The invention does not limit the changed form template at all, and engineering designers can customize and change the specific content of the form template according to self requirements. By setting the modification form template, the part attribute information corresponding to the part identifier of the pre-modified part acquired in step 101 can be automatically filled in the corresponding item of the modification form template, so as to form a part attribute form of the pre-modified part and provide the part attribute form to the user. The part attribute form may include the previous design change information of the pre-changed part, or may include the past design change information of the pre-changed part, and may be specifically set by the engineer who made the change form template. And the user carries out design change of the corresponding item on the attribute characteristics of the part to be changed at this time according to the item on the part attribute form to obtain the part attribute information corresponding to the part identification after the change.
And 103, sending the modified part attribute information to a storage server so that the storage server adds the modified part attribute information to a part attribute set corresponding to the part identifier.
The part design changing system sends the changed part attribute information to the storage server, wherein the changed part attribute information can be the part attribute information which is only changed in the part attribute form and sent to the storage server for increasing the part attribute information, namely, the changed part attribute information is stored as a new record; or all the part attribute information in the part attribute form after the change is sent to a storage server for updating the part attribute information, namely all the latest part attribute information of the part is stored as a new record. Therefore, the part attribute information in the part attribute set may be stored in a manner that stores the part attribute information of the design change portion after each part change as new information, or stores all the latest attribute information on the part after each part design change as new information. No matter which type of storage form of the part attribute information is adopted, the purpose that the part design change records are arranged according to the order of the part change versions is achieved. It should be noted that the above different storage manners are only used to illustrate the technical solution of the present invention, and are not limited thereto, and all storage schemes that are in accordance with the sequence of the part design change record and the part change version are all within the protection scope of the present invention.

Step 202, copying the acquired part attribute information to a part folder before change.
The part design changing system copies the acquired part attribute information to a part folder before changing so as to improve the subsequent processing speed of the part attribute information. Generally, when many parts are needed to be designed and changed in a product, the data size of the part attribute information corresponding to the pre-changed part is large, in order to increase the data processing speed, the part attribute information acquired from the storage server is copied into a pre-changed part folder, and the pre-changed part folder is used as a cache and can be used for temporarily storing the part attribute information of the pre-changed part, so that convenience is provided for high-speed exchange of data and synchronous use of data.
Step 203, calling part attribute information from the part folder before change, and correspondingly filling the called part attribute information into the change form template to obtain the part attribute form.

After the part attribute information is modified, the technical modification influence analysis, feasibility evaluation, risk evaluation and the like of an analysis and evaluation department are generally required. And when the analysis and evaluation result is qualified, generating a part change notice for the design change part formally, and issuing the part change notice to a part processing device of a production department for batch production.
After receiving an analysis and evaluation request of a user, the part design changing system acquires part evaluation information corresponding to the part identification from the storage server according to the part identification in the analysis and evaluation request, wherein the part evaluation information is past history evaluation information of the part to be changed, and the past history evaluation information can be used as reference data of the evaluation, so that the efficiency and the accuracy of the evaluation can be improved. The engineer can select the version number of the reference historical evaluation information according to the change requirement or importance of the part design. The analysis evaluation device correspondingly fills the part evaluation information into the reference data template to obtain an evaluation information form, the evaluation information form can contain various information related to the part, such as part material evaluation information, part size ratio evaluation, part collocation model feasibility analysis and the like, and the content of the specific information can be set by engineering personnel according to requirements and is used as the content of the preset attribute format of the reference data template.
And the analysis and evaluation device fills the evaluation data of the design change part into the evaluation information form according to the changed part attribute information and the historical evaluation information of the change part recorded in the evaluation information form, and provides analysis and evaluation result information which is used as a guidance basis for whether the subsequent part is subjected to mass production.
And step 206, if the analysis and evaluation result information is qualified, sending the modified part attribute information to a storage server so that the storage server adds the modified part attribute information to a part attribute set corresponding to the part identifier, and if the analysis and evaluation result information is unqualified, continuing to execute step 204.
If the analysis and evaluation result information given by the analysis and evaluation device is qualified in step 205, the part design modification system sends the modified part attribute information with the analysis and evaluation result information being qualified to the storage server. The specific implementation process of this step refers to step 103 in the method embodiment shown in fig. 1, and is not described here again.

The analysis and evaluation result information is added to the part evaluation information set corresponding to the part identification, so that the part analysis and evaluation information can be stored in order according to the part change version information, and the traceability of the part analysis and evaluation information is greatly improved.
Step 207, sending the modified part attribute information with the analysis and evaluation result information being qualified to a drawing modification device; receiving drawing design change information sent by the drawing change device, wherein the drawing design change information is obtained by drawing the drawing change device according to the changed part attribute information; and sending the drawing design change information to a storage server so that the storage server adds the drawing design change information to a drawing design change information set corresponding to the part identifier.
Before mass production, the part processing device of the production department needs to refer to the analysis and evaluation result information as qualified modified part attribute information and also needs to refer to drawing information for part design modification according to the qualified modified part attribute information.
The part design changing system sends the changed part attribute information of which the analysis and evaluation result information is qualified to the drawing changing device, receives the drawing design changing information sent by the drawing changing device, and sends the drawing design changing information to the storage server, so that the storage server adds the drawing design changing information to a drawing design changing information set corresponding to the part identification.
