Description

[0002] Pipeline multi-field coupling resonance refers to the phenomenon that the vortex shedding frequency, branch pipe acoustic modal frequency and branch pipe natural frequency appear in the closed stagnant branch pipe area connected by the pipeline tee during transportation, that is, the pipeline has a flow-acoustic-solid three-field coupling resonance phenomenon.

[0003] Currently, one method for controlling pipeline resonance involves welding upstream of the main pipeline tee, but this method increases the flow resistance of the main pipeline. Another method involves adding an insert at the tee connection, but this increases the discharge resistance of the branch pipe and is prone to fatigue failure and fall-off, posing a threat to the safe operation of the pipeline system and resulting in poor pipeline resonance control effectiveness.

[0097] The multi-field coupling resonance of a pipeline refers to the phenomenon that the vortex shedding frequency, the branch sound mode frequency, and the branch self-vibration frequency are the same in the closed stagnant branch pipe area connected by the pipeline tee during the transportation process of the pipeline system, that is, the pipeline has a fluid-acoustic-solid three-field coupling resonance phenomenon.

[0098] Currently, a related method for pipeline resonance control is to perform surfacing welding upstream of the main pipeline tee, but this method increases the fluid resistance of the main pipeline; another related method is to add an internal insert at the connection of the pipeline tee, but this method increases the branch discharge resistance and is also prone to the phenomenon of shedding due to fatigue failure, posing a threat to the safe operation of the pipeline system and resulting in poor pipeline resonance control effect. Therefore, how to improve the effect of pipeline resonance control remains a difficult problem urgently to be solved in the industry.

[0099] Therefore, by using the coaxial projection method with the same variables, the vortex shedding frequency parameters, pipe acoustic modal frequency parameters, and pipe self-vibration frequency parameters from different sources can be subjected to fluid-structure-acoustic resonance tests to improve the effect of pipe resonance control. When the pipe resonance test data indicates the occurrence of fluid-structure-acoustic resonance between the main pipe and the branch pipe, fluid-structure-acoustic resonance control measures can be implemented on the pipe system. This can promptly implement control measures when it is detected that fluid-structure-acoustic resonance may occur between the main pipe and the branch pipe, avoiding the impact of fluid-structure-acoustic resonance and improving the effect of pipe control.

[0100] This application aims to solve at least one of the technical problems existing in the prior art. To this end, this application proposes a pipe multi-field coupling resonance control method, a pipe system, an electronic device, and a medium, which can improve the effect of pipe resonance control.

[0101] The following is a further description based on the accompanying drawings:

[0102] Referring to Figure 1 , which is applied to pipe resonance control of a pipe system. The pipe system includes a main pipe and a branch pipe. One end of the branch pipe is connected to the main pipe to form a tee structure at the pipe connection position between the branch pipe and the main pipe.

[0106] Step S104: When the pipe resonance test data indicates the occurrence of fluid-structure-acoustic resonance between the main pipe and the branch pipe, implement fluid-structure-acoustic resonance control measures on the pipe system.

[0107] The pipeline multi-field coupling resonance control method shown in steps S101 to S104 of the embodiments of the present application is applied to control pipeline resonance of a pipeline system. The pipeline system includes a main pipeline and a branch pipeline. One end of the branch pipeline is connected to the main pipeline to form a tee structure at the pipeline connection position between the branch pipeline and the main pipeline, and has at least the following beneficial effects: First, obtain the tee structure parameters corresponding to the tee structure and the main pipeline condition data corresponding to the main pipeline, and calculate the tee vortex shedding frequency parameters, pipeline acoustic mode frequency parameters, and pipeline self-vibration frequency parameters corresponding to the pipeline system based on the tee structure parameters and the main pipeline condition data, providing data support for subsequent pipeline resonance inspection; Second, perform fluid-structure-acoustic resonance inspection based on the tee vortex shedding frequency parameters, pipeline acoustic mode frequency parameters, and pipeline self-vibration frequency parameters to obtain pipeline resonance inspection data, which can detect whether there is a risk of fluid-structure-acoustic resonance in the pipeline system; Finally, when the pipeline resonance inspection data indicates that fluid-structure-acoustic resonance occurs between the main pipeline and the branch pipeline, perform fluid-structure-acoustic resonance control measures on the pipeline system, which can timely execute preventive measures for pipeline multi-field coupling resonance when it is detected that fluid-structure-acoustic resonance may occur between the main pipeline and the branch pipeline, so as to effectively adjust the operating state of the pipeline system and avoid the influence of fluid-structure-acoustic resonance. In this way, the effect of pipeline resonance control can be improved.

[0108] In step S101 of some embodiments, specifically, the tee structure refers to the tee part formed by the connection of the main pipeline and the branch pipeline in the pipeline system.

[0109] Specifically, the tee structure parameters include but are not limited to the geometric dimensions of the tee (such as the outer diameter of the main pipe, the inner diameter of the main pipe, the length of the main pipe, the thickness of the main pipe, the elastic modulus of the main pipe, the outer diameter of the branch pipe, the inner diameter of the branch pipe, the length of the branch pipe, the thickness of the branch pipe, and the elastic modulus of the branch pipe, etc.), the connection angle between the branch pipe and the main pipe, and the ratio of the diameter of the branch pipe to the diameter of the main pipe, etc.

[0110] Specifically, the branch pipe can be a closed stagnant branch pipe. Among them, the closed stagnant branch pipe is a non-flowing branch formed by physical isolation (such as valve closing) or structural enclosure (such as a blind plate), and the internal fluid of this branch pipe has no continuous exchange with the main pipeline and is in a stagnant state.

[0111] Specifically, the main pipeline condition data is time-series data, including but not limited to the operating data such as the fluid flow rate, pressure, and temperature of the main pipeline.

[0112] Referring to Figure 2 , in some embodiments, step S102 calculates the tee vortex shedding frequency parameters, pipeline acoustic mode frequency parameters, and pipeline self-vibration frequency parameters corresponding to the pipeline system based on the tee structure parameters and the main pipeline condition data, and may include, but are not limited to:

[0113] Step S201: Based on the tee structure parameters and the main pipeline operating conditions data, perform hydrodynamic calculations on the tee structure to obtain the tee vortex shedding frequency parameters;

[0114] Step S202: Based on the tee structure parameters and the main pipeline operating conditions data, perform acoustic vibration frequency calculations on the branch pipe to obtain the pipeline acoustic modal frequency parameters;

[0115] Step S203: Based on the tee structure parameters, perform pipeline natural vibration frequency calculations to obtain the pipeline natural vibration frequency parameters.

[0116] In step S201 of some embodiments, specifically, the tee vortex shedding frequency parameters refer to the vibration frequency parameters generated by the pipeline fluid due to vortex shedding at the tee structure.

[0117] Specifically, if the main pipeline operating conditions data is the main pipeline flow velocity and the tee structure parameter is the branch pipe inner diameter; then, based on the tee structure parameters and the main pipeline operating conditions data, perform hydrodynamic calculations on the tee structure to obtain the tee vortex shedding frequency parameters, including: calculating the main pipeline flow velocity, the branch pipe inner diameter, and the preset Strouhal number to obtain the tee vortex shedding frequency parameters.

[0118] Specifically, the main pipeline flow velocity refers to the flow velocity of the fluid in the main pipeline.

[0119] Specifically, the branch pipe inner diameter refers to the inner diameter of the branch pipe, which is used to affect the flow state of the fluid at the tee structure.

[0120] Specifically, the Strouhal number is a dimensionless number used to describe the vortex shedding frequency when the fluid flows in a geometric structure.

[0121] Specifically, the tee vortex shedding frequency parameters under different main pipeline flow rates can be determined by the following formula:

[0122]

[0123] Where, St represents the Strouhal number, f v represents the tee vortex shedding frequency parameters, d represents the branch pipe inner diameter, and u represents the main pipeline flow velocity.

[0124] In this embodiment, by performing hydrodynamic calculations on the tee structure to obtain the tee vortex shedding frequency parameters, it is possible to quickly predict the tee vortex shedding frequency parameters at the tee structure using the known main pipeline operating conditions data and tee structure parameters, providing data support for subsequent fluid-structure-acoustic resonance tests.

[0125] In step S202 of some embodiments, specifically, the pipeline acoustic modal frequency parameters refer to the standing wave frequencies formed by the air column or liquid column in the pipeline due to pressure fluctuations.

[0126] Specifically, if the main pipeline operating condition data is the main pipeline temperature and the tee structure parameter is the branch pipe length, then based on the tee structure parameter and the main pipeline operating condition data, the acoustic vibration frequency of the branch pipe is calculated to obtain the pipeline acoustic modal frequency parameter, including: obtaining the pipeline acoustic velocity based on the main pipeline temperature; performing a division operation on the pipeline acoustic velocity and the branch pipe length to obtain the pipeline acoustic modal frequency parameter.

[0127] Specifically, the main pipeline temperature refers to the temperature of the fluid in the main pipeline; the branch pipe length refers to the geometric length of the branch pipe.

[0128] Specifically, the pipeline acoustic velocity refers to the propagation velocity of sound waves in the fluid medium of the pipeline, which is affected by the fluid temperature.

[0129] Specifically, the pipeline acoustic velocity can be determined by calculating the main pipeline temperature and the water physical properties. Specifically, since both the bulk modulus of elasticity of water and the density of water change with temperature, the pipeline acoustic velocity can be determined by calculating the relationship between the bulk modulus of elasticity of water and the density of water.

[0130] Specifically, the pipeline acoustic velocity can be determined by the following formula:

[0131]

[0132] Where C represents the pipeline acoustic velocity, B represents the bulk modulus of elasticity of water, and ρ represents the density of water.

[0133] For example, if the fluid in the main pipeline is water and the temperature is 25°C. According to the physical property table of water, the density of water at 25°C is about 997 kg / m 3 , and the bulk modulus of elasticity is about 2.15×10 9 Pa. Substituting these parameters into the calculation formula of the pipeline acoustic velocity, the pipeline acoustic velocity can be calculated to be 1497 m / s.

[0134] Furthermore, the pipeline acoustic modal frequency parameter corresponding to different main pipeline temperatures can be determined by the following formula:

[0135]

[0136] Where f s represents the first-order pipeline acoustic modal frequency parameter, λ represents the wavelength of sound waves, c represents the pipeline acoustic velocity, and h represents the branch pipe length.

[0137] In this embodiment, based on the tee structure parameter and the main pipeline operating condition data, the acoustic vibration frequency of the branch pipe is calculated to obtain the pipeline acoustic modal frequency parameter, which can accurately predict the acoustic vibration characteristics of the tee structure and provide data support for subsequent fluid-acoustic-solid resonance tests.

[0138] Step S203 of some embodiments. Specifically, the pipe natural vibration frequency refers to the inherent vibration frequency of a closed stagnant branch pipe under mechanical excitation.

[0139] Specifically, if the tee structure parameters are the inner diameter of the branch pipe, the outer diameter of the branch pipe, the length of the branch pipe, the elastic modulus of the branch pipe, and the density of the branch pipe; then, based on the tee structure parameters, the pipe natural vibration frequency is calculated to obtain the pipe natural vibration frequency parameters, including: calculating based on the elastic modulus of the branch pipe, the outer diameter of the branch pipe, the inner diameter of the branch pipe, and the length of the branch pipe to obtain the branch rigidity matrix; the branch rigidity matrix is used to characterize the ability of the branch pipe to resist deformation under external force; determining the branch mass matrix based on the density of the branch pipe, the inner diameter of the branch pipe, and the outer diameter of the branch pipe; constructing a branch characteristic function according to the branch rigidity matrix and the branch mass matrix, and solving the branch characteristic function to obtain the target branch eigenvalue; determining the pipe natural vibration frequency parameters based on the target branch eigenvalue.

[0140] Specifically, the inner diameter of the branch pipe and the outer diameter of the branch pipe are the geometric dimension parameters of the branch pipe, representing the inner and outer diameters of the branch pipe respectively; the elastic modulus of the branch pipe is the mechanical property parameter of the branch pipe, representing the rigidity of the branch pipe material in the elastic deformation stage; the density of the branch pipe is the mass distribution parameter of the branch pipe material, representing the mass per unit volume.

[0141] Specifically, the branch rigidity matrix is used to characterize the ability of the branch pipe to resist deformation under external force.

[0142] Specifically, the determination of the branch rigidity matrix can first calculate the moment of inertia of the branch pipe based on the inner diameter and outer diameter of the branch pipe to obtain the moment of inertia of the branch pipe; secondly, calculate the cross-sectional area of the branch pipe based on the inner diameter and outer diameter of the branch pipe to obtain the cross-sectional area of the branch pipe; finally, determine the moment of inertia of the branch pipe based on the moment of inertia of the branch pipe and the cross-sectional area of the branch pipe. Among them, the moment of inertia of the branch pipe is used to characterize the cross-sectional bending resistance ability of the branch pipe.

[0143] Specifically, the branch mass matrix is used to characterize the mass distribution of the branch pipe.

[0144] Specifically, the determination of the branch mass matrix can first determine the volume of the branch pipe based on the inner diameter and outer diameter of the branch pipe, and multiply the volume of the branch pipe by the density of the branch pipe to obtain the branch mass matrix.

[0145] Specifically, the target branch eigenvalue refers to the solution of the branch characteristic function and is related to the natural vibration frequency of the branch pipe; the target branch vibration mode refers to the branch vibration displacement form corresponding to the target branch eigenvalue and is used to describe the spatial deformation law of the branch pipe in different order modes (for example, the bending vibration mode in the first order mode shows unilateral swing, and the torsional vibration mode in the second order mode presents an S-shaped deformation).

[0146] Specifically, the branch pipe characteristic function is a function constructed based on the stiffness matrix and mass matrix for solving the vibration characteristics of the branch pipe. Specifically, the branch pipe characteristic function can be expressed by the following function:

[0147]

[0148] where K represents the branch pipe stiffness matrix, δ represents the target branch pipe eigenvalue, M represents the branch pipe mass matrix, represents the target branch pipe vibration mode.

[0149] Specifically, the natural vibration frequency parameter of the pipeline can be determined by the following formula:

[0150]

[0151] where f i represents the i-th natural vibration frequency parameter of the pipeline, and δ i represents the i-th target branch pipe eigenvalue.

[0152] In this embodiment, the natural vibration frequency of the pipeline is calculated based on the tee structure parameters to obtain the natural vibration frequency parameter of the pipeline, which can provide data support for subsequent fluid-acoustic-solid resonance tests.

[0153] The embodiments of the present application shown in steps S201 to S203 can obtain comprehensive key frequency parameters of the pipeline system by sequentially completing the hydrodynamic calculation for the tee structure, the acoustic vibration frequency calculation for the branch pipe, and the natural vibration frequency calculation of the pipeline based on the tee structure parameters, providing an important data basis for subsequent fluid-acoustic-solid multi-field coupling resonance tests, thereby helping to accurately identify potential resonance risks of the tee structure and taking effective control measures in a timely manner to enhance the operation safety and reliability of the pipeline system.

[0154] Referring to Figure 3 , in some embodiments, in step S103, a fluid-acoustic-solid resonance test is performed based on the tee vortex shedding frequency parameter, the pipeline acoustic mode frequency parameter, and the natural vibration frequency parameter of the pipeline to obtain pipeline resonance test data, which may include, but is not limited to:

[0155] Step S301: Project the tee vortex shedding frequency parameter onto a preset frequency coordinate axis to obtain the tee vortex shedding frequency projection parameter, project the pipeline acoustic mode frequency parameter onto the frequency coordinate axis to obtain the pipeline acoustic mode frequency projection parameter, and project the natural vibration frequency parameter of the pipeline onto the frequency coordinate axis to obtain the natural vibration frequency projection parameter of the pipeline;

[0156] Step S302: Perform an intersection test on the projection coordinate points of the tee vortex shedding frequency projection parameter, the pipeline acoustic mode frequency projection parameter, and the natural vibration frequency projection parameter of the pipeline to obtain intersection test data of the projection points;

[0157] In step S303, if the projection point intersection test data indicates that the three-way vortex shedding frequency projection parameter, the pipeline acoustic mode frequency projection parameter, and the pipeline self-vibration frequency projection parameter are located at the same coordinate point on the frequency coordinate axis, it is determined that fluid-acoustic-solid resonance occurs between the main pipeline and the branch pipeline.

[0158] In step S304, if the projection point intersection test data indicates that the three-way vortex shedding frequency projection parameter, the pipeline acoustic mode frequency projection parameter, and the pipeline self-vibration frequency projection parameter are not located at the same coordinate point on the frequency coordinate axis, it is determined that fluid-acoustic-solid resonance does not occur between the main pipeline and the branch pipeline.

[0159] In step S301 of some embodiments, specifically, the frequency coordinate axis is a virtual axis used to represent the vibration frequency of the pipeline system, and is used to uniformly compare different vibration frequency parameters. The frequency coordinate axis includes a pipeline flow velocity axis, a temperature axis, a pipeline vibration mode axis, a frequency axis, and a time axis.

[0160] Specifically, the three-way vortex shedding frequency projection parameter refers to the coordinate values obtained by mapping the three-way vortex shedding frequency parameter onto the time axis, the frequency axis, and the pipeline flow velocity axis.

[0161] Specifically, the pipeline acoustic mode frequency projection parameter refers to the coordinate values obtained by mapping the pipeline acoustic mode frequency parameter onto the time axis, the frequency axis, and the temperature axis.

[0162] Specifically, the pipeline self-vibration frequency projection parameter refers to the coordinate values obtained by mapping the pipeline self-vibration frequency parameter onto the time axis, the frequency axis, and the pipeline vibration mode axis.

[0163] In this embodiment, by projecting the three-way vortex shedding frequency parameter onto the preset frequency coordinate axis to obtain the three-way vortex shedding frequency projection parameter, projecting the pipeline acoustic mode frequency parameter onto the frequency coordinate axis to obtain the pipeline acoustic mode frequency projection parameter, and projecting the pipeline self-vibration frequency parameter onto the frequency coordinate axis to obtain the pipeline self-vibration frequency projection parameter, it is possible to unify the physical field frequency parameters from different sources onto the same frequency coordinate axis, convert the complex multi-physical field frequency relationship into an intuitive spatial position relationship, and provide a standardized comparison method for subsequent fluid-acoustic-solid resonance tests for the physical field frequency, so as to improve the accuracy of fluid-acoustic-solid resonance tests.

[0164] For step S302 of some embodiments, specifically, the projection point intersection test data refers to the data on whether the three-way vortex shedding frequency projection parameter, the pipeline acoustic mode frequency projection parameter, and the pipeline self-vibration frequency projection parameter fall on the same position on the frequency coordinate axis. This projection point intersection test data is used to characterize that the three-way vortex shedding frequency projection parameter, the pipeline acoustic mode frequency projection parameter, and the pipeline self-vibration frequency projection parameter are at the same coordinate point on the frequency coordinate axis, or the projection point intersection test data is used to characterize that the three-way vortex shedding frequency projection parameter, the pipeline acoustic mode frequency projection parameter, and the pipeline self-vibration frequency projection parameter are not at the same coordinate point on the frequency coordinate axis.

[0165] Specifically, when performing the projection coordinate point intersection test, the intersection tolerance range can be determined based on the actual application scenario.

[0166] For example, the intersection tolerance range between different frequency parameters can be represented by a frequency axis scale of ±2 Hz.

[0167] For step S303 of some embodiments, specifically, the pipeline resonance test data is used to characterize the occurrence of fluid-structure-acoustic resonance between the main pipeline and the branch pipeline, or the pipeline resonance test data is used to characterize the non-occurrence of fluid-structure-acoustic resonance between the main pipeline and the branch pipeline. Among them, fluid-structure-acoustic resonance refers to the resonance phenomenon caused by the interaction between hydrodynamic force, acoustic effect, and structural vibration.

[0168] Specifically, if the projection point intersection test data characterizes that the three-way vortex shedding frequency projection parameter, the pipeline acoustic mode frequency projection parameter, and the pipeline self-vibration frequency projection parameter are at the same coordinate point on the frequency coordinate axis, indicating that the frequencies of the three-way vortex shedding frequency parameter, the pipeline acoustic mode frequency parameter, and the pipeline self-vibration frequency parameter are consistent, then it is determined that fluid-structure-acoustic resonance occurs between the main pipeline and the branch pipeline.

[0169] For step S304 of some embodiments, specifically, if the projection point intersection test data characterizes that the three-way vortex shedding frequency projection parameter, the pipeline acoustic mode frequency projection parameter, and the pipeline self-vibration frequency projection parameter are not at the same coordinate point on the frequency coordinate axis, indicating that there is a situation where one of the vibration frequencies among the three-way vortex shedding frequency parameter, the pipeline acoustic mode frequency parameter, and the pipeline self-vibration frequency parameter is inconsistent with the other two vibration frequencies, then it is determined that fluid-structure-acoustic resonance does not occur between the main pipeline and the branch pipeline.

[0170] Specifically, the inconsistent situations include that the three-way vortex shedding frequency parameter, the pipeline acoustic mode frequency parameter, and the pipeline self-vibration frequency parameter are all inconsistent, or the three-way vortex shedding frequency parameter is inconsistent with the pipeline acoustic mode frequency parameter and the pipeline self-vibration frequency parameter, or the pipeline acoustic mode frequency parameter is inconsistent with the three-way vortex shedding frequency parameter and the pipeline self-vibration frequency parameter, or the pipeline self-vibration frequency parameter is inconsistent with the three-way vortex shedding frequency parameter and the pipeline acoustic mode frequency parameter.

[0171] The embodiments of the present application shown in steps S301 to S304 can, by sequentially completing the projection of frequency parameters, the intersection test of projection points, and the judgment of acoustic-fluid-structure resonance, achieve parallel calculation of multi-source data of the flow field, acoustic field, and structure field under the same framework through the co-variable coaxial mapping method, thereby effectively identifying the fluid-acoustic-structure multi-field coupling resonance phenomenon in the pipeline system, which helps to take control measures in advance for the pipeline system where the fluid-acoustic-structure resonance phenomenon occurs, and ensures the safety of the pipeline system operation.

[0172] Refer to Figure 4 , which is a schematic diagram of co-variable coaxial projection provided by the embodiments of the present application. This schematic diagram shows a frequency-time frequency coordinate axis, and this frequency coordinate axis includes a pipeline flow velocity axis, a temperature axis, a pipeline vibration mode axis, a frequency axis, and a time axis. The triangles, squares, and circles in the figure respectively represent the changes of the tee vortex shedding frequency, the pipeline acoustic mode frequency, and the pipeline natural vibration frequency at different time points and different conditions.

[0173] Specifically, the triangle (△) on the frequency coordinate axis represents the optimal tee vortex shedding frequency parameter fu0 at the main pipeline flow velocity u0 at time t0. The square (□) represents the pipeline acoustic mode frequency parameter fT0 at the main pipeline temperature T0 at time t0. The circle (●) represents the pipeline natural vibration frequency parameter fp of the nth order of the branch pipe at time t0. Among them, p1, p2, p3, and p4 respectively represent the first order, the second order, the third order, and the fourth order, and fp1, fp2, fp3, and fp4 respectively represent the pipeline natural vibration frequency parameter of the first order, the pipeline natural vibration frequency parameter of the second order, the pipeline natural vibration frequency parameter of the third order, and the pipeline natural vibration frequency parameter of the fourth order.

[0174] Specifically, if the tee vortex shedding frequency projection parameter, the pipeline acoustic mode frequency projection parameter, and the pipeline natural vibration frequency projection parameter intersect at the same coordinate point on the frequency coordinate axis, it indicates that there is a fluid-acoustic-structure resonance phenomenon in the pipeline system; if the tee vortex shedding frequency projection parameter, the pipeline acoustic mode frequency projection parameter, and the pipeline natural vibration frequency projection parameter do not intersect at the same coordinate point on the frequency coordinate axis, it indicates that there is no fluid-acoustic-structure resonance phenomenon in the pipeline system.

[0175] In this embodiment, by projecting different frequency parameters onto the same frequency coordinate axis, these parameters can be intuitively compared and analyzed, thereby quickly identifying whether there is a multi-field coupling resonance phenomenon, which not only improves the efficiency and accuracy of resonance detection, but also provides important technical support for the safe operation of the pipeline system.

[0176] Refer to Figure 5 , in some embodiments, when the pipeline resonance test data indicates that there is a fluid-acoustic-structure resonance between the main pipeline and the branch pipe in step S104, the fluid-acoustic-structure resonance control measures executed on the pipeline system may include, but are not limited to:

[0177] Step S501, when the flow-acoustic-solid resonance occurs between the main pipe and the branch pipe in the pipeline resonance inspection data, execute the first control measure for the pipeline system to adjust the three-way vortex shedding frequency parameter;

[0178] Step S502, after executing the first control measure, return to execute the hydrodynamic calculation for the three-way structure based on the updated three-way structure parameters and the main pipe working condition data until the pipeline resonance inspection data indicates that the flow-acoustic-solid resonance no longer occurs between the main pipe and the branch pipe.

[0179] In step S501 of some embodiments, specifically, the first control measure refers to the specific measure taken for the pipeline system to adjust the three-way vortex shedding frequency parameter.

[0180] Specifically, the three-way structure in the pipeline system includes a three-way component, and the three-way component is used to connect the branch pipe and the main pipe in the pipeline system. Executing the first control measure for the pipeline system to adjust the three-way vortex shedding frequency parameter includes: performing a three-way component replacement operation on the pipeline system to replace the original three-way inspection component in the pipeline system with a target three-way component; wherein, the chamfer radius of the target three-way component is inconsistent with the chamfer radius of the original three-way inspection component.

[0181] Specifically, since the flow-acoustic-solid resonance is much more complex for the pipeline system than a single type of vibration, the core objective of the first control measure is to destroy the resonance matching of the flow field, sound field and structural field frequencies. And because the functional requirements of the pipeline system limit the internal cross-sectional area and resistance of the main pipe and the branch pipe, in order to ensure that the geometric structure of the main pipe system does not change, the measure of actively replacing the three-way component can be specifically taken to adjust the three-way vortex shedding frequency parameter, so that the three-way vortex shedding frequency projection parameter, the pipeline acoustic mode frequency projection parameter and the pipeline self-vibration frequency projection parameter are not located at the same coordinate point on the frequency coordinate axis.

[0182] For example, if the chamfer radius of the original three-way inspection component is 12 mm, then by replacing the target three-way component with a chamfer radius of 8 mm, the flow velocity in the main pipe can be changed to adjust the three-way vortex shedding frequency parameter at the three-way structure. Specifically, if resonance is detected when the flow velocity of the main pipe is 3 m / s, by using the target three-way component with a chamfer radius of 8 mm, the flow velocity can be adjusted to 2.5 m / s, so that the three-way vortex shedding frequency parameter changes, thereby avoiding the occurrence of flow-acoustic-solid resonance.

[0183] In step S502 of some embodiments, after executing the first control measure, it is necessary to return to execute the recalculation of the fluid intersection vibration frequency based on the updated three-way structure parameters and the main pipe working condition data until the pipeline resonance inspection data indicates that the flow-acoustic resonance is eliminated. This iterative process is the key link to ensure the effectiveness of the first control measure.

[0184] For example, if it is detected that after replacing the target tee component in the tee structure, the vortex shedding frequency of the tee decreases from 105 Hz to 88 Hz, and the difference between the pipe acoustic modal frequency of 103 Hz and the natural vibration frequency of the pipe of 105 Hz is greater than the preset intersection tolerance frequency of 2 Hz, the occurrence of fluid-acoustic-solid resonance can be avoided. If it is detected that after replacing the target tee component in the tee structure, the vortex shedding frequency of the tee only decreases from 105 Hz to 101 Hz, since the adjusted vortex shedding frequency of the tee and the pipe acoustic modal frequency do not satisfy the condition that the intersection tolerance frequency is greater than 2 Hz, the step of replacing the target tee component needs to be re-executed until the pipe resonance test data indicates that no fluid-acoustic resonance occurs between the main pipe and the branch pipe.

[0185] In this embodiment, by implementing the first control measure for the pipeline system to adjust the vortex shedding frequency parameter of the tee, the first measure to control fluid-acoustic-solid vibration can be actively taken without affecting the internal cross-sectional area and resistance of the main pipe and the branch pipe. Additionally, cyclic verification is combined to ensure the effectiveness of the first control measure for actively preventing multi-field coupling resonance in the pipeline, effectively reducing the damage of multi-field coupling resonance to the pipeline system, and improving the operation safety and reliability of the pipeline system.

[0186] In the embodiment of the present application shown in steps S501 to S502, during the pipeline system design stage, by implementing the first control measure for the pipeline system to adjust the vortex shedding frequency parameter of the tee, the first measure to control fluid-acoustic-solid vibration can be actively taken without affecting the internal cross-sectional area and resistance of the main pipe and the branch pipe. Cyclic verification is also combined to ensure the effectiveness of the first control measure, solving the problem in the traditional method where an internal insert is added at the connection of the tee in the pipeline, increasing the discharge resistance of the branch pipe and prone to falling off due to fatigue failure. It effectively reduces the damage of multi-field coupling resonance to the pipeline system, extends the service life of the pipeline, and improves the operation safety and reliability of the pipeline system.

[0187] Referring to Figure 6 , in some embodiments, when the pipeline resonance test data indicates that fluid-acoustic-solid resonance occurs between the main pipe and the branch pipe in step S104, the fluid-acoustic-solid resonance control measure for the branch pipe may further include, but is not limited to:

[0188] Step S601, when the pipeline resonance test data indicates that fluid-acoustic-solid resonance occurs between the main pipe and the branch pipe, implement the second control measure for the branch pipe to adjust the pipe acoustic modal frequency parameter;

[0189] Step S602, after implementing the second control measure, return to perform the acoustic vibration frequency calculation for the branch pipe based on the tee structure parameters and the main pipe operating condition data until the pipeline resonance test data indicates that no fluid-acoustic-solid resonance occurs between the main pipe and the branch pipe.

[0190] Step S601 of some embodiments. Specifically, the second control measure refers to the measure of adding an isolation valve to the branch pipe. The isolation valve is used to adjust the effective length of the branch pipe to adjust the pipeline acoustic modal frequency parameters, so that the tee vortex shedding frequency projection parameter, the pipeline acoustic modal frequency projection parameter, and the pipeline natural vibration frequency projection parameter are not located at the same coordinate point on the frequency coordinate axis.

[0191] Specifically, the pipeline system includes an isolation valve. The isolation valve is used in the pipeline system to control the length of the branch pipe and execute the second control measure for the branch pipe to adjust the pipeline acoustic modal frequency parameters, including: performing an isolation valve installation operation for the branch pipe to install the isolation valve onto the branch pipe.

[0192] Specifically, the core objective of the second control measure is to destroy the resonance matching of the flow field, sound field, and structural field frequencies. And when it is impossible to change the length of the branch pipe due to layout space or branch pipe discharge resistance requirements in the pipeline system, an isolation valve can be added to the branch pipe. When acoustic-fluid-structure resonance occurs, the effective length of the branch pipe can be changed by opening and closing the isolation valve.

[0193] Furthermore, when the isolation valve is in the fully closed state, the length of the branch pipe can be shortened to the distance from the valve to the tee; when the isolation valve is partially opened, the length of the branch pipe can be increased, thereby realizing the adjustment of the pipeline acoustic modal frequency parameters.

[0194] Step S602 of some embodiments. Specifically, after executing the second control measure, it is necessary to return to the step of recalculating the flow-acoustic vibration frequency until the pipeline resonance test data indicates that no flow-acoustic resonance occurs between the main pipeline and the branch pipe.

[0195] For example, if it is detected that the pipeline acoustic modal frequency parameter is 128 Hz, the tee vortex shedding frequency parameter is 126 Hz, and the pipeline natural vibration frequency parameter is 130 Hz, forming a triple coupling. An isolation valve is added outside the branch pipe, and the valve of the isolation valve is opened to increase the effective length of the branch pipe, thereby adjusting the pipeline acoustic modal frequency parameter to 115 Hz. And the adjusted pipeline acoustic modal frequency parameter satisfies the condition that the intersection tolerance frequency with the tee vortex shedding frequency parameter and the pipeline natural vibration frequency parameter is greater than 2 Hz, which can avoid the occurrence of flow-acoustic-solid resonance. If it is detected that after adjusting the isolation valve, the pipeline acoustic modal frequency parameter only drops from 128 Hz to 126 Hz, since the adjusted pipeline acoustic modal frequency parameter and the tee vortex shedding frequency parameter do not satisfy the condition that the intersection tolerance frequency is greater than 2 Hz, it is necessary to re-control the opening degree of the isolation valve to re-execute the step of calculating the acoustic vibration frequency for the branch pipe based on the tee structure parameters and the main pipeline operating conditions data until the pipeline resonance test data indicates that no flow-acoustic resonance occurs between the main pipeline and the branch pipe.

[0196] In this embodiment, by implementing the second control measure for the branch pipe to adjust the pipeline acoustic modal frequency parameters, when the layout space of the pipeline system or the discharge resistance requirement of the branch pipe can be met, the second measure for controlling the acoustic fluid-solid vibration can be actively taken. Additionally, cyclic verification is combined to ensure the effectiveness of the second control measure, effectively reducing the damage of multi-field coupling resonance to the pipeline system and improving the operation safety and reliability of the pipeline system.

[0197] The embodiment of the present application provided via steps S601 to S602, during the pipeline system design stage, by sequentially executing the cyclic steps of pipeline acoustic modal frequency parameter inspection, adjustment, and verification, it is possible to dynamically adjust the second control measure based on the real-time monitored pipeline acoustic modal frequency parameters, and also combine cyclic verification to ensure the effectiveness of the second control measure, so as to effectively avoid the fluid-acoustic-solid resonance phenomenon in the pipeline system, reduce the damage of multi-field coupling resonance to the pipeline system, extend the service life of the pipeline, and improve the operation safety and reliability of the pipeline system.

[0198] Referring to Figure 7 , in some embodiments, when the pipeline resonance inspection data indicates the occurrence of fluid-acoustic-solid resonance between the main pipeline and the branch pipe in step S104, the fluid-acoustic-solid resonance control measure is implemented for the branch pipe, and it may further include, but is not limited to:

[0199] Step S701, when the pipeline resonance inspection data indicates the occurrence of fluid-acoustic-solid resonance between the main pipeline and the branch pipe, implement the third control measure for the branch pipe to adjust the pipeline natural vibration frequency parameters;

[0200] Step S702, after implementing the third control measure, return to perform the calculation of the pipeline natural vibration frequency based on the tee structure parameters until the pipeline resonance inspection data indicates that no fluid-acoustic-solid resonance occurs between the main pipeline and the branch pipe.

[0201] In step S701 of some embodiments, specifically, the third control measure refers to the measure of adjusting the position of the support for the branch pipe. The position adjustment of the support is used to adjust the original structural stiffness and mass distribution of the branch pipe in the pipeline system to adjust the pipeline acoustic modal frequency parameters, so that the three-way vortex shedding frequency projection parameter, the pipeline acoustic modal frequency projection parameter, and the pipeline natural vibration frequency projection parameter are not located at the same coordinate point on the frequency coordinate axis.

[0202] Specifically, the pipeline system includes a support. The support is used to connect the branch pipe in the pipeline system. Implementing the third control measure for the branch pipe to adjust the pipeline natural vibration frequency parameters includes: performing an operation to adjust the position of the support for the branch pipe to adjust the original position of the support to the target position.

[0203] Specifically, if the natural vibration frequency of the branch pipe is close to the three-way vortex shedding frequency parameter and the pipeline acoustic mode frequency parameter due to the position of the original support, by moving the support towards one end of the branch pipe, the rigidity of the branch pipe can be increased, thereby increasing the natural vibration frequency of the branch pipe to achieve decoupling of the three-way vortex shedding frequency parameter, the pipeline acoustic mode frequency parameter, and the pipeline natural vibration frequency parameter.

[0204] In step S702 of some embodiments, specifically, after implementing the third control measure, it is necessary to return to the step of recalculating the natural vibration frequency of the pipeline until the pipeline resonance test data indicates that no fluid-structure-acoustic resonance occurs between the main pipeline and the branch pipe.

[0205] For example, if it is detected that the pipeline natural vibration frequency parameter is 130 Hz, the pipeline acoustic mode frequency parameter is 128 Hz, and the three-way vortex shedding frequency parameter is 126 Hz, forming a triple coupling, a measure of adjusting the position of the support for the branch pipe is taken to adjust the stiffness and mass distribution of the branch pipe, thereby adjusting the pipeline acoustic mode frequency parameter to 105 Hz. And the condition that the intersection tolerance frequency between the adjusted pipeline natural vibration frequency parameter, the three-way vortex shedding frequency parameter, and the pipeline acoustic mode frequency parameter is greater than 2 Hz is satisfied, which can avoid the occurrence of fluid-structure-acoustic resonance. If it is detected that after adjusting the position of the support, the pipeline natural vibration frequency parameter only drops from 130 Hz to 126 Hz, since the adjusted pipeline natural vibration frequency parameter, the pipeline acoustic mode frequency parameter, and the three-way vortex shedding frequency parameter do not satisfy the condition that the intersection tolerance frequency is greater than 2 Hz, it is necessary to readjust the position of the support to re-execute the step of calculating the natural vibration frequency of the pipeline for the branch pipe based on the three-way structure parameters and the main pipeline operating conditions data until the pipeline resonance test data indicates that no fluid-structure-acoustic resonance occurs between the main pipeline and the branch pipe.

[0206] Through the embodiments of the present application shown in steps S701 to S702, in the pipeline system design stage, by sequentially executing the cyclic steps of pipeline natural vibration frequency parameter inspection, adjustment, and verification, it is possible to dynamically adjust the third control measure based on the real-time monitored pipeline natural vibration frequency parameter, and also combine cyclic verification to ensure the effectiveness of the third control measure, solving the problem that surfacing upstream of the main pipeline three-way increases the fluid resistance of the main pipeline, effectively avoiding the fluid-structure-acoustic resonance phenomenon in the pipeline system, reducing the damage of multi-field coupling resonance to the pipeline system, extending the service life of the pipeline, and improving the operation safety and reliability of the pipeline system.

[0207] The multi-field coupling resonance control method for pipelines provided by the embodiments of the present application is applied to pipeline resonance control of a pipeline system. The pipeline system includes a main pipeline and a branch pipeline. One end of the branch pipeline is connected to the main pipeline to form a tee structure at the pipeline connection position between the branch pipeline and the main pipeline, and it has at least the following beneficial effects: First, obtain the tee structure parameters corresponding to the tee structure and the main pipeline condition data corresponding to the main pipeline, and calculate the tee vortex shedding frequency parameters, pipeline acoustic mode frequency parameters, and pipeline self-vibration frequency parameters corresponding to the pipeline system based on the tee structure parameters and the main pipeline condition data, providing data support for subsequent pipeline resonance inspection; Second, conduct fluid-structure-acoustic resonance inspection based on the tee vortex shedding frequency parameters, pipeline acoustic mode frequency parameters, and pipeline self-vibration frequency parameters to obtain pipeline resonance inspection data, and through coaxial variable projection, realize parallel calculation of multi-source data of the flow field, acoustic field, and structural field under the same framework, thereby effectively identifying the fluid-structure-acoustic resonance phenomenon in the pipeline system. Finally, by taking at least one of the measures of replacing the tee component, adding an isolation valve, and adjusting the position of the support during the pipeline system design stage, it is possible to actively prevent the risk of fluid-structure-acoustic resonance in the pipeline system without changing the functional requirements of the pipeline system, without adding additional pipe components, and without affecting the safety of the pipeline system, improving the operation safety and reliability of the pipeline system.

[0208] Refer to Figure 8 , Figure 8 FIG. is an optional structural schematic diagram of the pipeline system provided by the embodiments of the present application. FIG. (a) shows the pipeline system composed of the original tee inspection part, and FIG. (b) shows the pipeline system composed of the target tee part. The pipeline system provided by the embodiments of the present application includes: a main pipeline 100, a branch pipeline 200, and a target tee part 300.

[0209] Specifically, the main pipeline 100 is used to perform fluid transportation tasks. One end of the branch pipeline 200 is connected to the main pipeline 100. The target tee part 300 is used to replace the original tee inspection part originally installed in the pipeline system during the process of implementing the fluid-structure-acoustic resonance control measures to connect the branch pipeline 200 and the main pipeline 100, so as to adjust the tee vortex shedding frequency parameters, so that the pipeline resonance inspection data corresponding to the pipeline system indicates that there is no fluid-structure-acoustic resonance between the main pipeline 100 and the branch pipeline 200.

[0210] It should be noted that the difference between the original tee inspection part and the target tee part lies in the different chamfer radii.

[0211] The pipeline system provided by the embodiments of the present application has the following technical effects: In the pipeline system design stage, by using the target tee to replace the original tee inspection piece, the tee vortex shedding frequency parameter can be effectively adjusted, the risk of flow sound resonance between the main pipeline and the branch pipeline can be reduced, the problem that surfacing is carried out upstream of the main pipeline tee, increasing the fluid resistance of the main pipeline is effectively solved, and the problem that an internal insert is added at the connection of the pipeline tee, increasing the discharge resistance of the branch pipeline and easily falling off due to fatigue failure is also solved, improving the operation safety of the pipeline system.

[0212] Refer to Figure 9 , Figure 9 which is another schematic diagram of the pipeline system provided by the embodiments of the present application. Figure (a) shows the pipeline system without an isolation valve installed, and Figure (b) shows the pipeline system with an isolation valve added. The pipeline system provided by this embodiment includes: a main pipeline 100, a branch pipeline 200, and an isolation valve 400.

[0213] Specifically, the main pipeline 100 is used to perform fluid transportation tasks. One end of the branch pipeline 200 is connected to the main pipeline 100. The isolation valve 400 is sleeved outside the branch pipeline 200. The isolation valve 400 is used to adjust the original pipeline length of the branch pipeline 200 in the pipeline system during the implementation of the flow sound-solid resonance control measures, so as to adjust the pipeline acoustic mode frequency parameter, so that the pipeline resonance inspection data corresponding to the pipeline system indicates that there is no flow sound resonance between the main pipeline 100 and the branch pipeline 200.

[0214] Another pipeline system provided by the embodiments of the present application has the following technical effects. In the pipeline system design stage, by taking the control measure of actively installing an isolation valve, the pipeline acoustic mode frequency parameter can be effectively adjusted, thereby effectively avoiding the flow sound resonance phenomenon in the pipeline system, reducing the damage of multi-field coupling resonance to the pipeline system, and effectively solving the problem that surfacing is carried out upstream of the main pipeline tee, increasing the fluid resistance of the main pipeline, and also solving the problem that an internal insert is added at the connection of the pipeline tee, increasing the discharge resistance of the branch pipeline and easily falling off due to fatigue failure, improving the operation safety of the pipeline system.

[0215] Refer to Figure 10 , Figure 10 which is another schematic diagram of the pipeline system provided by the embodiments of the present application. Figure (a) shows the pipeline system at the original support position, and Figure (b) shows the pipeline system at the target support position. The pipeline system provided by this embodiment includes: a main pipeline 100, a branch pipeline 200, and a support 500.

[0216] Specifically, the main pipeline 100 is used for fluid transportation tasks. One end of the branch pipeline 200 is connected to the main pipeline 100. The bracket 500 is connected to the outside of the branch pipeline 200. The bracket 500 is used to adjust the original structural stiffness and mass distribution of the branch pipeline 200 in the pipeline system during the implementation of the over-flow acoustic-solid resonance control measures, so as to adjust the pipeline natural vibration frequency parameters, so that the pipeline resonance test data corresponding to the pipeline system indicates that there is no flow-acoustic-solid resonance between the main pipeline 100 and the branch pipeline 200.

[0217] It should be noted that adjusting the original structural stiffness and mass distribution of the branch pipeline in the pipeline system is achieved by adjusting the original bracket position to the target bracket position.

[0218] Another pipeline system provided by the embodiments of the present application has the following technical effects. During the pipeline system design stage, by taking the control measure of actively adjusting the bracket position, the pipeline natural vibration frequency parameters can be effectively adjusted, thereby effectively avoiding the flow-acoustic-solid resonance phenomenon in the pipeline system, reducing the damage of multi-field coupling resonance to the pipeline system, and effectively solving the problem that surfacing is carried out upstream of the main pipeline tee, increasing the fluid resistance of the main pipeline, and also solving the problem that an internal insert is added at the connection of the pipeline tee, increasing the discharge resistance of the branch pipeline and easily causing the phenomenon of falling off due to fatigue failure, improving the operation safety of the pipeline system.

[0219] Refer to Figure 11 , Figure 11 is another schematic diagram of the pipeline system provided by the embodiments of the present application. Figure (a) shows the top view of the pipeline system, and Figure (b) shows the side view of the pipeline system. The pipeline system provided in this embodiment includes: a main pipeline 100, a branch pipeline 200, a pipe clamp 600, a spring group 700, a spring box 800, a mass block 900, a threaded connecting rod 1000, a nut 1100, a base support 1200, and a spring box fixing sleeve 1300.

[0220] Specifically, the main pipeline 100 is used for fluid transportation tasks. One end of the branch pipeline 200 is connected to the main pipeline 100. The pipe clamp 600 is sleeved outside the branch pipeline 200. The spring group 700 includes springs arranged axially symmetrically in the horizontal direction and springs in the vertical direction, and is used to absorb vibrations generated by the branch pipeline 200 in various directions. Inside the spring box 800, there are a mass block 900 and the spring group 700. The spring box 800 is connected to the base support 1200 through the spring box fixing sleeve 1300. The spring box 800 is used to rotate around the axis according to the vibration direction of the branch pipeline 200 to adjust the angle of the spring box 800. The mass block 900 is connected to the inner wall of the spring box 800 through the multi-axial spring group 700. The threaded link 1000 is used to connect the mass block 900 and the pipe clamp 600. When the branch pipeline 200 vibrates, the distance between the mass block 900 and the branch pipeline 200 is adjusted axially along the threaded link 1000 to ensure that the mass block 900 is located at the center of the spring box 800. The nut 1100 is used to fix the connection between the threaded link 1000 and the mass block 900. The base support 1200 is used to connect the spring box 800 to a preset load-bearing device. The spring box fixing sleeve 1300 adopts a detachable structure and is used to connect the spring box 800 and the base support 1200. It should be noted that the preset load-bearing device can be the plant structure of a nuclear power plant.

[0221] Specifically, the spring group 700, the spring box 800, the mass block 900, the nut 1100, the base support 1200, and the spring box fixing sleeve 1300 together form a shock absorber. By connecting the pipe clamp through the threaded link 1000, when the branch pipeline vibrates, the distance between the branch pipeline and the shock absorber can be dynamically adjusted through the threaded link 1000, so that when the branch pipeline vibrates, the mass block is always in the central position, and three-way vibration absorption is realized through the pipe clamp, threaded link, and spring box structure, effectively eliminating the vibration generated by the branch pipeline.

[0222] Another pipeline system provided by the embodiments of the present application has the following technical effects. If after taking at least one of the first, second, and third control measures during the pipeline design stage, the resonance risk is low after inspection, but the phenomenon of three-field coupling resonance exceeding the standard occurs after the pipeline system is installed and operated, then the branch pipeline is connected to the shock absorber through the threaded link. When the branch pipeline vibrates, the distance between the branch pipeline and the shock absorber is dynamically adjusted. Specifically, through the directional rotation function of the spring box, the mass block is always in the center of the spring box, and it can be dynamically adjusted according to the vibration direction of the branch pipeline to meet the three-way vibration absorption requirements of the pipe clamp, threaded link, and spring box structure, so as to ensure that the shock absorber can effectively play the shock absorption role, and the vibration energy is dispersed in combination with the base support, thereby realizing the passive suppression of fluid-structure-acoustic resonance and ensuring the safe operation of the pipeline system.
