Description

Technical Field

[0001] The present application relates to the technical field of container manufacturing, and in particular to a simulation method, device, equipment and storage medium for a temperature-resistant and deformable refrigerated container. Background Art

[0002] As a core component of the modern logistics system, containers have a very broad development prospect. During the transportation process, especially during sea transportation, containers face complex climate environments, such as sun exposure, rain and snow.

[0003] The goods inside the container need to meet the storage temperature conditions. The container is equipped with an insulation layer to provide a constant temperature inside the container. However, under the condition of sun exposure or snow and rain, the temperature difference between the inside and outside of the container increases, causing the top surface of the container to deform and arch during transportation (the top surface is directly exposed to the sun, and the temperature difference between the inside and outside is mainly between the top of the container and the inside), and the container body and the insulation layer are debonded. Therefore, the temperature deformation resistance of the container is very important.

[0004] In related technologies, the design of container products is mostly based on stiffness algorithms and design experience, leaving a large safety margin. It is difficult to predict the positions prone to deformation during actual use, resulting in high design costs and long design cycles. Summary of the invention

[0051] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of this application.

[0052] As a core component of the modern logistics system, containers have a very broad development prospect. During the transportation process, especially during sea transportation, containers face complex climate environments, such as sun exposure, rain and snow.

[0053] The goods inside the container need to meet the storage temperature conditions. The container is equipped with an insulation layer to provide a constant temperature inside the container. However, under the condition of sun exposure or snow and rain, the temperature difference between the inside and outside of the container increases, causing the top surface of the container to deform and arch during transportation (the top surface is directly exposed to the sun, and the temperature difference between the inside and outside is mainly between the top of the container and the inside), and the container body and the insulation layer are debonded. Therefore, the temperature deformation resistance of the container is very important.

[0054] In related technologies, the design of container products is mostly based on stiffness algorithms and design experience, leaving a large safety margin. It is difficult to predict the positions prone to deformation during actual use, resulting in high design costs and long design cycles.

[0055] The present application provides a method, device, equipment and storage medium for simulating a temperature-deformation-resistant refrigerated container to solve or improve the problems of high design cost and long design cycle.

[0056] Combine the following Figures 1 to 9 , describing an embodiment of the present application.

[0057] According to an embodiment of the present application, on the one hand, a simulation method for a temperature-resistant deformation refrigerated container is provided, which is applied to a simulation software. Specifically, the simulation software is a finite element software, such as Figure 1 As shown, the method includes:

[0058] Step S101: obtaining a three-dimensional solid model of a container, wherein a reinforcing profile 1 is provided in a top area of ​​the three-dimensional solid model.

[0059] Specifically, Figure 2 As shown, the three-dimensional solid model of the container can be directly imported into the finite element software, or the three-dimensional solid model of the container can be directly modeled in the finite element software. Generally, the former is adopted.

[0060] Step S102: configuring the temperature field constraints and load constraints of the three-dimensional solid model.

[0061] Step S103: Start the simulation to obtain the mechanical performance parameters of the top area of ​​the three-dimensional solid model.

[0062] It should be noted that in this embodiment, finite element software is used for simulation, and the top area of ​​the three-dimensional solid model of the container needs to be gridded. The number of grids can be selected and set according to the size and type of the container.

[0063] Specifically, when performing mesh division, the size of the mesh adopts a hexahedral mesh with a side length of 1 mm to 10 mm.

[0064] Specifically, the mechanical performance parameters of the top area can be expressed as a strain cloud map, a stress cloud map, or a displacement cloud map, or by dividing the top of the three-dimensional solid model of the container into regions and outputting the corresponding mechanical performance parameters of the top area according to the divided regions, or other methods can be used.

[0065] Step S104: Determine whether the mechanical performance parameters of each part of the box top area meet the preset standards.

[0066] Step S105 : if at least one part does not meet the preset standard, adjusting the structural parameters of the part that does not meet the preset standard, wherein the structural parameters include the design parameters of the reinforcing profile 1 .

[0067] Step S106: simulating the adjusted three-dimensional solid model again until the mechanical performance parameters of each part of the box top area meet the preset standards.

[0068] Specifically, the mechanical performance parameters include strain parameters, stress parameters and displacement parameters.

[0069] In this embodiment, under the conditions of configuring temperature field constraints and load constraints, the simulation software simulates the stress conditions of the three-dimensional solid model of the container, thereby simulating the mechanical performance parameters of the top area of ​​the container, and judging whether the mechanical performance parameters of each part of the top area meet the preset standards. When the mechanical performance parameters of each part of the top area meet the preset standards, the design parameters of the reinforcing profile 1 in the three-dimensional solid model of the container are output.

[0070] When at least one part does not meet the preset standards, the structural parameters of the part that does not meet the preset standards are adjusted, and the adjusted three-dimensional solid model is simulated again under the conditions of configuring temperature field constraints and load constraints until the mechanical performance parameters of the box top area meet the preset standards.

[0071] Through the above method, the design cost of the container can be reduced and the design cycle can be shortened, while the mechanical strength of the container can be made to meet daily use.

[0072] In one embodiment, configuring the temperature field constraints of the three-dimensional solid model includes: configuring temperature parameters on the outer side and inside of the three-dimensional solid model.

[0073] Specifically, the temperature field of the top area of ​​the three-dimensional solid model of the container is configured to be 80°C to 120°C, the temperature field of the bottom area is 40°C to 50°C, the temperature field of the outer side area is 50°C to 80°C, and the temperature field of the inner area of ​​the box is 30°C to 50°C. The above temperature field constraints are applied to the finite element model of the three-dimensional solid model of the container, and the finite element thermal analysis is performed to obtain the following: Figure 3 The temperature field distribution of the top area of ​​the container is shown, which is mapped to the 3D solid model of the container as the temperature field constraint for subsequent mechanical properties analysis.

[0074] In one embodiment, configuring the load constraint of the three-dimensional solid model includes: applying loads to the outer side surface and the bottom surface of the three-dimensional solid model to constrain the three-dimensional solid model.

[0075] In this embodiment, loads are applied to the outer side and bottom of the container to constrain the three-dimensional solid model and prevent the bottom and sides from deforming, so that the deformation of the top area of ​​the container can be analyzed.

[0076] Specifically, finite element software is used to simulate the load constraints when the bottom and sides of the containers are squeezed when they are stacked.

[0077] In one embodiment, the structural parameters include the design parameters of the reinforcing profile 1 and also include the number of the reinforcing profile 1 , the position of the reinforcing profile 1 , and the cross-sectional shape and thickness of the reinforcing profile 1 .

[0078] Specifically, Figure 4As shown, reinforcing profiles 1 are added to the top area of ​​the three-dimensional solid model of the container by using finite element software. The number of reinforcing profiles 1 is 9 to 11, which can be any one of 9, 10 and 11.

[0079] Specifically, the reinforcing profile 1 is made of aluminum alloy.

[0080] Specifically, Figure 4 As shown, a reinforcing profile 1 is added to the top area of ​​the three-dimensional solid model of the container by using finite element software, and the reinforcing profile 1 is distributed on the outside and inside of the top area.

[0081] Specifically, Figure 4 As shown, the reinforcing profile 1 includes a short reinforcing profile 102 and a long reinforcing profile 101 . The short reinforcing profile 102 is arranged on the inner side of the box top area, and the long reinforcing profile 101 is arranged on the outer side of the box top area.

[0082] Specifically, Figure 4 As shown, 10 long reinforcing profiles 101 are arranged on the outer surface of the box top area, and 11 short reinforcing profiles 102 are arranged on the inner surface of the box top area.

[0083] It should be noted that if Figure 4 As shown, 10 long reinforcing profiles 101 and 11 short reinforcing profiles 102 are staggeredly arranged.

[0084] Specifically, the cross section of the reinforcing profile 1 is an “I” shape or an “Ω” shape.

[0085] In embodiment A, the cross-sections of the long reinforcing profiles 101 and the short reinforcing profiles 102 are both "Ω" shaped. Ten long reinforcing profiles 101 are arranged on the outer surface of the top area of ​​the box, and eleven short reinforcing profiles 102 are arranged on the inner surface of the top area of ​​the box.

[0086] In embodiment B, the cross-sections of the long reinforcing profiles 101 and the short reinforcing profiles 102 are both "Ω" shaped. Ten long reinforcing profiles 101 are arranged on the outer surface of the top area of ​​the box, and nine short reinforcing profiles 102 are arranged on the inner surface of the top area of ​​the box.

[0087] In Example C, the cross-sections of the long reinforcing profiles 101 and the short reinforcing profiles 102 are both in the shape of an I. Ten long reinforcing profiles 101 are arranged on the outer surface of the top area of ​​the box, and 11 short reinforcing profiles 102 are arranged on the inner surface of the top area of ​​the box.

[0088] By setting the cross section and quantity of the reinforcing profile 1 and performing simulation analysis, the data of the maximum displacement, maximum stress, maximum strain and container mass of the container top area are obtained, as shown in the table:

[0089]

[0090] like Figure 5 As shown in the figure, through finite element software analysis, the stress cloud diagram of the top area of ​​the box is ≤100MPa; Figure 6 As shown, the maximum strain in the box top area is 1.65%, which is less than 3% and meets the preset standard.

[0091] In one embodiment, the structural parameters include the design parameters of the reinforcing profile 1 and also include the width of the welding area of ​​the box top area.

[0092] The welding area is a weak area and needs to be calculated for cumulative damage. Setting a 20mm width area in the welding area can improve the mechanical strength of the box top area.

[0093] In one embodiment, the structural parameters include the design parameters of the reinforcement profile 1 and also include the thicknesses of the outer surface layer 2 , the core layer 3 and the inner surface layer 4 in the roof area.

[0094] Specifically, the top of the three-dimensional solid model of the container includes: an outer surface layer 2, a core layer 3 and an inner surface layer 4, and the core layer 3 is connected to the outer surface layer 2 and the inner surface layer 4 by gluing.

[0095] Specifically, the outer surface layer 2 is an aluminum plate, the core layer 3 is a polyurethane insulation board, and the inner surface layer 4 is an FPR board. Using finite element software, the aluminum plate, the polyurethane insulation board and the FPR board are connected through bonding units, simulating the bonding of the polyurethane insulation board to the aluminum plate and the FPR board by glue injection. When performing finite element simulation, the bonding unit is used to calculate the debonding between the polyurethane insulation board, the aluminum plate and the FPR board. Under the condition of temperature field constraints, the bonding unit in the top area of ​​the container fails, and the polyurethane insulation board, the aluminum plate and the FPR board are debonded. The deformation of the area here exceeds the preset standard, and the thickness of the outer surface layer 2, the core layer 3 and the inner surface layer 4 needs to be adjusted.

[0096] Specifically, finite element software is used to perform solid mesh division on the three-dimensional solid model of the temperature-resistant deformation refrigerated container. According to the size of the three-dimensional solid model, the outer surface layer 2 is divided into a first-order hexahedral mesh with a size of 10 mm, the inner surface layer 4 is divided into a first-order hexahedral mesh with a size of 10 mm, the core layer 3 is divided into a first-order hexahedral mesh with a size of 10 mm, and the reinforcing profile 1 is divided into a first-order hexahedral mesh with a size of 1 mm to generate a finite element model of the container.

[0097] When the mechanical performance structure of the three-dimensional solid model of the container obtained through finite element analysis does not meet the above preset standards, the number, position, cross-sectional shape, thickness of the reinforcing profile 1, and the thickness of the outer surface layer 2, the core layer 3 and the inner surface layer 4 in the top area of ​​the box are adjusted.

[0098] Taking the outer surface layer 2 as an example, Figure 3 and Figure 7 As shown, after completing the configuration of the temperature field constraints and load constraints of the three-dimensional solid model, finite element analysis is performed. The degree of deformation of various parts of the container is different. The overall deformation is between 0-8.035mm. The maximum displacement of the outer surface layer 2 is 8.035mm, which occurs in the top area of ​​the container. Therefore, the design is mainly focused on the top area of ​​the container.

[0099] Embodiment D, the thickness of the outer surface layer 2, the thickness of the core layer 3 and the thickness of the inner surface layer 4 are adjusted, the thickness of the outer surface layer 2 is 1.5mm, the thickness of the inner surface layer 4 is 1.5mm, the thickness of the core layer 3 is 91.5mm, the cross section is an "Ω"-shaped reinforcement profile 1, and the thickness is 2.5mm. Figure 4 As shown, the finite element model of the top area of ​​the container is obtained according to the adjusted design parameters.

[0100] Embodiment E, the thickness of the outer surface layer 2, the thickness of the core layer 3 and the thickness of the inner surface layer 4 are adjusted, the thickness of the outer surface layer 2 is 2mm, the thickness of the inner surface layer 4 is 1.5mm, the thickness of the core layer 3 is 91.5mm, the cross section is an "Ω"-shaped reinforcement profile 1, and the thickness is 2.5mm. Figure 4 As shown, the finite element model of the top area of ​​the container is obtained according to the adjusted design parameters.

[0101] Embodiment F, the thickness of the outer surface layer 2, the thickness of the core layer 3 and the thickness of the inner surface layer 4 are adjusted, the thickness of the outer surface layer 2 is 1.5mm, the thickness of the inner surface layer 4 is 1.5mm, the thickness of the core layer 3 is 90mm, the cross section is an "Ω"-shaped reinforcement profile 1, and the thickness is 2.5mm. Figure 4 As shown, the finite element model of the top area of ​​the container is obtained according to the adjusted design parameters.

[0102] According to the design parameter adjustment in Example D, Example E and Example F, the maximum displacement of the outer surface layer 2 in the box top area, the maximum stress of the reinforcing profile 1 and the maximum strain data of the outer surface layer 2 are shown in the following table:

[0103]

[0104] It should be noted that the results obtained in the above embodiments all meet the preset standards.

[0105] According to an embodiment of the present application, on the other hand, a temperature-resistant deformation refrigerated container simulation device is provided, the device comprising:

[0106] The acquisition module 100 is used to acquire a three-dimensional solid model of a container; wherein a reinforcement profile 1 is provided in the top area of ​​the container;

[0107] Configuration module 200, used to configure temperature field constraints and load constraints of the three-dimensional solid model;

[0108] The simulation module 300 is used to obtain the mechanical performance parameters of the top area of ​​the three-dimensional solid model;

[0109] The judging module 400 is used to judge whether the mechanical performance parameters of each part of the box top area meet the preset standards;

[0111] The adjustment module 500 is connected to the simulation module 300, and the adjusted three-dimensional solid model is simulated again until the mechanical performance parameters of each part of the box top area meet the preset standards.

[0112] In this embodiment, the acquisition module 100 acquires the three-dimensional solid model of the container, the configuration module 200 applies temperature field constraints and load constraints on the three-dimensional solid model of the container, and the simulation module 300 simulates the stress conditions of the three-dimensional solid model of the container, thereby simulating the mechanical performance parameters of the top area of ​​the container, and judging whether the mechanical performance parameters of each part of the top area meet the preset standards. When the mechanical performance parameters of each part of the top area meet the preset standards, the design parameters of the reinforcing profile 1 in the three-dimensional solid model of the container are output.

[0113] When at least one part does not meet the preset standard, the structural parameters of the part that does not meet the preset standard are adjusted, and the adjusted three-dimensional solid model is simulated again under the conditions of configuring temperature field constraints and load constraints until the mechanical performance parameters of the top area meet the preset standards. This can reduce the design cost of the container and shorten the design cycle, while making the mechanical strength of the container meet daily use.

This corresponds to step S103 in the above method.

[0129] Step 4: Determine whether the mechanical performance parameters of each part of the top area of ​​the box meet the preset standards. This corresponds to step S104 in the above method.
