Description

Technical Field

[0001] This invention relates to the field of finite element modeling and analysis technology, specifically to a method, apparatus, and storage medium for establishing a model of a closely spaced ribbed steel plate structure. Background Technology

[0002] In the nuclear power sector, reinforced concrete structures are commonly used in nuclear safety-related buildings. However, concrete structures are heavy, have poor ductility, and their construction quality is difficult to guarantee. In contrast, steel structures are lighter, stronger, more ductile, easier to modularize, and can be constructed using prefabricated methods, which helps ensure processing quality, is largely unaffected by natural conditions, and allows for a high degree of mechanization in production and installation. Therefore, a ribbed double-plate all-steel structure is being explored for nuclear safety-related buildings. Due to the complexity of nuclear power plant structural configurations and ribbed double-plate designs, there is currently no dedicated modeling and analysis software; modeling and analysis must rely on general-purpose finite element software (such as ANSYS or ABAQUS).

[0003] In existing technologies, general-purpose finite element software (such as ANSYS or ABAQUS) lacks built-in section properties to describe the cross-sectional configuration of double-plate stiffeners. It can only achieve this by separately modeling the upper and lower plates and the intermediate stiffeners and then bonding them together. Since the nodes of the upper and lower plates and the intermediate stiffeners may not correspond one-to-one, coupling is required for connection. Unlike civil buildings, the wall layouts on different floors of nuclear power plants are not entirely the same, and there are no standard floors. Typically, the wall positions of upper and lower floors in a nuclear power plant are not one-to-one, leading to wall misalignment, disappearance, or addition. For walls with double-plate stiffeners, this situation is even more complex, as discontinuous wall lines prevent the upper and lower floors from sharing nodes. Because both walls and plates are double-plate stiffeners, modeling the joint nodes between walls and plates is even more complex, making it almost impossible to coordinate the positioning of the steel plates in both the wall and plate, again requiring coupling. The aforementioned requirement for coupled modeling results in a large number of constraint equations in the finite element model, leading to slow solution speed and affecting the analysis progress.

[0004] In addition, if the stiffening ribs are ignored in the modeling and the stiffening ribs are formed by connecting the nodes of the steel plates on both sides, the stiffening ribs may be deflected and inconsistent with the horizontal X and Y directions in the design, which will change the force transmission path and affect the accuracy of the analysis. Sometimes, the direction of the stiffening ribs in the floor slab also needs to be flexibly changed according to the design of one-way or two-way slabs, which further increases the difficulty of modeling the stiffening ribs of the floor slab.

[0005] To address the aforementioned technical problems, existing technologies, such as CN103353906B, disclose a method for analyzing the stress and deformation of a turntable surface. First, based on the turntable entity, data measurements of the surface are performed. Then, based on the measured surface data, a parametric geometric model of the turntable surface is established using the CAD software Pro / ENGINEER. This parametric geometric model is saved as an IGES format file. The IGES format file is imported into the CAE software ANSYS, and relevant attribute parameters are set. The parametric geometric model of the turntable is meshed in the CAE software. Constraints and loads are set and applied in the CAE software according to the actual working conditions of the turntable surface. Finally, the solution is calculated in the CAE software, and the analysis results are observed.

[0006] However, existing technical solutions have not completely solved the above-mentioned technical problems. Summary of the Invention

[0007] To address the aforementioned technical problems, this invention proposes a method, apparatus, and storage medium for establishing a model of a closely spaced ribbed steel plate structure.

[0008] To achieve the above objectives, this invention proposes a method for establishing a model of a closely spaced ribbed steel plate structure, comprising: generating planar position projection diagrams of structural components of each layer based on the closely spaced ribbed steel plate structure; establishing planar projection diagrams of stiffening ribs based on the planar position projection diagrams; and generating a finite element three-dimensional geometric model based on the planar projection diagrams of stiffening ribs.

[0009] Furthermore, generating planar position projection diagrams of structural components of each layer based on the ribbed steel plate structure includes: projecting the two-dimensional planar diagrams of each layer of the ribbed steel plate structure onto a horizontal plane to generate preliminary position projection diagrams; and establishing the planar position projection diagrams based on the preliminary position projection diagrams.

[0010] Furthermore, establishing the planar position projection map based on the preliminary position projection map includes: adjusting the upper wall, which is inconsistent with the thickness of the lower wall in the preliminary position projection map, to be consistent with the thickness of the lower wall, in order to establish the planar position projection map.

[0011] Furthermore, establishing the planar position projection map based on the preliminary position projection map further includes: adjusting an upper wall that deviates less than a deviation threshold from the wall line of the lower wall in the preliminary position projection map to the same position as the lower wall, thereby establishing the planar position projection map.

[0012] Furthermore, establishing a stiffening rib planar projection diagram based on the planar position projection diagram includes: arranging the stiffening ribs at equal intervals in the wall of the planar position projection diagram to establish the stiffening rib planar projection diagram.

[0013] Furthermore, the structural component also includes a floor slab. Based on the planar position projection diagram, a planar projection diagram of the stiffening rib is established, which further includes: the floor slab is a one-way slab, and the extension direction of the stiffening rib is parallel to the short side direction of the floor slab.

[0014] Furthermore, generating a finite element three-dimensional geometric model based on the stiffening rib planar projection diagram includes using Boolean operations to divide the lines in the stiffening rib planar projection diagram at their intersection points to establish the finite element three-dimensional geometric model.

[0015] Furthermore, generating a finite element three-dimensional geometric model based on the stiffening rib planar projection diagram also includes generating a stiffening rib planar projection reference plane based on the stiffening rib planar projection diagram; and generating the finite element three-dimensional geometric model based on the stiffening rib planar projection reference plane.

[0016] Furthermore, generating the finite element three-dimensional geometric model based on the stiffening rib plane projection reference plane includes dividing the stiffening rib plane projection reference plane into multiple sub-reference planes; and generating the finite element three-dimensional geometric model based on the multiple sub-reference planes.

[0017] Furthermore, generating the finite element three-dimensional geometric model based on the plurality of sub-reference planes includes adjusting the vertical position of the plurality of sub-reference planes to generate an initial three-dimensional geometric model; and generating the finite element three-dimensional geometric model based on the initial three-dimensional geometric model.

[0018] To achieve the above objectives, the present invention also proposes a model-building device for a closely spaced ribbed steel plate structure, comprising: The first projection drawing creation module is used to generate planar position projection drawings of structural components in each layer based on the ribbed steel plate structure. The second projection diagram creation module is used to create a stiffening rib planar projection diagram based on the planar position projection diagram. The model building module is used to generate a finite element three-dimensional geometric model based on the plane projection of the stiffening rib.

[0019] To achieve the above objectives, the present invention also proposes a computer-readable storage medium comprising a stored computer program, wherein the computer program can be executed by an electronic device to describe the method.

[0020] To achieve the above objectives, the present invention also provides a computer program product, comprising a computer program that, when executed by a processor, implements the steps of the method.

[0021] To achieve the above objectives, the present invention also proposes an electronic device, including a memory and a processor, wherein the memory stores a computer program and the processor is configured to execute the method described by the computer program.

[0022] Based on the above technical solution, the present invention has at least the following beneficial effects: 1. The model establishment method for the closely ribbed steel plate structure proposed in this invention establishes a planar projection of the stiffening ribs and then imports it into finite element software to establish a finite element three-dimensional geometric model. This avoids directly establishing the finite element three-dimensional geometric model by using a coupling method in the finite element software, thereby improving the solution speed of the finite element software.

[0023] 2. The modeling method for the densely ribbed steel plate structure proposed in this invention makes full use of the geometric data interface, surface dragging, volume separation, and working plane cutting of the finite element software to establish the finite element three-dimensional geometric model, thereby improving the modeling speed.

[0024] 3. The model establishment method of the closely ribbed steel plate structure proposed in this invention not only ensures that the floor slab stiffening ribs are always collinearly connected with the floor slab and wall stiffening ribs to achieve accurate force direction, but also allows the floor slab stiffening ribs to be adjusted according to the actual force conditions of the floor slab.

Detailed Implementation

[0026] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0027] The present invention will be further described in detail below with reference to specific embodiments, which should not be construed as limiting the scope of protection claimed by the present invention.

[0028] Example

[0029] To address the aforementioned technical problems, this invention proposes a method, apparatus, and storage medium for establishing a model of a closely spaced ribbed steel plate structure.

[0030] According to one aspect of the embodiments of this application, a method for modeling a closely spaced ribbed steel plate structure is provided, such as... Figure 1 As shown, it includes the following steps: S1, Based on the densely ribbed steel plate structure, generate a planar position projection diagram of each layer of structural components.

[0031] Furthermore, generating planar position projection diagrams of structural components of each layer based on the ribbed steel plate structure includes projecting the two-dimensional planar diagrams of each layer of the ribbed steel plate structure onto a horizontal plane to generate preliminary position projection diagrams; and establishing the planar position projection diagrams based on the preliminary position projection diagrams.

[0032] Furthermore, establishing the planar position projection map based on the preliminary position projection map includes: adjusting an upper wall with a thickness inconsistent with the lower wall in the preliminary position projection map to have a thickness consistent with the lower wall, thereby establishing the planar position projection map; and adjusting an upper wall with a wall line deviating less than a deviation threshold from the lower wall in the preliminary position projection map to the same position as the lower wall, thereby establishing the planar position projection map.

[0033] It should be noted that the planar position projection drawing refers to a planar drawing obtained by projecting the outlines of each layer of structural components onto the same horizontal plane, used to reflect the horizontal position and outline of each layer of structural components. The preliminary position projection drawing refers to a planar drawing in which the outlines of each layer of structural components are projected onto the same horizontal plane without modifying the position of each layer of structural components. The structural components of each layer include walls, floors, and beams. In some embodiments, the structural components of each layer consist of walls, floors, and beams.

[0034] It should also be noted that the deviation threshold is 0mm-300mm. In this embodiment, the deviation threshold is 200mm. In other embodiments, the deviation threshold may also be 50mm, 100mm, 150mm, 250mm, and 300mm, etc.

[0035] Specifically, the positions and outlines of structural members in each layer of the ribbed steel plate structure are not all the same. The outlines of the structural members in the planar projection drawings of each single-layer stiffening rib are projected layer by layer along the height direction from bottom to top onto the first-floor plan, obtaining preliminary position projection drawings. Further, the preliminary position projection drawings are adjusted layer by layer using the aforementioned method to align the wall lines of all layers and maintain consistent thickness, ultimately generating a planar position projection drawing, such as... Figure 2 As shown.

[0036] Optionally, the drawing software used is AutoCAD; the ribbed steel plate structure is a double-ribbed steel plate structure.

[0037] S2, Based on the planar position projection diagram, establish the stiffening rib planar projection diagram.

[0038] Furthermore, establishing a stiffening rib planar projection diagram based on the planar position projection diagram includes: arranging the stiffening ribs at equal intervals in the wall of the planar position projection diagram to establish the stiffening rib planar projection diagram.

[0039] Furthermore, the structural component also includes a floor slab. Based on the planar position projection diagram, a planar projection diagram of the stiffening rib is established. The stiffening rib is a one-way slab, and the extension direction of the stiffening rib is parallel to the short side direction of the floor slab.

[0040] It should be noted here that the stiffening rib planar projection view refers to the planar view showing the position of the ribs in each layer of the structural components.

[0041] In this embodiment, the stiffening ribs in the planar projection of the stiffening ribs are only arranged in the wall; the stiffening ribs in the floor slab will be added after importing the data into the finite element software. Specifically, both the wall and the floor slab are closely ribbed double steel plate structures, with the stiffening ribs arranged between the two steel plates.

[0042] In other embodiments, the stiffening ribs in the planar projection of the stiffening ribs may also be arranged in walls and floors.

[0043] Specifically, such as Figure 3 As shown, when arranging stiffening ribs in the wall of the planar projection, the principle that the floor slab is a one-way slab must be met to facilitate the batch generation of stiffening ribs in the wall during subsequent finite element 3D geometric modeling. Then, in the drawing software, the outermost wall axis of the stiffening rib planar projection is selected, and the entire stiffening rib planar projection is generated as a surface region. The processed stiffening rib planar projection is then exported as an iges file. Subsequently, the iges file is imported into the finite element software, generating points, lines, and surfaces on the XY plane from the two-dimensional stiffening rib planar projection, preparing for subsequent finite element 3D geometric modeling.

[0044] S3, Generate a finite element three-dimensional geometric model based on the plane projection of the stiffening rib.

[0045] Further, generating a finite element three-dimensional geometric model based on the stiffening rib planar projection diagram includes: using Boolean operations to divide the lines in the stiffening rib planar projection diagram at their intersection points to establish the finite element three-dimensional geometric model; generating a stiffening rib planar projection reference plane based on the stiffening rib planar projection diagram; and generating the finite element three-dimensional geometric model based on the stiffening rib planar projection reference plane.

[0046] It should be noted that in some embodiments, after the stiffening rib planar projection is imported into the finite element software, the stiffening rib planar projection consists of some independent lines. By establishing a stiffening rib planar projection reference plane, these lines are contained in one plane, that is, all the lines are turned into a whole.

[0047] Furthermore, generating the finite element three-dimensional geometric model based on the stiffening rib plane projection reference plane includes dividing the stiffening rib plane projection reference plane into multiple sub-reference planes; and generating the finite element three-dimensional geometric model based on the multiple sub-reference planes.

[0048] In this embodiment, as Figure 4 As shown, Boolean overlap operations are used to divide the lines in the plane projection of the stiffening rib at the intersection points, and then the "surface subtraction line" function in the finite element software is used to divide the plane projection reference plane of the stiffening rib into multiple sub-reference planes.

[0049] In other embodiments, Boolean bonding operations can also be used to divide the lines in the planar projection of the stiffening rib at their intersections.

[0050] Furthermore, the finite element three-dimensional geometric model is generated based on the multiple sub-reference planes, including adjusting the vertical position of the multiple sub-reference planes to generate an initial three-dimensional geometric model; and generating the finite element three-dimensional geometric model based on the initial three-dimensional geometric model.

[0051] It should be noted that the walls of the initial three-dimensional geometric model are solid.

[0052] like Figure 5 As shown, the "Drag and Drop to Form a Solid" function of the finite element software is used to adjust the vertical positions of multiple sub-reference planes to generate an initial three-dimensional geometric model. Specifically, the selected sub-reference plane is dragged from the bottom layer along the height direction until it reaches the roof height, generating an initial three-dimensional geometric model that includes all walls. This step ensures that the initial three-dimensional geometric model correctly reflects the spatial structure of the factory building.

[0053] like Figure 6As shown, based on the elevation and thickness of each floor slab, the elevations of the upper and lower steel plates of each floor slab are calculated. In the finite element software, the working plane is set to be parallel to the XY plane, and the elevation of each steel plate is used as the Z coordinate of the working plane. Using the "working plane cutting volume" function in the finite element software, the initial three-dimensional geometric model is cut layer by layer with the working plane to batch create the floor slabs of each floor. Then, based on the two-dimensional plan view of each layer of the ribbed steel plate structure, unnecessary geometric information in the generated model is deleted, while the geometric information of the factory wall panels and wall stiffening ribs is retained to generate a finite element three-dimensional geometric model that does not include the floor slab stiffening ribs.

[0054] Finally, as Figure 7 As shown, the model is inspected room by room. Based on the actual stress of the floor slab, the positioning points of the wall stiffening ribs are selected and connected to form the stiffening ribs in the floor slab. Finally, a finite element three-dimensional geometric model containing the floor slab stiffening ribs is generated.

[0055] Optionally, the finite element software used is ANSYS.

[0056] It should be noted that, for the sake of simplicity, the foregoing method embodiments are all described as a series of actions. However, those skilled in the art should understand that this application is not limited to the described order of actions, as some steps may be performed in other orders or simultaneously according to this application. Furthermore, those skilled in the art should also understand that the embodiments described in the specification are preferred embodiments, and the actions and modules involved are not necessarily essential to this application.

Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.

[0097] In summary, as can be seen from the above description, the embodiments of the present invention achieve the following technical effects: 1. The model establishment method for the closely ribbed steel plate structure proposed in this invention establishes a planar projection of the stiffening ribs and then imports it into finite element software to establish a finite element three-dimensional geometric model. This avoids directly establishing the finite element three-dimensional geometric model by using a coupling method in the finite element software, thereby improving the solution speed of the finite element software.

[0098] 2. The modeling method for the densely ribbed steel plate structure proposed in this invention makes full use of the geometric data interface, surface dragging, volume separation, and working plane cutting of the finite element software to establish the finite element three-dimensional geometric model, thereby improving the modeling speed.

[0099] 3. The model establishment method of the closely ribbed steel plate structure proposed in this invention not only ensures that the floor slab stiffening ribs are always collinearly connected with the floor slab and wall stiffening ribs to achieve accurate force direction, but also allows the floor slab stiffening ribs to be adjusted according to the actual force conditions of the floor slab.
