[0033] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0034] For spare parts data management, there are several common solutions for OEMs:

[0035] A. The spare parts are mounted as sub-parts of the design parts in DBOM. The EBOM structure is highly consistent with the DBOM structure. The storage method is as follows: Figure 1 shown.

[0036] B. Spare parts and design parts are linked to the same DBOM structure, but use the after-sales dedicated IA and are managed separately from the design data. The EBOM structure is highly consistent with the DBOM structure. The storage method is as follows: Figure 2 shown.

[0037] C. Spare parts are not linked to DBOM and EBOM, but are created directly in the SBOM management system. Their storage method is as follows: Figure 3 shown.

[0038] Among them, it should be noted that Figure 1 、 Figure 2 and Figure 3 P in it represents the designed part, S1 and S2 represent the spare parts, and IA represents the design data.

[0039] The three common solutions mentioned above are developed by different OEMs based on their own data management systems. While reasonable, they also have certain flaws:

[0040] Solution A: The split spare parts always maintain a high degree of consistency in DBOM and EBOM. The design information can be well synchronized to the split spare parts. However, the split parts must be saved as product types in CATIA. The product type data is an assembly structure, which is relatively complex to build. If the product type data is upgraded, each of the following sub-parts needs to be upgraded, and the workload of subsequent change management is very large.

[0041] Plan B uses a dedicated after-sales IA to attach split spare parts to the DBOM and EBOM. This reduces management complexity compared to Plan A and can also achieve a certain level of information synchronization. However, R&D needs to manage the IA structures of both R&D and after-sales, which is a relatively large workload.

[0042] Solution C: Split spare parts are only managed in the SBOM and have no direct connection with the design data. It is simple to create and flexible to manage, but it is difficult to achieve synchronous development and design changes between split spare parts and design data.

[0043] Before describing the method proposed in the embodiment of the present invention, the technical concepts involved are described, including: EBOM: Engineering Bill of Material; DBOM: Design Bill of Material; SBOM: Service Bill of Material; EPC: Electronic Parts Catalog; IA: Installed Assembly.

[0044] Example 1

[0045] Based on the above-mentioned defects of the existing different solutions, the present invention proposes a method for associating spare parts with design data, see Figure 4 The association method includes: S1, establishing an association relationship between the design part and the design data in the DBOM structure; S2, using the spare part split part as the spare part split feature of the design part in the digital model structure tree to establish the relationship between the spare part split part and the design part; S3, hanging the spare part split part as a sub-part of the design part in the EBOM structure.

[0046] Among them, the principle of the spare parts data management solution proposed in the present invention is: only design data is attached to the DBOM, and spare parts split parts are not attached, and the design parts are saved as part type in CATIA. However, in the CATIA digital model structure tree, the part that needs to be split is regarded as a split feature of the design part, and the corresponding split feature is named with the part number of the spare parts split part. The corresponding split feature can also be named with the part number and attribute information of the spare parts split part, thereby establishing the relationship between the spare parts split part and the design data; in the EBOM, the spare parts split parts are attached as design part sub-parts, and the EBOM structure reflects both the DBOM structure and the structure of the digital model structure tree. While realizing the association, the above solution greatly reduces the time cost of research and development because there is no need to split the DBOM.

[0047] Specifically, the core of the present invention is to utilize the editable feature name in the digital model structure tree to manage the relationship between the spare parts and the design data. From the upstream DBOM structure / digital model structure tree / EBOM structure to the downstream EPC atlas, the overall solution consists of 4 parts. Figure 5 , the data stored in the three data structures are as follows:

[0048] 1. Manage the relationship between design parts P and design data in the DBOM structure;

[0049] 2. Manage the relationship between the spare parts S1 / S2 and the design part P in the digital model structure tree (key);

[0050] 3. The EBOM structure reflects the complete DBOM structure and the structure of the digital model structure tree.

[0051] 4. The EPC atlas uses the exploded view of the 3D digital model, combined with spare parts information such as part codes and part names managed in the EBOM and SBOM, to create an atlas for terminal spare parts ordering and inquiry.

[0052] The specific working process is:

[0053] (1) In the early stage of vehicle development, after-sales service inputs the demand for spare parts splitting. R&D applies for the part number of the spare parts split when creating the digital model, and names the split features with the part number in the digital model structure tree, and builds the DBOM structure tree at the same time; when the data is frozen, the DBOM structure and the digital model structure tree are fully checked, and the correspondence between the EBOM structure and the two is checked.

[0054] (2) For design changes that occur after data is frozen, R&D will identify whether the design changes affect the spare part splitting characteristics based on the digital model structure tree, and thus decide whether it is necessary to apply for a new spare part split part number to update the naming, so as to always keep the spare part split part and design data updated synchronously.

[0055] (3) When preparing the EPC atlas, after-sales service can quickly locate the features of the split spare parts in the digital model structure tree through the part number of the split spare parts, so as to identify the atlas.

[0056] Example 2

[0057] A system for associating spare parts with design data, see Figure 6 The association system includes a first establishment module 601, a second establishment module 602 and a mounting module 603.

[0058] The first establishing module 601 is used to establish an association relationship between the design parts and the design data in the DBOM structure;

[0059] The second establishing module 602 is used to establish a relationship between the spare part split part and the design part by using the spare part split part as the spare part split feature of the design part in the digital model structure tree;

[0060] The attachment module 603 is used to attach the split spare part to a sub-part of the designed part in the EBOM structure.

[0061] Among them, the second establishment module 602 is used to use the spare part split part as the spare part split feature of the design part in the digital model structure tree to establish the relationship between the spare part split part and the design part, including: applying for the part number of the spare part split part according to the spare part splitting requirements, using the part number and attribute information of the spare part split part as the split feature of the design part, representing the spare part split part with the split feature, and establishing the relationship between the spare part split part and the design part.

[0062] The association system proposed in the present invention also includes a synchronous update module 604, which is used to identify whether the design data change affects the spare part splitting characteristics through the digital model structure tree when the design data changes, and then determine whether it is necessary to apply for a new spare part split part number to update the name of the spare part splitting characteristics, so as to keep the spare part split parts and the design data updated synchronously.

[0066] 2. Design data is saved in CATIA as part type (the data type submitted by suppliers to OEMs). It does not need to be converted into product type, nor does it need to be linked to spare parts in DBOM, which greatly reduces the workload of R&D data processing and post-management.
