[0040] In one embodiment of the present application, based on the above solution, the adjusting of the aerodynamic measure design parameters of the vortex vibration suppression system includes:
[0041] One or more adjustment methods are selected as target adjustment methods from the five adjustment methods of adjusting the number of the partition plates, adjusting the angles between the partition plates, adjusting the overall size parameters of the partition plates, adjusting the hole parameters of the partition plates, and adjusting the number of the pulleys;

[0045] The beneficial effect of the present application is that the present application applies a vortex vibration suppression system to the outer surface of a circular column structure, and the vortex vibration suppression system can rotate around the circular column structure under the action of a target incoming wind. By designing or adjusting the aerodynamic design parameters of the vortex vibration suppression system, the vortex vibration effect of the circular column structure caused by the target incoming wind can be reduced, thereby improving the safety of the circular column structure.
[0046] Furthermore, when the wind-induced torque parameter is greater than the friction torque parameter, it is determined whether the wind attack angle formed by the vortex-oscillation suppression system and the direction of the target incoming wind at the wake of the target incoming wind is less than a preset wind attack angle. If the wind attack angle is greater than or equal to the preset wind attack angle, it means that the aerodynamic measure design parameters at this time do not meet the requirements of the wind attack angle and cannot effectively reduce the vortex-oscillation effect caused by the target incoming wind. At this time, the aerodynamic measure 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.
[0047] Furthermore, merely meeting the requirements for the wind attack angle is not sufficient to reduce the vortex-oscillation effect. Therefore, on the basis of meeting the requirements for the wind attack angle, it is necessary to obtain the first vortex-oscillation parameter to which the circular column structure is subjected after the vortex-oscillation suppression system is applied, and compare it with the second vortex-oscillation parameter to which the circular column structure is subjected when the vortex-oscillation suppression system is not applied, so as to determine whether the vortex-oscillation suppression system applied in the present application can effectively reduce the vortex-oscillation effect. If not, then readjust the aerodynamic measure design parameters of the vortex-oscillation suppression system until the first vortex-oscillation parameter after the vortex-oscillation suppression system is applied is significantly lower than the second vortex-oscillation parameter when the vortex-oscillation suppression system is not applied, thereby reducing the vortex-oscillation effect caused by the target incoming wind, or directly suppressing the occurrence of the vortex-oscillation effect.
[0048] Therefore, the present application verifies the design parameters of the aerodynamic measures, and when the set requirements are not met, continuously adjusts the design parameters of the aerodynamic measures to enable the vortex-oscillation suppression system to rotate to the wake of the target incoming wind under the action of the target incoming wind, thereby effectively reducing the vortex-oscillation effect of the circular column structure or directly suppressing the occurrence of the vortex-oscillation effect.

[0077] The following is an exemplary description of the installation method of the vortex vibration suppression system and the specific size parameters of each component (i.e., the design parameters of the aerodynamic measures described in the embodiment of the present application):

[0082] The upper pulley block 120 of the present application is a rectangular shell structure equipped with pulleys, the length of the upper surface is 510mm, the width is 300mm, the length of the lower surface is 445mm, the width is 300mm, the overall height is 310mm, and the thickness is 10mm; the diameter of the vertical main pulley 121 is 150mm.

In other embodiments, the installation method may be changed, and the number of components and the specific parameters of each component may also be adjusted. In other words, the design parameters of the aerodynamic measures described in the embodiments of the present application can be adjusted arbitrarily as needed and are not limited here.
[0086] The implementation details of the technical solution of the embodiment of the present application are described in detail below:
[0087] According to one aspect of an embodiment of the present application, a vortex vibration suppression method based on a circular column structure is provided, which is applied to a vortex vibration suppression system. The vortex vibration suppression system can rotate around the circular column structure under the action of a target incoming wind. Figure 8 This is a flow chart of a vortex vibration suppression method based on a circular column structure according to an embodiment of the present application. The method includes at least steps S1 to S6, which are described in detail as follows:
[0088] In step S1, wind-induced moment parameters to which the vortex-oscillation suppression system is subjected under the action of the target incoming wind are obtained, wherein the wind-induced moment parameters are used to make the vortex-oscillation suppression system rotate around the circular column structure.
[0089] Specifically, the wind speed of the target incoming wind can be set as needed. In the vortex vibration suppression method based on the circular column structure proposed in the present application, the incoming wind speed of the target incoming wind can be set to the minimum vortex vibration wind speed. The minimum vortex vibration wind speed is used to characterize the minimum wind speed corresponding to the vortex vibration effect of the circular column structure, that is, the vortex vibration effect can occur at the minimum vortex vibration wind speed. If the incoming wind speed of the target incoming wind is lower than the minimum vortex vibration wind speed, then the target incoming wind cannot cause the circular column structure to produce a vortex vibration effect. Of course, the incoming wind speed of the target incoming wind can also be set to other numerical wind speeds, not only limited to the minimum wind speed corresponding to the vortex vibration effect of the circular column structure, but also higher than the minimum vortex vibration wind speed. Then, the embodiment of the present application sets the incoming wind speed of the target incoming wind to the minimum vortex vibration wind speed first, so as to explore various situations that may occur in the circular column structure and the vortex vibration suppression system under the minimum vortex vibration wind speed.
[0090] In one embodiment of the present application, the vortex vibration suppression system includes a partition plate device, a pulley device and an annular track device surrounding the circular column structure, the pulley device slides in the annular track device and is connected to the partition plate device; under the action of the target incoming wind, the pulley device drives the partition plate device to rotate around the circular column structure; the aerodynamic measure design parameters include the number of partition plates in the partition plate device, the angles between each of the partition plates, the overall size parameters of each of the partition plates, the opening parameters of each of the partition plates and the number of pulleys in the pulley device.
[0091] Specifically, the specific component composition and installation method of the vortex vibration suppression system of the present application, and the size parameters of each component can be collectively referred to as aerodynamic measure design parameters; the specific aerodynamic measure design parameters have been combined in the above description. Figures 1 to 7 A detailed exemplary description has been given and will not be repeated here.
[0092] In one embodiment of the present application, the partition plate device includes a first partition plate and a second partition plate, and the step of obtaining the wind-induced moment parameter to which the vortex vibration suppression system is subjected under the action of the target incoming wind includes:
[0093] Obtaining the driving torque generated by the first partition plate under the action of the target incoming wind;
[0094] Obtaining the drag torque generated by the second partition plate under the action of the target incoming wind flow;
[0095] The wind-induced torque parameter is determined according to the propulsive torque and the resistive torque.
[0096] Specifically, the first partition plate and the second partition plate are not limited to Figures 1 to 7 Which partition plate is it? Here, the embodiment of the present application adopts functional definition of the first partition plate and the second partition plate. The first partition plate is used to characterize the partition plate that can generate thrust for the rotation of the vortex vibration suppression system under the action of the target incoming wind, and the second partition plate is used to characterize the partition plate that hinders the rotation of the vortex vibration suppression system and generates resistance under the action of the target incoming wind. Therefore, when the target incoming wind and the wind attack angle of the vortex vibration suppression system are different, the two partition plates of the present application may have the situation that the first partition plate and the second partition plate are interchangeable. For example, a certain partition plate at present can generate thrust for the rotation of the vortex vibration suppression system under the action of the target incoming wind, and at this time, the partition plate is the first partition plate; when the wind attack angle changes to a certain angle, the partition plate changes from generating thrust to generating resistance, and at this time, the partition plate changes from the first partition plate to the second partition plate.
[0097] Furthermore, the wind attack angle formed by the vortex vibration suppression system and the direction of the target incoming wind can be as follows: Fig. 9 As shown in the figure, the angle formed by the direction of the target incoming wind and the central axis of the vortex vibration suppression system, that is, the central axis of the two partitions, is called the wind attack angle. It should be noted that the wind attack angle can change during the rotation process, so a dynamic wind attack angle is defined in combination with the formula later. The concept of wind attack angle is consistent with that of dynamic wind attack angle.
[0098] In one embodiment of the present application, obtaining the driving torque generated by the first partition plate under the action of the target incoming wind includes:
[0099] Obtaining the incoming wind speed of the target incoming wind, the characteristic diameter of the vortex vibration suppression system, the air density of the environment in which the circular column structure is located, the first length of the first partition plate, and the drag coefficient of the vortex vibration suppression system under the action of the target incoming wind;
[0100] determining the thrust exerted on the first partition plate by the target incoming wind according to the incoming wind speed, the characteristic diameter, the air density, the first length and the drag coefficient;
[0101] Acquire the diameter of the circular column structure, the first distance between the first partition plate and the outer surface of the circular column structure, and the dynamic wind attack angle formed by the direction of the target incoming wind and the central axis of the vortex vibration suppression system;
[0102] Inputting the thrust, the diameter, the first distance, the first length, and the dynamic wind attack angle into a preset first calculation formula to obtain the propulsion torque;
[0103] Wherein, the preset first calculation formula is:
[0104]
[0105] In the formula, F D1 is the thrust, D is the diameter, L is the first length of the first partition plate, θ is the dynamic wind attack angle, l is the first distance, M D1 is the thrust torque.
[0106] Specifically, the thrust F D1 It can be obtained by the following formula:
[0107]
[0108] In the formula, C D is the drag coefficient, ρ is the air density. U is the incoming wind speed of the target incoming wind, D0 is the characteristic diameter of the mechanism system (vortex vibration suppression system), and L is the first length of the first partition plate. It should be noted that the dynamic wind attack angle may change as the vortex vibration suppression system rotates.
[0109] The step of obtaining the drag torque generated by the second partition plate under the action of the target incoming wind flow comprises:
[0110] Obtaining a second length of the second partition plate and a second distance between the second partition plate and the outer surface of the circular column structure, and determining the resistance of the second partition plate under the action of the target incoming wind according to the incoming wind speed, the characteristic diameter, the air density, the second length and the drag coefficient;
[0111] Input the resistance, the diameter, the second distance, the second length, and the dynamic wind attack angle into a preset second calculation formula to obtain the resistance torque;
[0112] Wherein, the preset second calculation formula is:
[0113]
[0114] In the formula, F D2 is the resistance, D is the diameter, L is the second length of the second partition plate, θ is the dynamic wind attack angle, l is the second distance, M D2 is the resisting torque.
[0115] Specifically, the resistance F D2 It can be obtained by the following formula:
[0116]
[0117] In the formula, C D is the drag coefficient, ρ is the air density. U is the incoming wind speed of the target incoming wind, D0 is the characteristic diameter of the mechanism system (vortex vibration suppression system), and L is the second length of the second partition plate. It should be noted that the dynamic wind attack angle may change as the vortex vibration suppression system rotates.
[0118] In one embodiment of the application, the wind-induced moment parameter is obtained by the following formula:
[0119] M D =M D1 -M D2
[0120] Where M D is the wind-induced moment parameter, M D1 is the thrust torque, M D2 is the resisting torque.
[0121] Specifically, the calculation of wind-induced moment parameters can be detailed by the following formula:

[0123] In step S2, the friction torque parameters to which the vortex vibration suppression system is subjected when rotating around the circular column structure are obtained.
[0124] In one embodiment of the present application, the step of obtaining the friction torque parameter to which the vortex vibration suppression system is subjected when rotating around the circular column structure includes:
[0125] Obtaining the material density of the partition plate device, the number of the 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 column structure, and the distance between the partition plate device and the outer surface of the circular column structure;
[0126] Inputting the material density, the quantity, the overall size parameter, the mass parameter, the dynamic friction coefficient, the distance, the diameter and the gravitational acceleration into a preset third calculation formula to obtain the friction torque parameter;
[0127] Wherein, the preset third calculation formula is:
[0128]
[0129] Where n1 is the number of partitions, A, B, δ are the overall size parameters, ρ 材 is the material density, m1 and m2 are the mass parameters, g is the gravitational acceleration, μ is the dynamic friction coefficient, D is the diameter, and l is the distance.
[0130] Specifically, ρ 材 is the material density of the partition plate. Since the material of the partition plate is aluminum as exemplarily mentioned above, then ρ 材 It can be specifically the material density of aluminum, expressed as ρ 铝 Then the third calculation formula can be expressed as ρ 铝 The changes are reflected as follows:
[0131]
[0132] In one embodiment of the present application, the adjusting of the aerodynamic measure design parameters of the vortex vibration suppression system includes:
[0133] Any one or more adjustment methods are selected as target adjustment methods from the five adjustment methods of adjusting the number of the partition plates, adjusting the angle between the partition plates, adjusting the overall size parameters of the partition plates, adjusting the opening parameters of the partition plates, and adjusting the number of the pulleys;
[0134] Adjust the design parameters of the aerodynamic measures of the vortex-induced vibration suppression system according to the described target adjustment method.
[0135] Specifically, there can be various adjustment methods. Although only five adjustment methods are reflected in the embodiments of the present application, including adjusting the number of the partition plates, adjusting the included angle between each of the partition plates, adjusting the overall dimension parameters of each of the partition plates, adjusting the opening parameters of each of the partition plates, and adjusting the number of the pulleys, these five adjustment methods are only for illustrative purposes. In other embodiments, there may be other adjustment methods, which are not limited herein.
[0136] In step S3, determine whether the wind-induced torque parameter is greater than the frictional torque parameter. If not, adjust the design parameters of the aerodynamic measures of the vortex-induced vibration suppression system until the wind-induced torque parameter is greater than the frictional torque parameter.
[0137] Specifically, it is necessary to ensure that the wind-induced torque parameter is greater than the frictional torque parameter so that the partition plates can rotate around the tower barrel (circular column structure) through the pulley device under the action of the target oncoming wind in the vortex-induced vibration suppression system.
[0138] In step S4, when the wind-induced torque parameter is greater than the frictional torque parameter, determine whether the wind attack angle formed by the vortex-induced vibration suppression system and the direction of the target oncoming wind at the wake of the target oncoming wind is less than the preset wind attack angle. If not, adjust the design parameters of the aerodynamic measures of the vortex-induced vibration suppression system until the wind attack angle is less than the preset wind attack angle.
[0139] Specifically, the wind attack angle needs to be less than the preset wind attack angle to reflect the suppression effect after applying the vortex-induced vibration suppression system.
[0140] In step S5, when the wind attack angle is less than the preset wind attack angle, obtain the first vortex-induced vibration parameter of the circular column structure after applying the vortex-induced vibration suppression system and the second vortex-induced vibration parameter of the circular column structure when the vortex-induced vibration suppression system is not applied.
[0141] Specifically, conduct a wind tunnel test on the above usage plan to verify whether vibration can be effectively suppressed. Measure the vortex-induced vibration interval I1 and the vortex-induced vibration amplitude A1 of the tower barrel (circular column structure) after applying the aerodynamic measures (that is, applying the vortex-induced vibration suppression system described in the present application) (i.e., the first vortex-induced vibration parameter described in the present application). And test the vortex-induced vibration interval I and the vortex-induced vibration amplitude A of the tower barrel when the aerodynamic measures are not applied (that is, applying the vortex-induced vibration suppression system described in the present application) (i.e., the second vortex-induced vibration parameter described in the present application). If both I1 < I and A1 < A are satisfied, the plan is applicable; otherwise, the plan needs to be adjusted. Adjust the control effect of the aerodynamic measures by changing the included angle between the partition plates and the shape of the partition plates.
[0142] In step S6, if the first vortex-oscillation parameter is greater than or equal to the second vortex-oscillation parameter, the aerodynamic measure design parameters of the vortex-oscillation suppression system are adjusted until the first vortex-oscillation parameter is less than the second vortex-oscillation parameter.
[0143] Specifically, the overall flow chart can be as follows: Fig.10 As shown in the figure, through continuous experiments, we finally found the appropriate aerodynamic design parameters to suppress the vortex vibration effect caused by the target incoming wind. Fig.10 The target wind attack angle shown is the preset wind attack angle mentioned in the present application. The specific value of the preset wind attack angle can be set as needed.
[0144] The following are some extensible example methods for adjusting the design parameters of the pneumatic measures in the embodiments of the present application:
[0145] Furthermore, the circular track of the present application has the functions of adjustable diameter, adjustable inclination angle and replaceable track, which can make the circular track suitable for tower structures (circular column structures) of different diameters and pulley devices of different specifications. The pulley device is used to bear the weight of the mechanical device part of the entire vortex vibration suppression system and the partition plate, and the size and bearing capacity specifications of the pulley device can be arbitrarily replaced.
[0146] Furthermore, the transverse partition is a fan-shaped structure with the same center as the circular column structure, connecting the pulley devices and bolt connection plates on the left and right sides. The transverse partition is retractable and can support the partition plate laterally and adjust the angle between the partition plates. The vertical connecting shaft can be used to connect the upper pulley block, the lower pulley block and the middle connecting block. The bolt connection plate can be used to connect the upper pulley block, the lower pulley block and the partition plate. The distance between the outer surface of the circular column structure and the partition plate can be adjusted by changing the connection position of the bolt connection plate and the partition plate.
[0147] The porous plate partition is made of light and high-strength material. The partition is replaceable and the opening parameters of the partition are adjustable, including the opening size, opening shape and opening distribution. Fig.11 and Fig.12 As shown, Fig.11 and Fig.12 There are two partition plates with different opening sizes, opening shapes and opening distribution methods. Due to the differences in opening sizes, opening shapes and opening distribution methods, the ventilation methods for the target incoming air flow are also different, and the vortex vibration suppression effects produced thereby are also different.
[0148] It should be noted that some specific parameters of the present application, such as the target incoming wind speed, the diameter of the circular column structure, the distance between the partition plate and the outer surface of the circular column structure, etc., can be detected by some specific sensors and will not be explained here.
[0149] The following is an exemplary description of the specific application implementation of the embodiments of the present application:
[0150] The wind force F on a single partition under the action of wind force D for:
[0151]
[0152] Among them, the wind-induced drag coefficient C of the entire vortex vibration suppression system under this condition is obtained by CFD modeling of the existing device. D is 2.3; ρ is the air density, ρ=1.29kg / m 3 ; U is the incoming wind speed. Since the wind speed at which the initial vortex vibration of the tower occurs is about 3m / s (which can be obtained from experimental analysis or empirical values), U=4m / s and U=5m / s are taken for calculation respectively; D0 is the characteristic width of the partition plate, and D0=1.5m is taken at this time; L is the length of the partition plate, and L=7m is taken at this time.
[0153] The vortex vibration suppression system is composed of two partitions, the angle between the two partitions is 90°. Under the action of the target wind flow, the partition will rotate to the tail of the target wind flow and finally reach a balanced state. Fig.13 This application introduces the definition of wind attack angle (dynamic wind attack angle) θ, that is, when the two partitions are symmetrically located at the wake of the target incoming wind, that is, the central axis of the two partitions is consistent with the direction of the target incoming wind at the wake, the wind attack angle θ = 0, and the vortex vibration suppression system is in a balanced state as a whole, and the wind-induced torque M it is subjected to D =0. It can be seen that within a certain range, the larger the wind attack angle θ is, the greater the wind-induced moment M D The larger the wind-induced moment parameter M of the vortex vibration suppression system as a whole D for:
[0154]
[0155] Among them, F D1 and F D2 are the force on the first partition plate that drives the entire vortex vibration suppression system to rotate under the action of the wind-induced moment parameter and the force on the second partition plate that prevents the vortex vibration suppression system from rotating; M D1 and M D2 In F D1 and F D2 Under the action of vortex vibration suppression system, the torque of wind turbine tower (circular column structure); D is the diameter of wind turbine tower (circular column structure), in this case, D=3m; L is the length of the first partition plate or the second partition plate (the length of the first partition plate and the second partition plate is the same in this embodiment), in this case, L=7m; θ is the wind attack angle. It is calculated that the change diagram of wind-induced moment parameters under different wind attack angles can be shown as follows: Fig.14 shown.
[0156] When the partition plate rotates to the incoming flow wake under the action of the wind-induced moment parameter, the friction resistance f of the entire vortex vibration suppression system is:
[0157] f=[n1×(1-P)×A×B×δ×ρ 铝 +m1+m2]×g×μ
[0158] Where n1 is the number of partition plates, in this case n1=2; A, B, δ are the length, width and thickness of the partition plates, A=7m, B=0.9m, δ=2mm; P is the porosity of the partition plates, P=20%; ρ 铝 is the density of aluminum, i.e. the material density of the partition plate, ρ 铝 =2700kg / m 3 ; m1+m2 is the total mass of the pulley device, m1=32kg, m2=68kg; g is the acceleration due to gravity, g=9.8m / s 2 ; μ is the dynamic friction coefficient of the pulley device, μ=0.02.
[0159] The friction torque parameter M of the entire vortex vibration suppression system around the center of the circular column structure is f for:
[0160]
[0161] Where D is the diameter of the circular column structure, in this case D = 3m; L is the length of the partition plate, in this case L = 7m; f is the resistance of the entire system on the circular track. The friction resistance parameters of the vibration suppression measures are calculated and shown in Fig.14 .
[0162] because Fig.14 It can be seen that when the wind speed is U = 4m / s and U = 5m / s, the wind-induced moment parameter M of the vortex vibration suppression system as a whole is D The value of the relative wind angle of attack (dynamic wind angle of attack) varies. Take the wind-induced moment parameter M D Greater than the friction torque parameter M f Working conditions: It can be seen that when the wind speed U=4m / s, the wind attack angle θ needs to be greater than 10°; when the wind speed U=5m / s, the wind attack angle θ needs to be greater than 5°. If the wind attack angle meets the requirements, the solution is used, otherwise it needs to be redesigned, that is, the aerodynamic design parameters of the vortex vibration suppression system are adjusted.
[0163] Next, after obtaining the above-mentioned usage plan through calculation, fabricate a model of the vortex-induced vibration suppression system in this plan and conduct a wind tunnel test for re-verification. If the model cannot rotate effectively, the plan can be adjusted (i.e., adjust the design parameters of the aerodynamic measures of the vortex-induced vibration suppression system). The plan adjustment is mainly achieved by changing the size of the partition plate or the specifications of the sliding device. It should be noted that Fig.14 and Fig.15 the moment represented by the ordinate of is the wind force moment parameter.
[0164] Changing the size of the partition plate can increase the wind force moment parameter M received by the overall vortex-induced vibration suppression system D . For example, increase the width of the partition plate from D0 = 0.9m to D0 = 1.5m. As calculated in Fig.15 . It can be clearly found that when the wind speed U = 4m / s, the wind attack angle θ needs to be greater than 5°; when the wind speed U = 5m / s, the wind attack angle θ needs to be greater than 3°. Thus, it can be seen that the required wind attack angle decreases significantly after adjusting the design parameters of the aerodynamic measures.
[0165] Next, test the control effect of the aerodynamic measures. Conduct a wind tunnel test on the above-mentioned usage plan to verify whether vibration can be effectively suppressed. Measure the vortex-induced vibration interval I1 and the vortex-induced vibration amplitude A1 (i.e., the first vortex-induced vibration parameter described in this application) of the tower barrel (circular column structure) after applying the aerodynamic measures (that is, applying the vortex-induced vibration suppression system described in this application). And test the vortex-induced vibration interval I and the vortex-induced vibration amplitude A (i.e., the second vortex-induced vibration parameter described in this application) of the tower barrel when no aerodynamic measures are applied (that is, applying the vortex-induced vibration suppression system described in this application). If both I1 < I and A1 < A are satisfied, this plan is applicable; otherwise, the plan needs to be adjusted. Adjust the control effect of the aerodynamic measures by changing the angle between the partition plates and the shape of the partition plates.
