It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein.

[0014] Figure 1 This is a flowchart illustrating a method for updating a three-dimensional digital model of a composite component according to an embodiment of the present invention. This embodiment is applicable to updating the three-dimensional digital model of composite components during the civil engineering process of substation projects. The method can be executed by a device for updating the three-dimensional digital model of composite components. This device can be implemented in hardware and / or software and can be configured in an electronic device that implements the method for updating the three-dimensional digital model of composite components. Figure 1 As shown, the method for updating the three-dimensional digital model of this composite component includes: S101. Based on the first data and the target load, a structural calculation is performed on the target composite component to obtain a first calculation result, and a first detection result is determined based on the first calculation result. The target composite component is a composite component formed by connecting multiple sub-components during the civil engineering process of a substation project. The first data includes the values ​​corresponding to various structural parameters of each sub-component. The target load is the load applied to the target composite component. The first detection result is used to indicate whether the target composite component generated based on the first data meets the target load.

[0015] In this context, substation engineering refers to construction projects aimed at achieving voltage level conversion, power distribution, and dispatch control. Substation engineering includes civil engineering and electrical installation processes. The civil engineering process can refer to the entire construction process of the foundation, buildings, and structures within a substation. Sub-components can include at least: columns, beams, and braces. The various structural parameters of a sub-component can include at least its geometric parameters, cross-sectional parameters, and material parameters. The geometric parameters of a sub-component can be used to characterize its overall spatial shape and axial position. The cross-sectional parameters of a sub-component can be used to characterize its cross-sectional shape. The target composite component can include at least a support frame. The target load can include at least: dead load, wind load, icing load, and maintenance load.

[0016] Specifically, by performing structural calculations on the target composite member based on the first data and the target load, the structural calculation results of the target composite member generated based on the first data under the target load can be determined, thus obtaining the first calculation result. Furthermore, if the first calculation result meets the set threshold corresponding to the target composite member, it indicates that the target composite member generated based on the first data meets the target load; if the first calculation result does not meet the set threshold corresponding to the target composite member, it indicates that the target composite member generated based on the first data does not meet the target load.

[0017] For example, for a lattice column in the target composite member, the first calculation result may include axial compressive stability, limb stability, and lacing stress; for a lattice beam in the target composite member, the first calculation result may include bending stress, deflection, and overall stability.

[0018] As an optional embodiment of the present invention, the first calculation result includes the structural calculation result of each sub-component, and the structural calculation result of the sub-component includes at least one of the axial force, shear force, bending moment, torque, stress ratio and bearing capacity of the sub-component.

[0019] Specifically, structural calculations for the target composite component can include structural calculations for each sub-component in the target composite component, thereby obtaining the structural calculation results for each sub-component, and determining whether the sub-component meets the target load based on the structural calculation results of the sub-component.

[0020] S102. In response to the first detection result indicating that the target composite component generated based on the first data does not meet the target load, the first data is adjusted based on the first calculation result to obtain second data, and the second data is used to control the target composite component generated based on the second data to meet the target load.

[0021] Specifically, when the target composite component generated based on the first data does not meet the target load, some values ​​in the first data can be adjusted based on the first calculation result to obtain new first data. Furthermore, the steps of performing structural calculations on the target composite component based on the first data and the target load to obtain the first calculation result, and determining the first detection result based on the first calculation result, can be repeated until the first detection result indicates that the target composite component generated based on the first data meets the target load. Then, the final first data is used as the second data.

[0022] For example, when adjusting the first data, the values ​​corresponding to the cross-sectional parameters in the first data can be adjusted first, and then the values ​​corresponding to the geometric parameters can be adjusted. When the column cross-section is updated, the centerline position of the column leg, the length of the tie rod, the hole position of the node plate and the coordinates of the connector are recalculated; when the beam parameters are updated, the beam end plate size, bolt arrangement, weld arrangement, beam-column connection gap and the lap length of adjacent components are adjusted synchronously.

[0023] S103. The three-dimensional digital model of the target composite component is updated based on the second data and the first information. The first information is used to indicate the connection relationship between the sub-components in the target composite component. The three-dimensional digital model of the target composite component is constructed based on the first data through the parameterized template of each sub-component. The parameterized template of the sub-component is used to generate the three-dimensional digital model of the sub-component based on the various structural parameters of the sub-component.

[0024] The connection relationships between sub-components can be used to characterize the geometric positional constraints, assembly constraints, mechanical transfer methods, and structural connection methods between them. The 3D digital model generated based on the parametric templates of the sub-components is numerically correlated with the various structural parameters of the sub-components.

[0025] Specifically, for each sub-component in the target composite structure, the 3D digital model of the sub-component can be updated using a parametric template based on the numerical values ​​of various structural parameters corresponding to the sub-component in the second data. Furthermore, based on the first information and the updated 3D digital model corresponding to each sub-component, the updated 3D digital model corresponding to the target composite structure is determined, reducing misalignment between sub-components. Structural calculations and parametric design lower the cost of updating the 3D digital model, improve update efficiency, and adapt to the design requirements of substation engineering.

[0026] For example, the parametric template of the sub-component includes a parametric reconstruction function, which is used to update the three-dimensional digital model of the sub-component based on the adjusted values ​​corresponding to various structural parameters of the sub-component.

[0027] As an optional implementation of this invention, updating the three-dimensional digital model of the target composite component based on the second data and the first information includes: determining the target sub-component and the third data of the target sub-component based on the second data, wherein the target sub-component is a sub-component in the target composite component whose structural parameters have been adjusted, and the third data of the target sub-component includes the values ​​corresponding to the various structural parameters of the target sub-component in the second data; and updating the three-dimensional digital model of the target composite component based on the parameterized template of the target sub-component, using the third data of the target sub-component as a constraint of the first information.

[0028] Specifically, the second data can be obtained by adjusting some values ​​in the first data, thereby identifying at least one target sub-component in the target assembly. Furthermore, for each of the at least one target sub-component, a corresponding updated 3D digital model can be generated based on the third data of the target sub-component and its parameterized template. Finally, constrained by the first information, and based on the updated 3D digital model corresponding to each target sub-component, the 3D digital model of the target assembly can be updated to further improve the efficiency of model updating.

[0029] For example, the method for updating the 3D digital model of a composite component can be executed by a 3D digital model updating system for composite components. The 3D digital model updating system for composite components includes: a 3D design core layer, a structural calculation engine layer, and a data interaction layer. Specifically, the 3D design core layer is used to parametrically construct the 3D numerical model of the target composite component based on the numerical values ​​corresponding to various structural parameters of each sub-component in the target composite component; the structural calculation engine layer is used to perform structural calculations on the target composite component based on the loads applied to it and the numerical values ​​corresponding to various structural parameters of each sub-component in the target composite component, thereby adjusting the numerical values ​​corresponding to the various structural parameters of the sub-components; the data interaction layer is used to synchronize the numerical values ​​corresponding to the various structural parameters of each sub-component in the target composite component between the 3D design core layer and the structural calculation engine layer.

[0030] The technical solution of this invention involves performing structural calculations on a target composite component based on first data and a target load to obtain a first calculation result, and then determining a first detection result based on the first calculation result. The target composite component is a composite component formed by connecting multiple sub-components during the civil engineering process of a substation project. The first data includes the numerical values ​​corresponding to various structural parameters of each sub-component. In response to the first detection result indicating that the target composite component generated based on the first data does not meet the target load, the first data is adjusted based on the first calculation result to obtain second data. The second data is used to control the target composite component generated based on the second data to meet the target load. This achieves structural calculation of the target composite component based on the load applied to it and the numerical values ​​corresponding to various structural parameters of each sub-component in the target composite component, thereby determining the numerical values ​​corresponding to various structural parameters of the sub-components based on the calculation results. The values ​​are adjusted until the target composite component generated based on the adjusted values ​​meets the load applied to the target composite component; the three-dimensional digital model of the target composite component is updated based on the second data and the first information. The first information is used to indicate the connection relationship between the sub-components in the target composite component. The three-dimensional digital model of the target composite component is constructed based on the first data through the parameterized template of each sub-component. It realizes the values ​​corresponding to the various structural parameters of the sub-components in the second data. The three-dimensional digital model of the sub-components is updated through the parameterized template of the sub-components. Thus, based on the first information and the updated three-dimensional digital model corresponding to each sub-component, the updated three-dimensional digital model corresponding to the target composite component is determined, so as to reduce the misalignment between the sub-components. The cost of updating the three-dimensional digital model is reduced by structural calculation and parameterized design, and the update efficiency is improved.

[0031] Figure 2 This is a flowchart of another method for updating a three-dimensional digital model of a composite component provided by an embodiment of the present invention. The technical solution of this embodiment further optimizes the process of obtaining a first calculation result by performing structural calculations on the target composite component based on first data and target load, based on the technical solutions of the above embodiments. Solutions not described in detail in this embodiment are found in the above embodiments. This embodiment can be combined with various optional solutions in one or more of the above embodiments. Figure 2 As shown, the method for updating the three-dimensional digital model of this composite component includes: S201. Determine the load combination matrix corresponding to the target load, and determine the structural analysis model corresponding to the target combined component.

[0032] The load combination matrix can be a two-dimensional matrix composed of load combination cases and load types. Each row in the load combination matrix represents a load combination case, and each column represents a type of load. The element values ​​in the load combination matrix represent the coefficient values ​​of the loads in the load combination cases, which are determined based on partial factors and combination factors. The structural analysis model can be performed using spatial finite element analysis for mechanical calculations.

[0033] Specifically, based on the various loads in the target load and the corresponding working conditions of the target composite component, a load combination matrix corresponding to the target load can be generated. Based on each sub-component and the connection relationships between them, the structural analysis model corresponding to the target composite component can be determined.

[0034] As an optional implementation of the present invention, determining the structural analysis model corresponding to the target composite component includes: for each sub-component in the target composite component, determining the structural analysis model corresponding to the sub-component based on the material type and component type of the sub-component; and determining the structural analysis model corresponding to the target composite component based on the first information and the structural analysis model corresponding to each sub-component.

[0035] Specifically, based on the material type and component type of the sub-components, the structural analysis model corresponding to the sub-components can be selected from a preset model set. Furthermore, based on the structural analysis model corresponding to each sub-component, the structural analysis model corresponding to the target composite component can be determined based on the first information, thereby improving the accuracy of structural calculations for the target composite component.

[0036] S202. Based on the first data and the load combination matrix, determine the first calculation result through the structural analysis model corresponding to the target combined component, and determine the first detection result based on the first calculation result.

[0037] Specifically, by inputting the first data and the load combination matrix corresponding to the target load into the structural analysis model corresponding to the target combined component, the first calculation result can be output through the structural analysis model corresponding to the target combined component, so as to improve the accuracy of the first calculation result.

[0038] For example, the structural analysis model corresponding to the target composite component can establish an overall stiffness equation KΔ=F, where K is the overall structural stiffness matrix, Δ is the nodal displacement vector, and F is the equivalent load vector; by solving the nodal displacement vector, the structural calculation results of each sub-component can be further calculated.

[0039] S203. In response to the first detection result indicating that the target composite component generated based on the first data does not meet the target load, the first data is adjusted based on the first calculation result to obtain second data, and the second data is used to control the target composite component generated based on the second data to meet the target load.

[0040] S204. Update the three-dimensional digital model of the target composite component based on the second data and the first information. The first information is used to indicate the connection relationship between the sub-components in the target composite component. The three-dimensional digital model of the target composite component is constructed based on the first data through the parameterized template of each sub-component. The parameterized template of the sub-component is used to generate the three-dimensional digital model of the sub-component based on various structural parameters of the sub-component.

[0041] As an optional embodiment of the present invention, after updating the three-dimensional digital model of the target composite component based on the second data and the first information, the method further includes: determining multiple connection nodes in the target composite component, wherein the connection nodes are used to connect at least two sub-components; for each of the multiple connection nodes, determining the fourth data of the connection node, wherein the fourth data of the connection node includes the numerical values ​​corresponding to various structural parameters of the connection node; and constructing a three-dimensional digital model of the connection node based on the fourth data corresponding to the connection node.

[0042] Specifically, the target composite component can be formed by connecting multiple sub-components through connection nodes. Furthermore, for each connection node in the target composite component, a 3D digital model of the connection node can be constructed based on the fourth data of the connection node using a parameterized template, thus supplementing the 3D digital model of the target composite component. The parameterized template of the connection node is used to generate a 3D digital model of the connection node based on various structural parameters of the connection node.

[0043] As an optional implementation of this invention, determining the fourth data of the connection node includes: determining the connection type corresponding to the connection node, and determining the fourth data of the connection node based on the connection type corresponding to the connection node and the fifth data. The fifth data includes the sixth data of each sub-component connected by the connection node, and the sixth data of the sub-component includes the values ​​corresponding to various structural parameters of the sub-component in the second data.

[0044] Specifically, based on at least two sub-components connected by a connection node in the target composite component, the fifth data can be determined from the second data. Based on the connection type corresponding to the connection node, various structural parameters of the connection node can be determined. Therefore, by setting the values ​​corresponding to these various structural parameters of the connection node based on the fifth data, the fourth data of the connection node can be obtained. The connection types corresponding to the connection node can include at least: welded connection, bolted connection, pin connection, and flange connection.

[0045] For example, based on the fifth data, the internal force transmitted from the sub-component to the connection node can be determined, and then based on the internal force, the values ​​corresponding to various structural parameters of the connection node can be calculated.

[0046] For example, based on at least two sub-components connected by a connection node, a node coordinate system is established with the intersection of the sub-components as the local coordinate origin. The thickness of the node plate, the size of the end plate, the number of stiffeners, the bolt hole diameter, the hole spacing, the edge distance, and the weld arrangement are determined according to the calculated internal force design values ​​and construction rules. Then, by calling the corresponding parametric template, the node plate, end plate, stiffeners, bolt holes, weld entities, and chamfer structures are generated sequentially. Holes are formed through Boolean subtraction, and the connection node is bound to the sub-component through constraint relationships.

[0047] For welds at connection nodes, based on the calculated internal forces of the connection nodes, including axial force, shear force, bending moment, and their corresponding load combination numbers, the start point, end point, weld leg height, effective length, and weld direction of each weld are determined. Specifically, the weld is discretized into several weld micro-segments according to a preset step size or endpoint turning position. For the i-th weld micro-segment, the effective throat thickness, effective area, and center coordinates of the micro-segment are calculated, forming a set of weld group calculation units. Next, the centroid coordinates are calculated using the effective area of ​​the weld group as the weight, and the moment of inertia and polar moment of inertia of the weld group about the local coordinate axes are calculated. For axial force and shear force transmitted from the connection nodes, direct stress is allocated based on the effective area of ​​the weld micro-segment. For bending moment, additional stress is allocated based on the distance from the weld micro-segment to the centroid and the moment of inertia. Based on the direct shear stress, bending moment additional stress, and torsional shear stress of each weld micro-segment, vector superposition is performed according to the local weld direction to obtain the normal stress, parallel shear stress, and perpendicular shear stress of that weld micro-segment, and equivalent stress is calculated. The equivalent stress of each weld micro-segment is compared with the weld design strength to obtain the utilization coefficient of each weld micro-segment, and the maximum utilization coefficient is used as the weld strength control index. If the weld strength control index is not greater than 1 and the weld leg height, effective length, minimum spacing, structural continuity, and construction accessibility all meet the requirements, the weld strength is deemed to meet the requirements. If the weld strength control index is greater than 1, the iterative optimization process is initiated, adjusting in the following order: first, increasing the weld leg height of the control micro-segment; second, extending the effective weld length; and third, adding stiffening ribs or adjusting the thickness of the node plate, until the weld strength control index is not greater than 1 or the preset number of iterations is reached.

[0048] The technical solution of this invention determines the load combination matrix corresponding to the target load and the structural analysis model corresponding to the target composite component; based on the first data and the load combination matrix, a first calculation result is determined through the structural analysis model corresponding to the target composite component, and a first detection result is determined based on the first calculation result. This achieves the input of the first data and the load combination matrix corresponding to the target load into the structural analysis model corresponding to the target composite component, and the output of the first calculation result through the structural analysis model corresponding to the target composite component, thereby improving the accuracy of the first calculation result; in response to the first detection result indicating that the target composite component generated based on the first data does not meet the target load, the first calculation result is used to... The first data is adjusted to obtain the second data, which is used to control the target composite component generated based on the second data to meet the target load. The three-dimensional digital model of the target composite component is updated based on the second data and the first information. The first information is used to indicate the connection relationship between the sub-components in the target composite component. The three-dimensional digital model of the target composite component is constructed based on the first data through the parameterized template of each sub-component. This realizes the updated three-dimensional digital model based on the first information and each corresponding sub-component, and determines the updated three-dimensional digital model corresponding to the target composite component. By using structural calculation and parameterized design, the cost of updating the three-dimensional digital model is reduced and the updating efficiency is improved.

The target sub-component is a sub-component in the target composite component whose structural parameters have been adjusted. The third data of the target sub-component includes the values ​​corresponding to various structural parameters of the target sub-component in the second data. The second update unit is used to update the three-dimensional digital model of the target composite component based on the third data of the target sub-component, constrained by the first information, using the parameterized template of the target sub-component.

[0053] Based on any of the above-mentioned optional technical solutions, the three-dimensional digital model updating device for the combined component may optionally further include: a seventh determining module, an eighth determining module, and a first constructing module. The seventh determining module is used to determine multiple connection nodes in the target combined component, where each connection node connects at least two sub-components; the eighth determining module is used to determine fourth data for each of the multiple connection nodes, where the fourth data includes numerical values ​​corresponding to various structural parameters of the connection node; and the first constructing module is used to construct a three-dimensional digital model of the connection node based on the fourth data corresponding to the connection node.

[0054] Based on any of the above optional technical solutions, optionally, the eighth determining module is specifically used to determine the connection type corresponding to the connection node, and to determine the fourth data of the connection node based on the connection type corresponding to the connection node and the fifth data. The fifth data includes the sixth data of each sub-component connected by the connection node, and the sixth data of the sub-component includes the values ​​corresponding to the various structural parameters of the sub-component in the second data.

[0055] Based on any of the above optional technical solutions, optionally, the first calculation result includes the structural calculation result of each sub-component, and the structural calculation result of the sub-component includes at least one of the axial force, shear force, bending moment, torque, stress ratio and bearing capacity of the sub-component.

[0056] The technical solution of this invention involves a first determining module 301 performing structural calculations on a target composite component based on first data and a target load to obtain a first calculation result, and then determining a first detection result based on the first calculation result. The target composite component is a composite component formed by connecting multiple sub-components during the civil engineering process of a substation project. The first data includes the numerical values ​​corresponding to various structural parameters of each sub-component. In response to the first detection result indicating that the target composite component generated based on the first data does not meet the target load, a first adjusting module 302 adjusts the first data based on the first calculation result to obtain second data. The second data is used to control the target composite component generated based on the second data to meet the target load. This achieves structural calculations on the target composite component based on the load applied to it and the numerical values ​​corresponding to various structural parameters of each sub-component in the target composite component, thereby adjusting the various structural parameters of the sub-components based on the calculation results. The corresponding values ​​are adjusted until the target composite component generated based on the adjusted values ​​meets the load applied to the target composite component. The three-dimensional digital model of the target composite component is updated by the first update module 303 based on the second data and the first information. The first information is used to indicate the connection relationship between the sub-components in the target composite component. The three-dimensional digital model of the target composite component is constructed based on the first data through the parameterized template of each sub-component. It realizes the numerical values ​​corresponding to the various structural parameters of the sub-components in the second data. The three-dimensional digital model of the sub-components is updated through the parameterized template of the sub-components. Thus, based on the first information and the updated three-dimensional digital model corresponding to each sub-component, the updated three-dimensional digital model corresponding to the target composite component is determined. This reduces the occurrence of misalignment between sub-components and reduces the cost of updating the three-dimensional digital model through structural calculation and parameterized design, thereby improving the update efficiency.
