[0037] The following will be combined with the embodiments and drawings to clearly and completely describe the concept, specific structure and technical effects disclosed in the present invention, so as to fully understand the purpose, scheme and effect disclosed in the present invention. It should be noted that the embodiments and features in the embodiments in this application can be combined with each other without conflict.
[0038] refer to Figure 1 ,like Figure 1 A beam plate reinforcement design method provided by an embodiment of the present invention is shown, and the method comprises the following steps:
[0039] S100, obtaining initial design parameters and material properties of the cross beam plate, using finite element software to simulate and analyze the cross beam plate, and predicting process parameters; the process parameters include curvature, perimeter change rate, deformation amount, and crack amount;
[0040] S200, adjusting the initial design parameters according to the process parameters to obtain optimized design parameters;
[0041] S300, generating a reinforced structure model based on the optimized design parameters, performing secondary simulation analysis on the reinforced structure model using finite element software, verifying its structural strength and stability, and obtaining an optimal reinforced structure model;
[0042] S400: Outputting a processing plan for the crossbeam plate reinforcement design according to the preferred reinforcement structure model.
[0043] The present invention significantly improves design accuracy and production efficiency by automatically optimizing process parameters, ensuring stable performance of the beam plate and controllable costs, and completely changing the traditional inefficient model that relies on manual experience. By performing multi-parameter collaborative optimization on the beam plate reinforcement design and adjusting the reinforcement structure model in real time, the optimal balance between structural strength and lightweight is achieved, which significantly reduces material loss, improves design efficiency, and shortens production cycles. At the same time, the systematic design process effectively reduces human errors and improves product quality consistency.
[0044] As an improvement of the above embodiment, in S100, the initial design parameters and material properties of the beam plate are obtained, and the beam plate is simulated and analyzed using finite element software to predict the process parameters, including:
[0045] S110, vertically slicing the beam plate along the stamping direction to obtain a plurality of slicing regions;
[0046] S120, applying corresponding processing parameters to each of the slicing areas respectively, using finite element software to simulate and analyze the slicing areas, and predicting process parameters; the processing parameters include variable pressure edge force, die gap, stamping speed and friction coefficient.
[0047] Specifically, when adjusting the initial design parameters, a multi-objective optimization algorithm is used to comprehensively consider structural strength, weight and cost to ensure that the optimization results are globally optimal. The adjusted design parameters are verified through iterations to further refine the model and improve design reliability.
[0048] As an improvement of the above embodiment, in S200, adjusting the initial design parameters according to the process parameters to obtain optimized design parameters includes:
[0049] S210, obtaining a process parameter and a corresponding standard process threshold value for each of the slicing regions;
[0050] S220, determining the deviation between the process parameter and the corresponding standard process threshold, and arranging each of the slicing regions in descending order based on the deviation;
[0051] S230, preferentially adjusting the design parameters of the slice area with a larger deviation, and determining that the balance degree of the overall structure is greater than the balance degree threshold;
[0052] S240, synthesizing the adjustment results of each slice region to generate global optimization design parameters.
[0053] Through this refined adjustment, the performance of each slice area is ensured to be optimal, thereby improving the structural stability and service life of the overall beam plate, achieving a deep integration of design and manufacturing, further reducing production costs and improving product competitiveness.
[0054] As an improvement of the above embodiment, in S230, the step of preferentially adjusting the design parameters of the slice area with a larger deviation, and determining that the balance degree of the overall structure is greater than the balance degree threshold, includes:
[0055] S231, determining whether the slicing area with a larger deviation is located at the edge of the beam plate; if the slicing area is located at the edge of the beam plate, executing S232; otherwise, executing S233;
[0056] S232, after bending the slice area located at the edge, execute S233;
[0057] Additional bending can be used to strengthen the deformation resistance.
[0058] S233, determining whether the slice area with a large deviation is located in the stress concentration area of the beam plate, if it is located in the stress concentration area, strengthening the local structure of the slice area and updating the design parameters of the beam plate; if it is not the stress concentration area, optimizing the material strength of the connection and updating the design parameters of the beam plate;
[0059] Specifically, for the slicing area in the stress concentration zone, high-strength materials are used for local reinforcement to ensure that the connection is stable and reliable, further improve the fatigue resistance of the beam plate, and extend the service life. Through precise adjustment, the performance of each slicing area is ensured to be optimal, the overall structure of the beam plate is stable, the service life is extended, and the production cost is reduced. For the slicing area in the non-stress concentration area, the material strength of the connection is optimized, and tough materials are used to improve the crack resistance, ensure the overall structure is coordinated, further reduce maintenance costs, and enhance product market competitiveness. Through this meticulous optimization strategy, not only the mechanical properties of the beam plate are improved, but also the production efficiency is significantly improved, ensuring the stability and reliability of product quality.
[0060] S234, using finite element analysis software to simulate the stress distribution of each test point in the optimized beam plate, determine the balance of the overall structure based on the stress distribution of each test point, and determine whether the balance of the overall structure is greater than the balance threshold. If so, end; if not, execute S233.
[0061] By integrating the adjustment results of each area, we ensure that the overall structural balance exceeds the preset threshold, and finally achieve an optimal balance between the performance and cost of the beam plate. Through the above-mentioned refined zoning adjustment, the finite element analysis software is used to simulate the stress distribution under different working conditions and identify key weak areas. According to the simulation results, the beam plate is partitioned and designed, and the material ratio and structural parameters of each area are optimized. The performance of each area of the beam plate is significantly improved, and the overall structural balance is greatly improved, ensuring that it can still maintain excellent performance under extreme conditions and extend its service life.
[0062] As an improvement of the above embodiment, in S300, the generation of a reinforced structure model based on the optimized design parameters, the use of finite element software to perform secondary simulation analysis on the reinforced structure model, verifying its structural strength and stability, and obtaining a preferred reinforced structure model, includes:
[0063] S310, constructing a three-dimensional model of the beam plate according to the updated design parameters of the beam plate, marking the material and structural parameters of each slice area, and generating a reinforced structural model;
[0064] S320, finite element analysis of the reinforced structure model to evaluate its stress distribution and deformation under different working conditions;
[0065] S330, fine-tuning the reinforced structure model according to the stress distribution and deformation degree under different working conditions until the structural strength and stability meet the design requirements, thereby obtaining an optimal reinforced structure model.
[0066] According to the marked structural parameters, the stress distribution in each area is accurately simulated to ensure that the model is consistent with the actual situation; based on the simulation results, the structural details are adjusted and strengthened, the material distribution is optimized, and the overall bearing capacity is improved; the stability of the model under different working conditions is verified; the effectiveness of the design parameters is ensured, and finally the optimal strengthened structural model is generated.
[0067] As an improvement of the above embodiment, in S400, the step of outputting a processing scheme for the cross beam plate according to the preferred reinforced structure model includes:
[0068] According to the preferred reinforced structure model, the material cutting range and welding process parameters of each slicing area are determined, and the material thickness and welding position of each slicing area are marked, and the processing drawings of the beam plate are output.
[0069] Through the above steps, the crossbeam plate processing process can be made efficient and accurate, achieving the best balance between performance and cost, and improving the overall structural stability and service life.
[0070] In the specific implementation method, the basic data of the beam plate, including material properties and geometric dimensions, is first collected, and data analysis and modeling are performed using finite element software. Finite element software such as Dynaform is used for simulation analysis to predict possible problems in the forming process, such as wrinkling or cracking, and the design is optimized accordingly. The design parameters are adjusted according to the simulation results to optimize the beam plate structure and improve its bearing capacity and structural stability. The optimal design solution is generated. The production line parameters are then adjusted to ensure that the actual production is highly consistent with the design solution, and ultimately the efficient and precise manufacturing of the beam plate is achieved.
[0071] The bearing capacity and service life of the cross beam plate are significantly improved, while the production cost and maintenance difficulty are reduced. The present invention not only improves the bearing capacity of the cross beam plate, but also significantly reduces the production cost, thus achieving a combination of high efficiency and economy of the design.
[0072] Not only does it improve design accuracy, but it also ensures the stability and consistency of the production process by real-time monitoring of the production process and adjusting process parameters in real time, further reducing the scrap rate and improving product quality. Through data-driven intelligent optimization, the beam plate design achieves a perfect balance between structural strength and lightness.

[0074] at least one processor;
[0075] at least one memory for storing at least one program;
