Description

Technical Field

[0001] The present application relates to the technical field of liquid sloshing suppression, and in particular to a method, apparatus, system, computing device, and storage medium for suppressing liquid sloshing. Background Art

[0002] Liquid tanks, as important storage media for liquid materials, are crucial for the storage and transportation of liquid fuels like petroleum and liquefied natural gas, as well as other liquid materials. They are widely used in aerospace, marine engineering, and other fields. Liquids within tanks can experience motion under external stimuli, a phenomenon known as liquid sloshing. The forces generated by sloshing liquids acting on the tank walls can affect the tank structure, making it necessary to control sloshing.

[0003] In the related art, liquid sloshing is suppressed by installing a damping mechanism in the liquid tank, which includes a fixed damping mechanism and a passive floating damping mechanism. The fixed damping mechanism has high design and use costs and cannot be quickly adjusted to different liquid depths. The passive floating damping mechanism moves with the liquid and has limited ability to eliminate liquid sloshing. Summary of the Invention

When the liquid tank is stimulated by the outside world, the central detection unit can effectively detect key wave data such as the incident wave height, the reflected wave height and the transmitted wave height, so as to accurately determine the target radiation wave height at the central detection unit, determine the target motion amplitude of the structure based on the mapping relationship, and control the movement of the structure based on the amplitude, so that the wall wave height at the side wall is maintained within the target range. This method can improve the effectiveness of suppressing liquid sloshing in the liquid tank, reduce the impact and pressure of the liquid on the side wall of the liquid tank, and enhance the safety and stability of the liquid tank.

[0055] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the specific implementation of the present application will be clearly and completely described below in conjunction with the drawings in the implementation of the present application.

[0056] The present application provides a method for suppressing liquid sloshing, such as Figure 1 As shown, the method includes the following steps:

[0057] Step 101: Determine the immersion depth of the structure in the liquid. A central detection unit is provided between the structure and the side wall of the liquid tank. When the structure moves in the liquid with an initial motion amplitude, the initial radiation waves generated by the movement of the structure are detected based on the central detection unit.

[0058] A structure is set in the liquid tank. The immersion depth can reflect the specific depth of the structure immersed in the liquid, which can be determined by a sensor or any other method that can determine its depth. A central detection unit is arranged between the structure and the side wall of the liquid tank. When the structure moves in the liquid with a preset initial motion amplitude, the central detection unit will detect the initial radiation waves caused by the movement of the structure. It should be noted that the structure can be a functional device for suppressing the sloshing of liquid in the liquid tank, such as a damping structure. Among them, the central detection unit, as a key measuring component, is located between the structure and the side wall of the liquid tank. The main function of the central detection unit can be to monitor the fluctuation of the liquid.

[0059] Furthermore, according to the principles of fluid mechanics, the movement of structures in liquids will cause disturbances to the liquid, thereby generating radiation waves. The central detection unit can obtain key physical quantities of these initial radiation waves, such as wave height, wavelength, frequency and other information through detection.

[0060] For example, taking a liquid tank for transporting oil as an example, when the damping structure therein starts to move with an initially set motion amplitude, the central detection unit will measure the initial radiation waves generated by its movement in the oil, and adjust the motion amplitude, frequency and other parameters of the damping structure based on the data obtained.

[0061] Step 102: Determine a preset distance between the structure and the central detection unit and an initial radiation wave height at the central detection unit based on the initial radiation wave, and establish a mapping relationship between the immersion depth, the preset distance, the initial radiation wave height, and the initial motion amplitude;

[0062] Based on the detected initial radiation waves, several important parameters are determined, including the preset distance between the structure and the central detection unit and the initial radiation wave height at the central detection unit. The preset distance can be a pre-set physical quantity that affects the characteristics of the waves generated by the structure's motion as they are transmitted to the central detection unit. The initial radiation wave height reflects the energy of the initial radiation wave at the central detection unit.

[0063] Furthermore, a mapping relationship is established between the immersion depth, preset distance, initial radiation wave height, and initial motion amplitude. This mapping relationship can show the intrinsic connection between each parameter. A large amount of experimental data can be analyzed by machine learning system to summarize how different parameters affect each other. The resulting mapping relationship is and , where the immersion depth is d, the initial motion amplitude is xb, the preset distance between the central detection unit and the structure is L, and the initial radiation wave height is η t It should be noted that when the central detection units are set on both sides of the structure (for example, distributed on the left and right sides of the structure), the initial radiation wave height is η t Including the middle detection unit determined by the left side of the structure η l , and the middle detection unit determined by the right side of the structure η r , in order to determine the above mapping relationship.

[0064] In some examples, when considering the phenomenon of time-delay processing, η l and η r The value at time t' is the value obtained by adding the motor control response time / value calculation adjustment time △t to the current time t.

[0065] It should be noted that the establishment of the mapping relationship can provide a basis for subsequent operations. It can predict the corresponding radiation wave height and motion amplitude according to different immersion depths, preset distances and other conditions, or adjust the immersion depth and preset distance of the structure according to the expected radiation wave height and motion amplitude.

[0066] Step 103: In the presence of external excitation in the liquid tank, wave data is detected based on the central detection unit. The wave data includes the wave height of the incident wave from the side wall to the central detection unit, the wave height of the reflected wave reflected from the structure to the central detection unit, and the wave height of the transmitted wave from the structure to the central detection unit.

[0067] External excitation can refer to the influence of some factors from outside the liquid tank on the liquid in the liquid tank, such as the acceleration, deceleration, and turning of the transportation vehicle where the liquid tank is located, or the vibration and wind force of the external environment. External excitation can cause complex fluctuations in the liquid in the liquid tank.

[0068] Furthermore, wave data under external excitation is detected based on the central detection unit. The detected wave data includes the wave height of the incident wave from the side wall to the central detection unit, the wave height of the reflected wave reflected from the structure to the central detection unit, and the wave height of the transmitted wave passing through the structure to the central detection unit.

[0069] Among them, the wave height of the incident wave from the side wall to the middle detection unit can reflect the height of the incident wave propagating from the side wall of the liquid tank to the middle detection unit under the action of external excitation, and its height is related to the intensity of the external excitation and the characteristics of the liquid; the wave height of the reflected wave reflected from the structure to the middle detection unit can reflect the reflection ability of the structure to the incident wave, and its size is affected by the physical properties of the structure and the incident wave; the wave height of the transmitted wave through the structure to the middle detection unit can reflect the wave energy of the incident wave that continues to propagate to the middle detection unit after passing through the structure, and its height is affected by the permeability of the structure and its ability to attenuate waves.

[0070] By detecting wave data, we can understand the wave propagation and energy distribution in different directions in the liquid tank under external excitation, provide a data basis for subsequent analysis and control, and then help evaluate the performance of the structure under different external excitations, so as to adjust the parameters of the structure or take other control measures.

[0071] Step 104: Determine the target radiation wave height at the middle detection unit based on the wave data, determine the target motion amplitude of the structure based on the target radiation wave height and the mapping relationship, and control the movement of the structure according to the target motion amplitude so that the wall wave height at the side wall is within the target range.

[0072] Based on the wave data obtained in step 103, namely, the incident wave height from the side wall to the middle detection unit, the reflected wave height reflected from the structure to the middle detection unit, and the transmitted wave height through the structure to the middle detection unit, the target radiation wave height at the middle detection unit is determined.

[0073] Based on the target radiation wave height and the mapping relationship established in step 102 between the immersion depth, preset distance, radiation wave height, and motion amplitude, the target motion amplitude of the structure is determined. This mapping relationship can determine the intrinsic relationship between various parameters. Therefore, when the target radiation wave height is known, the corresponding target motion amplitude of the structure can be inferred from this mapping relationship. Furthermore, the movement of the structure is controlled based on the calculated target motion amplitude. By adjusting the structure's motion state, the liquid's wave motion is affected, ensuring that the wall wave height at the sidewall is within the target range.

[0074] It should be noted that the wall wave height at the side wall is within the target range to ensure that the liquid fluctuations in the tank will not cause excessive pressure and impact on the side wall of the tank, avoiding problems such as damage to the tank structure and liquid leakage that may be caused by excessive liquid sloshing.

[0075] In this embodiment, the method can accurately detect the initial radiation waves generated by the movement of the structure by setting a structure and a central detection unit in the liquid tank, and then determine the preset distance between the structure and the central detection unit and the initial radiation wave height, and construct a mapping relationship between the above parameters and the initial motion amplitude. When the liquid tank is stimulated by the outside world, the central detection unit can effectively detect key wave data such as the incident wave height, the reflected wave height, and the transmitted wave height, thereby accurately determining the target radiation wave height at the central detection unit, determining the target motion amplitude of the structure based on the mapping relationship, and controlling the movement of the structure based on this amplitude, so that the wall wave height at the side wall is maintained within the target range. This method can achieve the effect of suppressing the rise of side wall waves, reduce the impact and pressure of the liquid on the side wall of the liquid tank, and enhance the safety and stability of the liquid tank.

[0076] In one embodiment, the interior of the tank is as follows Figure 2 As shown, W1, W2, W3, and W4 are the first wall detection unit, the first middle detection unit, the second middle detection unit, and the second wall detection unit. represents the first wall wave height, represents the height of the first incident wave, represents the height of the first reflected wave, Indicates the first target radiation wave height, represents the first transmitted wave height, represents the second wall wave height, represents the height of the second incident wave, Represents the second reflected wave height, Indicates the second target radiation wave height, The first preset distance is L1 and the second preset distance is L2.

[0077] In one embodiment, Figure 3 As shown, wall detection units are provided on two opposite side walls of the liquid tank, and a central detection unit is provided between the structure and the wall detection units. Before controlling the movement of the structure according to the target movement amplitude, the method further includes the following steps:

[0078] Step 301: Detecting a first wall wave height using a first wall detection unit on one side of the structure, and detecting a second wall wave height using a second wall detection unit on the other side of the structure;

[0079] The first wall detection unit located on one side of the structure detects the first wall wave height, which reflects the impact of liquid fluctuations on the tank wall on that side. Similarly, the second wall detection unit on the other side of the structure detects the second wall wave height, which reflects the liquid fluctuations on the other side of the tank wall.

[0080] By detecting the first wall wave height and the second wall wave height, the liquid wave state on the walls on both sides of the liquid tank can be understood, providing more accurate and comprehensive information for subsequent structure motion control.

[0081] Step 302: In the presence of external excitation in the liquid tank, determine the sloshing form of the liquid in the liquid tank according to the difference between the first wall wave height and the second wall wave height, and optimize the target motion amplitude according to the sloshing form.

[0082] The sloshing pattern of the liquid in the tank is determined based on the difference between the first wall wave height detected by the first wall detection unit and the second wall wave height detected by the second wall detection unit. Different sloshing patterns can result in different differences in the wall wave heights on both sides. By analyzing this difference, the flow and sloshing patterns of the liquid in the tank can be determined, such as whether the liquid is sloshing in a conventional manner, sloshing with a special waveform, sloshing symmetrically or asymmetrically, or exhibiting a specific periodic sloshing pattern.

[0083] The target motion amplitude is optimized based on the determined sloshing form. It should be noted that different sloshing forms require different motion responses from the structure. For some sloshing forms, the target motion amplitude may need to be increased to better suppress sloshing, while for other sloshing forms, the target motion amplitude may need to be reduced or other parameters such as the frequency and direction of the motion may need to be adjusted. In this way, adjusting the motion amplitude of the structure to the state that best suits the current sloshing form can more effectively suppress liquid sloshing and ensure that the liquid in the tank remains relatively stable under various external excitations.

[0084] In this embodiment, this method employs wall detection units installed on opposite sides of the tank, as well as a central detection unit between the structure and the wall detection units. Before controlling the structure's motion, the method detects the first and second wall wave heights and determines the sloshing form based on the difference between the two, thereby optimizing the target motion amplitude. This method offers multiple technical advantages. This allows the control of the structure's motion to be more closely aligned with the actual sloshing conditions of the liquid within the tank, enhancing the specificity and effectiveness of suppressing liquid sloshing. Furthermore, determining the sloshing form helps adjust the structure's motion amplitude, reducing the impact of the liquid on the wall and improving the stability of the tank structure.

[0085] In one embodiment, the sloshing form includes a conventional sloshing form, and the target motion amplitude is optimized according to the sloshing form of the liquid tank, including:

[0086] If the difference is outside the set threshold range, the swaying form is determined to be a conventional swaying form. When the difference is greater than 0, the structure is controlled to move in the direction of the first wall detection unit with a target motion amplitude; when the difference is less than 0, the structure is controlled to move in the direction of the second wall detection unit with a target motion amplitude.

[0087] Specifically, if the difference between the calculated first and second wall wave heights falls outside a set threshold, the sloshing behavior of the liquid in the tank can be determined to be normal sloshing. Under this normal sloshing behavior, the direction of the structure's motion can be controlled based on the positive or negative sign of the difference.

[0088] If the difference is greater than 0, it means that the wave height of the first wall is higher than the wave height of the second wall, and the liquid tends to fluctuate toward the side where the first wall detection unit is located. The structure can be controlled to move toward the first wall detection unit with a target motion amplitude. The purpose is to suppress the fluctuation on this side by moving the structure toward the first wall detection unit to balance the liquid sloshing in the liquid tank.

[0089] If the difference is less than 0, it means that the second wall wave height is higher than the first wall wave height, and the liquid tends to fluctuate toward the side where the second wall detection unit is located. The structure can be controlled to move toward the second wall detection unit with a target motion amplitude. The purpose is to suppress the fluctuation on this side by moving the structure toward the second wall detection unit to balance the liquid sloshing in the liquid tank.

[0090] In this embodiment, by comparing the difference between the first and second wall wave heights with a set threshold, the normal sloshing form can be determined. The direction of movement of the structure is controlled based on the positive or negative difference, enhancing the targeted control. When the difference is greater than 0, the structure moves toward the first wall detection unit, effectively suppressing the relatively strong liquid fluctuations on that side; the same applies when the difference is less than 0. This method can reduce the impact of liquid on the wall, improve the stability of the tank, avoid structural damage caused by excessive liquid sloshing, and ensure the safe and stable operation of the tank under various operating conditions.

[0091] In one embodiment, Figure 4 As shown, before controlling the structure to move toward the first wall detection unit with a target motion amplitude, the following steps are included:

[0092] Step 401: detecting a first incident wave height, a first reflected wave height, and a first transmitted wave height using a first middle detection unit disposed between the structure and the first wall detection unit;

[0093] A first central detection unit is provided between the structure and the first wall detection unit. The first central detection unit can detect multiple wave heights, including a first incident wave height, a first reflected wave height, and a first transmitted wave height. The first incident wave height may refer to the height of an incident wave propagating from another location between the structure and the first wall detection unit; the first reflected wave height may refer to the height of a reflected wave at the first central detection unit when the structure reflects part of the wave energy upon reaching the structure; and the first transmitted wave height may refer to the height of a wave propagating through the structure toward the first wall detection unit at the first central detection unit.

[0094] Step 402: Determine the first target radiation wave height at the first middle detection unit based on the first wall wave height, the first incident wave height, the first reflected wave height, and the first transmitted wave height. Substitute the first target radiation wave height into the mapping relationship to obtain the target motion amplitude. The first target radiation wave height satisfies the following relationship:

[0095] ;

[0096] Where, represents the first wall wave height, represents the height of the first incident wave, represents the height of the first reflected wave, Indicates the radiation wave height of the first target, Represents the first transmitted wave height;

[0097] It should be noted that the first wall wave height It can reflect the degree of liquid fluctuation on the first wall of the tank; the height of the first incident wave It can represent the height of the incident wave propagating from the outside to the space between the structure and the first wall detection unit; the height of the first reflected wave It can reflect the wave height reflected when the wave reaches the structure; and the first transmitted wave height It can express the height of the wave that propagates through the structure toward the first wall detection unit. Calculate the first target radiation wave height .

[0098] Furthermore, the calculated first target radiation wave height Substitute the mapping relationship established before In the process, by radiating the first target wave height Substituting this mapping relationship and using the mathematical relationship in the mapping relationship, the corresponding first target motion amplitude can be calculated x bl .

[0099] In one embodiment, Figure 5 As shown, before controlling the structure to move toward the second wall detection unit with a target motion amplitude, the following steps are included:

[0100] Step 501: Detecting a second incident wave height, a second reflected wave height, and a second transmitted wave height using a second middle detection unit disposed between the structure and the second wall detection unit;

[0101] A second central detection unit is provided between the structure and the second wall detection unit. The second central detection unit can detect multiple wave heights, including a second incident wave height, a second reflected wave height, and a second transmitted wave height. The second incident wave height may refer to the height of an incident wave propagating from another location between the structure and the second wall detection unit; the second reflected wave height may refer to the height of a reflected wave at the second central detection unit when the structure reflects part of the wave energy upon reaching the structure; and the second transmitted wave height may refer to the height of a wave propagating through the structure toward the second wall detection unit at the second central detection unit.

[0102] Step 502: Determine the second target radiation wave height at the second middle detection unit based on the second wall wave height, the second incident wave height, the second reflected wave height, and the second transmitted wave height. Substitute the second target radiation wave height into the mapping relationship to obtain the target motion amplitude. The second target radiation wave height satisfies the following relationship:

[0103] ;

[0104] Where, represents the second wall wave height, represents the height of the second incident wave, represents the height of the second reflected wave, Indicates the second target radiation wave height, Represents the second transmitted wave height.

[0105] It should be noted that the second wall wave height It can reflect the degree of liquid fluctuation on the second wall of the liquid tank; the second incident wave height It can represent the height of the incident wave propagating from the outside to the space between the structure and the second wall detection unit; the height of the second reflected wave It can reflect the wave height reflected when the wave reaches the structure; and the second transmitted wave height It can express the height of the wave that propagates through the structure toward the second wall detection unit. Calculate the corresponding second target radiation wave height .

[0106] Furthermore, the calculated second target radiation wave height Substitute the mapping relationship established before In the process, the second target radiation wave height Substituting into the mapping relationship, using the mathematical relationship in the mapping relationship, the corresponding second target motion amplitude can be calculated x br .

[0107] In this embodiment, the method acquires wave height data at different locations by respectively setting first and second middle detection units between the structure and the wall detection unit. Before controlling the structure to move toward the two side walls, the target radiation wave height is determined based on the wave height data from each detection unit in combination with a specific relationship, and the target motion amplitude is substituted into the mapping relationship. This method improves the accuracy and effectiveness of control and can specifically adjust the motion amplitude of the structure according to the actual wave conditions of different wall surfaces, thereby suppressing liquid sloshing, reducing the impact of liquid on the wall, enhancing the stability of the liquid tank, reducing the safety risks caused by liquid sloshing, and ensuring the safe and reliable operation of the liquid tank under complex working conditions.

[0108] In one embodiment, the Calculate the target motion amplitude x b The first target motion amplitude can be substituted into the formula x bl and the second target motion amplitude x br Calculate the target motion amplitude x b .

[0109] In one embodiment, the sloshing form includes a Faraday wave sloshing form, and optimizing the target motion amplitude according to the sloshing form of the liquid tank includes:

[0110] If the difference is within the set threshold range, the sloshing form is determined to be Faraday wave sloshing; the weights of the target motion amplitudes of the structure in the two relative directions are determined according to the ratio of the first wall wave height to the second wall wave height.

[0111] Specifically, when the difference between the calculated first wall wave height and the second wall wave height is within a set threshold range, the sloshing form of the liquid in the liquid tank is determined to be a Faraday wave sloshing form. In the case of the Faraday wave sloshing form, the weights of the target motion amplitudes of the structure in two relative directions can be determined based on the ratio of the first wall wave height to the second wall wave height. It should be noted that in the Faraday wave sloshing form, the fluctuation of the liquid in the liquid tank has specific laws and characteristics, and the ratio of the first wall wave height to the second wall wave height can reflect the relative strength of the liquid fluctuations in the two directions. By using the ratio of the first wall wave height to the second wall wave height, the weights of the structure's motion amplitudes in the two directions can be more accurately allocated, so that the movement of the structure can better adapt to the fluctuation of the liquid under the Faraday wave sloshing form.

[0112] For example, if the ratio of the first wall wave height to the second wall wave height is large, it means that the liquid fluctuations in the direction corresponding to the first wall are relatively stronger. When determining the target motion amplitude, the amplitude of the structure's movement in this direction can be given a greater weight, thereby more effectively suppressing the stronger liquid fluctuations in this direction; conversely, if the ratio is small, the weight distribution can be adjusted accordingly to achieve a better sloshing suppression effect, ensuring that the liquid tank can remain stable even under Faraday wave sloshing, and reducing the impact of liquid sloshing on the liquid tank structure.

[0113] In this embodiment, after identifying the Faraday wave sloshing pattern, the method determines the target motion amplitude weight based on the ratio of the first and second wall wave heights. By determining this specific sloshing pattern, control can be implemented based on the unique patterns of liquid fluctuations within the tank. The wave height ratio reflects the relative strength of the liquid fluctuations on both sides, and weights are assigned accordingly to rationally adjust the motion amplitude of the structure in both directions. This not only enhances the targeted control of the structure's motion, but also effectively suppresses liquid sloshing, reduces uneven impact on the tank walls, improves the overall stability of the tank, reduces the risk of structural damage caused by special sloshing patterns, and ensures smooth and safe operation of the tank under complex operating conditions.

[0114] In one embodiment, Figure 6 As shown, the weights of the target motion amplitudes of the structure in two relative directions are determined according to the ratio of the first wall wave height to the second wall wave height, including the following steps:

[0115] Step 601: Determine the ratio of the first wall wave height to the second wall wave height. The ratio satisfies the following relationship:

[0116] ;

[0117] Where, α Represents the ratio, represents the first wall wave height, Represents the second wall wave height;

[0118] α It represents the ratio of the first wall wave height to the second wall wave height, and its relationship is: .in, Indicates the first wall wave height, which can reflect the degree of liquid fluctuation on the first wall of the tank; It indicates the second wall wave height, which can reflect the liquid fluctuation on the second wall of the liquid tank.

[0119] By calculating the ratio of these two wall wave heights, the magnitude relationship of the first wall wave height relative to the second wall wave height can be intuitively obtained. The ratio of the first wall wave height to the second wall wave height can reflect the relative strength of the liquid fluctuations in the two wall directions. For example, if the ratio of the first wall wave height to the second wall wave height is large, it means that the first wall wave height is larger than the second wall wave height, that is, the liquid fluctuations in the first wall direction are stronger, then when determining the target motion amplitude weight, it will tend to give a greater weight to the amplitude of the structure's movement in the first wall direction, so as to more effectively suppress the stronger liquid fluctuations in this direction; on the contrary, if the ratio of the first wall wave height to the second wall wave height is small, the weight distribution is adjusted accordingly according to the specific value, so that the movement of the structure can better adapt to the fluctuations of the liquid in the liquid tank, and achieve a better sloshing suppression effect.

[0120] Step 602: Detecting the first incident wave height, the first reflected wave height, and the first transmitted wave height based on the first middle detection unit disposed between the structure and the first wall detection unit; determining the first target radiation wave height at the first middle detection unit according to the first wall wave height, the first incident wave height, the first reflected wave height, and the first transmitted wave height; substituting the first target radiation wave height into the mapping relationship to obtain a first target motion amplitude of the structure toward the first wall detection unit;

[0121] The first incident wave height, the first reflected wave height, and the first transmitted wave height are detected using a first central detection unit positioned between the structure and the first wall detection unit. Based on the first wall wave height, the first incident wave height, the first reflected wave height, and the first transmitted wave height, a relationship is calculated to determine the first target radiation wave height at the first central detection unit. Substituting the first target radiation wave height into the previously established mapping relationship, and utilizing the inherent mathematical and physical connections within the mapping relationship, the first target motion amplitude of the structure toward the first wall detection unit can be inferred.

[0122] Step 603: Detecting the second incident wave height, the second reflected wave height, and the second transmitted wave height based on the second middle detection unit disposed between the structure and the second wall detection unit; determining the second target radiation wave height at the second middle detection unit according to the second wall wave height, the second incident wave height, the second reflected wave height, and the second transmitted wave height; substituting the second target radiation wave height into the mapping relationship to obtain the second target motion amplitude of the structure toward the second wall detection unit;

[0123] The second incident wave height, the second reflected wave height, and the second transmitted wave height are detected using a second central detection unit positioned between the structure and the second wall detection unit. Based on the second wall wave height, the second incident wave height, the second reflected wave height, and the second transmitted wave height, a relationship is calculated to determine the second target radiation wave height at the second central detection unit. Substituting the second target radiation wave height into the previously established mapping relationship, and utilizing the inherent mathematical and physical connections within the mapping relationship, the second target motion amplitude of the structure toward the second wall detection unit can be inferred.

[0124] Step 604: Allocate weights of the first target motion amplitude and the second target motion amplitude according to the ratio to obtain a target motion amplitude. The target motion amplitude satisfies the following relationship:

[0125] ;

[0126] Where, represents the target motion amplitude, represents the first target motion amplitude, Indicates the second target motion amplitude.

[0127] The weights of the first target motion amplitude and the second target motion amplitude are allocated based on the ratio of the determined first wall wave height to the second wall wave height, thereby obtaining the target motion amplitude. The relationship is: . represents the first target motion amplitude; Indicates the second target motion amplitude.

[0128] According to this relationship, when When it is larger, adjust α The size makes The weight is reduced, the target motion amplitude tends to be balanced, and the sloshing of the liquid in the tank is suppressed; on the contrary, when When it is larger, adjust α The size makes The weight of is reduced, so that the target motion amplitude tends to be balanced and the sloshing of liquid in the tank is suppressed.

[0129] In this embodiment, by determining the weight based on the wave height ratio and then obtaining the target motion amplitude, it is possible to achieve fine-grained control of the movement of the structure. Detailed wave data is obtained using the first and second middle detection units, and the target radiation wave height and target motion amplitude on both sides are calculated respectively. Weights are allocated based on the ratio of the first and second wall wave heights, so that the motion amplitude of the structure in two directions can be dynamically adjusted according to the actual liquid fluctuation conditions. When the wall wave height on one side is relatively high, the target motion amplitude in the corresponding direction has a greater weight in the final target motion amplitude, thereby enhancing the ability to suppress liquid sloshing in the form of Faraday waves, reducing the impact of liquid on the tank wall, improving the stability of the tank, and ensuring the safe and reliable operation of the tank under complex working conditions.

[0130] In one embodiment, the process of determining wave data includes:

[0131] The waves passing through the middle detection unit are analyzed based on the Goda two-point method to obtain the incident wave height and the reflected wave height.

[0132] When determining wave data, a specific method is used: the Goda two-point method, which analyzes waves passing through the central detection unit. This method is a commonly used analysis method in wave research. Two measurement points are set at specific locations within the central detection unit, and the wave data measured at these two points is used for calculation and analysis.

[0133] Specifically, this method can extract useful information from complex wave motions, and then accurately obtain the incident wave height and the reflected wave height. The incident wave height refers to the height of the wave that propagates from the outside into the middle detection unit area, reflecting the initial impact of the external wave on the liquid fluctuation in the liquid tank; the reflected wave height is the height of the wave that is reflected back after encountering a structure or other obstacle, reflecting the reflection effect of the structure on the wave. The precise acquisition of these two wave heights through the Goda two-point method can provide an important data basis for the subsequent analysis and control of liquid sloshing in the liquid tank, better understand the physical processes of wave propagation and reflection in the liquid tank, and thus more effectively formulate corresponding control strategies to suppress liquid sloshing, ensure the stable operation and safety of the liquid tank, and improve the performance of the liquid tank under different working conditions.
