Description

Technical Field

[0001] This application relates to the field of structural design, and in particular to a method, apparatus, equipment and medium for determining a weld-free and bolt-free metal tenon and mortise structure. Background Technology

[0002] Metal structures, with their advantages of high strength, good plasticity, and convenient construction, have been widely used in fields such as building engineering and sheet metal machinery and equipment (such as automobiles and industrial equipment), becoming one of the core structural forms in modern engineering construction.

[0003] Currently, the connection of metal structural components mainly relies on two traditional methods: welding and stud / anchor connections. While these methods are mature in engineering practice, they both have inherent technical drawbacks. In welding, the ultimate strength of the welded joint is far lower than that of the base metal material itself, limiting the overall structural stiffness and load-bearing capacity. Stud / anchor connections are separate connections, prone to breakage / loosening under dynamic loads, and require drilling that damages the base material. In contrast, using weld-free and stud-free metal tenon and mortise structures allows the connection to be seamlessly integrated with the overall structure. Under loads such as collisions, earthquakes, and typhoons, the connection becomes increasingly tighter, ensuring the overall strength and stiffness of the sheet metal equipment / building.

[0004] However, there is currently no universal design and verification method for weld-free and stud-free metal tenon and mortise structures for nodes, making it difficult to apply weld-free and stud-free metal tenon and mortise structures to various metal structures. Summary of the Invention

[0005] The purpose of this application is to provide a method, apparatus, equipment and medium for determining weld-free and stud-free metal tenon and mortise structures, which can realize the weld-free and stud-free metal tenon and mortise design and verification of internal nodes of metal structures, so that weld-free and stud-free metal tenon and mortise structures can be applied to various metal structures.

[0006] To achieve the above objectives, this application provides the following solution: In a first aspect, this application provides a method for determining a weld-free and bolt-free metal tenon and mortise structure, including: Obtain a 3D overall model of the target structure that conforms to the target design specifications. The 3D overall model contains stress information. Based on the component connection nodes and multiple preset weldless and studless metal tenon and mortise structures in the 3D overall model, determine the 3D node models corresponding to the component connection nodes. Based on the 3D overall model and stress information, determine the internal forces on the 3D node models. Based on the 3D node models, determine the key points of the 3D node models. Based on the 3D overall model and the 3D node models, determine the constraints on the 3D node models. Convert the internal forces on the 3D node models into external forces and uniformly distribute them to the key points. Based on the constraints on the 3D node models, perform strength and stiffness analysis calculations on the 3D node models to determine whether the 3D node models conform to the target design specifications. If the 3D node models do not conform to the target design specifications, adjust the component cross-sectional dimensions or component material properties of the target structure, or adjust the weldless and studless metal tenon and mortise structures corresponding to the 3D node models until the 3D node models conform to the target design specifications. If the 3D node models conform to the target design specifications, determine that the weldless and studless metal tenon and mortise structures corresponding to the 3D node models are the target weldless and studless metal tenon and mortise structures.

[0007] Optionally, obtain a three-dimensional overall model of the target structure that conforms to design specifications, including: A three-dimensional overall model of the target structure is constructed, with the component units of the three-dimensional overall model divided according to the horizontal and vertical connection nodes of the actual components. Strength and stiffness analysis calculations are performed on the three-dimensional overall model to determine whether it conforms to the target design specifications. If the three-dimensional overall model does not conform to the design specifications, each component unit of the three-dimensional overall model is divided into multiple sub-component units, and the strength and stiffness analysis calculations are performed again until the three-dimensional overall model conforms to the target design specifications. If the number of sub-component units corresponding to each component unit of the three-dimensional overall model reaches the preset number, and the three-dimensional overall model still does not conform to the target design specifications, the component cross-sectional dimensions or component material properties of the three-dimensional overall model are adjusted, and the strength and stiffness analysis calculations are performed again until the three-dimensional overall model conforms to the target design specifications.

[0008] Optionally, after determining the internal forces acting on the three-dimensional node models based on the overall three-dimensional model and force information, the method for determining the weld-free and bolt-free metal tenon and mortise structure also includes: Based on the stress distribution type of the component connection nodes, the element meshing method of the three-dimensional node model is determined. The element meshing method includes solid elements and shell elements. When the element meshing method is solid elements, the bending moment and torque on the three-dimensional node model are converted into axial force and shear force.

[0009] Optionally, based on the component connection nodes of the overall 3D model and multiple preset weld-free and stud-free metal tenon and mortise structures, the corresponding 3D node model is determined, including: Based on the geometric form of the component connection nodes, the target preset metal tenon and mortise structure is determined from multiple preset metal tenon and mortise structures without welding or bolts; a three-dimensional single-line model is generated based on the target preset metal tenon and mortise structure without welding or bolts and the component connection nodes; and a three-dimensional node model is generated based on the three-dimensional single-line model.

[0010] Optionally, based on the overall 3D model and the 3D node model, the constraints on the 3D node model are determined, including: Based on the 3D node model, determine the constraint end faces of each component in the 3D node model; and determine the constraints on the constraint end faces as the constraints on the 3D node model.

[0011] Optionally, the internal forces acting on the three-dimensional node model include vertical axial force, transverse axial force, torque, vertical shear force, horizontal shear force, vertical bending moment, and horizontal bending moment.

[0012] Secondly, this application provides a device for determining a weld-free and bolt-free metal tenon and mortise structure, comprising: The acquisition module is used to acquire a three-dimensional overall model of the target structure that conforms to the target design specifications. The three-dimensional overall model contains force information. The model building module is used to determine the 3D node model corresponding to the component connection node based on the component connection node of the 3D overall model and multiple preset weld-free and stud-free metal tenon and mortise structures. The verification module is used to determine the internal forces on the 3D node models based on the overall 3D model and force information; determine the key points of the 3D node models based on the 3D node models; determine the constraints on the 3D node models based on the overall 3D model and the 3D node models; convert the internal forces on the 3D node models into external forces and uniformly distribute them to the key points; perform strength and stiffness analysis calculations on the 3D node models based on the constraints to determine whether the 3D node models meet the target design specifications; if the 3D node models do not meet the target design specifications, adjust the component cross-sectional dimensions or component material properties of the target structure, or adjust the corresponding weldless and studless metal tenon and mortise structure of the 3D node models until the 3D node models meet the target design specifications; if the 3D node models meet the target design specifications, determine that the corresponding weldless and studless metal tenon and mortise structure of the 3D node models is the target weldless and studless metal tenon and mortise structure.

[0013] Thirdly, this application provides a computer device, including: a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the computer program to implement the steps of the method for determining a weldless and studless metal tenon structure as described above.

[0014] Fourthly, this application provides a computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, implements the steps of the method for determining a weldless and studless metal tenon structure as described above.

[0015] Fifthly, this application provides a computer program product, including a computer program that, when executed by a processor, implements the steps of the method for determining a weld-free and bolt-free metal tenon structure as described above.

[0016] According to the specific embodiments provided in this application, the following technical effects are disclosed: This application embodiment obtains a three-dimensional overall model of the target structure that conforms to the target design specifications. Based on the component connection nodes of the three-dimensional overall model and multiple preset weldless and studless metal tenon and mortise structures, a three-dimensional node model corresponding to the component connection nodes of the weldless and studless metal tenon and mortise structure can be constructed. Based on the three-dimensional overall model and force information, the internal forces on the three-dimensional node model are determined. Based on the three-dimensional node model, the key points for force calculation of the weldless and studless metal tenon and mortise structure used to indicate the three-dimensional node model are determined. Based on the three-dimensional overall model and the three-dimensional node model, the constraints on the three-dimensional node model are determined. The internal forces on the three-dimensional node model are converted into external forces and uniformly applied to the key points.

Detailed Implementation

[0019] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0020] To make the above-mentioned objectives, features and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] The method for determining weld-free and bolt-free metal tenon and mortise structures provided in this application embodiment can be applied to, for example... Figure 1 In the application environment shown, terminal 102 communicates with server 104 via a network. A data storage system can store the data that server 104 needs to process. The data storage system can be set up independently, integrated into server 104, or placed in the cloud or on another server. Terminal 102 can send the acquired 3D overall model to server 104. After receiving the 3D overall model, server 104 determines the 3D node model based on the component connection nodes and multiple preset weldless and studless metal tenon and mortise structures of the 3D overall model. Subsequently, it performs strength and stiffness calculations on the 3D node model. After meeting the target design specifications, it designates the weldless and studless metal tenon and mortise structure corresponding to the 3D node model as the target weldless and studless metal tenon and mortise structure. Server 104 can then feed back the obtained target weldless and studless metal tenon and mortise structure to terminal 102. In addition, in some embodiments, the method for determining the weld-free and stud-free metal tenon and mortise structure can also be implemented by the server 104 or the terminal 102 alone. For example, the terminal 102 can directly perform node design and calculation on the acquired three-dimensional overall model, or the server 104 can obtain the three-dimensional overall model from the data storage system and perform node design and calculation on the three-dimensional overall model.

[0022] The terminal 102 can be, but is not limited to, various desktop computers, laptops, smartphones, tablets, IoT devices, and portable wearable devices. IoT devices can include smart speakers, smart TVs, smart air conditioners, and smart in-vehicle devices. Portable wearable devices can include smartwatches, smart bracelets, and head-mounted devices. The server 104 can be implemented using a standalone server or a server cluster composed of multiple servers, or it can be a cloud server.

[0023] In one exemplary embodiment, such as Figure 2 As shown, a method for determining a weld-free and bolt-free metal tenon and mortise structure is provided. This method is executed by a computer device, specifically by a terminal or server alone, or by both a terminal and a server. In this embodiment, the method is applied to... Figure 1 Taking server 104 as an example, the following steps are taken: S201 to S207.

[0024] S201. Obtain a three-dimensional overall model of the target structure that conforms to the target design specifications.

[0025] The three-dimensional overall model contains force information.

[0026] For example, the target structure can be a building structure, sheet metal equipment structure, or other structure with metal as the main structural element, and there are no restrictions on this.

[0027] For example, the target design specifications may include national standards, industry standards, design objectives, etc., and there are no restrictions on this.

[0028] For example, the force information may include the magnitude, type, and other force conditions of each component in the three-dimensional overall model.

[0029] Some possible implementations include obtaining a three-dimensional overall model of the target structure that conforms to design specifications, including: Construct a three-dimensional overall model of the target structure. The component units of the three-dimensional overall model are divided by the horizontal and vertical connection nodes of the actual components. Perform strength and stiffness analysis calculations on the three-dimensional overall model to determine whether the three-dimensional overall model meets the target design specifications.

[0030] When the overall 3D model does not meet the design specifications, the individual component units of the overall 3D model are divided into multiple sub-component units, and the strength and stiffness analysis calculations are performed again until the overall 3D model meets the target design specifications.

[0031] If the number of sub-components corresponding to each component unit of the 3D overall model reaches the preset number, and the 3D overall model still does not meet the target design specifications, adjust the component cross-sectional dimensions or component material properties of the 3D overall model, and re-perform strength and stiffness analysis calculations until the 3D overall model meets the target design specifications.

[0032] For example, a three-dimensional linear model of the target structure can be constructed using CAD software, and then the three-dimensional linear model can be solidified using SAP2000 software to obtain a three-dimensional overall model.

[0033] It is understandable that obtaining a three-dimensional overall model from a three-dimensional linear model through solidification is a conventional technique in this field, and will not be elaborated upon here.

[0034] For example, refer to Figure 3 Taking the example that points 1 to 2 and 2 to 3 are all steel columns, and points 4 to 2 and 2 to 5 are all steel beams in the actual components, points 1 to 2 can be regarded as a component unit, points 2 to 3 as a component unit, points 4 to 2 as a component unit, and points 2 to 5 as a component unit.

[0035] For example, the strength and stiffness analysis of the three-dimensional overall model can be performed using SAP2000 software, which is a conventional technique in this field and will not be elaborated further here.

[0036] For example, when the overall 3D model does not meet the design specifications after analysis and calculation, refer to... Figure 3 Continuing with the example above, the component unit corresponding to point 1 to point 2 can be divided into two sub-component units: point 1 to point 6 and point 6 to point 2. The component unit corresponding to point 2 to point 3 can be divided into two sub-component units: point 2 to point 7 and point 7 to point 3. The division of the remaining component units is similar and will not be repeated here.

[0037] It should be noted that sub-component elements can be obtained by equally dividing the original component elements.

[0038] It should be noted that dividing the sub-components into units can improve the calculation accuracy when performing strength and stiffness analysis on the overall three-dimensional model, thus avoiding misjudgments in structural design due to insufficient calculation accuracy.

[0039] For example, the preset quantity is set manually to balance computational efficiency and computational accuracy, and there is no restriction on the value of the preset quantity.

[0040] In this way, by dividing the component units into secondary components, a three-dimensional overall model of the target structure that conforms to the design specifications can be obtained quickly and accurately.

[0041] S202. Based on the component connection nodes of the three-dimensional overall model and multiple preset non-welding and non-bolt metal tenon and mortise structures, determine the three-dimensional node model corresponding to the component connection nodes.

[0042] Specifically, S202 may include the following steps: Based on the geometric form of the component connection nodes, the target preset metal tenon and mortise structure is determined from multiple preset metal tenon and mortise structures without welding or bolts; a three-dimensional single-line model is generated based on the target preset metal tenon and mortise structure without welding or bolts and the component connection nodes; and a three-dimensional node model is generated based on the three-dimensional single-line model.

[0043] For example, the geometric form of the component connection node may include a cross shape, a T shape (which can be further divided into upper T shape, lower T shape, left T shape, right T shape), etc., and there is no limitation on its form; multiple preset weldless and nail-free metal tenon and mortise structures may include weldless and nail-free metal tenon and mortise node structures for each type of component connection node, and multiple preset weldless and nail-free metal tenon and mortise structures may correspond to different component connection node geometric forms, and there is no limitation on the specific structural style of the preset weldless and nail-free metal tenon and mortise structures.

[0044] For example, the geometric information of the component connection nodes can be included in the overall three-dimensional model. After obtaining the overall three-dimensional model, the preset weldless and studless metal tenon and mortise structure corresponding to the geometric form of the component connection nodes can be determined as the target preset weldless and studless metal tenon and mortise structure.

[0045] For example, based on the physical dimensions of the actual components in the component connection nodes and combined with the target preset weldless and boltless metal tenon and mortise structure, a three-dimensional single-line model corresponding to the component connection nodes can be generated using CAD software. For instance, the three-dimensional single-line models corresponding to cross-shaped, upper T-shaped, lower T-shaped, left T-shaped, and right T-shaped nodes can be generated as follows: Figure 4 The images are shown from left to right.

[0046] For example, after obtaining the three-dimensional single-line model, the three-dimensional single-line model can be imported into ANSYS software for solidification processing, and the three-dimensional single-line model can be stretched into a three-dimensional node model.

[0047] It is understandable that the physical dimensions of the three-dimensional node model obtained by stretching are not larger than the physical dimensions of the actual component, and the structural form of the target preset non-welded and non-studded metal tenon and mortise structure is completely included.

[0048] Continuing with the previous example, the 3D node models corresponding to the cross shape, upper T-shape, lower T-shape, left T-shape, and right T-shape can be as follows: Figure 5 The images are shown from left to right.

[0049] S203. Based on the overall three-dimensional model and force information, determine the internal forces acting on the three-dimensional node models.

[0050] For example, the SAP2000 software can be used to calculate the resultant force of each internal force (vertical axial force, transverse axial force, torque, vertical shear force, horizontal shear force, vertical bending moment, horizontal bending moment, etc.) on the three-dimensional node model based on the overall three-dimensional model and force information, so as to obtain the various internal forces (total vertical axial force, total transverse axial force, total torque, total vertical shear force, total horizontal shear force, total vertical bending moment, total horizontal bending moment, etc.) on the three-dimensional node model.

[0051] It should be noted that, given the known overall three-dimensional model and force information, determining the internal forces acting on the three-dimensional node model using SAP2000 software is a conventional technique in this field and will not be elaborated upon here.

[0052] S204. Based on the 3D node model, determine the key points of the 3D node model.

[0053] The key point is to perform stress calculations on the weld-free and bolt-free metal tenon and mortise structure of the three-dimensional node model in finite element calculation software (such as ANSYS software).

[0054] It should be noted that the determination of key points is a conventional technical method in this field, and will not be elaborated here.

[0055] S205. Based on the overall 3D model and the 3D node model, determine the constraints on the 3D node model.

[0056] Specifically, S205 may include the following steps: Based on the 3D node model, determine the constraint end faces of each component in the 3D node model; and determine the constraints on the constraint end faces as the constraints on the 3D node model.

[0057] For example, each end face in a 3D node model can be defined as a constraint end face.

[0058] For example, the constraint on the constraint end face can be determined based on the position of the constraint end face in the three-dimensional overall model component and the constraint status of the three-dimensional overall model component.

[0059] For example, when the left end face of a cross-shaped 3D node model is located in a rigid beam in a 3D global model, and the left end of the rigid beam is a fixed constraint in the 3D global model, then the constraint on the left end face of the 3D node model is a fixed constraint from the rigid beam itself. When the left end face of a cross-shaped 3D node model is exactly the left end face of a rigid beam in the 3D global model, and the left end of the rigid beam in the 3D global model is a hinged constraint, then the constraint on the left end face of the 3D node model is a hinged constraint.

[0060] It is understandable that the constraint end faces in the 3D node model may not exist in the actual structure.

[0061] S206. Convert the internal forces on the 3D node model into external forces and uniformly apply them to the key points. Based on the constraints on the 3D node model, perform strength and stiffness analysis calculations on the 3D node model to determine whether the 3D node model meets the target design specifications.

[0062] For example, the various internal forces (total vertical axial force, total horizontal axial force, total torque, total vertical shear force, total horizontal shear force, total horizontal bending moment, total vertical bending moment, etc.) of the three-dimensional node model can be converted into external forces and then applied evenly to all key points. That is, the various external forces borne by each key point are the ratio of the external forces corresponding to the various internal forces of the three-dimensional node model to the number of key points.

[0063] It should be noted that the specific implementation method of using ANSYS software to perform strength and stiffness analysis calculations on the three-dimensional node model based on the constraints imposed on the three-dimensional node model is a conventional technical method in this field and will not be elaborated here.

[0064] S207. When the three-dimensional node model does not conform to the target design specifications, adjust the component cross-sectional dimensions or component material properties of the target structure, or adjust the weldless and studless metal tenon and mortise structure corresponding to the three-dimensional node model until the three-dimensional node model conforms to the target design specifications; when the three-dimensional node model conforms to the target design specifications, determine the weldless and studless metal tenon and mortise structure corresponding to the three-dimensional node model as the target weldless and studless metal tenon and mortise structure.

[0065] It is understandable that after adjusting the component cross-sectional dimensions or component material properties of the target structure, it is necessary to first obtain a new three-dimensional overall model that conforms to the target design specifications, and then re-execute S202 to S206.

[0066] For example, when adjusting the weldless and nail-free metal tenon and mortise structure corresponding to the three-dimensional node model, the position and size of the tenon and mortise in the weldless and nail-free metal tenon and mortise structure can be adjusted without restriction. After adjustment, S203 to S206 are repeated. The main purpose is to calculate and verify whether the adjusted weldless and nail-free metal tenon and mortise structure meets the specifications. If it meets the specifications and meets the design requirements, it is acceptable.

[0067] It can be understood that once the target weld-free and stud-free metal tenon and mortise structure corresponding to each component connection node in the target structure is obtained, the node design for the target structure is completed.

[0068] This application embodiment obtains a three-dimensional overall model of the target structure that conforms to the target design specifications. Based on the component connection nodes of the three-dimensional overall model and multiple preset weldless and studless metal tenon and mortise structures, a three-dimensional node model corresponding to the component connection nodes of the weldless and studless metal tenon and mortise structure can be constructed. Based on the three-dimensional overall model and force information, the internal forces on the three-dimensional node model are determined. Based on the three-dimensional node model, the key points for force calculation of the weldless and studless metal tenon and mortise structure used to indicate the three-dimensional node model are determined. Based on the three-dimensional overall model and the three-dimensional node model, the constraints on the three-dimensional node model are determined. The internal forces on the three-dimensional node model are converted into external forces and uniformly applied to the key points. Based on the constraints on the three-dimensional node model, the strength and stiffness analysis calculation of the three-dimensional node model is performed to determine the target weldless and studless metal tenon and mortise structure corresponding to the three-dimensional node model. This enables the design and verification of weldless and studless metal tenon and mortise structures for the node construction of metal structures, allowing the weldless and studless metal tenon and mortise structures to be applied to various metal structures.

[0069] In some possible embodiments, after determining the internal forces acting on the three-dimensional node models based on the overall three-dimensional model and force information, the method for determining the weld-free and bolt-free metal tenon and mortise structure further includes: Based on the stress distribution type of the component connection nodes, the element meshing method of the three-dimensional node model is determined. The element meshing method includes solid elements and shell elements. When the element mesh is set to solid elements, the bending moment and torque experienced by the 3D node model are converted into axial force and shear force.

[0070] In this way, when the element meshing method is solid element, the bending moment and torque of the 3D node model that cannot be loaded at the key points can be converted into axial force and shear force, thereby improving the calculation accuracy of the strength and stiffness of the 3D node model.

[0071] This application also provides an application scenario in which the above-mentioned method for determining weldless and bolt-free metal tenon and mortise structures is applied. Specifically, the method for determining weldless and bolt-free metal tenon and mortise structures provided in this embodiment can be applied in the design of metal structure buildings. When designing metal structure buildings, the overall structural design is performed first. After the overall structural design meets the requirements, node design is required, which involves designing and verifying the specific connection methods of the nodes in the overall structure. The method for determining weldless and bolt-free metal tenon and mortise structures provided in this embodiment belongs to this node design stage.

[0072] Based on the same inventive concept, this application also provides a device for determining a weldless and nail-free metal tenon and mortise structure, used to implement the aforementioned method for determining weldless and nail-free metal tenon and mortise structures. The solution provided by this device is similar to the solution described in the above method. Therefore, the specific limitations of one or more embodiments of the weldless and nail-free metal tenon and mortise structure determining device provided below can be found in the limitations of the weldless and nail-free metal tenon and mortise structure determining method described above, and will not be repeated here.
