Description

Technical Field

[0001] This invention relates to the field of industrial tank stress testing technology, and in particular to a stress testing method for a scaled-down model of an industrial tank, a computer-readable storage medium, a stress testing device for a scaled-down model of an industrial tank, and a stress testing platform for a scaled-down model of an industrial tank. Background Technology

[0002] Currently, common industrial tanks (such as above-ground vertical LNG storage tanks or common horizontal metal storage tanks and other pressure-bearing equipment) are usually installed outdoors for open-air operations. As they work continuously in complex outdoor environments (such as seasonal temperature changes, large day-night temperature differences, high and uneven solar radiation intensity during the day), the outer surface of the tank is easily subjected to large thermal shocks and temperature gradients. This leads to inconsistent thermal expansion and contraction in different parts, resulting in large thermal stresses. In some cases, the stress test values ​​exceed the allowable stress, causing structural failure.

[0003] However, due to the large size of the industrial tanks in the relevant technologies, and the limited space in the environmental test chamber, it is impossible to conduct environmental tolerance tests on the tanks using real industrial tank prototypes in the environmental test chamber. Summary of the Invention

[0004] This invention aims to at least partially solve one of the technical problems in related technologies. Therefore, the first objective of this invention is to propose a stress testing method for a scaled-down model of an industrial tank, enabling temperature-stress testing of the scaled-down model under varying external environmental conditions in a laboratory setting, reducing testing costs, and providing data reference for the design of industrial tank structural parameters.

[0005] A second objective of this invention is to provide a computer-readable storage medium.

[0006] The third objective of this invention is to provide a stress testing device for a scaled-down model of an industrial tank.

[0007] The fourth objective of this invention is to provide a stress testing platform for a scaled-down model of an industrial tank.

[0008] To achieve the above objectives, the stress testing method for a scaled-down model of an industrial tank proposed in the first aspect of the present invention includes: dimensionlessizing the energy balance equation of the tank and constructing a first dimensionless parameter, a second dimensionless parameter, and a third dimensionless parameter corresponding to the actual test conditions of the tank; obtaining the scaled-down model dimensions and determining the test conditions of the scaled-down model based on the scaled-down model dimensions, the first dimensionless parameter, the second dimensionless parameter, and the third dimensionless parameter; and performing stress testing on the scaled-down model of the industrial tank based on the test conditions of the scaled-down model.

[0009] According to the stress testing method for a scaled-down industrial tank model of the present invention, the energy balance equation of the tank is dimensionless, and first, second, and third dimensionless parameters corresponding to the actual test conditions of the tank are constructed. Then, the scaled-down model dimensions are obtained, and the test conditions of the scaled-down model are determined based on the scaled-down model dimensions, the first, second, and third dimensionless parameters, and stress testing of the scaled-down industrial tank model is performed based on these test conditions. Thus, by using the first, second, and third dimensionless parameters corresponding to the actual test conditions of the tank, the test conditions of the scaled-down tank model corresponding to the scaled-down model dimensions are determined. This allows for temperature-stress testing of the scaled-down industrial tank model under varying external environmental conditions in the laboratory, reducing testing costs and providing data reference for the design of industrial tank structural parameters.

[0010] Furthermore, the stress testing method for the scaled-down model of an industrial tank according to the above embodiments of the present invention may also have the following additional technical features:

[0012] According to one embodiment of the present invention, determining the test parameters of the scaled-down model includes: replacing the tank size in the first dimensionless parameter with the scaled-down model size, and adjusting the test time to keep the first dimensionless parameter unchanged; replacing the tank size in the second dimensionless parameter with the scaled-down model size, and adjusting the test irradiance value to keep the second dimensionless parameter unchanged; replacing the tank size in the third dimensionless parameter with the scaled-down model size, and adjusting the test convective heat transfer coefficient to keep the third dimensionless parameter unchanged; and determining the test parameters of the scaled-down model based on the adjusted test time, the adjusted test irradiance value, and the adjusted test convective heat transfer coefficient.

[0013] According to one embodiment of the present invention, adjusting the test time to keep the first dimensionless parameter unchanged includes: determining the reduction ratio of the actual tank size after replacing the tank size in the first dimensionless parameter with the scaled-down model size; and adjusting the test time according to the reduction ratio of the actual tank size.

[0014] According to one embodiment of the present invention, adjusting the test irradiance value to keep the second dimensionless parameter unchanged includes: determining the reduction ratio of the actual tank size after replacing the tank size in the second dimensionless parameter with the scaled-down model size; and adjusting the test irradiance value according to the reduction ratio of the actual tank size.

[0015] According to one embodiment of the present invention, adjusting the experimental convective heat transfer coefficient to keep the third dimensionless parameter unchanged includes: determining the reduction ratio of the actual tank size after replacing the tank size in the third dimensionless parameter with the scaled-down model size; and adjusting the experimental convective heat transfer coefficient according to the reduction ratio of the actual tank size.

[0016] According to one embodiment of the present invention, the experimental convective heat transfer coefficient is adjusted according to the following formula: h0=6.5+3.3*Va, where Va is the fan speed.

[0017] To achieve the above objectives, a computer-readable storage medium is provided in a second aspect embodiment of the present invention, which stores a stress testing program for a scaled-down model of an industrial tank. When the stress testing program for the scaled-down model of the industrial tank is executed by a processor, it implements the stress testing method for the scaled-down model of the industrial tank described in the embodiments of the present invention.

[0018] According to embodiments of the present invention, a computer-readable storage medium can execute a stress testing program for a scaled-down model of an industrial tank stored thereon via a processor. This enables temperature-stress testing of the scaled-down model of the industrial tank under varying external environmental conditions in a laboratory setting, reducing testing costs and providing data references for the design of structural parameters of industrial tanks.

[0019] To achieve the above objectives, the stress testing device for a scaled-down model of an industrial tank proposed in the third aspect of the present invention includes: a construction module for dimensionlessly converting the energy balance equation of the tank and constructing a first dimensionless parameter, a second dimensionless parameter, and a third dimensionless parameter corresponding to the actual test conditions of the tank; a determination module for obtaining the scaled-down model dimensions and determining the test conditions of the scaled-down model based on the scaled-down model dimensions, the first dimensionless parameter, the second dimensionless parameter, and the third dimensionless parameter; and a testing module for performing stress testing on the scaled-down model of the industrial tank based on the test conditions of the scaled-down model.

[0020] The stress testing device for a scaled-down industrial tank model according to an embodiment of the present invention uses a construction module to make the tank's energy balance equation dimensionless and constructs a first dimensionless parameter, a second dimensionless parameter, and a third dimensionless parameter corresponding to the actual tank test conditions. Then, a determination module obtains the scaled-down model dimensions, and based on the scaled-down model dimensions, the first dimensionless parameter, the second dimensionless parameter, and the third dimensionless parameter, determines the scaled-down model test conditions. Finally, a testing module performs stress testing on the scaled-down industrial tank model based on the scaled-down model test conditions. Thus, by using the first dimensionless parameter, the second dimensionless parameter, and the third dimensionless parameter corresponding to the actual tank test conditions, the test conditions of the scaled-down tank model corresponding to the scaled-down model dimensions are determined. This allows for temperature-stress testing of the scaled-down industrial tank model under varying external environmental conditions in the laboratory, reducing testing costs and providing data reference for the design of industrial tank structural parameters.

[0021] To achieve the above objectives, the stress testing platform for the scaled-down industrial tank model proposed in the fourth aspect of the present invention includes the stress testing device for the scaled-down industrial tank model described in the above-described embodiments of the present invention.

[0031] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0032] The following description, with reference to the accompanying drawings, describes a stress testing method, a computer-readable storage medium, a stress testing device, and a stress testing platform for a scaled-down industrial tank model according to embodiments of the present invention.

[0033] Figure 1 This is a schematic flowchart of a stress testing method for a scaled-down model of an industrial tank according to an embodiment of the present invention.

[0034] Specifically, in some embodiments of the present invention, such as Figure 1 As shown, the stress testing method for a scaled-down model of an industrial tank includes:

[0035] S101, the energy balance equation of the tank is made dimensionless, and the first dimensionless parameter, the second dimensionless parameter and the third dimensionless parameter corresponding to the actual tank test conditions are constructed.

[0036] It is understood that, in this embodiment of the present invention, the actual tank test conditions parameters may include the size of the actual tank, the time of the actual tank test, the irradiance value of the actual tank during the test, and the convective heat transfer coefficient of the actual tank during the test.

[0037] Specifically, in this embodiment of the present invention, the energy balance equation of the tank can be obtained in the following manner:

[0038] The three-dimensional unsteady heat conduction differential equation in Cartesian coordinates can be expressed as:

[0039]

[0040] The three-dimensional convective heat transfer differential equation can be expressed as:

[0041]

[0042] The heat transfer from solar radiation can be expressed as:

[0043]

[0044] Based on the above formulas (1), (2), and (3), the energy balance equation of the actual tank under outdoor composite environment (temperature difference - solar radiation) can be calculated:

[0045]

[0046] Where ρ is the density of the tank material, c is the specific heat capacity of the tank material, λ is the thermal conductivity of the tank material, t is the ambient temperature of the tank material, x, y, z are the length, width, and height of the tank material, α is the absorptivity, δ is the thickness of the tank material, and t a t represents the ambient temperature, and t represents the surface temperature of the tank material.

[0047] More specifically, in some embodiments of the present invention, the first dimensionless parameter is The second dimensionless parameter is The third dimensionless parameter is Where L is the tank size, τ0 is the test time, I0 is the test irradiance value, and h0 is the test convective heat transfer coefficient.

[0048] Specifically, in this embodiment of the present invention, dimensionless transformation of the above formula (4) yields:

[0049]

[0050] At this time, The first dimensionless parameter π1 corresponding to the test time τ0, the second dimensionless parameter π2 corresponding to the test irradiance value I0, and the third dimensionless parameter π3 corresponding to the test convective heat transfer coefficient h0 are constructed.

[0051] It should be noted that in the above embodiments of the present invention, the asterisk (*) in the formula represents the dimensionless formula.

[0052] S102, obtain the scaled-down model dimensions, and determine the test parameters of the scaled-down model based on the scaled-down model dimensions, the first dimensionless parameter, the second dimensionless parameter, and the third dimensionless parameter.

[0053] It is understood that, in this embodiment of the present invention, the first dimensionless parameter, the second dimensionless parameter, and the third dimensionless parameter can be adaptively adjusted based on the scaled-down model size, so that the first dimensionless parameter, the second dimensionless parameter, and the third dimensionless parameter remain unchanged, so that the tank energy balance equations of the above formulas (4) and (5) are consistent, thereby determining the scaled-down model test condition parameters (industrial tank scaled-down model test time, industrial tank scaled-down model test irradiance value, and industrial tank scaled-down model convective heat transfer coefficient) required for conducting experiments on the industrial tank scaled-down model under changing external environmental conditions in the laboratory.

[0054] S103, stress test on the scaled-down model of the industrial tank is carried out according to the test conditions parameters of the scaled-down model.

[0055] It is understood that, in this embodiment of the present invention, stress testing of a scaled-down industrial tank model can be carried out in the laboratory according to the test conditions parameters of the scaled-down model, so that the scaled-down industrial tank model can achieve temperature-stress testing under changing external environmental conditions.

[0056] Furthermore, in some embodiments of the present invention, such as Figure 2 As shown, the test parameters for the scaled-down model are determined, including:

[0057] S201, replace the tank size in the first dimensionless parameter with the scaled-down model size, and adjust the test time to keep the first dimensionless parameter unchanged.

[0058] It is understood that, in this embodiment of the present invention, after replacing the tank size in the first dimensionless parameter with the scaled-down model size, the first dimensionless parameter can be kept unchanged by adjusting the test time in the first dimensionless parameter.

[0059] S202, replace the tank size in the second dimensionless parameter with the scaled-down model size, and adjust the test irradiation intensity value to keep the second dimensionless parameter unchanged.

[0060] It is understood that, in this embodiment of the present invention, after replacing the tank size in the second dimensionless parameter with the scaled-down model size, the second dimensionless parameter can be kept unchanged by adjusting the test irradiation intensity value in the second dimensionless parameter.

[0061] S203, replace the tank size in the third dimensionless parameter with the scaled-down model size, and adjust the experimental convective heat transfer coefficient to keep the third dimensionless parameter unchanged.

[0062] It is understood that, in this embodiment of the present invention, after replacing the tank size in the third dimensionless parameter with the scaled-down model size, the second dimensionless parameter can be kept unchanged by adjusting the experimental convective heat transfer coefficient in the third dimensionless parameter.

[0063] S204. Based on the adjusted test time, the adjusted test irradiance value, and the adjusted test convective heat transfer coefficient, the test parameters for the scaled-down model are determined.

[0064] It is understandable that thermal stress calculations are performed on a three-dimensional storage tank entity, and the three-dimensional thermal stress calculation expression using displacement and temperature is as follows:

[0065]

[0066] As can be seen from the above formula (6), as long as the temperature field is similar, the stress field is exactly the same. That is, in the scaled-down model test, the temperature field similar to that of the real tank is constructed according to the above formula (5). Then the stress test value of the scaled-down model test is the stress value generated by the real tank. Therefore, in this embodiment of the present invention, the adjusted test time, the adjusted test irradiance value and the adjusted test convective heat transfer coefficient can be determined as the scaled-down model test condition parameters required when the industrial tank scaled-down model is carried out.

[0067] Furthermore, in some embodiments of the present invention, such as Figure 3 As shown, the test time is adjusted to keep the first dimensionless parameter constant, including:

[0068] S301, after replacing the tank size in the first dimensionless parameter with the scaled-down model size, determine the scaling-down ratio of the actual tank size.

[0069] For example, in this embodiment of the invention, it is assumed that the first dimensionless parameter is... The scaled-down model is reduced in size by a factor of x compared to the actual tank. At this point... Then the reduction ratio of the actual tank size can be determined as follows:

[0070] S302, adjust the test time according to the reduction ratio of the actual tank size.

[0071] Furthermore, in this embodiment of the invention, the test time can be adjusted according to the reduction ratio of the actual tank size. For example, assuming the determined reduction ratio of the actual tank size is... The test time τ0 can then be adjusted to at this time, Keep the first dimensionless parameter unchanged.

[0072] Furthermore, in some embodiments of the present invention, such as Figure 4 As shown, the experimental irradiance value is adjusted to keep the second dimensionless parameter constant, including:

[0073] S401, after replacing the tank size in the second dimensionless parameter with the scaled-down model size, determine the scaling-down ratio of the actual tank size.

[0074] For example, in this embodiment of the invention, it is assumed that the second dimensionless parameter is The scaled-down model is reduced in size by a factor of x compared to the actual tank. At this point... Then the reduction ratio of the actual tank size can be determined as follows:

[0075] S402, adjust the test irradiation intensity value according to the reduction ratio of the actual tank size.

[0076] Furthermore, in this embodiment of the invention, the test irradiation intensity value can be adjusted according to the reduction ratio of the actual tank size. For example, assuming the determined reduction ratio of the actual tank size is... Then the experimental irradiation intensity value I0 can be adjusted to x*I0. At this time, This keeps the second dimensionless parameter unchanged.

[0077] Furthermore, in some embodiments of the present invention, such as Figure 5 As shown, the experimental convective heat transfer coefficient was adjusted to keep the third dimensionless parameter constant, including:

[0078] S501, after replacing the tank size in the third dimensionless parameter with the scaled-down model size, determine the scaling-down ratio of the actual tank size.

[0079] For example, in this embodiment of the invention, it is assumed that the third dimensionless parameter is... The scaled-down model is reduced in size by a factor of x compared to the actual tank. At this point... Then the reduction ratio of the actual tank size can be determined as follows:

[0080] S502, the experimental convective heat transfer coefficient is adjusted according to the reduction ratio of the actual tank size.

[0081] Furthermore, in this embodiment of the invention, the test irradiation intensity value can be adjusted according to the reduction ratio of the actual tank size. For example, assuming the determined reduction ratio of the actual tank size is... Then the experimental convective heat transfer coefficient h0 can be adjusted to x*h0. At this time, Keep the third dimensionless parameter unchanged.

[0082] It should be noted that, in some embodiments of the present invention, the experimental convective heat transfer coefficient is adjusted according to the following formula:

[0083] h0 = 6.5 + 3.3 * Va

[0084] Where Va is the fan speed.

[0085] It is understood that, in this embodiment of the present invention, the purpose of adjusting the test convective heat transfer coefficient can be achieved by adjusting the fan speed.

[0086] The following example, using Table 1 and a specific embodiment of this application, illustrates the testing process of the stress testing method for a scaled-down model of an industrial tank according to an embodiment of the present invention:

[0087] Table 1

[0088]

[0089] Based on Table 1 above, assuming the scaled-down industrial tank model is 5 times smaller than the actual tank, to keep the dimensionless parameters in the formula unchanged, the time τ0 for conducting the test on the actual tank needs to be reduced to the time for conducting the test on the scaled-down industrial tank model. The irradiance value I0 during the experiment on the actual tank is expanded to the irradiance value 5I0 during the experiment on the scaled-down industrial tank model. The convective heat transfer coefficient h0 during the experiment on the actual tank is also expanded to the convective heat transfer coefficient 5h0 during the experiment on the scaled-down industrial tank model. At this point, the test time can be... The temperature-stress test of a scaled-down industrial tank model under varying external environmental conditions was conducted in the laboratory with an irradiance value of 5I0 and a convective heat transfer coefficient of 5h0.

[0090] According to the stress testing method for a scaled-down industrial tank model of the present invention, the energy balance equation of the tank is dimensionless, and first, second, and third dimensionless parameters corresponding to the actual test conditions of the tank are constructed. Then, the scaled-down model dimensions are obtained, and the test conditions of the scaled-down model are determined based on the scaled-down model dimensions, the first, second, and third dimensionless parameters, and stress testing of the scaled-down industrial tank model is performed based on these test conditions. Thus, by using the first, second, and third dimensionless parameters corresponding to the actual test conditions of the tank, the test conditions of the scaled-down tank model corresponding to the scaled-down model dimensions are determined. This allows for temperature-stress testing of the scaled-down industrial tank model under varying external environmental conditions in the laboratory, reducing testing costs and providing data reference for the design of industrial tank structural parameters.

[0091] Based on the stress testing method of the scaled-down industrial tank model according to the above embodiments of the present invention, the present invention also proposes a computer-readable storage medium storing a stress testing program of the scaled-down industrial tank model thereon. When the stress testing program of the scaled-down industrial tank model is executed by a processor, the stress testing method of the scaled-down industrial tank model according to the above embodiments of the present invention is implemented.

[0092] It should be understood that when executing the stress testing program for the scaled-down industrial tank model stored on the computer-readable storage medium of the present invention, specific implementation methods corresponding one-to-one with the stress testing methods for the scaled-down industrial tank model of the aforementioned present invention can be realized. To reduce redundancy, these will not be described again here.

[0093] In summary, according to the computer-readable storage medium of the present invention, by executing the stress test program of the scaled-down industrial tank model stored thereon through a processor, temperature-stress tests of the scaled-down industrial tank model under changing external environmental conditions can be carried out in the laboratory, reducing testing costs and providing data reference for the design of industrial tank structural parameters.

[0102] Furthermore, in some embodiments of the present invention, the determining module 20 is also used to adjust the experimental convective heat transfer coefficient according to the following formula: h0=6.5+3.3*Va, where Va is the fan speed.

[0103] It should be understood that the specific implementation of the stress testing device for the scaled-down industrial tank model in this embodiment of the invention corresponds one-to-one with the specific implementation of the stress testing method for the scaled-down industrial tank model in the aforementioned embodiment of the invention. To reduce redundancy, it will not be described again here.

[0104] The stress testing device for a scaled-down industrial tank model according to an embodiment of the present invention uses a construction module to make the tank's energy balance equation dimensionless and constructs a first dimensionless parameter, a second dimensionless parameter, and a third dimensionless parameter corresponding to the actual tank test conditions. Then, a determination module obtains the scaled-down model dimensions, and based on the scaled-down model dimensions, the first dimensionless parameter, the second dimensionless parameter, and the third dimensionless parameter, determines the scaled-down model test conditions. Finally, a testing module performs stress testing on the scaled-down industrial tank model based on the scaled-down model test conditions. Thus, by using the first dimensionless parameter, the second dimensionless parameter, and the third dimensionless parameter corresponding to the actual tank test conditions, the test conditions of the scaled-down tank model corresponding to the scaled-down model dimensions are determined. This allows for temperature-stress testing of the scaled-down industrial tank model under varying external environmental conditions in the laboratory, reducing testing costs and providing data reference for the design of industrial tank structural parameters.
