Description

Technical Field

[0001] This invention relates to the field of bridge wind resistance technology, specifically to a self-powered cable-stayed bridge vortex vibration control device and method. Background Technology

[0002] Cable-stayed bridges are a common structural form for long-span bridges, and the stay cables are a crucial component. As modern bridge structures evolve towards longer spans, greater flexibility, and lower damping, stay cables are becoming increasingly longer. Their characteristics of small mass, high flexibility, and low self-damping have made vortex-induced resonance (VCR) in the main girder section a key focus of wind resistance research. VCR, or vortex-induced vibration, is a self-limiting wind-induced vibration phenomenon with both forced and self-excited characteristics. It is caused by vortices that fall regularly at fixed time intervals as airflow passes over the structural surface. While VCR does not directly cause dynamic instability or failure of the bridge, large-amplitude VCR can significantly compromise the bridge's structural safety and driving comfort, affecting its normal use. The structural characteristics of cable-stayed bridges make them prone to high-order vortex-induced vibrations under wind excitation, which can affect structural fatigue and cause psychological distress to vehicles and pedestrians on the bridge. Therefore, research on suppression measures for high-order vortex-induced vibrations in stay cables is both necessary and significant.

[0003] Therefore, a self-powered cable vortex vibration control device and method that can effectively suppress high-order vortex-induced vibration of cable-stayed cables are provided, and a self-powered cable vortex vibration control system and its arrangement method are further provided. Summary of the Invention

[0004] To address the aforementioned problems in the prior art, this invention provides a self-powered cable vortex vibration control device and method that can effectively suppress higher-order vortex-induced vibrations of cable-stayed bridges, and further provides a self-powered cable vortex vibration control system and its arrangement method.

[0005] First, this invention provides a self-powered cable-stayed bridge vortex vibration control device, comprising a vortex suppression system and a power supply system.

[0006] The vortex suppression system includes:

[0007] The monitoring device monitors environmental information, including wind speed and wind direction, and state information, including displacement and acceleration, for the bridge's cable stays.

[0008] The control device, based on the monitoring information from the monitoring device, determines the order of vortex-induced vibration of the bridge's stay cables through finite element modeling and control algorithms; and

[0009] The synthetic jet device determines the working parameters of the synthetic jet based on the order of vortex-induced vibration and the incoming wind speed and direction, and starts working to disrupt the flow field structure of the bridge cable stays and thus suppress vortex-induced vibration; the working parameters include the number of participants, jet angle, jet direction, and jet intensity.

[0010] The energy supply system includes:

[0011] Power generation devices, including blades, and triboelectric nanogenerators that generate electricity using ambient wind energy and the action of the blades; and

[0012] An energy storage and power supply device that stores electrical energy and provides power to the various devices of the vortex suppression system;

[0013] It also includes a housing, and the synthetic jet device is disposed inside the cavity of the housing, and the external flow field structure of the cable stay is disturbed through the jet holes on the housing.

[0014] The housing includes two interlocking semi-cylindrical structures. The semi-cylindrical structures have multiple independent semi-circular cavities, semi-circular connecting holes for connecting lines to the power supply system to pass through, semi-circular through holes for stay cables to pass through, and fixing ends for fixing bolts to pass through and fix.

[0015] The synthetic jet device includes multiple exciters installed in the intermediate cavity of the housing and jet holes formed on the housing corresponding to the exciters. The internal flow field of the synthetic jet device is connected to the external flow field of the cable through the jet holes, and the jet direction forms an angle with the cylindrical tangent direction at the location of the jet hole, with the angle ranging from 45° to 135°.

[0016] The synthetic jet device includes four exciters arranged symmetrically along the cross section of the cable-stayed bridge in the intermediate cavity. Each exciter works independently or in combination according to the vortex-induced vibration order and the incoming wind speed and direction, thereby disrupting the flow field structure of the cable-stayed bridge and suppressing vortex-induced vibration.

[0017] A hollow cavity is provided between the end cavity of the housing and the fixed end. The energy storage and power supply device is located in the end cavity, and the power generation device is located in the hollow cavity.

[0018] The monitoring device includes a wind speed sensor for monitoring wind direction and wind speed, and an acceleration sensor for monitoring displacement and acceleration.

[0019] The control device includes a preloaded finite element model and an intelligent control algorithm model. The monitoring device calculates and determines the vortex-induced vibration order of the bridge based on the wind direction, wind speed, displacement and / or acceleration data it monitors.

[0020] Secondly, the present invention also provides a self-powered cable-stayed bridge vortex vibration control method, which includes the following steps:

[0021] S1. Monitor environmental information, including wind speed and wind direction, at the cable-stayed bridge location, as well as state information, including acceleration and displacement, of the cable-stayed bridge using monitoring devices;

[0022] S2. Based on the monitoring information from the monitoring device, the control device analyzes and determines the order of vortex-induced vibration of the bridge cable stays through finite element model and control algorithm; if the control device determines that the real-time wind speed exceeds the critical wind speed of vortex-induced vibration, then execute S3; if the control device determines that the real-time wind speed does not exceed the critical wind speed of vortex-induced vibration, then return to S1.

[0023] S3. The synthetic jet device determines the synthetic jet operating parameters and starts operation based on the vortex-induced vibration order and incoming wind speed and direction determined in S2; among which, the operating parameters include the number of participants, jet angle, jet direction, and jet intensity;

[0024] S4. The monitoring device continues to monitor, and the control device continues to analyze and determine the order of vortex-induced vibration of the bridge cable stays through finite element model and control algorithm. If the control device determines that the real-time wind speed still exceeds the critical wind speed of vortex-induced vibration, the synthetic jet device jumps to execute S3. If the control device determines that the real-time wind speed does not exceed the critical wind speed of vortex-induced vibration, the synthetic jet device ends its work.

[0025] Furthermore, the present invention provides a self-powered cable-stayed bridge vortex vibration control system, which includes multiple self-powered cable-stayed bridge vortex vibration control devices as described above. The self-powered cable-stayed bridge vortex vibration control devices are distributed along the cable-stayed bridge and are synchronously controlled through synchronous wireless data.

[0026] Finally, the present invention provides a method for arranging the self-powered cable-stayed bridge vortex vibration control system as described above, which includes the following steps:

[0027] (1) Perform three-dimensional vortex-induced vibration simulation on the cable-stayed bridge;

[0028] (2) Determine the vortex-induced vibration dense region and vortex-induced vibration sparse region based on the results of the three-dimensional vortex-induced vibration simulation data;

[0029] Two or more of the self-powered cable-stayed bridge vortex vibration control devices are arranged in the vortex vibration-dense area, and one or two of the self-powered cable-stayed bridge vortex vibration control devices are arranged in the vortex vibration-sparse area.

[0030] The technical solution of this invention has the following advantages:

[0031] In this invention, firstly, the ambient wind energy is converted into electrical energy and stored for use through a combination of blades and nano-friction materials, achieving autonomous functionality and solving the problem of power supply difficulties for vortex-induced vibration control devices in the prior art; secondly, based on data such as wind speed and direction, cable acceleration and displacement from the monitoring device, parameters such as the number of jets, jet intensity, and jet angle are adjusted and controlled in real time by the control device, thereby achieving effective control of cable vortex-induced vibration; thirdly, this autonomously powered cable vortex-induced vibration control device integrates monitoring, control, excitation (synthetic jet device), and power supply, and its structure is compact and lightweight, which can be flexibly distributed and arranged along the cable as needed, thereby better suppressing high-order vortex-induced vibration of the cable.

Detailed Implementation

[0042] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The following content is merely illustrative and explanatory of the concept of the present invention. Those skilled in the art can make various modifications or additions to the described specific embodiments or use similar methods to replace them, as long as they do not depart from the inventive concept or exceed the scope defined by the claims, all of which should fall within the protection scope of the present invention. Unless otherwise specified, the experimental reagents and materials used in the following embodiments are commercially available.

[0043] Example 1: As Figure 1 and 2 As shown, this embodiment provides a self-powered cable-stayed bridge vortex vibration control device 1, including a vortex suppression system and a power supply system.

[0044] The vortex suppression system includes:

[0045] The monitoring device monitors environmental information, including wind speed and wind direction, and state information, including displacement and acceleration, of the bridge cable-stayed cable 11.

[0046] Control device 10, based on the monitoring information from the monitoring device, determines the vortex-induced vibration order of the bridge stay cable 11 through finite element model and control algorithm analysis; and

[0047] The synthetic jet device 9 determines the working parameters of the synthetic jet based on the vortex-induced vibration order and the incoming wind speed and direction, and starts working to disrupt the flow field structure of the bridge cable-stayed cable 11 and thus suppress vortex-induced vibration; the working parameters include the number of jets participating in the synthetic jet device 9, the jet angle, the jet direction, and the jet intensity.

[0048] The energy supply system includes:

[0049] The power generation device includes blades 15 and a triboelectric nanogenerator 12 that generates electricity under the influence of ambient wind energy and the blades 15; and

[0050] Energy storage and power supply device 8 stores electrical energy and provides electrical energy to each device of the vortex suppression system;

[0051] It also includes a housing 0, the synthetic jet device 9 is disposed in the cavity of the housing 0, and the external flow field structure of the cable 11 is disturbed through the jet hole 13 on the housing 0.

[0052] The monitoring device includes a wind speed sensor 3 for monitoring wind direction and wind speed, and an acceleration sensor 2 for monitoring displacement and acceleration; the control device 10 includes a pre-loaded finite element model and an intelligent control algorithm model, and the wind direction, wind speed, displacement and / or acceleration data monitored by the monitoring device are used to calculate and determine the vortex-induced vibration order of the bridge; the energy storage and power supply device 8 includes a graphene battery.

[0053] In this embodiment, the power generation device preferably employs triboelectric nanogenerator (TENG) technology. Under wind-driven conditions, the blades 15 and the nano-friction material combine to generate electricity, which is then stored in graphene batteries to power the monitoring device, control device 10, synthetic jet device 9, and LED landscape lights 17 on the bridge or cable-stayed bridge 11. This power generation device utilizes the advantages of a disordered pendulum's low operating frequency and high electromechanical conversion efficiency in its physical design, while also providing an innovative and effective method for collecting green energy and offering a new direction for bridge wind resistance.

[0054] Furthermore, such as Figure 3 and 4 As shown, the housing 0 includes two interlocking semi-cylindrical structures. Each semi-cylindrical structure has multiple independent semi-circular cavities, a semi-circular connecting hole for the connecting wire to the power supply system, a semi-circular through hole for the stay cable 11 to pass through, and a fixing end for the fixing bolt 18 to pass through and fix. In this embodiment, the two semi-cylindrical structures interlock and fix together to form three independent cavities: an intermediate cavity 19 and two end cavities 20. The synthetic jet device 9 is installed in the intermediate cavity 19, and the graphene battery is installed in the end cavities 20.

[0055] The synthetic jet device 9 includes a plurality of exciters 16 installed in the intermediate cavity 19 of the housing 0 and jet holes 13 formed on the housing 0 corresponding to the exciters 16. The internal flow field of the synthetic jet device 9 is connected to the external flow field of the cable 11 through the jet holes 13, and the jet direction forms an angle with the cylindrical tangent direction at the location of the jet hole 13, with the angle ranging from 45° to 135°.

[0056] In a preferred embodiment, the synthetic jet device 9 includes four exciters 16 arranged symmetrically along the cross section of the cable 11 in the intermediate cavity 19. Each exciter 16 works independently or in combination according to the vortex-induced vibration order and the incoming wind speed and direction, thereby disrupting the flow field structure of the cable 11 of the bridge and suppressing vortex-induced vibration.

[0057] A hollow cavity 21 is provided between the end cavity and the fixed end of the housing 0. The energy storage and power supply device 8 is located in the end cavity 20, and the power generation device is located in the hollow cavity 21. An air inlet 14 is formed on the hollow cavity 21, and ambient wind energy enters the hollow cavity 21 through the air inlet 14 to drive the blades 15 to rotate. At the same time, the wind speed sensor 3 is also installed in the hollow cavity 21; the acceleration sensor 2 is directly fixed to the inclined cable 11 outside the housing 0.

[0058] In the first aspect, this embodiment converts ambient wind energy into electrical energy and stores it for use through a combination of blades 15 and nano-friction materials, achieving autonomous functionality and solving the problem of power supply difficulties for vortex-induced vibration control devices in the prior art. In the second aspect, based on data such as wind speed and direction, acceleration and displacement of the cable 11, the control device 10 adjusts and controls parameters such as the number of jets, jet intensity, and jet angle in real time, thereby achieving effective control of cable vortex-induced vibration. In the third aspect, this autonomously powered cable vortex-induced vibration control device 1 integrates monitoring, control, excitation (synthetic jet device 9), and power supply. Its structure is compact and lightweight, and it can be flexibly distributed along the cable 11 as needed, thereby better suppressing high-order vortex-induced vibration of the cable.

[0059] like Figure 5 The figure shows a comparison of the mid-span vortex-induced vibration response of a stay cable equipped with the self-powered cable vortex-induced vibration control device 1 described in this embodiment and a stay cable without vortex-induced vibration control. The comparison shows that the synthetic jet device 9 provided in this application can significantly reduce the vortex-induced vibration response amplitude and effectively control the vortex-induced vibration of the stay cable 11.

[0060] Example 2: As Figure 6 As shown, based on Embodiment 1, this embodiment provides a corresponding self-powered cable-stayed bridge vortex vibration control method, which includes the following steps:

[0061] S1. Monitor environmental information including wind speed and wind direction at the cable-stayed cable 11, as well as state information including acceleration and displacement of the cable-stayed cable 11, through the monitoring device;

[0062] S2. Based on the monitoring information from the monitoring device, the control device 10 determines the vortex-induced vibration order of the bridge cable-stayed cable 11 through finite element model and control algorithm analysis; if the control device 10 determines that the real-time wind speed exceeds the critical wind speed of vortex-induced vibration, then execute S3; if the control device 10 determines that the real-time wind speed does not exceed the critical wind speed of vortex-induced vibration, then return to S1.

[0063] S3. The synthetic jet device 9 determines the synthetic jet operating parameters and starts operation based on the vortex-induced vibration order and incoming wind speed and direction determined in S2; among which, the operating parameters include the number of participants, jet angle, jet direction, and jet intensity;

[0064] S4. The monitoring device continues to monitor, and the control device 10 continues to analyze and determine the vortex-induced vibration order of the bridge cable 11 through the finite element model and control algorithm. If the control device 10 determines that the real-time wind speed still exceeds the critical wind speed of vortex-induced vibration, the synthetic jet device 9 jumps to execute S3. If the control device 10 determines that the real-time wind speed does not exceed the critical wind speed of vortex-induced vibration, the synthetic jet device 9 ends its work.

[0065] In conjunction with Embodiment 1, the specific control method of the self-powered cable-stayed bridge vortex vibration control device 1 is as follows:

[0066] First, the accelerometer 2 monitors the real-time acceleration of the cable 11, and the wind speed sensor 3 monitors the wind speed near the cable 11.

[0067] Then, the monitoring data is transmitted to the control device 10. The intelligent algorithm controls the finite element model and the control algorithm to determine whether the vortex-induced vibration order of the bridge cable 11 and the wind speed exceed the critical wind speed of vortex-induced vibration. If the control device 10 determines that the real-time wind speed does not exceed the critical wind speed of vortex-induced vibration, the synthetic jet device 9 will not start working.

[0068] If the control device 10 determines that the real-time wind speed exceeds the critical wind speed for vortex vibration, it then determines the number of participants, jet direction, jet intensity, and other operating parameters of the synthetic jet device 9 based on the determined higher-order vortex vibration order, and starts operation. The synthetic jet device 9 begins to vibrate periodically, and the fluid inside the cavity is driven to move. The fluid flows out or into the cavity through the jet hole 13, and forms a periodic blowing and suction process on the external flow field of the cable-stayed cable 11 near the jet hole 13. One blowing and suction cycle of the jet device constitutes one cycle, and the vibration phase of the synthetic jet at the symmetrical positions above and below and left and right is consistent in each cycle.

[0069] After the synthetic jet device 9 is turned on in synthetic jet working mode, it can enhance the symmetry of the separation point of the cable 11, enhance the flow symmetry, and make the loads perpendicular to the flow direction cancel each other out, thereby suppressing the vortex vibration of the cable 11.

[0070] Finally, if the stay cable 11 returns to normal working condition, that is, if the monitoring device continues to monitor it, the control device 10 continues to analyze and determine the vortex-induced vibration order of the bridge stay cable 11 through the finite element model and control algorithm. If the control device 10 determines that the real-time wind speed does not exceed the critical wind speed of vortex-induced vibration, the synthetic jet device 9 stops working. If the control device 10 determines that the real-time wind speed still exceeds the critical wind speed of vortex-induced vibration, the synthetic jet device 9 continues to work until the stay cable 11 returns to normal working condition.

[0071] Example 3: Based on Examples 1 and 2, this example further provides an autonomously powered cable-stayed bridge vortex vibration control system, which includes multiple autonomously powered cable-stayed bridge vortex vibration control devices 1 as described in Example 1. The autonomously powered cable-stayed bridge vortex vibration control devices 1 are distributed along the cable 11 and are synchronously controlled through synchronous wireless data.

[0072] In actual use, multiple self-powered cable vortex vibration control devices 1 can be installed on the cable 11 as needed. The number of devices can be adjusted according to the length of the cable 11 and the different environmental wind energy of different cables 11. The multiple self-powered cable vortex vibration control devices 1 can achieve synchronous control by transmitting data wirelessly.

[0073] Example 4: Based on Example 3, this example provides a method for arranging a self-powered cable-stayed bridge vortex vibration control system, which includes the following steps:

[0074] (1) Perform three-dimensional vortex-induced vibration simulation on cable 11;

[0075] (2) Determine the vortex-induced vibration dense region and vortex-induced vibration sparse region based on the results of the three-dimensional vortex-induced vibration simulation data;

[0076] (3) Two or more of the self-powered cable-stayed bridge vortex vibration control devices 1 are arranged in the vortex-vibration-dense area, and one or two of the self-powered cable-stayed bridge vortex vibration control devices 1 are arranged in the vortex-vibration-sparse area, such as... Figure 7 As shown.

[0077] For the same cable 11, the intensity of vortex-induced vibration at different locations can be determined by three-dimensional vortex-induced vibration simulation, thereby forming a relatively dense and sparse vortex-induced vibration region. A relatively self-powered cable vortex-induced vibration control device 1 can be arranged in the dense vortex-induced vibration region to achieve the most effective and appropriate vortex-induced vibration control and adjustment of the cable 11.

[0078] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
