0071] In this embodiment, since a mapping relationship is created between the code of the deformed part and the code of the original part of the deformed part, the EBOM management module will automatically convert the deformed part into the original part of the deformed part according to the association relationship between the original part of the deformed part and the deformed part when solving the product list. Specifically, assuming that the deformed part EBOM data structure stores part 1-C001 and its quantity, part 2 and its quantity that have a structural relationship with assembly 1; when solving the EOM data structure, when solving to part 1-C001, the deformed part coded as part 1-C001 will be automatically converted into the original part of the deformed part coded as part 1 according to the mapping relationship between part 1-C001 and the original part of the deformed part coded as part 1. Therefore, the deformed part coded as part 1-C001 will not appear in the EBOM product list obtained by settlement, but only the original part of the deformed part coded as part 1 will appear, thereby solving the problem of multiple numbers for one item and effectively controlling the cost of parts and vehicles.

[0072] Similarly, after receiving the EBOM data structure transmitted by the EBOM management module, the MBOM management module will first automatically convert the deformed part coded as part 1-C001 into the deformed part coded as part 1 according to the mapping relationship between the code of the deformed part and the code of the original part. At the same time, according to the mapping relationship between the code of the deformed part and the code of the original part, it can be known that part 2 is the original part of the deformed part, so there is no need to convert part 2, that is, part 2 is still part 2, and then the MBOM data structure is obtained; it can be seen that there is no deformed part deformation in the MBOM data structure but only the original part of the deformed part, and on this basis, manufacturing parameters such as process assembly, manufacturing route, and assembly route can be defined to generate a new MBOM data structure, and finally the new MBOM data structure is directly solved to obtain the MBOM manufacturing details. Therefore, only the relevant manufacturing information of the original part of the deformed part will appear in the MBOM manufacturing details, thereby solving the problem of multiple numbers for one object, effectively controlling the cost of parts and vehicles, and improving market competitiveness.

[0073] In summary, this embodiment implements the deformation management method of deformable parts through the integrated management mode of PLM product data, and realizes the integrated management process of deformable parts from EBOM structure to CADBOM, MBOM, and DMU. Through the deformation conversion management solution of deformable parts in the EBOM product list and the MBOM manufacturing list, automatic filtering and solving of the list is realized, which not only ensures efficiency but also reduces costs.
