[0002] As an important carrier for storing liquid substances, liquid tanks are of great significance for the storage and transportation of liquid fuels such as petroleum and liquefied natural gas or other liquid substances, and are widely used in fields such as aerospace and ocean engineering. The liquid in the liquid tank will generate a liquid motion phenomenon under the action of external excitation, which is also called liquid sloshing. The force generated by the sloshing liquid acting on the liquid tank wall will affect the liquid tank structure, so it is necessary to limit the sloshing liquid.

[0003] In the related art, the way to suppress liquid sloshing is to set a damping mechanism in the liquid tank, which includes a fixed damping mechanism and a passive floating damping mechanism. The design and use cost of the fixed damping mechanism is large, and it cannot be quickly adjusted for different liquid depths. The passive floating damping mechanism will move with the liquid motion, and its ability to eliminate liquid sloshing is limited. Summary of the Invention

Detailed Embodiments

[0017] In order to enable those skilled in the art to better understand the solution of the present application, the technical solutions in the specific embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present application.

[0018] The present application provides a method for suppressing liquid sloshing, as Figure 1 shown, the method includes the following steps: Step 101: Determine the immersion depth of the structure in the liquid. A middle detection unit is arranged between the structure and the side wall of the liquid tank. When the structure moves in the liquid with an initial motion amplitude, based on the middle detection unit, detect the initial radiation waves generated by the movement of the structure.

[0019] A structure is arranged in the liquid tank. The immersion depth can reflect the specific depth of the structure immersed in the liquid, and can be determined by a sensor or any other means capable of determining its depth. A middle 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 middle detection unit will detect the initial radiation waves generated by the movement of the structure. It should be noted that the structure can be a functional device for suppressing liquid sloshing in the liquid tank, such as a damping structure. Among them, the middle detection unit, as a key measurement component, is located between the structure and the side wall of the liquid tank, and the main function of the middle detection unit can be to monitor the fluctuation of the liquid.

[0020] Furthermore, according to the principle of fluid mechanics, the movement of the structure in the liquid will cause disturbance to the liquid, thereby generating radiation waves. The middle detection unit can obtain key physical quantities of these initial radiation waves through detection, such as wave height, wavelength, frequency and other information.

[0021] Exemplarily, 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 middle detection unit will measure the initial radiation waves generated by its movement in the oil, and adjust parameters such as the motion amplitude and frequency of the damping structure according to the obtained data.

[0022] Step 102: Based on the initial radiation waves, determine the preset distance between the structure and the middle detection unit and the initial radiation wave height at the middle detection unit, and establish a mapping relationship among the immersion depth, the preset distance, the initial radiation wave height, and the initial motion amplitude; Based on the detected initial radiation waves, determine multiple important parameters, including the preset distance between the structure and the middle detection unit and the initial radiation wave height at the middle detection unit. The preset distance can be a preset physical quantity, and its value can affect the characteristics of the waves generated by the movement of the structure when transmitted to the middle detection unit. The initial radiation wave height can reflect the energy magnitude of the initial radiation waves at the position of the middle detection unit.

[0023] Furthermore, establish a mapping relationship among the immersion depth, the preset distance, the initial radiation wave height, and the initial motion amplitude. Among them, this mapping relationship can show the internal connection among each parameter, and can be analyzed by calculating a large amount of experimental data through a machine learning system to summarize how different parameters affect each other. The obtained mapping relationship is and , where the immersion depth is d, the initial motion amplitude is xb, the preset distance between the middle detection unit and the structure is L, and the initial radiation wave height is η t . It should be noted that when the middle detection unit is arranged 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 determined by the middle detection unit on the left side of the structure η l , and determined by the middle detection unit on the right side of the structure η r , so as to determine the above mapping relationship.

[0024] In some examples, when considering the time delay processing phenomenon, η l and η r are the values at the moment t' after adding the motor control response time / numerical calculation adjustment time △t to the current moment t.

[0025] It should be noted that the establishment of the mapping relationship can provide a basis for subsequent operations. According to different immersion depths, preset distances and other conditions, the corresponding radiation wave height and motion amplitude can be predicted, or the immersion depth and preset distance of the structure can be adjusted according to the expected radiation wave height and motion amplitude.

[0026] Step 103: In the case of external excitation in the liquid tank, based on the wave data detected by the middle detection unit, the wave data includes the incident wave height from the side wall to the middle detection unit, the reflected wave height reflected by the structure to the middle detection unit, and the transmitted wave height transmitted through the structure to the middle detection unit; The external excitation may refer to the influence of some factors 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. The external excitation may cause complex wave phenomena in the liquid in the liquid tank.

[0027] Furthermore, based on the middle detection unit, the wave data under the external excitation is detected. The detected wave data includes the incident wave height from the side wall to the middle detection unit; the reflected wave height reflected by the structure to the middle detection unit, and the transmitted wave height transmitted through the structure to the middle detection unit.

[0028] Among them, the incident wave height in the direction 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. Its height is related to the intensity of the external excitation and the characteristics of the liquid. The reflected wave height reflected by the structure towards the middle detection unit can reflect the reflection ability of the structure to the incident wave, and its magnitude is affected by the physical characteristics of the structure and the incident wave. The transmitted wave height transmitted through the structure towards the middle detection unit can reflect the wave energy that continues to propagate towards the middle detection unit after the incident wave passes through the structure, and its height is affected by the permeability of the structure and its attenuation ability to waves.

[0029] By detecting the wave data, the wave propagation and energy distribution in different directions inside the liquid tank under external excitation can be grasped, providing a data basis for subsequent analysis and control. Furthermore, it helps to evaluate the performance of the structure under different external excitations, so as to adjust the parameters of the structure or take other control measures.

[0030] 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 motion of the structure according to the target motion amplitude to make the wall wave height at the side wall within the target range.

[0031] Based on the wave data obtained in Step 103, that is, the incident wave height in the direction from the side wall to the middle detection unit, the reflected wave height reflected by the structure towards the middle detection unit, and the transmitted wave height transmitted through the structure towards the middle detection unit, determine the target radiation wave height at the middle detection unit.

[0032] Based on this target radiation wave height and the mapping relationship between the immersion depth, preset distance, radiation wave height, and motion amplitude established in Step 102, determine the target motion amplitude of the structure. The mapping relationship can determine the internal connection between each parameter. Therefore, when the target radiation wave height is known, the corresponding target motion amplitude of the structure can be inversely deduced through the mapping relationship. Further, control the motion of the structure based on the calculated target motion amplitude. By adjusting the motion state of the structure, the wave motion of the liquid is affected, so that the wall wave height at the side wall is within the target range.

[0033] It should be noted that the wall wave height at the side wall being within the target range can ensure that the liquid fluctuation inside the liquid tank will not cause excessive pressure and impact on the side wall of the liquid tank, avoiding problems such as damage to the liquid tank structure and liquid leakage that may be caused by excessive liquid sloshing.

[0034] In this embodiment, the method can accurately detect the initial radiation waves generated by the movement of the structure by arranging a structure and a middle detection unit in the liquid tank, and then determine the preset distance between the structure and the middle detection unit and the initial radiation wave height, and construct the mapping relationship between the above parameters and the initial movement amplitude. When the liquid tank is externally excited, the middle detection unit can effectively detect key wave data such as the incident wave height, the reflected wave height, and the transmitted wave height of the waves, so as to accurately determine the target radiation wave height at the middle detection unit, determine the target movement amplitude of the structure according to the mapping relationship, and control the movement of the structure according to 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 wave climbing on the side wall, 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.

[0035] In one embodiment, the interior of the liquid tank is as Figure 2 shown, where 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 first incident wave height, represents the first reflected wave height, represents the first target radiation wave height, represents the first transmitted wave height, represents the second wall wave height, represents the second incident wave height, represents the second reflected wave height, represents the second target radiation wave height, represents the second transmitted wave height. The first preset distance is L 1 and the second preset distance is L 2 .

[0036] In one embodiment, as Figure 3 shown, wall detection units are arranged at two opposite side walls of the liquid tank, and the middle detection unit is arranged between the structure and the wall detection unit. Before controlling the movement of the structure according to the target movement amplitude, the method further includes the following steps: Step 301: Detect the first wall wave height based on the first wall detection unit on one side of the structure, and detect the second wall wave height based on the second wall detection unit on the other side of the structure; Detect the first wall wave height through the first wall detection unit on one side of the structure. The first wall wave height can reflect the influence of the liquid fluctuation on this side wall of the liquid tank. Similarly, the second wall wave height can be detected by using the second wall detection unit on the other side of the structure, and the second wall wave height can reflect the liquid fluctuation condition of the other side wall of the liquid tank.

[0037] By detecting the wave height of the first wall surface and the wave height of the second wall surface, the liquid fluctuation state borne by the two side wall surfaces of the liquid tank can be grasped, providing more accurate and comprehensive information for the subsequent motion control of the structure.

[0038] Step 302: In the case that there is an external excitation in the liquid tank, determine the sloshing form of the liquid in the liquid tank according to the difference between the wave height of the first wall surface and the wave height of the second wall surface, and optimize the target motion amplitude according to the sloshing form.

[0039] Determine the sloshing form of the liquid in the liquid tank according to the difference between the wave height of the first wall surface detected by the first wall surface detection unit and the wave height of the second wall surface detected by the second wall surface detection unit. Among them, different sloshing forms can cause different differences in the wave heights of the two side wall surfaces. By analyzing this difference, the flow and sloshing laws of the liquid in the liquid tank can be obtained, such as whether the liquid is in normal sloshing, special waveform sloshing, or symmetric sloshing or asymmetric sloshing and a certain specific periodic sloshing mode, etc.

[0040] Optimize the target motion amplitude according to the determined sloshing form. It should be noted that different sloshing forms have different requirements for the motion response of the structure. For some sloshing forms, it may be necessary to increase the target motion amplitude to better suppress sloshing, while for other sloshing forms, it may be necessary to decrease the target motion amplitude or adjust other parameters such as its motion frequency and direction. In this way, adjusting the motion amplitude of the structure to the state most suitable for the current sloshing form can more effectively suppress the sloshing of the liquid and ensure that the liquid in the liquid tank remains relatively stable under various external excitations.

[0041] In this embodiment, this method has multiple technical advantages by setting wall surface detection units on the relatively two side walls of the liquid tank and setting a middle detection unit between the structure and the wall surface detection units. Before controlling the motion of the structure, detect the wave heights of the first and second wall surfaces, and determine the sloshing form based on the difference between the two, and then optimize the target motion amplitude. This makes the control of the structure motion more in line with the actual sloshing situation of the liquid in the liquid tank, enhancing the pertinence and effectiveness of suppressing liquid sloshing. Further, the sloshing form judgment helps to adjust the motion amplitude of the structure, reduce the impact of the liquid on the wall surface, and improve the structural stability of the liquid tank.

[0042] In one embodiment, the sloshing form includes a normal sloshing form. Optimizing the target motion amplitude according to the sloshing form of the liquid tank includes: If the difference is outside the set threshold range, it is determined that the sloshing form is the conventional sloshing form. When the difference is greater than 0, the structure is controlled to move in the direction of the first wall detection unit with the 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 the target motion amplitude.

[0043] Specifically, when the difference obtained by calculating the wave height of the first wall and the wave height of the second wall is outside the set threshold range, it can be determined that the sloshing form of the liquid in the liquid tank at this time is the conventional sloshing form. In this conventional sloshing form, the movement direction of the structure can be controlled according to the positive or negative of the difference.

[0044] If the difference is greater than 0, it means that the wave height of the first wall is higher than that of the second wall, and the liquid is more inclined to fluctuate towards the side where the first wall detection unit is located. The structure can be controlled to move in the direction of the first wall detection unit with the target motion amplitude. The purpose is to suppress the fluctuation on this side through the movement of the structure in the direction of the first wall detection unit to balance the liquid sloshing in the liquid tank.

[0045] If the difference is less than 0, it means that the wave height of the second wall is higher than that of the first wall, and the liquid is more inclined to fluctuate towards the side where the second wall detection unit is located. The structure can be controlled to move in the direction of the second wall detection unit with the target motion amplitude. The purpose is to suppress the fluctuation on this side through the movement of the structure in the direction of the second wall detection unit to balance the liquid sloshing in the liquid tank.

[0046] In this embodiment, by comparing the difference between the wave heights of the first and second walls with the set threshold, the conventional sloshing form can be judged. The movement direction of the structure is controlled according to the positive or negative of the difference, enhancing the pertinence of the control. When the difference is greater than 0, the structure moves in the direction of the first wall detection unit, which can effectively suppress the relatively strong liquid fluctuation on this side; the same is true when the difference is less than 0. This method can reduce the impact of the liquid on the wall, improve the stability of the liquid tank, avoid structural damage caused by excessive liquid sloshing, and ensure the safe and stable operation of the liquid tank under various working conditions.

[0047] In one embodiment, as Figure 4 shown, before controlling the structure to move in the direction of the first wall detection unit with the target motion amplitude, the following steps are included: Step 401: Detect the first incident wave height, the first reflected wave height, and the first transmitted wave height based on the first middle detection unit arranged between the structure and the first wall detection unit; A first middle detection unit is arranged between the structure and the first wall surface detection unit. The first middle detection unit can detect various wave heights of waves, including the first incident wave height, the first reflected wave height, and the first transmitted wave height. Among them, the first incident wave height may refer to the height of the incident wave propagating from other positions between the structure and the first wall surface detection unit; the first reflected wave height may be the wave height of the reflected wave at the first middle detection unit when the wave reaches the structure and the structure reflects part of the wave energy back; the first transmitted wave height may be the wave height of the wave propagating through the structure towards the first wall surface detection unit at the first middle detection unit.

[0048] Step 402: Determine the first target radiation wave height at the first middle detection unit according to the first wall surface wave height, the first incident wave height, the first reflected wave height, and the first transmitted wave height, and 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 relational expression: ; In the formula, represents the first wall surface wave height, represents the first incident wave height, represents the first reflected wave height, represents the first target radiation wave height, represents the first transmitted wave height; It should be noted that the first wall surface wave height can reflect the degree of liquid fluctuation on the first wall surface of the liquid tank; the first incident wave height can represent the height of the incident wave propagating from the outside between the structure and the first wall surface detection unit; the first reflected wave height can reflect the wave height of the wave reflected back when the wave reaches the structure; and the first transmitted wave height can represent the height of the wave propagating through the structure towards the first wall surface detection unit. The first target radiation wave height can be calculated through the relational expression .

[0049] Furthermore, substitute the calculated first target radiation wave height into the previously established mapping relationship . By substituting the first target radiation wave height into this mapping relationship and using the mathematical relationship in the mapping relationship, the corresponding first target motion amplitude x bl can be calculated.

[0050] In one embodiment, as Figure 5As shown, before controlling the structure to move towards the second wall detection unit with a target motion amplitude, the following steps are included: Step 501: Detect the second incident wave height, the second reflected wave height, and the second transmitted wave height based on the second middle detection unit arranged between the structure and the second wall detection unit; A second middle detection unit is arranged between the structure and the second wall detection unit. This second middle detection unit can detect various wave heights, including the second incident wave height, the second reflected wave height, and the second transmitted wave height. Among them, the second incident wave height can refer to the height of the incident wave propagating from other positions towards the area between the structure and the second wall detection unit; the second reflected wave height can be the wave height of the reflected wave at the second middle detection unit when the wave reaches the structure and the structure reflects part of the wave energy back; the second transmitted wave height can be the wave height of the wave propagating through the structure towards the second wall detection unit at the second middle detection unit.

[0051] Step 502: Determine 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, and 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 relational expression: ; In the formula, represents the second wall wave height, represents the second incident wave height, represents the second reflected wave height, represents the second target radiation wave height, represents the second transmitted wave height.

[0052] It should be noted that the second wall wave height can reflect the degree of liquid fluctuation on the second wall of the liquid tank; the second incident wave height can represent the height of the incident wave propagating from the outside towards the area between the structure and the second wall detection unit; the second reflected wave height can reflect the wave height of the wave reflected back when the wave reaches the structure; and the second transmitted wave height can represent the height of the wave propagating through the structure towards the second wall detection unit. The corresponding second target radiation wave height can be calculated through the relational expression .

[0053] Furthermore, substitute the calculated second target radiation wave height into the previously established mapping relationship By radiating the second target 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 .

[0054] In this embodiment, the method obtains wave height data at different positions by respectively setting the 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 of each detection unit in combination with a specific relationship, and the target motion amplitude is obtained by substituting 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 walls, 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.

[0055] In one embodiment, according to 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 .

[0056] In one embodiment, the sloshing form includes a Faraday wave sloshing form, and the target motion amplitude is optimized according to the sloshing form of the liquid tank, including: If the difference is within the set threshold range, the sloshing form is determined to be the Faraday wave sloshing form; and 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.

[0057] Specifically, when the difference obtained by calculating the first wall wave height and the second wall wave height is within a set threshold range, it is determined that the sloshing form of the liquid in the liquid tank is the Faraday wave sloshing form. In the case of the Faraday wave sloshing form, the weights of the target motion amplitudes in two directions relative to the structure 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 rules 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 fluctuation in two directions. By the ratio of the first wall wave height to the second wall wave height, the weights of the motion amplitudes of the structure in two directions can be more accurately allocated, so that the motion of the structure can better adapt to the liquid fluctuation under the Faraday wave sloshing form.

[0058] Exemplarily, if the ratio of the first wall wave height to the second wall wave height is large, it means that the liquid fluctuates relatively stronger in the direction corresponding to the first wall. When determining the target motion amplitude, a greater weight can be given to the amplitude of the structure moving in this direction, so as to more effectively suppress the stronger liquid fluctuation in this direction; on the contrary, if the ratio is small, the weight distribution can be adjusted accordingly to achieve a better sloshing suppression effect, ensure the stability of the liquid tank under the Faraday wave sloshing form, and reduce the influence of liquid sloshing on the structure of the liquid tank.

[0059] In this embodiment, after identifying the Faraday wave sloshing form, the method determines the target motion amplitude weights according to the ratio of the first and second wall wave heights. By judging this specific sloshing form, it can be regulated according to the unique law of the liquid fluctuation in the liquid tank. The wave height ratio reflects the relative strength of the liquid fluctuation on both sides. Based on this, the weights are allocated to reasonably allocate the motion amplitudes of the structure in two directions. It not only enhances the pertinence of the motion control of the structure, but also can efficiently suppress the liquid sloshing, reduce the unbalanced impact on the liquid tank wall, improve the overall stability of the liquid tank, reduce the risk of structural damage caused by the special sloshing form, and ensure the stable and safe operation of the liquid tank under complex working conditions.

[0060] In one embodiment, as Figure 6 shown, determining the weights of the target motion amplitudes in two directions relative to the structure according to the ratio of the first wall wave height to the second wall wave height includes the following steps: Step 601: Determine the ratio of the first wall wave height to the second wall wave height, and the ratio satisfies the following relationship: ; In the formula, α represents the ratio, represents the first wall wave height, represents the second wall wave height; αDenotes the ratio of the first wall wave height to the second wall wave height, and the relational expression is . Among them, Denotes the first wall wave height, which can reflect the degree of liquid fluctuation received by the first wall of the liquid tank; Denotes the second wall wave height, which can reflect the liquid fluctuation condition of the second wall of the liquid tank.

[0061] By calculating the ratio of these two wall wave heights, the size 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 liquid fluctuations in the two wall directions. Exemplarily, 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 relatively larger than the second wall wave height, that is, the liquid fluctuation in the direction of the first wall is stronger. Then, when determining the target motion amplitude weight, it will tend to assign a larger weight to the amplitude of the structure moving in the direction of the first wall, so as to more effectively suppress the stronger liquid fluctuation in this direction; conversely, if the ratio of the first wall wave height to the second wall wave height is small, the weight distribution will be adjusted accordingly according to the specific value, so that the motion of the structure can better adapt to the liquid fluctuation condition in the liquid tank and achieve a better sloshing suppression effect.

[0062] Step 602: Based on the first middle detection unit disposed between the structure and the first wall detection unit, detect the first incident wave height, the first reflected wave height, and the first transmitted wave height. Determine 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, and substitute the first target radiation wave height into the mapping relationship to obtain the first target motion amplitude of the structure in the direction of the first wall detection unit; Use the first middle detection unit disposed between the structure and the first wall detection unit to detect the first incident wave height, the first reflected wave height, and the first transmitted wave height. Based on the first wall wave height, the first incident wave height, the first reflected wave height, and the first transmitted wave height, through relational expression calculation, the first target radiation wave height at the first middle detection unit can be determined. Substitute the first target radiation wave height into the previously established mapping relationship. By substituting the first target radiation wave height into this mapping relationship and using the inherent mathematical and physical correlations in the mapping relationship, the first target motion amplitude of the structure in the direction of the first wall detection unit can be inversely deduced.

[0063] Step 603: Detect 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 surface detection unit. Determine the second target radiation wave height at the second middle detection unit according to the second wall surface 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 second target motion amplitude of the structure in the direction of the second wall surface detection unit. The second middle detection unit disposed between the structure and the second wall surface detection unit is used to detect the second incident wave height, the second reflected wave height, and the second transmitted wave height. Based on the second wall surface wave height, the second incident wave height, the second reflected wave height, and the second transmitted wave height, through relational calculation, the second target radiation wave height at the second middle detection unit can be determined. Substitute the second target radiation wave height into the previously established mapping relationship. By substituting the second target radiation wave height into this mapping relationship and utilizing the internal mathematical and physical correlations of the mapping relationship, the second target motion amplitude of the structure in the direction of the second wall surface detection unit can be inversely deduced.

[0064] Step 604: Allocate the weights of the first target motion amplitude and the second target motion amplitude according to the ratio to obtain the target motion amplitude, and the target motion amplitude satisfies the following relational expression: ; In the formula, represents the target motion amplitude, represents the first target motion amplitude, represents the second target motion amplitude.

[0065] Based on the ratio of the determined first wall surface wave height and the second wall surface wave height, allocate the weights of the first target motion amplitude and the second target motion amplitude to obtain the target motion amplitude, and the relational expression is . represents the first target motion amplitude; represents the second target motion amplitude.

[0066] Through this relational expression, when is relatively large, adjust α so that the weight is reduced, making the target motion amplitude tend to be balanced and suppressing the liquid sloshing in the liquid tank; conversely, when is relatively large, adjust α so that the weight is reduced, making the target motion amplitude tend to be balanced and suppressing the liquid sloshing in the liquid tank.

[0067] In this embodiment, the method of determining the weight based on the wave height ratio and then obtaining the target motion amplitude can achieve fine control of the motion of the structure. The first and second middle detection units are used to obtain detailed wave data, and the target radiation wave height and target motion amplitude on both sides are calculated respectively. The weights are allocated based on the ratio of the first and second wall wave heights, so that the motion amplitudes of the structure in two directions can be dynamically adjusted according to the actual situation of liquid fluctuations. When the wave height of a certain side wall is relatively high, the weight of the target motion amplitude in the corresponding direction in the final target motion amplitude is greater, enhancing the ability to suppress liquid sloshing in the form of Faraday waves, reducing the impact of the liquid on the liquid tank wall, improving the stability of the liquid tank, and ensuring the safe and reliable operation of the liquid tank under complex working conditions.

[0068] In one embodiment, in the process of determining the wave data, it includes: Analyze the waves passing through the middle detection unit based on the Goda two-point method to obtain the incident wave height and the reflected wave height.

[0069] When determining the wave data, a specific method will be adopted, that is, analyzing the waves passing through the middle detection unit based on the Goda two-point method. The Goda two-point method is a commonly used analysis method in the field of wave research. By setting two measurement points at specific positions in the middle detection unit, the wave data measured by these two points are used for calculation and analysis.

[0070] 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 waves propagating from the outside into the area of the middle detection unit, reflecting the initial impact of external waves on the liquid fluctuations in the liquid tank; the reflected wave height is the height of the waves reflected back after the waves encounter the structure or other obstacles, reflecting the reflection effect of the structure on the waves. By accurately obtaining these two wave heights through the Goda two-point method, it can provide an important data basis for the subsequent analysis and control of liquid sloshing in the liquid tank, better understand the physical processes such as 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.
