Description

Technical Field

[0001] The present disclosure relates to the technical field of gate hoist structure design, and in particular to a finite element calculation method and system for a gate hoist structure. Background Art

[0002] In existing water conservancy and hydropower projects, gate hoists, as key mechanical devices, are widely used to control the raising and lowering of gates. Their structural design is directly related to the safety and reliability of project operations. Winch-type gate hoists, due to their simple structure and high load-bearing capacity, are commonly used in large and medium-sized hydraulic structures. Their trolleys or frames, as crucial structural units that carry the lifting load, provide support and mechanical transmission for key equipment such as fixed pulley blocks, drum devices, and speed reducers. Therefore, the design and verification of the trolley or frame structure has always been a core component of gate hoist structural analysis.

[0003] In engineering practice, simplified planar structure analysis methods are often used to analyze the stresses on trolley frames or racks. This type of method often uses a single beam as the modeling object, ignoring the spatial coupling relationship between the various beam systems in the overall frame structure. To meet the engineering accuracy requirements, each beam component must be independently verified. Not only is the calculation process cumbersome, but it is also easy to overlook key structural effects such as node linkage and torsional bending coupling. In addition, the load distribution in the simplified analysis is too idealized, making it difficult to accurately simulate the actual action path of the equipment load. In other words, it is impossible to accurately reflect the internal force distribution at the segmented connections and variable-section beams. There is a certain degree of calculation deviation, which is not conducive to the accurate evaluation of structural safety.

[0004] Therefore, there is an urgent need to provide a calculation scheme that can take into account the actual structural layout of the project and improve the accuracy and efficiency of structural analysis, so as to more effectively serve the rapid design and safety assessment of the gate hoist support structure.

[0005] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present disclosure, and therefore may include information that does not constitute prior art known to ordinary technicians in the field.

[0061] The embodiment of the present disclosure provides a finite element calculation method for a gate hoist structure, referring to Figure 2 As shown, the method may include steps S210 to S240:

[0062] Step S210, obtaining structural parameters and boundary parameters of the gate hoist support structure;

[0063] Step S220 , selecting a target floor plan layout type from a plurality of preset standardized floor plan layout types based on the structural parameters;

[0064] Step S230, combining the structural parameters and the target planar layout type to construct a parameterized structural geometric model, and discretizing the parameterized structural geometric model into a finite element model including a load-bearing beam unit;

[0065] Step S240 , applying loads and boundary conditions corresponding to the boundary parameters to the finite element model, and performing structural mechanics solution calculations to obtain structural calculation results under the target plane layout type.

[0066] The finite element calculation method for the gate hoist structure provided by the present disclosure can realize the automation of the entire process from input of structural parameters and boundary parameters to modeling, solving, and output. On the one hand, by introducing a standardized plane layout type, the modular reuse capability of the structural layout under different engineering conditions is improved, and the error of manual layout judgment is avoided; on the other hand, in the process of structural modeling, the target layout type and the structural size parameters work together to realize the synchronous definition of the topological structure and geometric dimensions of the load-bearing beam system, retain the spatial linkage relationship between the beam systems in the frame structure, and overcome the problem of the lack of beam system coupling in simplified modeling; on the other hand, after the parametric structural geometric model is discretized into a finite element model containing the load-bearing beam unit, the load and constraint conditions in the boundary parameters are accurately applied, which can restore the actual transfer path of the load in the structure, improve the ability to capture the mechanical response of key parts, reduce the structural deviation in traditional calculations, and support the automation, high precision and standardized operation of structural analysis.

[0067] Next, the finite element calculation method for the hoist structure in this example embodiment will be described in detail.

[0068] In step S210, the structural parameters and boundary parameters of the gate hoist support structure are obtained.

[0069] A gate hoist, also known as hydraulic gate hoisting equipment, refers to a complete set of mechanical devices used to raise or lower hydraulic gates to control water flow, regulate water levels, or retain water. Types of gate hoists include, but are not limited to, winch-type, hydraulic, screw, and mobile gate hoists.

[0070] The example embodiments of this disclosure use a winch-type gate hoist as an example. The gate hoist support structure refers to the load-bearing frame that supports key components such as the winch, reducer, and fixed pulley assembly, and transmits operating loads to the underlying foundation structure or fixed anchoring locations. This support structure, typically a trolley frame (also known as a platform frame) or a machine frame, is the core mechanical load-bearing unit in a winch-type gate hoist. The gate hoist support structure, composed of multiple beam-based components, performs important installation, connection, and force transmission tasks within the gate hoist. Its structural performance is directly related to the safety and stability of the overall operation of the gate hoist.

[0071] Among them, the structural parameters of the hoist support structure are used to characterize the basic features of the hoist support structure in terms of geometric layout and dimensional configuration. In the exemplary embodiment of the present disclosure, the structural parameters include structural layout type parameters and structural dimension parameters. The structural layout type parameters are used to determine the standardized structural topology category to which the hoist support structure belongs, serving as the basis for the structural template for subsequent parametric modeling; the structural dimension parameters are used to describe the geometric properties of various load-bearing beam systems such as main beams, side beams, transverse beams, and longitudinal beams, including member lengths, cross-sectional dimensions, arrangement layers, and relative position relationships between members, etc., which are the key inputs for generating the parametric structural geometric model.

[0072] The boundary parameters of the hoist support structure are used to define the load application conditions and boundary constraint conditions of the hoist support structure during the force analysis process. The boundary parameters include load parameters and constraint condition parameters. The load parameters are used to represent the type, magnitude of the concentrated load or distributed load, and its application position in the model, which is the basis for constructing the actual working conditions of the structure. The constraint condition parameters are used to define the boundary states of each node or support part in the model, including the direction of the constrained degrees of freedom and their corresponding support types, such as fixed, sliding, or hinged connection methods.

[0073] This step can achieve the comprehensive acquisition of information on the hoist support structure in two dimensions of geometric configuration and force-bearing boundaries, providing a complete and standardized engineering input basis for layout type selection, parametric modeling, and finite element solution.

[0074] In step S220, based on the structural parameters, a target planar layout type is selected from a variety of preset standardized planar layout types.

[0075] In this step, the most suitable layout structure for the current engineering design requirements can be selected and matched from multiple preset structural layout templates through the structural parameters. In the exemplary embodiment of the present disclosure, the standardized planar layout types are typical topological structures summarized and sorted according to the common support structure forms in the hydraulic hoist project, which are used to provide the structural topology basis during the modeling process. Exemplarily, it can include planar layout types such as "day" shape, "you" shape, "field" shape, "er" shape, and "four" shape. Of course, other types of configurations can also be included, and the present disclosure does not limit this. Among them, the planar layout types of "day" shape, "you" shape, and "field" shape are common load-bearing structure layouts for single-hoisting-point lifting mechanisms, and the planar layout types of "er" shape and "four" shape are common load-bearing structure layouts for double-hoisting-point lifting mechanisms.

[0076] It should be noted that each standardized planar layout type is composed of a basic frame structure and transverse beam systems and longitudinal beam systems connected to the basic frame structure. The basic frame structure, as the rigid support unit of the overall structure, determines the basic shape and overall stability of the standardized planar layout type.

[0077] Among them, the basic frame structure is composed of a main beam system and a side beam system. For example, the basic frame structure includes two side beams symmetrically arranged on the left and right and a main beam transversely connected between the two side beams, and this structure forms a basic "H" - shaped frame structure, which is a commonly used force - bearing core unit in the support structure of a hoist - type gate hoist. The side beam system mainly bears vertical load - bearing and stability control, while the main beam system plays the role of connecting side beams, distributing loads, and increasing lateral stiffness.

[0078] Based on the "H" - shaped frame structure, according to the engineering function and structural requirements, different transverse beam systems and longitudinal beam systems can be further added. The transverse beam system is used to enhance local stiffness, support equipment components, or connect accessory structures, while the longitudinal beam system is used to extend the layout space, adapt to the equipment layout span, or enhance the longitudinal force - transmission capacity. By different combinations and expansions of the transverse beam system and the longitudinal beam system based on the "H" - shaped frame structure, standardized planar layout forms such as "day" - shaped, "you" - shaped, "field" - shaped, "er" - shaped, and "four" - shaped are formed.

[0079] Reference Figures 3 to 7 As shown, schematic diagrams of various standardized planar layout forms are given, which are "day" - shaped, "you" - shaped, "field" - shaped, "er" - shaped, and "four" - shaped in sequence.

[0080] In Figure 3 In the "day" - shaped planar layout form shown, the basic frame structure is composed of side beams symmetrically arranged on the left and right and a main beam connecting the side beams, forming a basic "H" - shaped frame structure. Based on this basic frame, a transverse beam is added at the upper and lower positions respectively, further improving the overall lateral stability of the structure. The overall planar shape of this form is approximately like the character "day", and it is suitable for scenarios where the layout of the hoist support structure is simple and the load - transfer path is clear.

[0081] In Figure 4 In the "you" - shaped planar layout form shown, on the basis of the "H" - shaped frame structure, a longitudinal beam is extended and set at the upper part to expand the longitudinal support range of the structure. The longitudinal beam system, together with the main beam system and the side beam system, forms a closed or semi - closed frame system, and the overall layout is approximately like the character "you", which is beneficial to supporting the equipment layout requirements with a large span or longitudinal distributed loads.

[0082] In Figure 5In the "field" - shaped planar layout shown, this planar layout is based on the "H" - shaped frame structure, and at the same time, two longitudinal beams and two transverse beams are added. This makes the overall structure form a four - part pattern, and the planar shape is approximately like the Chinese character "field". This planar layout has strong overall stability and layout flexibility in all directions and is suitable for the hoist support structure scheme that requires uniform load distribution or dense equipment layout.

[0083] In Figure 6 In the "and" - shaped planar layout shown, this planar layout extends and adds two longitudinal beams at the lower side of the "H" - shaped frame structure, and combines with a transverse beam to form a locally extended structure. The overall structure presents a locally offset layout, and the planar outline is approximately like the Chinese character "and", which is suitable for special engineering scenarios where the space of the support structure is limited or the load distribution is offset, and can balance space utilization and force rationality.

[0084] In Figure 7 In the "four" - shaped planar layout shown, this planar layout conducts asymmetric expansion in both longitudinal and transverse directions on the basis of the "H" - shaped frame structure, sets multiple longitudinal beam systems and transverse beam systems, forms local dense connections and overall partitioned supports, and the overall layout plane is close to the shape of the Chinese character "four". This planar layout is suitable for complex working conditions where the distribution of the support area is uneven or multi - point load support is required, and has good local bearing capacity and overall deformation control effect.

[0085] In addition, for each standardized planar layout type, two support points are respectively arranged along the length direction of each side beam, one pair on the left and one pair on the right, a total of four support points. The support points of the trolley frame are the positions of the walking wheel supports, and the support points of the frame are the positions of the fixed supports, that is, they are used to support the walking wheel supports of the trolley frame or the fixed supports of the frame.

[0086] The cross - sections of the side beams and the main beams can be designed as variable - cross - section fish - belly beams, that is, the cross - section height gradually changes from the support to the mid - span along the length direction to optimize the mid - span bending moment resistance performance. And according to the engineering needs, the cross - section forms of the side beams and the main beams can be selected as I - shaped or box - shaped cross - sections to respectively balance manufacturing economy and overall torsional resistance performance. The cross beams and longitudinal beams, as transverse and longitudinal connection and reinforcement members, usually adopt equal - cross - section I - shaped beam design, and the cross - section dimensions remain the same along the length direction to meet the requirements of local load support and transverse stability.

[0087] The load application points are mainly distributed at the node positions where the main beams and cross beams meet and the middle node positions of the cross beams, which are used to reflect the main application paths of equipment loads, operating loads or additional loads. The specific applied load magnitudes and directions of each load application point are set through parametric input during the modeling process to ensure the consistency between the load application position and the structural topological relationship.

[0088] The side beams usually have a large span in the hoist support structure. Limited by the transportation size requirements, high-strength bolts can be set for segmented connection in the side beam design. Therefore, when performing parametric modeling, segmented connection nodes are set at appropriate positions on the side beams. The segmented connection nodes are usually located in the middle of the beam or at reasonable segmented positions, and are clearly identified by node numbers. During the finite element modeling and solution process, local bending moment and shear force responses can be extracted based on the segmented connection nodes to check the stress conditions and connection strength satisfaction of the high-strength bolt connection parts.

[0089] As Figures 3 to 7 can be seen, each standardized plane layout type is composed of a main beam system, a side beam system, a transverse beam system and a longitudinal beam system, and has corresponding node connection logics and spatial topological characteristics. Further, each standardized plane layout type takes the "H" - shaped frame structure as the core. On this basis, different plane topological characteristics are formed through the addition and combination of the transverse beam system and the longitudinal beam system, so as to adapt to different hoist equipment configurations, load distributions and engineering layout requirements, and provide a standardized and modular design template for the support structure.

[0090] In some exemplary embodiments, a target plane layout type corresponding to the structure layout type parameters can be selected from a plurality of preset standardized plane layout types.

[0091] For example, if the structure layout type parameter of the hoist support structure is the "day" - shaped. First, call the preset standardized plane layout type library, which pre - stores a variety of standardized plane layout types, including the "day" - shaped, "you" - shaped, "field" - shaped, "er" - shaped and "four" - shaped, etc. The system matches the input structure layout type parameter with the layout type identifiers of various standardized plane layout types in the standardized type library. When detecting the standard type identifier corresponding to the "day" - shaped, it is determined that the "day" - shaped layout is the target plane layout type, and this plane layout type is input as a template for subsequent parametric geometric model construction.

[0092] By using the structure layout type parameter as the selection basis, without the need for users to perform cumbersome judgments and manual modeling, the selection judgment of the layout structure can be quickly completed, the pre - configuration efficiency before model construction can be improved, and the consistency between the structure layout logic and the engineering application scenario can be ensured.

[0093] In addition, a standardized plane layout type library needs to be pre - constructed. Exemplarily, engineering examples of multiple hoist support structures can be obtained, and the plane layout characteristics of the bearing beam systems in each engineering example can be extracted. By classifying and standardizing the plane layout characteristics, a variety of standardized plane layout types can be obtained, and then the standardized plane layout type library can be constructed.

[0094] Exemplarily, engineering examples of multiple hoist support structures can be collected, and the planar layout characteristics of the bearing beam systems in each engineering example can be extracted, including key information such as the composition relationship of the foundation frame structure, the addition modes of the transverse beam system and the longitudinal beam system, the node layout, and the component connection methods. Based on the extracted planar layout characteristics, different engineering examples can be classified into several standard type groups according to classification criteria such as structural topology rules, symmetry characteristics, and beam system expansion methods, and the layout characteristics in each type group can be uniformly processed, including standardizing node numbers, normalizing component size ratios, and standardizing connection logics, so as to remove local detail differences and obtain multiple standardized planar layout types including but not limited to "day" shape, "you" shape, "field" shape, "er" shape, and "four" shape. Each standard type has clear structural topology characteristics and expansion rules and can cover the layout requirements of common hoist support structures. Finally, multiple standardized planar layout types are sorted and summarized to construct a standardized planar layout type library, which serves as the retrieval and call basis for selecting the target planar layout type based on the structural layout type parameters in the follow-up.

[0095] To achieve the rapid matching of the planar layout type of the hoist support structure in the parameter input stage, each standardized planar layout type in the standardized planar layout type library can be pre-associated with layout type identifiers, type names, topological structure descriptions, key parameter intervals, etc. When receiving the input of structural layout type parameters, the standard type that matches the input conditions can be quickly retrieved in the standardized planar layout type library based on the layout type identifier or other topological matching rules. If there are multiple eligible types, the best matching type can be further screened according to the structural dimension parameters to ensure that the selected target layout type can accurately reflect the design requirements and working condition adaptability of the hoist support structure.

[0096] The standardized planar layout type library not only has the coverage ability of diversified layout types, but also can support an efficient and accurate layout selection process, providing a reliable data source guarantee for parametric modeling and finite element analysis, and further improving the standardization degree and engineering application flexibility of the hoist support structure design process.

[0097] In step S230, a parametric structural geometric model is constructed by combining the structural parameters and the target planar layout type, and the parametric structural geometric model is discretized into a finite element model containing bearing beam units.

[0098] Among them, the target planar layout type provides the topological framework of the support structure and clarifies the layout logic and node layout method between each beam system. Therefore, based on the selected target planar layout type, the geometric characteristics of components such as main beams, side beams, cross beams, and longitudinal beams can be parametrically defined using the structural dimension parameters in the structural parameters, and a structural wireframe model consistent with the actual layout can be generated, that is, a parametric structural geometric model is obtained.

[0099] It can be understood that parametric structural geometry models can represent the spatial topological relationships of the supporting structure in the form of nodes and line elements. Nodes represent beam connections or locations where forces intersect, while line elements represent the geometric paths and connection states of beam components. Node positions are parametrically defined using structural dimension parameters based on the actual layout dimensions of side beams, main beams, cross beams, and longitudinal beams. Line elements are automatically generated based on the connection relationships between nodes, maintaining the spatial continuity and topological integrity of the load-bearing beam components.

[0100] For example, based on the connection relationships between the various load-bearing beam systems in the target layout, the length, cross-sectional dimensions, and relative positions of each load-bearing beam system can be parametrically defined according to structural dimension parameters to generate a parametric component description set. The parametric definition process can be standardized according to pre-set parametric rules to ensure consistency and automatic generation of modeling results.

[0101] For example, a parametric definition uses the midspan of the main beam as the origin of the geometric coordinate system, establishing a plane rectangular coordinate system with a horizontal x-axis and a vertical y-axis. Specifically, the length of the main beam is set as the horizontal x-axis, and the length of the vertical beam (i.e., longitudinal beam) is set as the vertical y-axis. The overall horizontal dimension of the structure is denoted as L, and the overall vertical dimension is denoted as V. The spatial position, length, and relative relationship of each load-bearing beam system are parametrically defined based on this geometric coordinate system, thus unifying the spatial positioning rules of each node and line element.

[0102] For component parameterization, a unified naming rule is used for description. The component code rule is: main beam (ZL), side beam (BL), cross beam (HL), vertical beam (SL). Figure 8 The I-shaped cross-section structure diagram of the load-bearing beam system shown in FIG. Figure 9 The box-section structure diagram of the load-bearing beam system shown in the figure shows the corresponding cross-sectional dimensions parametrically named as: upper flange width W, lower flange width B, height H, and plate thickness t. The plate thickness can be further subdivided into lower flange thickness t1, upper flange thickness t2, and web thickness tf to reflect the detailed characteristics of the cross-sectional structure. For example, the main beam section width can be named ZL_B, the main beam section height ZL_H, the main beam lower flange thickness ZL_t1, and the main beam web thickness ZL_tf. This parametric naming convention clearly defines the geometric and cross-sectional properties of each beam component, facilitating the subsequent automatic generation of modeling inputs.

[0103] For boundary condition parameters, a unified marking and naming convention is adopted. Figures 3 to 7 As shown, and Figure 3Take this as an example to illustrate the markings. Among them, the basic "H" - shaped frame structure is formed by the side beams BL arranged symmetrically on the left and right and the main beam ZL connecting the side beams. Based on this basic frame, a transverse beam HL is added respectively at the upper and lower positions, and then the "day" - shaped planar layout form is obtained. The load application points are marked with ⊗ and denoted by Fn, such as Figure 3 the load application points F1, F2, etc. in it. The numbers 1 to 7 represent the corresponding numbers of the mid - points of the main beam spans, the intersection points of the bearing beam systems, and the end points of the bearing beam systems. Figure 3 The △ marking in it represents the constraint support position, which is used to indicate the constraint conditions applied to each node. The constraint support points are denoted by Dn, the segmented connection points are denoted by C, and the starting position of the variable cross - section is denoted by B, where n is the serial number (such as F1, D2, C3, B1, etc.). The position of each load application point, constraint support point, or segmented connection point is identified by the horizontal position L and the vertical position V. For example, Figure 3 in it, LF1 represents the horizontal dimension of the position where the load application point F1 is located, VF3 represents the vertical dimension of the position where the load application point F3 is located, LB1 represents the starting position of the variable cross - section of the main beam, VB1 represents the starting position of the variable cross - section of the side beam, VD1 represents the vertical dimension of the position where the constraint support point D1 is located, VC represents the vertical dimension of the position where the segmented connection point C is located, and V1 and V2 respectively represent the vertical dimensions of the positions where the end points 7 and 4 of the bearing beam system are located. Figure 3 Other markings in it and Figures 4 to 7 the descriptions of all markings in it refer to the marking descriptions listed above. Since the naming rules are the same, they are not listed one by one here. Through boundary parameterization definition, not only can the application positions of loads and constraint conditions be standardized, but the internal force responses can also be accurately extracted at the segmented connections and cross - section changes.

[0104] Then, the parameterized component description set is converted into nodes and component line elements corresponding to each bearing beam system in the geometric coordinate system to construct a parameterized structural geometric model. The node is uniquely determined by its horizontal position L and vertical position V, and the line element connects the relevant nodes to form the bearing beam system elements. Thus, the constructed parameterized structural geometric model can accurately reflect the planar topological relationship, component size characteristics, and boundary application conditions of the support structure, and provide a standardized and modular modeling basis for subsequent finite - element discretization and mechanical solution.

[0105] In some example implementations, after the construction of the parametric structural geometric model is completed, each component line element can be converted into a corresponding load-bearing beam unit based on the nodes and component line elements in the parametric structural geometric model according to the preset discrete division rules. For example, according to the preset discrete division rules, each component line element is divided along its length according to the specified step size or node spacing. When dividing, the discrete density can be adaptively determined based on the component category (such as main beam, side beam, cross beam, longitudinal beam) and its size parameters to ensure a higher node density in key stress areas (such as mid-span, near the support, and near the load application point) to enhance the simulation accuracy of the local response. After the division is completed, each line element is subdivided into several load-bearing beam units, and the corresponding nodes are automatically generated at the ends of each unit.

[0106] Next, the node connections between the load-bearing beam elements are established to form a finite element model containing the finite element elements and nodes corresponding to each load-bearing beam system. The node connections are defined according to the topological arrangement of the components in the original parametric structural geometry model, ensuring that the finite element model maintains the connection logic and force paths consistent with the actual structure after discretization. Each component line element corresponds to multiple finite element beam elements, and mechanical continuity and deformation coordination are achieved between elements through shared nodes.

[0107] It can be understood that the final finite element model can fully reflect the topological layout and connection characteristics of each load-bearing beam system of the gate hoist support structure, and at the same time has the node freedom degree definition and unit mechanical properties required for static analysis or dynamic analysis, providing a standardized and high-precision numerical basis for subsequent load application, boundary condition configuration and structural solution analysis.

[0108] In step S240, loads and boundary conditions corresponding to the boundary parameters are applied to the finite element model, and structural mechanics solution calculations are performed to obtain structural calculation results under the target plane layout type.

[0109] In some example embodiments, the concentrated and distributed forces in the load parameters are applied to corresponding nodes and / or component elements in the finite element model, and the constraint condition parameters are mapped into displacement constraints for the corresponding nodes. After the loads and constraints are applied, a static analysis is performed on the finite element model.

[0110] Specifically, during the load application process, concentrated forces or distributed forces are applied to the corresponding nodes and / or component elements in the finite element model according to the definition of the load parameters in the boundary parameters. Concentrated forces are usually applied at the nodes, and distributed forces can be applied to the load-bearing beam elements in a linear or uniform manner. The load magnitude, direction, and application position are implemented according to the detailed definition in the load parameters. For situations where different load types such as equipment loads, operating loads, or construction loads need to be simulated, the system can configure different load conditions according to the load type and action conditions, supporting the superposition or independent solution of multiple conditions.

[0111] During boundary condition configuration, the degrees of freedom at the nodes are restricted according to the definition of the constraint parameters, setting the support boundaries. Support conditions include node displacement constraints and rotational freedom constraints, which can correspond to engineering boundary types such as fixed supports, rolling supports, or sliding supports in actual gate hoist support structures, thus reproducing the structural force boundary.

[0112] After the loads and boundary conditions are applied, the finite element model is statically solved. This process establishes a global stiffness equation system based on the element stiffness matrix and nodal load vectors. Structural response parameters such as nodal displacements, element internal forces, and support reactions are then solved in conjunction with boundary constraints. The solution accurately reflects the deformation state and internal force distribution characteristics of each beam component of the gate hoist support structure under the target layout.

[0113] Ultimately, the structural calculation results are output in the form of structural image data and key numerical data, including but not limited to node displacements, internal forces of each load-bearing beam unit (including axial force, shear force and bending moment distribution), the magnitude and direction of the reaction force of the support node, and the internal force distribution diagram and displacement deformation diagram of each load-bearing beam system under the target plane layout. In addition, a structural calculation report file containing bending moment diagrams, shear force diagrams, stress cloud diagrams, node internal force tables and support reaction force tables can be automatically generated through standardized template replacement.

[0114] This step can accurately simulate the stress state of the structure, identify key components and high-stress areas, and provide a reliable basis for strength verification, design optimization and engineering safety assessment of the supporting structure.
