Description

TECHNICAL FIELD

[0002] The content of this part only provides background information related to the present application, which may not constitute prior art.

[0003] The steel damper of a bridge plays a crucial role in bridge engineering. Its main function is to reduce the vibration of the bridge structure when subjected to external forces (such as earthquakes, wind forces, etc.) by providing motion resistance and consuming kinetic energy. The steel damper fully utilizes the good post-yield properties and plastic deformation capacity of steel, and enters the plastic stage after being stressed, dissipating the energy input by external forces such as earthquakes through plastic deformation. This energy dissipation mechanism effectively reduces the vibration amplitude and frequency of the bridge structure, thereby protecting the main structure of the bridge from damage.

[0004] In the prior art, a Chinese patent with publication number CN105468827A proposes a diagonal bridge seismic damper and its parameter optimization method. Through the diagonal bridge seismic damper, it can effectively dissipate energy when the bridge is subjected to transverse and longitudinal seismic action. It realizes a set of damper that simultaneously controls the response of the bridge under longitudinal and transverse seismic action, improving the seismic efficiency and cost-effectiveness. However, although this scheme has significant advantages in structure, its full performance in practical application still depends on the reasonable configuration of the damper parameters. The existing related technology does not deeply explore or provide a set of parameter optimization method for such diagonal bridge seismic damper, which to some extent limits the maximum performance of the damper.

[0026] Embodiment 1 As shown in Figs. 1-3 The parameter configuration method of the bridge steel damper of the present application comprises the following steps: S1, input the bridge drawing to be processed into the modeling model: according to the size, label information and connection relationship in the bridge drawing to establish the three-dimensional model of the bridge.

[0027] In this step, the bridge design drawings are digitized, and modeling software (such as AutoCAD, Revit, or SolidWorks) is used to construct a three-dimensional model of the bridge based on the dimensions, labeling information, and connection relationships in the drawings. This step is the basis for subsequent analysis, ensuring the accuracy and precision of the analysis. Through the three-dimensional model, the structural layout of the bridge can be visually observed, providing visual support for subsequent analysis.

[0028] Specifically, the steps for establishing a three-dimensional model of the bridge include: S11, according to the labeling information and the preset two-dimensional template of the bridge components, identify each component of the bridge.

[0029] For example, first read the labeling information in the bridge design drawings, which includes the names, dimensions, positions, and other key data of each component of the bridge. At the same time, the system has a series of preset two-dimensional templates of bridge components, which are designed according to common bridge components (such as piers, bridge decks, and beam bodies), with standardized shapes and dimensions. By comparing the labeling information and the preset two-dimensional templates, the system can automatically identify each component of the bridge. This achieves automated identification, improves modeling efficiency, reduces manual intervention, and thus reduces the risk of inaccurate models caused by human error. At the same time, the identified bridge components provide basic data for subsequent three-dimensional modeling.

[0030] S12, according to the size information of each component and the preset three-dimensional template, establish a three-dimensional model of the corresponding size component.

[0031] For example, after identifying each component of the bridge, the system will generate a three-dimensional model of the corresponding size component according to the size information of each component and the preset three-dimensional template. These three-dimensional templates are pre-designed and have a three-dimensional shape and size corresponding to the two-dimensional templates. The system will scale the three-dimensional template according to the actual size of the component to ensure that the generated three-dimensional model conforms to the actual situation. This allows the system to quickly generate three-dimensional models of each component of the bridge, and these models not only have accurate dimensions and shapes, but also maintain consistent proportions with the actual situation. This provides an accurate basis for subsequent model combination and finite element analysis.

[0032] S13, according to the connection relationship, combine all component three-dimensional models to obtain a three-dimensional model of the bridge.

[0033] For example, after obtaining the three-dimensional models of each component of the bridge, the system will combine and cooperate these models according to the connection relationships (such as welding, bolt connection, etc.) in the design drawings. This step needs to consider the spatial position relationship between components, relative angles, and details of the connection method to ensure that the combined model is consistent with the actual situation.

[0034] S2, input the bridge three-dimensional model into the finite element analysis model, the finite element analysis model including a bridge analysis model and a damper analysis model, discretize the bridge three-dimensional model, establish a first motion equation according to each bridge element of the discretization and a preset load, and solve the first motion equation to obtain the deformation and velocity distribution of the bridge.

[0035] Before discretizing the bridge three-dimensional model through the bridge analysis model, it further includes: Comparing the bridge three-dimensional model with each preset bridge standard model, and taking the preset standard model with a similarity greater than a threshold value as the category of the bridge three-dimensional model.

[0036] Specifically, during the comparison process, these standard models are designed based on common bridge types (such as suspension bridges, arch bridges, beam bridges, etc.), which represent the typical structures and characteristics of different types of bridges. The comparison process mainly relies on shape recognition, size matching, and structural feature analysis techniques, and by calculating the similarity between the bridge three-dimensional model and each preset standard model, the system can automatically classify the bridge three-dimensional model into the most similar standard model category, thereby providing more targeted guidance for subsequent load application and discretization processing. At the same time, different categories of bridges have significant differences in structural characteristics and load response, so the classification process helps to ensure the accuracy and applicability of the finite element analysis. In addition, classification also enables the system to more effectively manage and utilize the preset load application strategies and discretization rules, thereby improving analysis efficiency.

[0037] The bridge analysis model applies corresponding loads to the bridge three-dimensional model according to the category of the bridge and the selected load requirements; the bridge analysis model has preset load application strategies for each bridge category, and the load application strategies include multiple load requirement options, each load option has preset load application values at corresponding positions for different bridge categories.

[0038] After determining the category of the bridge three-dimensional model, corresponding loads are applied to the bridge three-dimensional model according to the category of the bridge and the selected load requirements (the load requirements include one of wind load, dead load, live load, and seismic load, etc., which are selected by the user according to design requirements). The bridge analysis model has preset load application strategies for each bridge category, which are developed according to bridge type, purpose, geographical location, and possible environmental conditions, etc. The load application strategies include multiple load requirement options, such as dead load, live load, wind load, temperature load, and seismic load, etc., each load option has preset load application values at corresponding positions for different bridge categories. These values are derived based on extensive engineering practice and theoretical research, aiming to ensure that the finite element analysis can truly reflect the stress condition of the bridge in actual use.

[0039] By precisely applying loads according to the bridge category and load requirements, more accurate and reliable inputs are provided for subsequent discretization processing and motion equation solving. This helps to ensure that the results of finite element analysis can truly reflect the performance and response characteristics of the bridge structure, thereby providing a scientific basis for subsequent design optimization and damper configuration. In addition, the precise application of loads helps to improve the efficiency and accuracy of the analysis, reducing unnecessary calculations and resource waste.

[0040] Discretization of the bridge three-dimensional model is a process of dividing the continuum into a finite number of bridge elements (which can be triangular or quadrilateral elements), each connected by nodes. The purpose of this step is to simplify the complex bridge structure into a series of easily calculated and managed element combinations. Next, according to each discretized bridge element and the preset load conditions (including wind load, dead load, live load, and seismic load, etc.), the system will establish the first motion equation. This equation is a mathematical model that describes the response of the bridge structure under dynamic or static loads, which includes mass matrix, damping matrix, stiffness matrix, and external load vector. By solving this equation, the system can calculate the deformation and velocity distribution of the bridge under given loads, which is an important basis for evaluating the performance of the bridge structure and determining potential weak areas. The first motion equation expression is as follows:

[0041] where, is the mass matrix, is the damping matrix, is the stiffness matrix, is the acceleration of the node, is the velocity of the node, is the displacement vector of the node, is the external load vector.

[0042] S3, screen out the areas with deformation exceeding the first threshold value and velocity exceeding the second threshold value as the installation area; wherein the installation area is the part of the bridge structure that is most susceptible to external forces, which is screened out by deformation and velocity to determine the key position for installing steel dampers to improve structural stability.

[0043] S4, select the target installation area that meets the requirements from multiple installation areas with the maximum efficiency of steel dampers as the target, and the geometric shape, size of the bridge and installation location requirements of the steel damper as the constraint conditions.

[0044] Specifically, the efficiency of the steel damper is maximized, the geometry and size of the bridge, and the installation location requirements of the steel damper (such as space limitations, installation convenience, etc.) are combined, and the target installation area that meets the requirements is selected from multiple installation areas. Ensure the optimal layout of the steel damper in the bridge structure, thereby maximizing its energy dissipation effect.

[0045] S5, according to the deformation and velocity distribution in the target installation area, select a steel damper and its prefabricated damper three-dimensional model that meets the design requirements, and install the damper three-dimensional model in the target installation area. Aims to ensure the perfect match of the steel damper and the bridge structure, and provides an accurate model for subsequent finite element analysis.

[0046] The step of selecting a steel damper that meets the design requirements includes: S51, according to the deformation in the target installation area, calculate the displacement of the bridge; according to the relationship between the damping force, stiffness provided by the steel damper and the displacement of the bridge, determine the first adaptive range of the damping force and stiffness provided by the steel damper.

[0047] Specifically, based on the deformation in the target installation area, the displacement of the bridge under the expected load is calculated through structural mechanics analysis. This displacement value is one of the key parameters for evaluating the performance of the steel damper. Then, using the basic mechanical properties of the steel damper, i.e. the damping force and stiffness it can provide, and the relationship between these properties and the displacement of the bridge, the adaptive range of the steel damper is preliminarily determined. Thus, the steel damper candidate products that can provide appropriate damping force and stiffness are preliminarily screened, providing a basis for more detailed screening in subsequent steps.

[0048] S52, according to the velocity distribution in the target installation area, obtain the response characteristics of the bridge under dynamic load, and according to the relationship between the response characteristics and the energy absorption and dissipation velocity, determine the second adaptive range of the energy absorption and dissipation velocity of the steel damper; Specifically, considering the response characteristics of the bridge under dynamic load, these characteristics include the vibration frequency, vibration amplitude, vibration mode (such as torsion, lateral bending, etc.) and stress distribution of the bridge. These information is usually obtained through historical monitoring data or numerical simulation, i.e. through the relationship between the velocity and response characteristics at the same location in the historical data, thereby obtaining the response characteristics of the bridge under different velocities. Based on these response characteristics, combined with the relationship between energy absorption and dissipation velocity, the performance of different steel dampers in the dynamic response of the bridge can be evaluated, and the second adaptive range of the energy absorption and dissipation velocity of the steel damper is determined accordingly. It can more comprehensively consider the behavior of the bridge under dynamic load, thereby selecting the steel damper that can effectively absorb and dissipate vibration energy.

[0049] S53, selecting a steel damper that meets the first and second adaptation ranges in a pre-set database. This enables quick and accurate selection of the best option that meets the bridge structure requirements from numerous steel damper products. Not only does this improve the efficiency of the selection process, but it also ensures that the performance and quality of the selected damper meet the design requirements. This helps to improve the overall performance and safety of the bridge structure and prolong its service life.

[0050] S6, using the deformation and velocity distribution of the bridge in the target installation area where the damper three-dimensional model is installed as the applied load, discretizing the damper three-dimensional model using the damper analysis model, establishing a second motion equation based on the parameters of each discrete damper element and the applied load, solving the second motion equation to obtain the deformation and velocity distribution of the steel damper; calculating the corresponding hysteresis curve area in multiple directions based on the deformation and velocity distribution of the steel damper, and screening out the parameters corresponding to the pre-set hysteresis curve area range as the configuration parameters of the steel damper.

[0051] Specifically, in the finite element analysis of the damper analysis model, the second motion equation is usually used to describe the dynamic behavior of the damper. This equation can be established based on Newton's second law and the mechanical properties of the damper. Assuming that the damper is discretized into n individual damper elements, the second motion equation can be expressed as:

[0052] where, is the mass of each damper element, is the displacement of each damper element, is the velocity of each damper element, is the acceleration of each damper element, is the external force (or load) of each damper element, is the damping coefficient, is the stiffness coefficient.

[0053] The hysteresis curve is a curve that describes the relationship between force and displacement of the damper under cyclic loading. The hysteresis curve area is usually used to evaluate the energy dissipation capacity of the damper. Assuming that the damper is subjected to cyclic loading in multiple directions (such as x, y, z directions), and the relationship between force and displacement in each direction can be expressed as , then the hysteresis curve area can be calculated by integration:

[0054] where, represents the integral over the cycle path, is the hysteresis curve area, represents the direction, For the force and displacement relationship in each direction.

[0055] By screening out the parameters corresponding to the preset hysteretic curve area range as the configuration parameters of the steel damper, it can be ensured that the damper has the best energy dissipation effect in actual application. Through fine finite element analysis and parameter screening, the performance of the steel damper is maximized.

[0056] After completing step S6, in order to ensure the accuracy and effectiveness of the selected parameters, further verification is needed. The verification is carried out by a simulation model, which is based on a large amount of historical bridge data as a training set, trained and optimized by a neural network model. These historical data cover the response characteristics of the bridge under different working conditions, including displacement, velocity, acceleration, stress distribution, etc., providing rich training materials for the simulation model. Through the learning ability of the neural network, the simulation model can capture the complex dynamic behavior of the bridge structure and accurately simulate it. After screening out the configuration parameters that meet the preset hysteretic curve area range, these parameters are applied to the configuration of the steel damper, and the configured steel damper is substituted into the simulation model for verification. This verification process aims to evaluate the performance of the selected configuration parameters in the actual bridge structure, including their influence on the dynamic response of the bridge, the effect of energy absorption and dissipation, etc. Through the simulation of the simulation model, the vibration characteristics of the bridge under the configuration parameters and the effect of the steel damper in it can be observed directly.

[0057] If the verification result of the simulation model is "yes", that is, the selected configuration parameters can effectively improve the dynamic response of the bridge and meet the design requirements, then the configuration parameters are used for subsequent engineering implementation. This means that the selected parameters have passed strict verification and evaluation, and have reliability and practicality.

[0058] However, if the verification result is "no", that is, the selected configuration parameters fail to achieve the expected effect, the system will issue a prompt that the configuration parameters need to be reselected or further adjusted. This prompt mechanism ensures our flexibility and accuracy in the process of selecting configuration parameters, avoiding potential risks caused by improper parameters.
