There are already some technical means for controlling part deformation, such as optimizing the processing technology, using high-performance materials, etc. For example, after the part design is completed, the deformation amount of the part can be obtained through mold flow analysis. Designers can add a pre-deformation amount to the part according to the deformation amount of the part, and then perform mold flow analysis again, and determine whether the actual size of the part meets the design size of the part according to the results of the mold flow analysis. When the actual size of the part does not meet the design size of the part, designers adjust the pre-deformation amount multiple times according to work experience and perform mold flow analysis to make the actual size of the part match the design size. However, this process requires designers to adjust repeatedly for many times, reducing the work efficiency of designers.

[0010] By adopting the above technical solution, the applied loading conditions of the part are obtained, that is, the forces and pressures on the part in the actual use environment, etc. At the same time, it is also necessary to understand the material properties of the part, including information such as the strength and elastic modulus of the material. Then, these loading conditions and material properties are input into the finite element analysis software, and the adjusted part model is solved. In finite element analysis, the actual structure is discretized into a finite number of small elements to approximately solve the numerical values of its stress and strain distributions for analysis. Finally, the stress-strain distribution of the part is obtained through finite element analysis, which can help engineers evaluate the strength and stability of the part under different working conditions, thereby guiding further improvement and optimization in the design, and also facilitating the analysis of the forces and applied forces on the parts actually produced according to the stress-strain data.

[0038] In one embodiment, if Figure 2 As shown, in step S20, the initial model of the part is adjusted according to the property parameters of the part to obtain the adjusted part model, which specifically includes: S21: Use the property parameters of the part to determine the dimensional data of the part during injection molding.
[0039] Specifically, the property parameters of the parts are predicted through mold flow analysis. In order to accurately obtain the dimensional data of the parts during injection molding, it is necessary to determine the size of the parts after injection molding based on the property parameters of the parts. The dimensional information including the length, width and height of the parts is obtained from the basic data of the parts to determine the dimensional data of the parts during injection molding, which helps to ensure that the parts obtain the required size and geometry during the injection molding process.
[0040] S22: According to the dimension data, an initial part model of the part is adjusted in the 3D simulation to obtain an adjusted part model.
[0041] Specifically, according to the previously determined part dimension data, including the dimension information of the length, width, and height of the part, the provided dimension data is imported into 3D simulation software, such as CAD software or other similar engineering design software. In the 3D simulation software, the standard part model is adjusted, and the dimensions of the part are adjusted according to the provided dimension data to achieve the size of the part in actual production and manufacturing. Using 3D simulation software for adjustment can make the design adjustment more accurate and efficient, avoid errors and waste that may occur in the actual manufacturing process, and ensure that the dimensions and geometric shapes of the part conform to the actual production effect.
[0042] In one embodiment, as Figure 3 shown, in step S30, that is, obtaining the stress-strain data of the adjusted part model, specifically including: S31: Obtain the applied loading conditions and the material properties of the part, and solve the adjusted part model through finite element analysis to obtain the stress-strain distribution of the part.
[0043] Specifically, first, it is necessary to obtain the loading conditions applied to the part, that is, the forces and pressures on the part in the actual use environment. At the same time, it is also necessary to understand the material properties of the part, including information such as the strength and elastic modulus of the material. Then, these loading conditions and material properties are input into the finite element analysis software to solve the adjusted part model. In finite element analysis, the actual structure is discretized into a finite number of small elements to approximately solve the numerical values of its stress and strain distributions for analysis. Finally, the stress-strain distribution of the part obtained through finite element analysis can help engineers evaluate the strength and stability of the part under different working conditions, thus guiding further improvement and optimization in the design, and also facilitating the analysis of the forces and applied forces on the parts actually produced based on the stress-strain data.
[0044] In one embodiment, as Figure 4 shown, in step S40, that is, obtaining the deformation displacement value of the part according to the stress-strain data and the material properties of the part, specifically including: S41: Determine the Young's modulus E of the part according to the material properties.
[0045] Specifically, by analyzing and testing the characteristics and properties of the material, the Young's modulus of the part when it is stressed is determined. Therefore, by determining the Young's modulus, the performance of the material can be better understood, so as to carry out reasonable design and material selection, ensure good stability and reliability of the part during use, and facilitate calculating the amount of deformation of the part when it is stressed based on the Young's modulus of the part.
[0046] S42: Through the formula: Calculate the displacement value of the part, where σ is the stress of the part, E is the Young's modulus of the part, and u is the deformation displacement of the part.
[0047] Specifically, the stress-strain data of the obtained parts is transmitted to the formula: for calculation to obtain the deformation value of the part after being stressed, that is, the deformation displacement value. After comparing the part after being stressed and deformed with the standard part, the position information of the abnormal deformation is analyzed, and the stress magnitude is recorded, which helps to accurately analyze the reason for the deformation of the part, and corresponding optimization processing can be carried out on the part processing according to this reason.
[0048] In one embodiment, as Figure 5 shown, in step S50, that is, the initial model of the part is correspondingly adjusted according to the displacement value to obtain the production model of the part, which specifically includes: S51: Compare the deformation displacement value of the part with a preset displacement threshold.
[0049] Specifically, by comparing the displacement value with the preset displacement threshold, it is possible to evaluate whether the deformation situation of the part meets the design requirements. When the displacement value does not match the preset displacement threshold, it may affect the stability, performance or reliability of the part. If the actual displacement value is less than or equal to the preset displacement threshold, it means that the part does not exceed the allowable displacement limit during stress or use. If the actual displacement value exceeds the preset displacement threshold, further analysis and adjustment of the design may be required, and corresponding measures need to be taken to improve the design or strengthen the part structure, so as to optimize the part model according to the displacement comparison result.
[0050] S52: When the deformation displacement value of the part exceeds the preset displacement threshold, obtain the displacement difference between the deformation displacement value of the part and the preset displacement threshold, and correspondingly adjust the initial model of the part according to the displacement difference to obtain the production model of the part.
[0051] Specifically, in the actual engineering or manufacturing process, if the measured displacement value of the part is greater than the preset displacement threshold, it means that the part may be deformed beyond the allowable range when loaded. Compare the displacement value with the preset displacement threshold, calculate the difference between the displacement value and the displacement threshold, that is, the displacement difference, and adjust the initial model of the part according to the displacement difference. The optimization measures include adjusting material selection, structural design, support method, etc., to reduce the displacement difference, improve the stability and performance of the part, understand the deformation situation of the part under stress, and take measures for the displacement difference exceeding the threshold to improve the design of the part, and finally obtain the production model of the part.
[0052] In one embodiment, as Figure 6 shown, this part deformation control method further includes: S61: Obtain and record the position information of each abnormal displacement.
[0053] Specifically, when the displacement value exceeds the preset range or expected value, it indicates that abnormal deformation or displacement has occurred in part of the structure of the part. Obtaining and recording the position information of the abnormal displacement helps technicians accurately identify the root cause of the problem and perform subsequent adjustments and optimizations, and helps further analyze and solve the problem of abnormal displacement.
[0054] S62: Generate an adjustment suggestion for the part according to the position information, and transmit the adjustment suggestion to the user terminal.
[0055] Specifically, during the process of recording the abnormal displacement, the specific position information of the occurrence of the abnormal displacement is obtained. These position information can provide the specific position and spatial coordinates of the part or structure under stress, deformation or displacement, and the position where the abnormal displacement appears in the part model can be analyzed, and corresponding adjustment suggestions can be put forward. The adjustment suggestions can be transmitted to the user terminal through information transmission technology. Transmitting to the user terminal enables relevant personnel to promptly grasp the situation of abnormal displacement, assisting them to better handle the problem and take corresponding measures.
