And according to the corresponding relation between the part number in the configuration layer part list and the part number in the part basic information, the configuration dotting information in the configuration layer part list is moved to a configuration column included in the part basic information, and the part configuration information is obtained.
In some embodiments, determining weight and center of gravity information of the target single configuration whole vehicle based on the part configuration information comprises:
Determining the weight of the target single configuration whole vehicle according to the weight of each part and the consumption information of each part included in the part configuration information;
And determining the gravity center information of the target single configuration whole vehicle according to the gravity center information, the weight and the relative conversion matrix information of each part included in the part configuration information.
All the above optional technical solutions may be combined according to any choice to form an optional embodiment of the present embodiment, which is not described in detail herein.
Fig. 3 is a flowchart of a method for determining weight and center of gravity information of a single-configuration whole vehicle according to an embodiment of the present application, and referring to fig. 3, the method includes the following steps.
Step 301: the terminal acquires a configuration layer part list of a target whole vehicle in the configuration layer management system and part basic information in a CAD data view of the target whole vehicle product in the PDM system.
Because the data of some parts may change during the design process of the target whole vehicle, for example, the shape, weight, model, number and the like of the parts may change, in order to ensure the accuracy of the weight and gravity center information of the target single configuration whole vehicle, the terminal can acquire the configuration layer part list of the target whole vehicle in the configuration layer management system and the part basic information of the CAD data view of the target whole vehicle product in the PDM system.
As an example, the operation of the terminal to obtain the configuration layer part list of the target whole vehicle in the configuration layer management system and the part basic information of the CAD data view of the target whole vehicle product in the PDM system at least includes: acquiring a configuration layer part list of a target whole vehicle from a configuration layer management system; assembling configuration layer parts in the configuration layer part list into a CAD data view of a target whole vehicle product in a PDM system; and acquiring the part basic information in the CAD data view of the product.
The configuration layer part list of the target whole vehicle is positioned in a configuration layer management system, and the terminal can acquire the configuration layer part list of the target whole vehicle from the configuration layer management system; when the configuration layer part list changes, the part view structure of the CAD data view of the whole vehicle is changed, so that the terminal needs to re-acquire the configuration layer part list of the target whole vehicle from the configuration layer management system, assemble the configuration layer parts in the configuration layer part list into the CAD data view of the target whole vehicle in the PDM system, and acquire the part basic information of the CAD data view of the product.
It should be noted that the configuration layer parts bill can include a part number, a chinese name, a configuration description, configuration dotting information, and the like. The part basis information can include part number, chinese name, weight, center of gravity information, hierarchy, usage, relative transformation matrix, and so forth.
In some embodiments, in order to ensure the correctness of the CAD data view of the target whole vehicle product, after determining the configuration layer part list and the part basic information, the terminal needs to compare the information belonging to the configuration layer in the configuration layer part list with the information belonging to the configuration layer in the part basic information, and when the information of the configuration layers is inconsistent, modify the inconsistent information to ensure that the information of the two configuration layers are consistent.
In some embodiments, before the terminal obtains the configuration layer part list of the target whole vehicle from the configuration layer management system, the terminal can also obtain the CAD data attribute information of the target whole vehicle product from the PDM system, and check whether the CAD data attribute information of the product meets the check condition; when the product CAD data attribute information accords with the checking condition, determining whether the configuration layer part list in the product CAD data attribute information is updated or not; when the configuration layer part list is updated, the operation of acquiring the configuration layer part list of the target whole vehicle from the configuration management system is executed.
It should be noted that the product CAD data attribute information can include at least basic information required for calculating weight and center of gravity information, such as a material brand, density, thickness, surface area, volume, and the like.
As an example, when acquiring the product CAD data attribute information, the terminal can check whether the format of the product CAD data attribute information is the same as the preset format by the checking tool, i.e., the terminal can check the normalization and correctness of the product CAD data attribute information by the checking tool.
In some embodiments, when the product CAD data attribute information meets the inspection conditions, the terminal can generate a pass-through identifier to indicate that the product CAD data attribute information meets the inspection conditions. And when the product CAD data attribute information meets the checking condition, determining whether the configuration layer part list in the product CAD data attribute information is updated.
Before determining whether the configuration layer part list in the product CAD data attribute information is updated, the terminal can also release and freeze the product CAD data attribute information through a release change management system.
As an example, the terminal derives a problem list when the product CAD data attribute information does not meet the inspection condition.
In some embodiments, after the terminal derives the problem list, the user can modify the product CAD data attribute information according to the problem list, and then the terminal re-executes to obtain the target whole vehicle product CAD data attribute information, and checks whether the product CAD data attribute information meets the check condition, until the product CAD data attribute information meets the check condition.
Step 302: and the terminal combines the configuration layer part list and the part basic information to obtain part configuration information.
Because the configuration layer part list and the part basic information respectively comprise different part information of the target whole vehicle, in order to accurately and completely determine the weight and gravity center information of the target single configuration whole vehicle, the terminal needs to combine the configuration layer part list and the part basic information to obtain the part configuration information.
As an example, the operation of the terminal to obtain the part configuration information by combining the configuration layer part list and the part basic information can at least include: and according to the corresponding relation between the part numbers in the configuration layer part list and the part numbers in the part basic information, the configuration dotting information in the configuration layer part list is moved to a configuration column included in the part basic information, and the part configuration information is obtained.
Because the part basic information not only comprises the configuration information of the configuration layer, but also comprises the configuration information of other layers with the hierarchy lower than the configuration layer, for example, the part layer dotting information, when the terminal merges the configuration layer part list and the part basic information, the terminal can not only move the configuration dotting information in the configuration layer part list into the configuration column included in the part basic information, but also write the dotting information of the configuration layer in the part basic information into the configuration column corresponding to the single part according to the principle that the configuration information of the single part is equal to the configuration information of the configuration layer.
The arrangement may include weight and center of gravity information of each component. The barycentric information can include barycentric coordinates (x, y, z).
In some embodiments, the terminal may further send the configuration layer part list and the part basic information to the basic information management platform, and when the basic information management platform receives the configuration layer part list and the part basic information, the configuration layer part list and the part basic information may be combined to obtain the part configuration information.
As an example, before the terminal sends the configuration layer part list and the part basic information to the basic information management platform, the terminal can also store the configuration layer part list as a first file in a custom format, store the part basic information as a second file in the custom format, and send the first file and the second file to the basic information management platform.
It should be noted that the first file and the second file can carry storage time, and versions of the first file and the second file stored at different times may be the same or different.
It is worth to say that, because the terminal can save the configuration layer part list and the part basic information respectively through the custom format, and because the first file and the second file can store different versions according to the storage time, the traceability of the configuration information is ensured.
Step 303: and the terminal determines the weight and gravity center information of the target single configuration whole vehicle according to the part configuration information.
Because the part information in the configuration layer part list may change, the part information in the part basic information may also change, and because the weight and the gravity center information of the target single configuration whole vehicle are affected when the bottom part of the target whole vehicle is changed, if the weight and the gravity center information of the whole vehicle cannot be synchronously changed in time, the weight and the gravity center information of the target single configuration whole vehicle are wrong, so that in order to accurately acquire the weight and the gravity center information of the target single configuration whole vehicle, the terminal determines the weight and the gravity center information of the target single configuration whole vehicle according to the part configuration information.
As an example, the operation of the terminal to determine the weight and center of gravity information of the target single configuration whole vehicle according to the part configuration information at least includes: determining the weight of the target single configuration whole vehicle according to the weight of each part and the consumption information of each part included in the part configuration information; and determining the gravity center information of the target single configuration whole vehicle according to the gravity center information, the weight and the relative conversion matrix information of each part included in the part configuration information.
In some embodiments, the terminal determines the weight of the target single configuration whole vehicle by from a first formula described below, based on the weight of each part and the usage information of each part included in the part configuration information.
In the first formula (1), M is the weight of the target single-configuration whole vehicle, n is the number of parts of the target single-configuration whole vehicle, M i is the weight of the i-th part, and s i is the number of used parts of the i-th part.
