Description

Technical Field

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

[0002] In existing water conservancy and hydropower projects, hoists, as the main mechanical devices, are widely used for the lifting control of gates. Their structural design is directly related to the safety and reliability of project operation. Among them, winch hoists are commonly used in large and medium-sized hydraulic structures due to their simple structure and strong load-bearing capacity. The trolley frame or machine frame, as an important structural unit for bearing the lifting load, undertakes the installation support and mechanical transmission of key equipment such as fixed pulley groups, drum devices, and reducers. Therefore, the design and verification of the trolley frame or machine frame structure have always been the core link in the structural analysis of hoists.

[0003] In engineering practice, the plane structure simplified analysis method is usually used to analyze the stress of the trolley frame or machine frame. This type of method mostly takes a single beam as the modeling object, ignoring the spatial coupling relationship between the beam systems in the overall frame structure. To meet the engineering accuracy requirements, it is also necessary to independently check each beam member separately, which not only has a cumbersome calculation process but also easily ignores 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 equipment loads, that is, it is impossible to accurately reflect the internal force distribution at the segmented joints and variable cross-section beams, and there are certain calculation deviations, 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 hoist support structures.

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

[0039] An embodiment of the present disclosure provides a finite element calculation method for a hoist structure. Referring to Figure 2 as shown, this method may include steps S210 to S240: Step S210: Obtain the structural parameters and boundary parameters of the hoist support structure; Step S220: Based on the structural parameters, select a target planar layout type from a variety of preset standardized planar layout types; Step S230: Combine the structural parameters and the target planar layout type to construct a parametric structural geometric model, and discretize the parametric structural geometric model into a finite element model including load-bearing beam elements; Step S240: Apply loads and boundary conditions corresponding to the boundary parameters to the finite element model, and perform structural mechanics solution calculations to obtain the structural calculation results under the target planar layout type.

[0040] Executing the finite element calculation method for the hoist structure provided by the present disclosure can realize the full-process automatic processing from the input of structural parameters and boundary parameters to modeling, solution, and output. On the one hand, by introducing standardized planar layout types, the modular reuse ability of structural layouts under different engineering conditions is improved, and manual layout judgment errors are avoided; on the other hand, during the structural modeling process, the target layout type and structural dimension parameters act 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 missing beam system coupling in simplified modeling; on the other hand, after discretizing the parametric structural geometric model into a finite element model including load-bearing beam elements, combined with the accurate application of loads and constraint conditions in the boundary parameters, the actual load transfer path in the structure can be restored, the ability to capture the mechanical response of key parts can be improved, the structural deviation in traditional calculations can be reduced, and the automatic, high-precision, and standardized operation of structural analysis can be supported.

[0041] Next, the finite element calculation method for the hoist structure in this exemplary embodiment will be described in detail.

[0042] In step S210, the structural parameters and boundary parameters of the hoist support structure are obtained.

[0043] A hoist, also known as a hydraulic hoisting device, refers to a complete set of mechanical devices used to lift or rotate a hydraulic gate to control the on-off of water flow in the water passage section, regulate the water level, or store water. The types of hoists include but are not limited to winch hoists, hydraulic hoists, screw hoists, mobile hoists, etc.

[0044] In the exemplary embodiments of the present disclosure, a hoisting type hoist is taken as an example for illustration. The hoist support structure refers to a load-bearing frame that bears key components such as a hoisting device, a speed reducer, a fixed pulley set, etc., and transfers the operating load to the lower foundation structure or fixed anchorage part. This support structure is usually a trolley frame (also known as a carriage frame) or a machine frame, and is the most core mechanical load-bearing unit in a hoisting type hoist. The hoist support structure is composed of multiple beam system components, undertakes important installation, connection and force transmission tasks in the hoist, and its structural performance is directly related to the safety and stability of the overall operation of the hoist.

[0045] Among them, the structural parameters of the hoist support structure are used to characterize the basic characteristics of the hoist support structure in terms of geometric layout and dimensional structure. In the exemplary embodiments 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, and serve 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 component length, cross-sectional dimensions, arrangement layers, and the relative position relationship between components, etc., and are the key inputs for generating a parametric structural geometric model.

[0046] The boundary parameters of the hoist support structure are used to define the load action 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, and are 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 degree of freedom and its corresponding support type, such as fixed, sliding or hinged connection methods.

[0047] This step can achieve the comprehensive information acquisition of the hoist support structure in two dimensions of geometric configuration and force boundary, and provide a complete and standardized engineering input basis for layout type selection, parametric modeling and finite element solution.

[0048] In step S220, based on the structural parameters, a target planar layout type is selected from a plurality of preset standardized planar layout types.

[0049] In this step, the layout structure that is most suitable for the current engineering design requirements can be selected from a plurality of preset structural layout templates through structural parameters. In the exemplary implementation of the present disclosure, the standardized plane layout type is a typical topological structure summarized and sorted according to the common supporting structure forms in hydraulic gate hoist engineering, which is used to provide a structural topological basis in the modeling process. Exemplarily, it can include the plane layout types of "日" shape, "由" shape, "田" shape, "而" shape and "四" shape. Of course, other types of configurations can also be included, which is not limited in the present disclosure. Among them, the plane layout types of "日" shape, "由" shape and "田" shape are common load-bearing structure arrangements for single-hanging-point lifting mechanisms, and the plane layout types of "而" shape and "四" shape are common load-bearing structure arrangements for double-hanging-point lifting mechanisms.

[0050] It should be noted that each standardized plan layout type is composed of a basic frame structure and a transverse beam system and a longitudinal beam system connected to the basic frame structure. The basic frame structure, as a rigid supporting unit of the entire structure, determines the basic form and overall stability of the standardized plan layout type.

[0051] 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 arranged between the two side beams and connected laterally. This structure forms a basic "H"-shaped frame structure, which is a load-bearing core unit commonly used in the support structure of the winch-type gate hoist. The side beam system is mainly responsible for vertical load-bearing and stability control, while the main beam system plays the role of connecting the side beams, distributing the load and improving the lateral stiffness.

[0052] On the basis of the "H"-shaped frame structure, different transverse beam systems and longitudinal beam systems can be further added according to the engineering functions and structural requirements. The transverse beam system is used to improve local rigidity, support equipment components or connect auxiliary structures, while the longitudinal beam system is used to extend the layout space, adapt to the equipment layout span or improve the longitudinal force transmission capacity. Through different combinations and expansions of the transverse beam system and the longitudinal beam system on the basis of the "H"-shaped frame structure, standardized plane layout types such as "日" shape, "由" shape, "田" shape, "而" shape and "四" shape are formed.

[0053] refer to Figures 3 to 7 As shown, schematic diagrams of various standardized plan layout types are given, namely, the "日" type, the "由" type, the "田" type, the "而" type and the "四" type.

[0054] exist Figure 3In the "日"-shaped plane layout shown, the basic frame structure is composed of side beams arranged symmetrically on the left and right and main beams 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 to further improve the overall lateral stability of the structure. The overall plane shape of this type is similar to the "日" character, which is suitable for scenes where the support structure of the hoist is simple and the load transfer path is clear.

[0055] exist Figure 4 In the "You"-shaped plan layout shown, a longitudinal beam is extended from the upper part on the basis of the "H"-shaped frame structure to expand the longitudinal support range of the structure. The longitudinal beam system, the main beam system and the side beam system together form a closed or semi-closed frame system. The overall layout is similar to the "You" shape, which is conducive to supporting the layout requirements of equipment with larger spans or longitudinal distributed loads.

[0056] exist Figure 5 In the "田"-shaped plane layout shown, two longitudinal beams and two transverse beams are added to the "H"-shaped frame structure, so that the overall structure forms a four-part pattern, and the plane shape is similar to the "田". This plane layout has strong overall stability and layout flexibility in all directions, and is suitable for the support structure of the gate hoist that requires uniform load distribution or dense equipment layout.

[0057] exist Figure 6 In the "而"-shaped plane layout shown, two longitudinal beams are extended from the lower side of the "H"-shaped frame structure, and a cross beam is combined to form a local expansion structure. The overall structure presents a local offset layout, and the plane shape is similar to the "而" character. It is suitable for special engineering scenarios where the supporting structure space is limited or the load distribution is offset, and can take into account both space utilization and force rationality.

[0058] exist Figure 7 In the "four"-shaped plane layout shown, this plane layout type is based on the "H"-shaped frame structure and is asymmetrically expanded in both the vertical and horizontal directions. Multiple longitudinal beams and transverse beams are set to form local dense connections and overall partitioned support. The overall layout plane is close to the "four" shape. This plane layout type is suitable for complex working conditions where the support area is unevenly distributed or multiple-point load support is required, and has good local bearing capacity and overall deformation control effect.

[0059] In addition, for each standardized plane layout type, each side beam is provided with two support points along the length direction, with a pair on each side, for a total of four support points. The support point of the trolley frame is the travel wheel support position, and the support point of the frame is the fixed support position, that is, it is used to support the travel wheel support of the trolley frame or the fixed support of the frame.

[0060] The cross-sections of the side beams and 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 main beams can choose I-shaped or box-shaped cross-sections to take into account the manufacturing economy and the overall torsional resistance performance respectively. The cross beams and longitudinal beams, as transverse and longitudinal connection and reinforcement members, usually adopt the design of equal cross-section I-shaped beams, and the cross-section dimensions remain the same along the length direction to meet the requirements of local load support and transverse stability.

[0061] The load application points are mainly distributed at the node positions where the main beam and the cross beam meet and the middle node positions of the cross beam 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.

[0062] The side beams usually have a large span in the hoist support structure, and limited by the transportation dimension requirements, high-strength bolts can be set for segmented connection in the side beam design. Therefore, during parametric modeling, segmented connection nodes are set at appropriate positions of the side beam. 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, the 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.

[0063] It can be seen from Figures 3 to 7 that 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, and 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.

[0064] In some exemplary embodiments, a target plane layout type corresponding to the structural layout type parameters can be selected from a plurality of preset standardized plane layout types.

[0065] For example, if the structural layout type parameter of the gate hoist support structure is a "日" shape. First, call the preset standardized plane layout type library, which pre-stores a variety of standardized plane layout types, including "日" shape, "由" shape, "田" shape, "而" shape, and "四" shape. According to the input structural layout type parameters, the system matches the parameters with the layout type identifiers of various standardized plane layout types in the standardized type library. When the standard type identifier corresponding to the "日" shape is detected, the "日" shape layout is determined as the target plane layout type, and the plane layout type is used as a template input for the subsequent parametric geometric model construction.

[0066] By taking the structural layout type parameters as the basis for selection, the selection of the layout structure can be quickly completed without the need for users to make tedious judgments and manual modeling, thereby improving the efficiency of pre-configuration before model building and ensuring the consistency of the structural layout logic with the engineering application scenario.

[0067] In addition, a standardized plan layout type library needs to be built in advance. For example, multiple engineering examples of gate hoist support structures can be obtained, and the plan layout features of the load-bearing beam system in each engineering example can be extracted. By classifying and standardizing the plan layout features, a variety of standardized plan layout types can be obtained, and then a standardized plan layout type library can be built.

[0068] For example, multiple engineering examples of gate hoist support structures can be collected to extract the plane layout features of the load-bearing beam system in each engineering example, including the composition relationship of the basic frame structure, the additional mode of the transverse beam system and the longitudinal beam system, the node layout and the component connection method and other key information. Based on the extracted plane layout features, different engineering examples can be classified into several standard type groups according to the classification standards such as structural topological laws, symmetry characteristics and beam system expansion methods, and the layout features in each type group are uniformly processed, including node number standardization, component size ratio normalization and connection logic normalization, so as to remove local detail differences, and obtain a variety of standardized plane layout types including but not limited to "日" type, "由" type, "田" type, "而" type and "四" type. Each standard type has clear structural topological characteristics and expansion rules, and can cover the layout requirements of common gate hoist support structures. Finally, a variety of standardized plane layout types are sorted and summarized to form a standardized plane layout type library, which serves as the basis for subsequent retrieval and calling when selecting the target plane layout type based on the structural layout type parameters.

[0069] To achieve a rapid match of the plane layout type during the parameter input stage of the hoist support structure, each standardized plane layout type in the standardized plane layout type library can be pre-associated with layout type identifiers, type names, topological structure descriptions, key parameter ranges, etc. When receiving the input of structure layout type parameters, based on the layout type identifier or other topological matching rules, the standard type that matches the input conditions can be quickly retrieved from the standardized plane layout type library. 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.

[0070] The standardized plane layout type library not only has the ability to cover diverse layout types but also supports an efficient and accurate layout selection process, providing a reliable data source guarantee for parametric modeling and finite element analysis, and further enhancing the standardization degree and engineering application flexibility of the hoist support structure design process.

[0071] In step S230, a parametric structural geometric model is constructed by combining the structural parameters and the target plane layout type, and the parametric structural geometric model is discretized into a finite element model containing load-bearing beam elements.

[0072] Among them, the target plane layout type provides the topological framework of the support structure, clarifying the layout logic and node layout method between each beam system. Therefore, based on the selected target plane 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, generating a structural wireframe model consistent with the actual layout, that is, obtaining the parametric structural geometric model.

[0073] It can be understood that the parametric structural geometric model can represent the spatial topological relationship of the support structure in the form of nodes and line elements. Among them, nodes are used to express the positions where beam systems are connected or forces converge, and line elements are used to express the geometric paths and connection states of beam system components. The positions of the nodes are parametrically defined by the structural dimension parameters according to the actual layout dimensions of the side beams, main beams, cross beams, and longitudinal beams, and the line elements are automatically generated according to the connection relationship between the nodes, maintaining the spatial continuity and topological integrity of the load-bearing beam components.

[0074] Exemplarily, based on the connection relationship between each load-bearing beam system in the target plane layout type, the lengths, cross-sectional dimensions, and relative positions of each load-bearing beam system can be parametrically defined according to the structural dimension parameters, obtaining a parametric component description set. Among them, the parametric definition process can be standardized and described according to the preset parametric rules to ensure the consistency and automatic generation of the modeling results.

[0075] For example, the parametric definition takes the midpoint of the main beam span as the origin of the geometric coordinate system, and establishes a plane rectangular coordinate system with a horizontal x-axis and a vertical y-axis. Specifically, the length direction of the main beam is set as the horizontal x-axis, and the length direction of the vertical beam (i.e., longitudinal beam) is set as the vertical y-axis. The overall lateral dimension of the structure is denoted as L, and the overall vertical dimension is denoted as V. The spatial positions, lengths, and relative relationships of each load-bearing beam system are parametrically defined based on this geometric coordinate system, thereby unifying the spatial positioning rules for each node and line element.

[0076] For component parameterization, a unified naming rule is adopted for description. Among them, the component code rule is: main beam (ZL), side beam (BL), cross beam (HL), vertical beam (SL). Refer to Figure 8 the schematic structural diagram of the I-shaped cross-section form of the load-bearing beam system shown in Figure 9 and the schematic structural diagram of the box-shaped cross-section form of the load-bearing beam system shown in

[0077] For boundary condition parameters, a unified marking and naming rule is adopted. Refer to Figures 3 to 7 shown, and take Figure 3 as an example to illustrate the markings therein. 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 at the upper and lower positions respectively, and the "day"-shaped planar layout type is obtained. The load application points are identified with the ⊗ mark and denoted by Fn, such as Figure 3 the load application points F1, F2, etc. in Figure 3 The △ mark in Figure 3In it, LF1 represents the lateral 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 point 7 of the load-bearing beam system and the end point 4 of the load-bearing beam system are located. Figure 3 Other markings in it, as well as Figures 4 to 7 The descriptions of all markings in it refer to the marking descriptions listed above. Due to the same naming rules, they will not be listed one by one here. Through boundary parameterization definition, not only can the application positions of loads and constraint conditions be standardized, but also the internal force responses can be accurately extracted at the segmented connections and cross-section changes.

[0078] Then, convert the parameterized component description set into nodes and component line elements corresponding to each load-bearing beam system in the geometric coordinate system to construct a parameterized structural geometric model. The node is uniquely determined by its lateral position L and vertical position V, and the line element connects the relevant nodes to form the load-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.

[0079] In some exemplary embodiments, after the construction of the parameterized structural geometric model is completed, based on the nodes and component line elements in the parameterized structural geometric model, each component line element can be converted into a corresponding load-bearing beam element according to a preset discrete division rule. For example, according to the preset discrete division rule, each component line element is divided along its length direction according to a specified step size or node spacing. When dividing, the discrete density can be adaptively determined according to the component category (such as main beam, side beam, cross beam, longitudinal beam) and its size parameters to ensure a higher node density in the key stress areas (such as mid-span, near the support, near the load application point) to enhance the simulation accuracy of local responses. After the division is completed, each line element segment is subdivided into several load-bearing beam elements, and corresponding nodes are automatically generated at the ends of each element.

[0080] Next, establish the node connection relationships between each load-bearing beam element to form a finite element model including finite element elements and nodes corresponding to each load-bearing beam system. The node connection relationships are defined according to the topological layout between the components in the original parameterized structural geometric model to ensure that the finite element model still maintains the connection logic and force path consistent with the actual structure after discretization. Each component line element corresponds to multiple finite element beam elements, and the mechanical continuity and deformation coordination between the elements are realized through shared nodes.

[0081] It can be understood that the finally formed finite element model can completely reflect the topological layout and connection characteristics of each load-bearing beam system of the hoist support structure, and at the same time has the definition of node degrees of freedom and element mechanical properties required to meet static analysis or dynamic analysis, providing a standardized and high-precision numerical basis for subsequent load application, boundary condition configuration and structural solution analysis.

[0082] In step S240, load and boundary conditions corresponding to the boundary parameters are applied to the finite element model, and structural mechanics solution calculations are performed to obtain the structural calculation results under the target planar layout type.

[0083] In some exemplary embodiments, the concentrated force and distributed force in the load parameters are applied to the corresponding nodes and / or member elements in the finite element model, and the constraint condition parameters are mapped to displacement constraints on the corresponding nodes. After the application of the load and constraints is completed, a static solution analysis is performed on the finite element model.

[0084] Specifically, during the load application process, according to the definition of the load parameters in the boundary parameters, the concentrated force or distributed force is applied to the corresponding nodes and / or member elements in the finite element model. The concentrated force is usually applied at the nodes, and the distributed force can be applied to the load-bearing beam elements in a linear or uniform manner. The magnitude, direction and application position of the load are executed 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 types and working conditions, and support multi-condition superposition or independent solution.

[0085] During the boundary condition configuration process, according to the definition of the constraint condition parameters, the degrees of freedom at the nodes are restricted to set the support boundary. The support conditions include node displacement constraints, rotational degree of freedom constraints, etc., which can correspond to engineering boundary types such as fixed supports, rolling supports or sliding supports in the actual hoist support structure, and complete the restoration expression of the structural force boundary.

[0086] After the application of the load and boundary conditions is completed, a static mechanics solution of the finite element model is executed. During the solution process, a global stiffness equation system can be established based on the element stiffness matrix and the node load vector, and the structural response parameters such as node displacements, element internal forces and support reactions are solved in combination with the boundary constraint conditions. The solution results can accurately reflect the deformation state and internal force distribution characteristics of each beam system component of the hoist support structure under the target planar layout type.

[0087] Finally, 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 element (including axial force, shear force, and moment distribution), reaction force magnitudes and directions of support nodes, and internal force distribution diagrams and displacement deformation diagrams of each load-bearing beam system under the target plane layout type. Moreover, a structural calculation report file containing moment diagrams, shear force diagrams, stress nephograms, node internal force tables, and support reaction force tables can be automatically generated through the standardized template replacement method.

[0088] This step can accurately simulate the stress state of the structure, identify key components and high-stress areas, and provide a reliable basis for the strength check, design optimization, and engineering safety assessment of the support structure.
