Abstract
Description
Technical Field
[0001] The invention relates to the technical field of energy dissipation and shock absorption, and in particular to a test method for the response of a shock-absorbing and isolating device under the action of seismic waves in a structural system. Background Art
[0002] Since the 1960s, a series of fruitful research results have been achieved in the field of earthquake resistance of building structures, which has promoted the evolution of earthquake resistance theory and made the basic design concept of "strong earthquake resistance" possible. In the past 30 years, while the seismic performance of building structures in earthquake zones has been greatly improved, the earthquake damage suffered by building structures has shown strong randomness. The achievement rate of the three-level seismic resistance goals of "small earthquakes are not damaged, medium earthquakes are repairable, and strong earthquakes are not collapsed" is low, and the post-earthquake repairability of structures is poor. Therefore, the risks and complexity of urbanization and modernization in my country are high, resulting in new situations and new problems in seismic design work, which has promoted the continuous advancement of research on the theory and technology of earthquake reduction and disaster reduction of building structures.
[0003] Structural seismic isolation technology is a key technology for passive seismic control of building structures developed in recent years, and plays an important role in seismic and disaster reduction of building structures. Both structural energy dissipation and seismic isolation structures "soften" structural components or "disconnect" structural connections to make them "undamaged in small earthquakes, repairable in medium earthquakes, and uncollapsed in large earthquakes". The damaged parts of the structure are not the key positions of the structure's load-bearing capacity, so that the "swaying" performance of the structure under medium and strong earthquakes will not affect the use of the structural function, and it is easy to repair after a strong earthquake, truly avoiding "destructive damage".
[0004] By setting an energy dissipation and shock absorption device in the building structure, it is equivalent to adding a new stiffness Kf to the original stiffness of the building structure, and the energy dissipation and shock absorption device has the characteristics of relatively small yield strength, obvious hysteresis performance after yielding, and good elastic-plastic performance, so that the overall stiffness of the building structure is reduced and easy to yield. In the prior art, when installing the energy dissipation and shock absorption device, it is necessary to test the energy dissipation and shock absorption device through seismic waves to test the vibration energy dissipation effect of the energy dissipation and shock absorption device. When testing the energy dissipation and shock absorption equipment, the energy dissipation and shock absorption device needs to be tested repeatedly, but the existing seismic wave test can only experiment with a single seismic wave. If different data needs to be obtained, the seismic wave needs to be replaced. At the same time, too many tests will damage the energy dissipation and shock absorption device, affecting subsequent tests. Summary of the invention

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0022] Example:
[0023] like Figure 1 As shown, a test method for the response of a seismic isolation device under the action of seismic waves in a structural system comprises the following steps:
[0024] Obtaining a seismic wave parameter model, substituting data in the seismic wave parameter model into a seismic experiment simulation device, and starting the seismic experiment simulation device to perform reciprocating motion in a set direction;
[0025] The displacement parameters generated by the reciprocating motion are compared and matched with the data in the seismic wave parameter model through the built-in sensor of the seismic experiment simulation device, and the displacement parameter data of the seismic experiment simulation device are adjusted in real time until the error value between the displacement parameter data and the displacement parameter data in the seismic wave parameter model is within the set threshold;
[0026] Input the adjusted displacement parameter data into the test equipment of the seismic isolation device, establish a seismic wave simulation database in the test equipment, mark the input displacement parameter data in the seismic wave simulation database, place the seismic isolation device on the test equipment, start the test equipment and select any displacement parameter in the seismic wave simulation database for testing;
[0027] The test parameters of the seismic isolation device are recorded, and the time and displacement change control curve diagram and the displacement and force change test curve diagram of each test parameter are synchronously recorded and stored. After traversing the displacement parameters in the seismic wave simulation database, the test results of the seismic isolation device are formed, and the test results are output and displayed.
[0028] This test method is designed to evaluate the response characteristics of seismic isolation devices in structural systems under the action of seismic waves. Its working principle and process can be divided into several key steps to ensure accurate simulation and evaluation of the performance of seismic isolation devices. First of all, the starting point of the test is to obtain a seismic wave parameter model. This model contains various parameters related to seismic waves, such as frequency, amplitude, and waveform, which are the basis for subsequent tests. By analyzing actual earthquake records, researchers can establish an effective seismic wave parameter model to ensure that it can truly reflect possible earthquake fluctuations.
[0029] The data in the acquired seismic wave parameter model is imported into the seismic experiment simulation device. The device is a device specially designed to simulate the action of seismic waves and can reciprocate in a set direction. The key to this step is to ensure that the motion characteristics of the seismic experiment simulation device can match the seismic wave parameter model so that the real seismic fluctuations can be accurately reproduced in the experiment. After the seismic experiment simulation device is started, it will reciprocate according to the set parameters to simulate the actual action of seismic waves.
[0030] During the reciprocating motion, the sensors built into the earthquake experiment simulation device will monitor and record the generated displacement parameters in real time. These displacement data will be compared and matched with the displacement parameters in the seismic wave parameter model. In order to ensure the accuracy of the experiment, the system will automatically make real-time adjustments. If errors are found between the displacement parameter data and the data in the seismic wave parameter model, the relevant parameters will be adjusted until the error value is controlled within the set threshold. This process is an important link to ensure that the experimental simulation is consistent with the actual earthquake fluctuations, and can effectively improve the reliability of the test data.
[0031] After the displacement parameter data has been adjusted, the next step is to input these corrected displacement parameter data into the test equipment of the seismic isolation device. In the test equipment, a seismic wave simulation database will be established to store and manage the input displacement parameter data and mark them. This database is established to facilitate the selection and management of subsequent experiments. Then, the seismic isolation device is placed on the test equipment and the test equipment is started. The researchers can select any displacement parameter from the seismic wave simulation database for testing.
[0032] When testing the seismic isolation device, the system will record the relevant test parameters, including displacement changes, force value changes, etc. The parameters and data of each test will be plotted into a control curve for easy analysis and comparison. Specifically, the time and displacement change control curve, as well as the displacement and force value change test curve, will be recorded synchronously. These curves can intuitively reflect the dynamic response characteristics of the seismic isolation device under the action of seismic waves.
[0033] After all displacement parameters have been tested, the system will generate test results for the seismic isolation device. The test results will be collated and displayed, and researchers can conduct further analysis and summary based on these results. This process can not only help evaluate the performance of the seismic isolation device, but also provide valuable data support for subsequent design improvements.
[0034] This test method forms a complete workflow through a series of steps, from obtaining the seismic wave parameter model, setting up and adjusting the seismic experimental simulation device, to placing the seismic isolation device, recording the test parameters, and finally outputting and displaying the final results. This process ensures that the response of the seismic isolation device under the simulated seismic wave can be accurately evaluated, providing an important experimental basis for the seismic design of the structural system.
[0035] After obtaining the seismic wave parameter model, any seismic wave parameter model is selected and substituted into the seismic experiment simulation device. The seismic wave parameter model is composed of a number of seismic wave waveform data, and the seismic wave waveform data includes shear wave data and longitudinal wave data. The shear wave data and longitudinal wave data are integrated into the seismic wave parameter model. The seismic wave waveform data is selected by inputting it into the seismic experiment simulation device; the seismic experiment simulation device converts the shear wave data and longitudinal wave data of the selected seismic wave parameter model into acceleration, velocity and displacement data models under the action of seismic waves, and stores them in an internal storage module of the seismic experiment simulation device. The seismic experiment simulation device is internally provided with sensors for detecting the acceleration, velocity and displacement of seismic waves under the action of seismic waves.
[0036] Compared with the existing technology, this technical solution shows obvious innovation and advantages in the acquisition and application of seismic wave parameter models, which are mainly reflected in data integration, simulation accuracy and real-time detection. First of all, in the construction of the seismic wave parameter model, this technical solution forms a comprehensive seismic wave parameter model by integrating shear wave data and longitudinal wave data. This data integration method enables the model to more accurately reflect the actual characteristics of seismic waves, while the existing technology usually adopts a single data source in this regard, which may lead to an incomplete understanding of the characteristics of seismic waves, thereby affecting subsequent experimental results and analysis. Therefore, the practice of integrating shear wave and longitudinal wave data makes this technical solution more realistic and reliable when simulating seismic waves.
[0037] After receiving the selected seismic wave parameter model, the earthquake experiment simulation device can convert the shear wave and longitudinal wave data into acceleration, velocity and displacement data models and store them in the internal storage module. The innovation of this process is that by converting and storing multiple physical quantities (acceleration, velocity and displacement), the experimental device has stronger data processing capabilities and flexibility. In contrast, existing technologies often only focus on a specific output parameter and lack the ability to comprehensively process multiple response data, which limits the analysis and application of experimental results.
[0038] The technical solution also sets up sensors inside the earthquake experiment simulation device to detect acceleration, velocity and displacement under the action of seismic waves. The advantage of this design is that it can achieve real-time monitoring and feedback, so that the response to the action of seismic waves during the experiment can be recorded and analyzed in the first time, so as to adjust the experimental parameters in time. This real-time detection capability is relatively lacking in the existing technology. Many systems rely on post-data analysis for monitoring, resulting in insufficient response to emergencies, which may affect the effectiveness and accuracy of the experiment.
[0039] The seismic experiment simulation device is provided with a matching module, through which the displacement parameters generated by the reciprocating motion are compared with the data in the seismic wave parameter model, and the shear wave data and the longitudinal wave data of the seismic wave parameter model whose error value with the displacement parameters generated by the reciprocating motion is within a certain threshold are screened out; after the comparison module compares the shear wave data and the longitudinal wave data of the seismic wave parameter model whose error value with the displacement parameters is within a certain threshold, the corresponding maximum acceleration value and the minimum acceleration value are determined, and output to the seismic experiment simulation device, and the maximum acceleration value and the minimum acceleration value are set as the movable range of the displacement parameters generated by the reciprocating motion, and the shear wave data and the longitudinal wave data of the seismic wave parameter model whose error value is within a certain threshold are continuously adjusted by the processor in the seismic experiment simulation device, and the movable range of the displacement parameters generated by the reciprocating motion is adjusted until the maximum acceleration value and the minimum acceleration value of the shear wave data and the longitudinal wave data of the seismic wave parameter model whose error value is within a certain threshold are consistent with those of the displacement parameters generated by the reciprocating motion.
[0040] Compared with the existing technology, it shows significant advantages and innovations, mainly reflected in the application of matching modules, error adjustment mechanism and acceleration range setting. First, a matching module is introduced in the technical solution, through which the displacement parameters generated by reciprocating motion are compared with the data in the seismic wave parameter model. This design not only improves the efficiency of data processing, but also can screen out the transverse wave and longitudinal wave data whose error values of the displacement parameters generated by reciprocating motion are within a certain threshold in real time. This process is usually more complicated in the existing technology, and many systems lack an effective matching mechanism, resulting in inaccurate extraction and application of seismic wave parameters, which may cause deviations in experimental results. However, this solution makes the matching process more intuitive and efficient through modular design, and improves the accuracy of the simulation through real-time comparison.
[0041] The use of the comparison module in the technical solution can quickly determine the corresponding maximum and minimum acceleration values after screening out the transverse and longitudinal wave data that meet the error threshold, and output these values to the earthquake experiment simulation device. This design allows the movable range of the acceleration to be clearly defined by the maximum and minimum acceleration values, while the existing technology in this regard usually only focuses on the monitoring of displacement or velocity, lacks in-depth analysis of acceleration characteristics, and leads to insufficient dynamic response evaluation during the experiment. By directly linking the acceleration range setting with the displacement parameters, this solution can more accurately reflect the impact of seismic waves on the structure and improve the reliability of the system.
[0042] The mechanism by which the processor continuously adjusts the transverse and longitudinal wave data of the seismic wave parameter model whose error value is within a certain threshold reflects the dynamic adjustment capability of this solution. By adjusting the movable range of the displacement parameter generated by the reciprocating motion until it is consistent with the maximum and minimum acceleration values, the flexibility and adaptability of the experimental process are enhanced. This adaptive adjustment mechanism is relatively rare in the prior art. Many experimental equipment often rely on manual adjustment or fixed parameters, which makes it difficult to achieve real-time response and precise control, resulting in increased complexity and uncertainty in the experiment. In contrast, this solution can ensure that the experimental conditions are always kept in the best state through real-time monitoring and automatic adjustment, thereby improving the accuracy and reliability of the experiment.
[0043] The shear wave data and longitudinal wave data of the adjusted seismic wave parameter model are used as a seismic wave simulation database, the number of seismic wave parameter models in the seismic wave simulation database is set, and the number of seismic wave waveforms for the seismic isolation device test is set, and a seismic wave simulation database is established in the test equipment; the accelerations of the maximum acceleration and the minimum acceleration in the seismic wave parameter model are respectively selected from the seismic wave simulation database, and the selected accelerations are input into the seismic isolation device for test setting; the seismic isolation device is placed on the earthquake experiment simulation device for test, and the test time is recorded, and the shear wave data and longitudinal wave data of the seismic wave parameter model in the seismic wave simulation database are marked with acceleration, velocity, and displacement, and data mark numbers are set, and the data mark numbers are recorded.
[0044] The main difference between the above technical solution and the prior art is that it innovatively introduces a seismic wave simulation database, and uses the seismic wave parameter model in the database to perform test settings and data recording for the seismic isolation device. In the prior art, the test of the seismic isolation device usually relies on actual earthquake records or standard earthquake waveforms. Although these methods can provide certain test data, they often lack flexibility and diversity. In contrast, the present technical solution can generate and store a variety of seismic wave parameter models by establishing a seismic wave simulation database, thereby providing richer and more diverse seismic waveforms for the test of the seismic isolation device.
[0045] Specifically, this technical solution first sets the number of seismic wave parameter models in the seismic wave simulation database. This setting is directly related to the number of seismic wave waveforms used in the seismic isolation device test, which increases the flexibility and controllability of the test. Then, the maximum and minimum accelerations are selected from the seismic wave simulation database, and these accelerations are input into the seismic isolation device for test setting. This method can not only cover a wider range of earthquake intensities, but also more comprehensively evaluate the performance of the seismic isolation device under different earthquake conditions.
[0046] During the test, the seismic isolation device was placed on the earthquake experiment simulation device, the test time was recorded, and the transverse wave data and longitudinal wave data of the seismic wave parameter model in the seismic wave simulation database were marked with acceleration, velocity, and displacement as data and set with data mark serial numbers. This step ensures the systematicness and traceability of the test data. In this way, the technical solution not only improves the accuracy and reliability of the test data, but also provides a solid foundation for subsequent data analysis and device optimization.
[0047] The test parameters of the seismic isolation device are recorded, and a time monitoring cycle is set. By monitoring the maximum displacement and minimum displacement of the test of the seismic isolation device, the maximum displacement and minimum displacement of the test of the seismic isolation device are respectively matched with the time in the data tag and stored in the processor, a displacement change control curve is set, and the time is divided into several time periods according to the time monitoring cycle. The maximum acceleration and minimum acceleration of the seismic isolation device in several time periods are plotted on the displacement change control curve, and the displacement change control curve of the test of the seismic isolation device is saved; a detection cycle is set, and the seismic isolation device is tested a set number of times, and the maximum acceleration and minimum acceleration of the seismic isolation device in the detection time period of the set cycle are recorded, and the maximum acceleration and minimum acceleration of the seismic isolation device in the detection time period of the set cycle are selected for calculation, and the average acceleration and maximum displacement in the detection time period are calculated, and they are plotted as a displacement and force value change test curve; the energy dissipation parameters of the seismic isolation device of the seismic isolation device are calculated, and the displacement change control curve and the displacement and force value change test curve are output to the display terminal for display, and the shock absorption effect of the seismic isolation device of the seismic isolation device is obtained according to the energy dissipation parameters.
[0048] The main difference between the above technical solution and the prior art lies in its systematic and refined test parameter recording, data analysis and result display methods. In the prior art, the test parameter recording of the seismic isolation device is often relatively simple, lacking systematic data management and analysis methods, resulting in insufficient accuracy and reliability of the test results. In contrast, the present technical solution sets a time monitoring cycle, records in detail the maximum and minimum displacement values of the seismic isolation device test, and stores these data in correspondence with time, thereby ensuring the integrity and traceability of the test data.
[0049] This technical solution first sets a time monitoring cycle, monitors the test displacement of the seismic isolation device, records the maximum and minimum values of the displacement, and stores these data in the processor in correspondence with time. This detailed data recording method not only improves the accuracy of the data, but also provides a solid foundation for subsequent data analysis. Next, this technical solution sets a displacement change control curve chart, divides the time into several time periods according to the time monitoring cycle, and plots the maximum and minimum acceleration values of the seismic isolation device in each time period on the displacement change control curve chart. This graphical data display method makes the test results more intuitive and easy to understand.
[0050] This technical solution also sets a detection cycle, conducts multiple tests on the seismic isolation device, records the maximum and minimum acceleration values of the seismic isolation device within the detection period of the set cycle, calculates the average acceleration and maximum displacement within the detection period, and plots them as a displacement and force value change test curve. This method of multiple tests and data analysis can more comprehensively evaluate the performance of the seismic isolation device and improve the reliability of the test results.
[0051] This technical solution calculates the energy dissipation parameters of the seismic isolation device, and outputs the displacement change control curve and the displacement and force value change test curve to the display terminal for display, and obtains the shock absorption effect of the seismic isolation device according to the energy dissipation parameters. This comprehensive data analysis and result display method not only improves the scientificity and rationality of the test results, but also provides strong data support for the optimization design of the seismic isolation device.
[0052] The y-axis of the displacement and force value change test curve graph is displacement acceleration, and the x-axis of the displacement and force value change test curve graph is time. The displacement acceleration on the displacement and force value change test curve graph respectively includes the maximum displacement acceleration and the minimum displacement acceleration of the seismic isolation device test. The parameter data set on the displacement and force value change test curve graph corresponds to the test time of the seismic isolation device test. The ratio of the displacement acceleration on the displacement change control curve graph to the displacement change on the displacement and force value change test curve graph during the test of the seismic isolation device is calculated according to the test time of the seismic isolation device test, and the ratio is used as the energy dissipation parameter of the seismic isolation device. The seismic isolation effect of the seismic isolation device is obtained according to the energy dissipation parameter.
[0053] This application document innovatively introduces a displacement and force value change test curve chart, and calculates the energy dissipation parameters of the seismic isolation device through the parameter data on the curve chart, thereby evaluating the shock absorption effect of the seismic isolation device. In the prior art, the test results of the seismic isolation device usually only rely on simple data recording and analysis, lacking a systematic and scientific evaluation method. In contrast, the present technical solution realizes a refined analysis and evaluation of the test process of the seismic isolation device through the displacement and force value change test curve chart.
[0054] Specifically, the technical solution first sets the y-axis of the displacement and force value change test curve graph as displacement acceleration and the x-axis as time, and marks the maximum displacement acceleration and minimum displacement acceleration of the seismic isolation device test on the curve graph. This graphical data display method not only makes the test results more intuitive, but also provides convenience for subsequent data analysis. Next, the technical solution matches the parameter data on the displacement and force value change test curve graph with the test time of the seismic isolation device test, and calculates the ratio of the displacement acceleration on the displacement change control curve graph to the displacement change on the displacement and force value change test curve graph to obtain the energy dissipation parameters of the seismic isolation device. This parameter calculation method based on the curve graph can more accurately evaluate the performance of the seismic isolation device during the test.
[0055] This technical solution evaluates the shock absorption effect of the seismic isolation device based on the energy dissipation parameter. As an important indicator for measuring the performance of the seismic isolation device, the energy dissipation parameter can fully reflect the shock absorption capacity of the device under different test conditions. Through this scientific evaluation method, this technical solution not only improves the accuracy and reliability of the test results, but also provides strong data support for the optimization design of the seismic isolation device.
