Description

Technical Field

[0001] The embodiments of the present application relate to the field of network technology, and in particular to a door panel installation gap control method, device and storage medium. Background Art

[0002] In the traditional structural design process, finite element simulation (FEA) is a bridge that connects the design stage with actual product testing. Finite element simulation uses computer-aided engineering (CAE) technology to evaluate the stress and deformation of the structure under specific load conditions without actually manufacturing and testing the product. This method not only speeds up the design and selection process of various prototypes, but also reduces design costs while improving product performance.

[0003] Especially in the structural design of energy storage containers, it is particularly important to accurately evaluate the installation gap of the door panels. In conventional finite element analysis, the door panels are usually not considered to have a supporting effect on the overall frame. In order to reduce the calculation scale of the model and shorten the R&D cycle, the door panels are not included in the model analysis of the overall system, but their strength is verified through a separate refined model. This approach usually leads to an inaccurate evaluation of the installation gap of the door panels because it does not take into account the actual deformation of the door panels as independent rigid bodies.

[0004] To solve this problem, this technology proposes a new evaluation technology by improving the finite element simulation calculation method. This technology can more accurately evaluate the installation gap of the door panel without adding additional simulation modeling and calculation time. This improvement not only improves the accuracy of the evaluation, but also provides an efficient and economical solution for solving problems in structural design. Summary of the invention

[0052] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0053] The term "multiple" as used herein refers to two or more than two. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the related objects are in an "or" relationship.

[0054] Example 1

[0055] Please refer to Figure 1 , Figure 1 A schematic flow chart of a door panel installation gap control method provided by an exemplary embodiment of the present application is shown.

[0056] The method is applicable to a container body and comprises the following steps.

[0057] Step 101, obtaining the model of the container body and the specification parameters of the door panel.

[0058] like Figure 2 As shown, for the convenience of calculation and verification, the numbers ①②③④⑤ in the figure are the serial numbers of the five battery compartment door panels of the energy storage box. The positions A, B, C, and D in the figure represent the four corners of each door frame; the numbers represent each door panel. The verification model in this verification is calculated and verified with the left side as the installation hinge.

[0059] Step 102: Establish a finite element analysis model of the container body according to the model of the container body and the specification parameters of the door panel.

[0060] Step 103, according to the transportation and use requirements, the boundary conditions of the finite element analysis model are set to perform finite element calculation and analysis.

[0061] Step 104, extracting the corner information of the door panel according to the finite element calculation results of the finite element analysis model.

[0062] Among them, the corner position information of the door panel includes the horizontal displacement and vertical displacement corresponding to the four corners of the door panel.

[0063] Step 105: Calculate the evaluated installation clearance of the door panel according to the corner position information of the door panel.

[0064] In a possible implementation manner, step 105 includes the following contents.

[0065] Content 1: In the finite element analysis model, obtain the first outer contour of the door panel before structural deformation and the second outer contour of the door panel after structural deformation. Among them, the four top corners of the first outer contour of the door panel are denoted as A, B, C, and D, and the four top corners of the second outer contour of the door panel after structural deformation are denoted as A', B', C', and D';

[0066] Content 2: Obtain the evaluated parameters of the door panel;

[0067] Content 3: Calculate the evaluated installation clearance of the door panel according to the gap design requirements and the evaluated parameters of the door panel.

[0068] Among them, the evaluated parameters include the vertical displacement of the right side relative to the left side, the horizontal displacements of corners A and B of the door panel, the vertical displacements of corners A, B, C, and D of the door panel, the gap of the upper edge of the door panel before deformation, the gap of the lower edge of the door panel before deformation, the gap of the upper edge of the door panel after deformation, the gap of the lower edge of the door panel after deformation, the vertical displacement of the upper right corner of the door panel, the vertical displacement of the lower right corner of the door panel, the width and height of the door panel.

[0069] Among them, the gap design requirements are:

[0070] That is, l upper > Lyc - PC'.................................. (1);

[0071] l lower > QD' - Lyd.............................. (2).

[0072] Combined with Figure 6 to Figure 7 as shown, an example is given for the above calculation process.

[0073] The yellow frame ABCD is the outer contour of the door panel before structural deformation, the blue frame A'B'C'D' is the outer contour of the door panel after structural deformation, and the left side AB is the axis where the door hinge is located.

[0074] Δy: The vertical displacement of the right side of the door panel relative to the left side;

[0075] Lxa, Lxb: The horizontal displacements of corners A and B of the door panel;

[0076] Lya, Lyb, Lyc, Lyd: The vertical displacements of corners A, B, C, and D of the door panel;

[0077] e upper: Clearance of the upper edge of the door panel before deformation;

[0078] e lower: Clearance of the lower edge of the door panel before deformation;

[0079] e upper': Clearance of the upper edge of the door panel after deformation;

[0080] e lower': Clearance of the lower edge of the door panel after deformation;

[0081] PC': Vertical displacement of the upper right corner of the door panel;

[0082] QD': Vertical displacement of the lower right corner of the door panel;

[0083] W: Width of the door panel;

[0084] H: Height of the door panel.

[0085] According to the design requirements, under the test conditions specified in the standard ISO 1496-1, it is necessary to ensure that the clearance between the deformed door panel and the frame is greater than 0, that is, the upper edge clearance e upper' > 0 and the lower edge clearance e lower' > 0. The hoisting condition with a simulated weight of 2 times the full-load container weight is the most severe condition for the deformation of the door panel. Therefore, this condition is taken as an example in the calculation to calculate the actual installation clearance required for the door panel.

[0086] According to the clearance control requirements between the door frame and the door panel:

[0087] e upper' = e upper + PC' - Lyc > 0

[0088] That is, l upper > Lyc - PC' ……………………………………(1)

[0089] e lower' = l lower + Lyd - QD' > 0

[0090] That is, l lower > QD' - Lyd ………………………………(2)

[0091] The following is the calculation process.

[0092] It can be known that right triangle △A'B'M ∼ right triangle △B'C'N

[0093] ∴ (C^′N) / (MB^′) = (B^′C)^′ / (A^′B^′)

[0094] Δy / (|Lxa - Lxb|) = W / H

[0095] Δy = (W / H) * |Lxa - Lxb| …………………(3)

[0096] ∴ Equation (1) can be changed to:

[0097] l upper>Lyc - (C’N + Lyb) = Lyc - (Δy + Lyb) ……………………………(4)

[0098] Also, because triangle △B’C’N ≌ △A’D’O

[0099] ∴ OD’ = C’N = Δy

[0100] ∴ Equation (2) can be transformed into:

[0101] l lower>(Lya + D’O) - Lyd = (Lya + Δy) - Lyd …………………………(5)

[0102] The vertical displacement amounts Lxa, Lya, Lxb, Lyb, Lyc, and Lyd of the four corners of the door frame before and after structural deformation can all be directly extracted from the results of the finite element simulation calculation.

[0103] Step 106, under the evaluation and installation gap requirements of the door panel, evaluate and adjust the actual installation gap of the door panel.

[0104] Based on the above example, the following conclusions can be obtained.

[0105] For door frame ①, it is known that W = 835 mm, H = 2530 mm, Lxa = 9.4 mm, Lya = 8.2 mm, Lxb = 1.7 mm, Lyb = 8.1 mm, Lyc = Lyb of door frame ② = 13.2 mm, Lyd = Lya of door frame ② = 13.2 mm;

[0106] Therefore, according to Equation (3), it can be known that Δy = 2.54 mm. According to Equation (4), it can be known that the upper edge gap needs to be controlled above 2.56 mm. According to Equation (5), it can be known that the lower edge gap should be controlled above -2.46 mm.

[0107] That is, when the result is negative, it indicates that the gap between the door panel and the frame will increase under this working condition. Therefore, there is no need to control the installation gap.

[0108] Similarly, it can be obtained that the upper edge gap of door frame ② needs to be controlled above -0.64 mm, and the lower edge gap needs to be controlled above 0.74 mm; the upper edge gap of door frame ③ needs to be controlled above -5.17 mm, and the lower edge gap needs to be controlled above 5.17 mm; the upper edge gap of door frame ④ needs to be controlled above -9.40 mm, and the lower edge gap needs to be controlled above 9.10 mm; the upper edge gap of door frame ⑤ needs to be controlled above -9.77 mm, and the lower edge gap needs to be controlled above 9.77 mm.

[0109] From the calculation results, it can be seen that the upper edge installation gaps of door frames ②③④⑤ do not need to be considered.

[0110] Therefore, for this container body, without considering the installation tolerance, the upper edge gap of the door panel during installation must be controlled at more than 2.56mm, and the lower edge gap must be controlled at more than 9.77mm. Combined with actual production, the upper edge gap is controlled to 3mm, and the lower edge gap is controlled to 10mm.

[0111] In summary, in this patent, the model of the container body to be evaluated and the parameters such as the dimensions of the battery compartment door are obtained; a finite element analysis model of the container body is established, and appropriate boundary conditions are added to the model according to the requirements of actual transportation and use; finite element calculation and analysis are performed; the lateral displacement and vertical vector of the four corners of each door frame are extracted according to the calculation results; calculations are performed according to the newly proposed door panel installation gap evaluation method to evaluate the required gap for door panel installation; it is determined whether the actual design and installation can meet the requirements; if not, the box structure is optimized and then the calculation is repeated; if so, the evaluation results are output. Evaluating the installation gap of the container door panel through this process can provide more rigorous calculation results and improve the safety of structural use.

[0112] Example 2

[0113] Before step 102, the model is also pre-processed.

[0114] Specifically, the initial three-dimensional model is processed with mid-surface extraction and connection relationship processing. The connection relationship processing includes connecting the concentrated mass point simulating the large mass equipment to the installation position through the flexible unit for simulating the large mass equipment. The initial three-dimensional model uses 8mm*8mm shell units to simulate the main structure of the model, and the main structure of the model is the main frame of the container. For example, the concentrated mass point mass unit and the rbe3 flexible unit are combined to simulate large mass equipment such as battery modules and water machines.

[0115] In a possible implementation, Figure 3 As shown in the figure, when performing finite element analysis, the simplified three-dimensional model is processed by extracting the middle surface and the connection relationship, and the concentrated mass point simulating the large mass equipment is connected to the installation position through a flexible unit to simulate the equipment. The overall model is simulated using 8mm*8mm shell units. After the model is established, rigid unit hoisting ropes are added to the four top corners, and constraints are applied. The model is counterweighted to 2R-T (R=38000kg, T=8000kg), and 1 times the gravity acceleration is applied to the entire system model to simulate the container body hoisting condition.

[0116] In addition, during the modeling process, if Figure 3As shown, the top corner fittings are also simulated with solid meshes, and the corner weld positions are connected using node coupling. Weld unit simulation connections are established at the lap weld positions, seam units are established at the key weld positions to simulate the key welds, and binding relationships are established between the connections of solid units and shell units by establishing node to surface binding connections. Contact pair friction contacts are established between components with friction contacts, and the bolted connections are simulated by combining washer units with rbe2 rigid units.

[0117] Furthermore, different unit properties are assigned to different components of the model, including material properties, unit thickness, etc., and boundary conditions of specific analysis conditions are applied to the model. Displacement constraints are restricted at the positions of the four top corner pieces, and 2 times the gravitational acceleration is applied to the entire model.

[0118] like Figure 4 As shown, from the cloud diagram of the simulation results of the energy storage container body hoisting, it can be seen that the lateral displacements of the four corners of the door frame are: door frame ① Lxa = 9.4mm, Lxb = 1.7mm;

[0119] Door frame②Lxa=9.6mm,Lxb=1.6mm;

[0120] Door frame ③Lxa=10.1mm,Lxb=1.4mm;

[0121] Door frame④Lxa=10.6mm,Lxb=1.2mm;

[0122] Door frame⑤Lxa=10.9mm,Lxb=1.0mm.

[0123] like Figure 5 As shown in the figure, from the cloud diagram of the simulation results of the energy storage container hoisting, it can be seen that the vertical displacements of the four corners of the door frame are:

[0124] Door frame①Lya=8.2mm,Lyb=8.1mm;

[0125] Door frame②Lya=13.2mm,Lyb=13.2mm;

[0126] Door frame ③Lya=15.1mm,Lyb=15.2mm;

[0127] Door frame④Lya=12.8mm,Lyb=12.9mm;

[0128] Door frame⑤Lya=6.8mm,Lyb=6.6mm.

[0129] This application also provides an experimental verification process. Figure 8 Provides a container body frame line drawing, Fig. 9Provides a plot of test deflection measurements. Fig.10 Provides screenshots of experimental results. Fig. 9 It can be seen from the figure that marked point 2 is point A3 of door frame ③ in the "Door Panel Numbering Description Diagram". From the test result diagram, it can be seen that the vertical displacement of this point under the 2R-T hoisting condition is 15mm (that is, during the lifting process), and the simulation calculation result is 15.1mm. Therefore, it can be considered that the calculation results of the simulation model are reliable.

[0130] Example 3

[0131] After step 102, the process also includes simulating the lifting condition.

[0132] In response to the completion of the establishment of the finite element analysis model, rigid units are added to the four top corner pieces of the container body in the simulation scene to simulate the ropes and apply constraints. In the simulation scene, the lifting condition of the container body is simulated.

[0133] For the simulation of the hoisting condition, in a possible implementation, the counterweight of the container body in the finite element analysis model is adjusted to the simulated weight and 1 times the gravity acceleration is applied to the container body.

[0134] In summary, it also provides Fig.11 It is used to provide the execution logic diagram of the above-mentioned entire door panel installation gap control method and the content of pre-processing of the finite element analysis model.
