Description

Technical Field

[0002] In the field of structural wind engineering, wind turbine towers (circular columns) are prone to vortex-induced vibration under wind loads, which can seriously affect the structural safety of the tower. Although vortex-induced vibration does not directly cause structural dynamic instability and failure, large-amplitude vortex-induced vibration can reduce assembly accuracy during construction, increase construction difficulty, endanger the safety of construction personnel, affect the structural safety during operation, reduce fatigue life, and ultimately affect the normal use of the structure. Therefore, this application proposes a vortex-induced vibration suppression method based on circular column structures to suppress the occurrence of vortex-induced vibration or reduce its impact, thereby improving the structural safety. Summary of the Invention

[0005] According to one aspect of the embodiments of this application, a vortex-induced vibration suppression method based on a circular cylindrical structure is provided, applied to a vortex-induced vibration suppression system, wherein the vortex-induced vibration suppression system can rotate around the circular cylindrical structure under the action of a target incoming wind, and the method includes:

[0006] The wind-induced torque parameters of the vortex-induced vibration suppression system under the action of the target incoming wind are obtained, and the wind-induced torque parameters are used to make the vortex-induced vibration suppression system rotate around the circular cylindrical structure.

[0007] Obtain the frictional torque parameters experienced by the vortex-induced vibration suppression system when it rotates around the circular cylindrical structure;

[0008] Determine whether the wind-induced torque parameter is greater than the friction torque parameter. If not, adjust the aerodynamic design parameters of the vortex vibration suppression system until the wind-induced torque parameter is greater than the friction torque parameter.

[0009] If the wind-induced torque parameter is greater than the friction torque parameter, determine whether the wind angle of attack formed by the direction of the vortex vibration suppression system and the direction of the target incoming wind at the wake of the target incoming wind is less than the preset wind angle of attack. If not, adjust the aerodynamic design parameters of the vortex vibration suppression system until the wind angle of attack is less than the preset wind angle of attack.

[0010] When the wind angle of attack is less than the preset wind angle of attack, the first vortex-induced vibration parameter of the circular cylindrical structure after the vortex-induced vibration suppression system is applied and the second vortex-induced vibration parameter of the circular cylindrical structure when the vortex-induced vibration suppression system is not applied are obtained.

[0011] If the first vortex vibration parameter is greater than or equal to the second vortex vibration parameter, then the aerodynamic design parameters of the vortex vibration suppression system are adjusted until the first vortex vibration parameter is less than the second vortex vibration parameter.

[0012] In one embodiment of this application, based on the aforementioned scheme, the vortex-induced vibration suppression system includes a partition plate device, a pulley device, and an annular track device surrounding the circular cylindrical structure. The pulley device slides within the annular track device and is connected to the partition plate device. Under the action of the target incoming airflow, the pulley device drives the partition plate device to rotate around the circular cylindrical structure. The aerodynamic design parameters include the number of partition plates in the partition plate device, the included angle between each partition plate, the overall size parameters of each partition plate, the opening parameters of each partition plate, and the number of pulleys in the pulley device.

[0013] In one embodiment of this application, based on the foregoing scheme, the partition plate device includes a first partition plate and a second partition plate, and the step of obtaining the wind-induced torque parameters of the vortex-induced vibration suppression system under the action of the target incoming wind includes:

[0015] Obtain the drag torque generated by the second partition plate under the action of the target incoming airflow;

[0016] The wind-induced torque parameters are determined based on the driving torque and the resisting torque.

[0017] In one embodiment of this application, based on the foregoing scheme, obtaining the driving torque generated by the first partition plate under the action of the target incoming airflow includes:

[0018] The following parameters are obtained: the incoming wind speed of the target incoming wind, the characteristic diameter of the vortex-induced vibration suppression system, the air density of the environment in which the circular cylindrical structure is located, the first length of the first partition plate, and the drag coefficient of the vortex-induced vibration suppression system under the action of the target incoming wind.

[0019] The thrust experienced by the first partition plate under the action of the target incoming wind is determined based on the incoming wind speed, the characteristic diameter, the air density, the first length, and the drag coefficient.

[0020] The diameter of the circular cylindrical structure, the first distance between the first partition plate and the outer surface of the circular cylindrical structure, and the dynamic angle of attack formed by the direction of the target incoming wind and the central axis of the vortex vibration suppression system are obtained.

[0021] The thrust, diameter, first distance, first length, and dynamic wind angle of attack are input into a preset first calculation formula to obtain the thrust torque;

[0022] The preset first calculation formula is as follows:

[0023]

[0024] In the formula, For the thrust, For the diameter, The first length of the first partition plate. The dynamic wind angle of attack, For the first distance, The driving torque is described above.

[0025] In one embodiment of this application, based on the foregoing scheme, obtaining the drag torque generated by the second partition plate under the action of the target incoming airflow includes:

[0026] The second length of the second partition plate and the second distance between the second partition plate and the outer surface of the circular column structure are obtained, and the resistance of the second partition plate under the action of the target incoming wind is determined according to the incoming wind speed, the characteristic diameter, the air density, the second length and the drag coefficient.

[0027] The drag force torque is obtained by inputting the drag, the diameter, the second distance, the second length, and the dynamic wind attack angle into a preset second calculation formula.

[0028] The preset second calculation formula is as follows:

[0029]

[0030] In the formula, For the resistance, For the diameter, The second length of the second partition plate. The dynamic wind angle of attack, The second distance, The drag torque is the stated drag force.

[0031] In one embodiment of this application, based on the foregoing scheme, the wind-induced torque parameter is obtained by the following formula:

[0032] In the formula, The wind-induced torque parameter, The driving torque, The drag torque is the stated drag force.

[0033] In one embodiment of this application, based on the foregoing scheme, obtaining the frictional torque parameters experienced by the vortex-induced vibration suppression system when rotating around the circular cylindrical structure includes:

[0034] The material density of the partition plate device, the number of partition plates, the overall size parameters of the partition plates, the mass parameters of the pulley device, the dynamic friction coefficient of the pulley device, the diameter of the circular cylindrical structure, and the distance between the partition plate device and the outer surface of the circular cylindrical structure are obtained.

[0035] The material density, quantity, overall size parameters, mass parameters, dynamic friction coefficient, distance, diameter, and gravitational acceleration are input into a preset third calculation formula to obtain the friction torque parameters.

[0036] The preset third calculation formula is as follows:

[0037]

[0038] In the formula, The number of the partitions. The overall size parameters are as follows. The density of the material is... The quality parameter is... It is the acceleration due to gravity. The coefficient of dynamic friction is... For the diameter, The distance between the partition plate device and the outer surface of the circular column structure is [missing information]. The friction torque parameter is... This represents frictional resistance.

[0039] In one embodiment of this application, based on the foregoing scheme, adjusting the aerodynamic design parameters of the vortex-induced vibration suppression system includes:

[0040] Choose one or more of the following five adjustment methods as the target adjustment method: adjust the number of the partitions, adjust the included angle between the partitions, adjust the overall size parameters of the partitions, adjust the opening parameters of the partitions, and adjust the number of pulleys.

[0041] The aerodynamic design parameters of the vortex vibration suppression system are adjusted according to the target adjustment method.

[0042] According to one aspect of the embodiments of this application, a computer-readable storage medium is provided that stores a computer program thereon, the computer program including executable instructions that, when executed by a processor, implement the method described in the above embodiments.

[0043] According to one aspect of the embodiments of this application, an electronic device is provided, including: one or more processors; and a memory for storing executable instructions of the processors, which, when executed by the one or more processors, cause the one or more processors to perform the method as described in the above embodiments.

[0044] The beneficial effects of this application are: This application applies a vortex-induced vibration suppression system to the outer surface of a cylindrical structure, which can rotate around the cylindrical structure under the influence of the target incoming airflow. By designing or adjusting the aerodynamic parameters of the vortex-induced vibration suppression system, the vortex-induced vibration effect of the cylindrical structure caused by the target incoming airflow can be reduced, thereby improving the safety of the cylindrical structure.

[0045] Furthermore, if the wind-induced torque parameter is greater than the friction torque parameter, it is determined whether the wind attack angle formed by the direction of the vortex-induced vibration suppression system and the direction of the target incoming wind at the wake of the target incoming wind is less than the preset wind attack angle. If the wind attack angle is greater than or equal to the preset wind attack angle, it indicates that the aerodynamic design parameters do not meet the requirements of the wind attack angle and cannot effectively reduce the vortex-induced vibration effect caused by the target incoming wind. At this time, the aerodynamic design parameters can be adjusted to make the wind attack angle less than the preset wind attack angle to meet the requirements of the wind attack angle.

[0046] Furthermore, merely meeting the wind angle of attack requirement is insufficient to reduce the vortex-induced vibration effect. Therefore, based on meeting the wind angle of attack requirement, it is necessary to obtain the first vortex-induced vibration parameter experienced by the cylindrical structure after applying the vortex-induced vibration suppression system, and compare it with the second vortex-induced vibration parameter experienced by the cylindrical structure without applying the vortex-induced vibration suppression system. This will determine whether the vortex-induced vibration suppression system applied in this application can effectively reduce the vortex-induced vibration effect. If it does not reduce it, then the aerodynamic design parameters of the vortex-induced vibration suppression system should be readjusted until the first vortex-induced vibration parameter experienced after applying the vortex-induced vibration suppression system is significantly lower than the second vortex-induced vibration parameter experienced without applying the vortex-induced vibration suppression system, thereby reducing the vortex-induced vibration effect caused by the target incoming wind, or directly suppressing the occurrence of the vortex-induced vibration effect.

[0047] Therefore, this application verifies the aerodynamic design parameters and continuously adjusts them when the set requirements are not met, so that the vortex vibration suppression system can rotate to the wake of the target incoming wind under the action of the target incoming wind, which can effectively reduce the vortex vibration effect of the circular cylindrical structure or directly suppress the occurrence of the vortex vibration effect.

[0072] The following is a detailed description of the vortex-induced vibration suppression system proposed in the embodiments of this application:

[0073] like Figure 1 As shown, Figure 1 This is a perspective view of a vortex-induced vibration suppression system installed on the outer surface of a circular column (tower) structure, according to an embodiment of this application. The vortex-induced vibration suppression system includes a partition plate device, a pulley device, and a ring track device surrounding the circular column structure. Specifically, the partition plate device in this embodiment may include two partition plates.

The number of partition plates is not limited here.

[0076] The following provides an exemplary description of the installation method of the vortex-induced vibration suppression system and the specific dimensional parameters of each component (i.e., the aerodynamic design parameters described in the embodiments of this application):

[0077] Specifically, the upper annular track 110 and the lower annular track 111 are respectively installed on the upper and lower sides of the outer surface of the tower structure (circular column structure), with a distance of 6000mm between the upper and lower sides. The outer diameter of the annular track device is 3400mm, the inner diameter is 3000mm, the edge height of the annular track device is 80mm, and the edge thickness is 10mm.

[0078] Furthermore, two upper pulley sets 120 are installed on the upper circular track 110, and each of the upper pulley set 120 and the lower pulley set 140 is equipped with a vertical main pulley 121 and a horizontal auxiliary pulley 122.

[0079] Furthermore, bolted connecting plates 151 are connected to the back of the two upper pulley groups 120, the two lower pulley groups 140, the two central connecting blocks 130, and each perforated plate partition 210. The bolted connecting plates 151 are connected to the perforated plate partition 210 by bolts.

[0080] Furthermore, the two upper pulley sets 120, the two lower pulley sets 140, the two middle connecting blocks 130, and the bolt connecting plates 151 on their backs are connected on the inside by three cross diaphragms 150.

[0081] The upper pulley assembly 120 of this application is a rectangular shell structure equipped with pulleys. Its upper surface has a length of 510mm and a width of 300mm, its lower surface has a length of 445mm and a width of 300mm, its overall height is 310mm, and its thickness is 10mm; the vertical main pulley 121 has a diameter of 150mm.

[0082] The pulley assembly 140 is a rectangular shell structure equipped with pulleys. Its upper surface is 510mm long and 300mm wide, its lower surface is 460mm long and 300mm wide, its overall height is 310mm, and its thickness is 10mm.

[0084] It should be noted that the above description of the installation method of the vortex vibration suppression system and the specific values ​​of the dimensions of each component are merely illustrative examples. In other embodiments, the installation method may be changed, and the number of each component and the specific parameters of each component may also be adjusted. In other words, the aerodynamic design parameters described in the embodiments of this application can be arbitrarily adjusted as needed, and are not limited here.

[0085] The implementation details of the technical solutions in the embodiments of this application are described in detail below:

[0086] According to one aspect of the embodiments of this application, a vortex-induced vibration suppression method based on a circular cylindrical structure is provided, which is applied to a vortex-induced vibration suppression system that can rotate around the circular cylindrical structure under the action of the target incoming airflow. Figure 8 The flowchart below illustrates a vortex-induced vibration suppression method based on a circular cylindrical structure according to an embodiment of this application. The method includes at least steps S1 to S6, which are described in detail below:

[0087] In step S1, the wind-induced torque parameter of the vortex vibration suppression system under the action of the target incoming wind is obtained. The wind-induced torque parameter is used to make the vortex vibration suppression system rotate around the circular cylindrical structure.

[0088] Specifically, the target incoming wind speed can be set as needed. In the vortex-induced vibration suppression method based on a circular cylindrical structure proposed in this application, the incoming wind speed of the target wind can be set to the minimum vortex-induced vibration speed. The minimum vortex-induced vibration speed is used to characterize the minimum wind speed at which the circular cylindrical structure can experience vortex-induced vibration. That is, the vortex-induced vibration effect can occur at this minimum vortex-induced vibration speed. If the incoming wind speed of the target wind is lower than the minimum vortex-induced vibration speed, then the target wind cannot cause the circular cylindrical structure to experience vortex-induced vibration. Of course, the incoming wind speed of the target wind can also be set to other wind speed values, not limited to the minimum wind speed at which the circular cylindrical structure can experience vortex-induced vibration. It can also be higher than the minimum vortex-induced vibration speed. Therefore, in this embodiment, the incoming wind speed of the target wind is first set to the minimum vortex-induced vibration speed to explore various possible situations for the circular cylindrical structure and the vortex-induced vibration suppression system at this minimum vortex-induced vibration speed.

[0089] In one embodiment of this application, the vortex-induced vibration suppression system includes a partition plate device, a pulley device, and an annular track device surrounding the circular cylindrical structure. The pulley device slides within the annular track device and is connected to the partition plate device. Under the action of the target incoming airflow, the pulley device drives the partition plate device to rotate around the circular cylindrical structure. The aerodynamic design parameters include the number of partition plates in the partition plate device, the included angle between each partition plate, the overall size parameters of each partition plate, the opening parameters of each partition plate, and the number of pulleys in the pulley device.

[0090] Specifically, the specific component composition, installation method, and dimensional parameters of each component of the vortex-induced vibration suppression system of this application can all be collectively referred to as aerodynamic design parameters; the specific aerodynamic design parameters have been incorporated into the above description. Figures 1 to 7 Detailed examples have been provided, and will not be repeated here.

[0091] In one embodiment of this application, the partition plate device includes a first partition plate and a second partition plate, and the step of obtaining the wind-induced torque parameters of the vortex-induced vibration suppression system under the action of the target incoming wind includes:

[0092] Obtain the thrust torque generated by the first partition plate under the action of the target incoming airflow;

[0093] Obtain the drag torque generated by the second partition plate under the action of the target incoming airflow;

[0094] The wind-induced torque parameters are determined based on the driving torque and the resisting torque.

[0095] Specifically, the first partition and the second partition are not specifically defined as... Figures 1 to 7In this embodiment, the first and second partition plates are functionally defined. The first partition plate is used to characterize the partition plate that can generate thrust for the rotation of the vortex-induced vibration suppression system under the action of the target incoming wind. The second partition plate is used to characterize the partition plate that hinders the rotation of the vortex-induced vibration suppression system and generates drag under the action of the target incoming wind. Therefore, when the angle of attack of the target incoming wind and the vortex-induced vibration suppression system are different, the two partition plates of this application may be interchanged. For example, if a certain partition plate can generate thrust for the rotation of the vortex-induced vibration suppression system under the action of the target incoming wind, then this partition plate is the first partition plate; when the angle of attack changes to a certain angle, this partition plate changes from generating thrust to generating drag, and then this partition plate changes from the first partition plate to the second partition plate.

[0096] Furthermore, the angle of attack formed by the vortex-induced vibration suppression system and the direction of the incoming airflow to the target can be as follows: Figure 9 As shown, the angle formed between the direction of the incoming airflow and the central axis of the vortex-induced vibration suppression system, which is the central axis of the two partition plates, is called the angle of attack. It should be noted that the angle of attack can change during rotation; therefore, a dynamic angle of attack is defined subsequently using formulas. The concept of the angle of attack is consistent with that of the dynamic angle of attack.

[0097] In one embodiment of this application, obtaining the driving torque generated by the first partition plate under the action of the target incoming airflow includes:

[0098] The following parameters are obtained: the incoming wind speed of the target incoming wind, the characteristic diameter of the vortex-induced vibration suppression system, the air density of the environment in which the circular cylindrical structure is located, the first length of the first partition plate, and the drag coefficient of the vortex-induced vibration suppression system under the action of the target incoming wind.

[0099] The thrust experienced by the first partition plate under the action of the target incoming wind is determined based on the incoming wind speed, the characteristic diameter, the air density, the first length, and the drag coefficient.

[0100] The diameter of the circular cylindrical structure, the first distance between the first partition plate and the outer surface of the circular cylindrical structure, and the dynamic angle of attack formed by the direction of the target incoming wind and the central axis of the vortex vibration suppression system are obtained.

[0101] The thrust, diameter, first distance, first length, and dynamic wind angle of attack are input into a preset first calculation formula to obtain the thrust torque;

[0102] The preset first calculation formula is as follows:

[0103]

[0104] In the formula, For the thrust, For the diameter, The first length of the first partition plate. The dynamic wind angle of attack, For the first distance, The driving torque is described above.

[0105] Specifically, thrust It can be obtained through the following formula:

[0106]

[0107] In the formula. The drag coefficient, This refers to air density. The incoming air velocity of the target airflow. The characteristic diameter of the mechanism system (vortex vibration suppression system) This is the first length of the first partition plate. It should be noted that the dynamic wind angle of attack may change as the vortex-induced vibration suppression system rotates.

[0108] The step of obtaining the drag torque generated by the second partition plate under the action of the target incoming airflow includes:

[0109] The second length of the second partition plate and the second distance between the second partition plate and the outer surface of the circular column structure are obtained, and the resistance of the second partition plate under the action of the target incoming wind is determined according to the incoming wind speed, the characteristic diameter, the air density, the second length and the drag coefficient.

[0110] The drag force torque is obtained by inputting the drag, the diameter, the second distance, the second length, and the dynamic wind attack angle into a preset second calculation formula.

[0111] The preset second calculation formula is as follows:

[0112]

[0113] In the formula, For the resistance, For the diameter, The second length of the second partition plate. The dynamic wind angle of attack, The second distance, The drag torque is the stated drag force.

[0114] Specifically, resistance It can be obtained through the following formula:

[0115]

[0116] In the formula, The drag coefficient, This refers to air density. The incoming air velocity of the target airflow. The characteristic diameter of the mechanism system (vortex vibration suppression system) This is the second length of the second partition plate. It should be noted that the dynamic wind angle of attack may change as the vortex-induced vibration suppression system rotates.

[0117] In one embodiment of the application, the wind-induced torque parameter is obtained by the following formula:

[0118] In the formula, The wind-induced torque parameter, The driving torque, The drag torque is the stated drag force.

[0119] Specifically, the calculation of the wind-induced torque parameters can be detailed using the following formula:

[0120]

[0121] In step S2, the frictional torque parameters experienced by the vortex-induced vibration suppression system when it rotates around the cylindrical structure are obtained.

[0122] In one embodiment of this application, obtaining the frictional torque parameters experienced by the vortex-induced vibration suppression system when rotating around the cylindrical structure includes:

[0123] The material density of the partition plate device, the number of partition plates, the overall size parameters of the partition plates, the mass parameters of the pulley device, the dynamic friction coefficient of the pulley device, the diameter of the circular cylindrical structure, and the distance between the partition plate device and the outer surface of the circular cylindrical structure are obtained.

[0124] The material density, quantity, overall size parameters, mass parameters, dynamic friction coefficient, distance, diameter, and gravitational acceleration are input into a preset third calculation formula to obtain the friction torque parameters.

[0125] The preset third calculation formula is as follows:

[0126]

[0127] In the formula, The number of the partitions. The overall size parameters are as follows. The density of the material is... The quality parameter is... It is the acceleration due to gravity. The coefficient of dynamic friction is... For the diameter, The distance between the partition plate device and the outer surface of the circular column structure is [missing information]. The friction torque parameter is... This represents frictional resistance.

[0128] Specifically, The density of the material of the partition plate is given. As exemplarily mentioned above, the partition plate is made of aluminum.

[0130] In one embodiment of this application, adjusting the aerodynamic design parameters of the vortex-induced vibration suppression system includes:

[0131] Choose one or more of the following five adjustment methods as the target adjustment method: adjust the number of the partitions, adjust the included angle between the partitions, adjust the overall size parameters of the partitions, adjust the opening parameters of the partitions, and adjust the number of pulleys.

[0132] The aerodynamic design parameters of the vortex vibration suppression system are adjusted according to the target adjustment method.

[0133] Specifically, there can be multiple adjustment methods. Although this application embodiment only embodies five adjustment methods, including adjusting the number of the partition plates, adjusting the included angle between each partition plate, adjusting the overall size parameters of each partition plate, adjusting the opening parameters of each partition plate, and adjusting the number of pulleys, these five adjustment methods are merely illustrative examples. Other adjustment methods may exist in other embodiments, which are not limited here.

[0134] In step S3, it is determined whether the wind-induced torque parameter is greater than the friction torque parameter. If not, the aerodynamic design parameters of the vortex vibration suppression system are adjusted until the wind-induced torque parameter is greater than the friction torque parameter.

[0135] Specifically, it is necessary to ensure that the wind-induced torque parameter is greater than the friction torque parameter so that the vortex vibration suppression system can enable the partition plate to rotate around the tower (circular column structure) through the pulley device under the action of the target incoming wind.

[0136] In step S4, if the wind-induced torque parameter is greater than the friction torque parameter, it is determined whether the wind angle of attack formed by the direction of the vortex-induced vibration suppression system and the direction of the target incoming wind at the wake of the target incoming wind is less than the preset wind angle of attack. If not, the aerodynamic design parameters of the vortex-induced vibration suppression system are adjusted until the wind angle of attack is less than the preset wind angle of attack.

[0137] Specifically, the wind angle of attack needs to be smaller than the preset wind angle of attack in order to demonstrate the suppression effect of applying the vortex-induced vibration suppression system.

[0138] In step S5, when the wind angle of attack is less than the preset wind angle of attack, the first vortex-induced vibration parameter of the circular cylindrical structure after the vortex-induced vibration suppression system is applied and the second vortex-induced vibration parameter of the circular cylindrical structure when the vortex-induced vibration suppression system is not applied are obtained.

[0139] Specifically, wind tunnel tests were conducted on the above-mentioned application scheme to verify its effectiveness in suppressing vibration. The vortex-induced vibration range of the tower (circular cylindrical structure) was measured after applying aerodynamic measures (i.e., applying the vortex-induced vibration suppression system described in this application). And vortex amplitude (i.e., the first vortex vibration parameter described in this application). And the vortex vibration range of the tower when no aerodynamic measures are applied (i.e., the vortex vibration suppression system described in this application is applied). And vortex amplitude (i.e., the second vortex vibration parameter described in this application). If simultaneously satisfied... and If the condition is met, the solution is applicable; otherwise, adjustments are needed. The control effect of the aerodynamic measures can be adjusted by changing the angle between the partitions and the shape of the partitions.

[0140] In step S6, if the first vortex vibration parameter is greater than or equal to the second vortex vibration parameter, the aerodynamic design parameters of the vortex vibration suppression system are adjusted until the first vortex vibration parameter is less than the second vortex vibration parameter.

[0141] Specifically, the overall flowchart can be as follows: Figure 10 As shown, through continuous experimentation, suitable aerodynamic design parameters were finally found to suppress the vortex-induced vibration effect caused by the incoming target airflow. Among these, Figure 10 The target angle of attack shown is the preset angle of attack described in this application. The specific value of the preset angle of attack can be set as needed.

[0142] The following are some extended examples of adjusting the design parameters of aerodynamic measures in the embodiments of this application:

[0143] Furthermore, the annular track of this application has adjustable diameter, adjustable tilt angle, and replaceable track, making it suitable for tower structures (circular column structures) of different diameters and pulley devices of different specifications. The pulley device is used to support the weight of the mechanical parts of the entire vortex-induced vibration suppression system and the partition plate itself, and the size and load-bearing capacity of the pulley device can be arbitrarily changed.

[0144] Furthermore, the diaphragm is a fan-shaped structure concentric with the circular column structure, connecting the pulley devices and bolted connecting plates on both sides. The diaphragm is telescopic, providing lateral support for the partition plates and adjusting the angle between them. The vertical connecting shaft connects the upper pulley group, the lower pulley group, and the central connecting block. The bolted connecting plate connects the upper pulley group, the lower pulley group, and the partition plates. The distance between the outer surface of the circular column structure and the partition plates can be adjusted by changing the connection position between the bolted connecting plate and the partition plates.

[0145] The perforated plate partition is made of lightweight, high-strength material. The partition is replaceable, and its perforation parameters are adjustable, including perforation size, shape, and distribution. For example... Figure 11 and Figure 12 As shown, Figure 11 and Figure 12 These are two different partition plates with varying orifice sizes, shapes, and distributions. Because of these differences in orifice size, shape, and distribution, the ventilation methods for the incoming airflow to the target area also differ, resulting in varying vortex-induced vibration suppression effects.

[0146] It should be noted that some specific parameters of this application, such as the incoming air velocity of the target airflow, the diameter of the circular column structure, and the distance between the partition plate and the outer surface of the circular column structure, can be detected by some specific sensors, and will not be described here.

[0147] The following provides an exemplary description of the specific application of the embodiments of this application:

[0148] The wind force experienced by a single partition plate under the action of wind force for:

[0149] Among them, the wind-induced drag coefficient of the entire vortex-induced vibration suppression system under this working condition was obtained by CFD modeling and calculation of the existing device. It is 2.3; Let the air density be denoted as . ; The incoming wind speed is given. Since the initial vortex-induced vibration of the tower occurs at a wind speed of approximately 3 m / s (which can be obtained through experimental analysis or empirical values), the following values ​​are taken: and Perform calculations; The characteristic width of the separator is taken here. ; Let's take the length of the divider. .

[0150] The vortex-induced vibration suppression system consists of two partition plates at a 90° angle. Under the influence of the incoming target airflow, the partition plates rotate to the wake of the incoming airflow, eventually reaching a state of equilibrium. Figure 13 As shown. This application introduces the definition of wind angle of attack (dynamic wind angle of attack). That is, when the two partition plates are symmetrically positioned at the wake of the target incoming wind, that is, when the central axis of the two partition plates is aligned with the direction of the target incoming wind at the wake, the angle of attack is... At this point, the vortex-induced vibration suppression system is in a state of equilibrium, and the wind-induced torque it experiences is... Therefore, it can be concluded that, within a certain range, the angle of wind attack... The larger the wind torque The larger the value, the greater the wind-induced torque parameter on the entire vortex-induced vibration suppression system. for:

[0151] in, and These represent the forces acting on the first partition plate that pushes the entire vortex-induced vibration suppression system to rotate under the influence of the wind-induced torque parameters, and the forces acting on the second partition plate that prevent the vortex-induced vibration suppression system from rotating. and They are respectively in and Under the influence of the vortex-induced vibration suppression system, the torque on the wind turbine tower (circular cylindrical structure) is measured. Let be the diameter of the wind turbine tower (a circular cylindrical structure). ; The length of the first partition plate, The length of the second partition plate is taken here. and Both are 7 meters; The angle of attack is denoted as . The variation of wind-induced torque parameters under different wind angles of attack is shown in the following graph. Figure 14 As shown.

[0152] During the process of the separator rotating to the wake of the incoming flow under the action of wind-induced torque parameters, the entire vortex-induced vibration suppression system experiences frictional resistance. for:

[0153]

[0154] in, The number of partitions, at this time, is taken as... ; These are the length, width, and thickness of the partition, respectively. ; Let be the porosity of the separator, and take . ; This refers to the density of aluminum, which is also the density of the material in the partition plate. ; The total mass of the pulley system. , ; It is the acceleration due to gravity. ; The coefficient of dynamic friction of the pulley system is denoted as . .

[0155] The frictional torque parameters of the entire vortex-induced vibration suppression system around the center of the cylindrical structure for:

[0156] in Let be the diameter of the cylindrical structure, then take . ; Let's take the length of the divider. ; This represents the resistance experienced by the entire system on the circular track, also known as frictional resistance. The calculated frictional resistance parameters for the vibration damping measures are shown below. Figure 14 .

[0157] because Figure 14 It can be seen that the wind speed Under these circumstances, the wind-induced torque parameters of the overall vortex-induced vibration suppression system A graph showing the numerical variation of relative wind angle of attack (dynamic wind angle of attack). Wind torque parameters are used. Greater than the friction torque parameter Operating conditions: It can be seen that when the wind speed At that time, the angle of attack of the wind Requires an angle greater than 10°; when wind speed Angle of attack The angle of attack must be greater than 5°. If the wind angle of attack meets the requirements, the solution can be used; otherwise, a redesign is required, which means adjusting the aerodynamic design parameters of the vortex-induced vibration suppression system.

[0158] Next, after obtaining the proposed solution from the above calculations, a model of the vortex-induced vibration suppression system will be built and subjected to wind tunnel testing for further verification. If the model cannot rotate effectively, the solution can be adjusted (i.e., the aerodynamic design parameters of the vortex-induced vibration suppression system can be adjusted). This adjustment is mainly achieved by changing the size of the partition plate or the specifications of the sliding device. It should be noted that... Figure 14 and Figure 15 The torque on the vertical axis represents the wind-induced torque parameter.

[0159] Changing the size of the separator plate can improve the overall wind-induced torque parameters of the vortex-induced vibration suppression system. For example, the width of the partition is changed from... Raise to Calculations show Figure 15 It can be clearly observed that when the wind speed... At that time, the angle of attack of the wind Requires an angle greater than 5°; when wind speed Angle of attack The angle of attack needs to be greater than 3°. It can be seen that the required angle of attack has been significantly reduced after the aerodynamic design parameters have been adjusted.

[0160] The next step is to verify the effectiveness of the aerodynamic control measures. Wind tunnel tests will be conducted on the above-mentioned application scheme to verify its effectiveness in suppressing vibration. The vortex-induced vibration range of the tower (circular cylindrical structure) will be measured after applying the aerodynamic measures (i.e., applying the vortex-induced vibration suppression system described in this application). And vortex amplitude (i.e., the first vortex vibration parameter described in this application). And the vortex vibration range of the tower when no aerodynamic measures are applied (i.e., the vortex vibration suppression system described in this application is applied). And vortex amplitude (i.e., the second vortex vibration parameter described in this application). If simultaneously satisfied... and If the condition is met, the solution is applicable; otherwise, adjustments are needed. The control effect of the aerodynamic measures can be adjusted by changing the angle between the partitions and the shape of the partitions.
