Description

Technical Field

[0001] This application relates to the field of marine technology, and more specifically, to a method, system, computer storage medium, and device for verifying and optimizing marine portal frame tube beams. Background Technology

[0002] The descriptions in this section are provided only as background information in connection with this disclosure and may not constitute prior art.

[0003] Ship piping is mainly connected to the hull structure via supports and hangers to secure the piping system, including portal frames such as... Figure 1 As shown, this type of support, also known as a gantry frame, portal frame, or portal support bracket, consists of a pipe support beam 1 and a pipe support column 2, with pipes 3 installed on the pipe support beam 1. This type of support has good mechanical properties and is widely used. Currently, there are no standards for the structural parameters of portal frames in the shipbuilding industry. Engineering practice often relies on empirical methods, determining portal frame parameters based on a single parameter (pipe diameter) or two parameters (pipe diameter and support height). This leads to a conservative stress state for the portal frame, resulting in the total weight of the ship's pipe support system far exceeding the actual required weight. This conservative design of pipe supports significantly increases the ship's weight, making it difficult to meet the requirements for lightweight ship construction.

[0004] Currently, in the ship design process, for subsequent "sister ship" designs with identical overall structures or subsequent newbuild designs with similar overall structures, adjustments and verifications are typically made based on an existing 3D ship model. This greatly improves ship design efficiency. However, regardless of whether it's a subsequent "sister ship" or a subsequent newbuild, the lack of lightweight design methods for portal frame supports, coupled with the large number of portal frame supports in the 3D model and the heavy workload, makes it difficult to carry out lightweight portal frame support design work for subsequent "sister ships" and subsequent newbuilds. Furthermore, the current method of manually searching for experience to determine support parameters for portal frame supports requires switching modeling interfaces, severely impacting the modeling efficiency of designers and easily leading to parameter setting errors. The parallel construction method for series ships will introduce these errors into the construction of subsequent "sister ships" and subsequent newbuilds, significantly increasing the rate of pipework scrap and slowing down the shipbuilding cycle. Summary of the Invention

[0005] The purpose of this application is to provide a method for verifying and optimizing the portal frame tube beam of a ship, which can improve the efficiency of verifying the model of the portal frame tube beam in a three-dimensional pipeline model.

[0006] Another objective of this application is to provide a marine portal frame tube beam verification and optimization system for implementing the above-described marine portal frame tube beam verification and optimization method; to provide a computer storage medium for implementing the above-described marine portal frame tube beam verification and optimization method; and to provide a computer device for implementing the above-described marine portal frame tube beam verification and optimization method.

[0007] Firstly, a method for verifying and optimizing marine portal frame tube beams is provided, including the following steps:

[0008] 1) Import the 3D pipeline model to be checked and optimized into the 3D modeling platform, and define the non-geometric parameters of the 3D pipeline model; the non-geometric parameters of the 3D pipeline model include the pipe rack beam profile type;

[0009] 2) Construct and call the function to look up the empirical parameter library of pipe rack beams. The function is to retrieve the profile model of the pipe rack beam from the empirical design parameter library of pipe rack beams under the condition that the geometric parameters of the three-dimensional pipeline model are known.

[0010] 3) Compare the pipe rack beam profile model in the 3D pipeline model to be checked and optimized with the pipe rack beam profile model obtained from the pipe rack beam experience design database in step 2). If the two are inconsistent, save the pipe rack beam profile model obtained from the pipe rack beam experience design database and mark the pipe rack beam for subsequent processing by the designer; if the two are consistent, proceed to the next step.

[0011] 4) Construct a function to call the physical property library of the calculation method. The function is to retrieve the physical property parameters in the physical property library corresponding to the three-dimensional pipeline model parameters given the parameters of the three-dimensional pipeline model.

[0012] Construct a function to call the parameter library of pipe rack beam profiles. The function's purpose is to retrieve the corresponding model of the pipe rack beam profile given its geometric parameters.

[0013] 5) Call the physical property library function of the calculation method in step 4) to solve for the vertical and horizontal loads of the pipeline support;

[0014] 6) Call the physical property library call function of the calculation method in step 4), and calculate the shear strength and bending strength that the pipe rack beam needs to meet based on the vertical load and horizontal load of the pipe support in step 5). Call the pipe rack beam profile parameter library call function and the physical property library call function of the calculation method in step 4) to obtain the pipe rack beam profile model that meets the shear strength and bending strength.

[0015] 7) Compare the pipe rack beam profile model in the 3D pipeline model to be checked and optimized with the pipe rack beam profile model calculated in step 6). If the size of the pipe rack beam profile model in the 3D pipeline model to be checked and optimized is smaller, the model of the pipe rack beam profile in the 3D pipeline model to be checked and optimized will not be changed and no marking will be performed; if the size of the pipe rack beam profile model calculated in step 6) is smaller, store the calculation result of step 6) and mark the pipe rack beam for subsequent processing by the designer.

[0016] In one possible implementation, the tube frame beam is marked with color in step 3), and the tube frame beam is marked with a different color in step 7).

[0017] In one possible implementation, step 6) includes:

[0018] Step 61): Call the physical property library call function and the pipe rack beam profile parameter library call function from step 4) to calculate the model of the pipe rack beam profile that meets the shear strength requirements;

[0019] Step 62): Call the physical property library function of the calculation method in Step 4). Based on the solution in Step 61), calculate the bending strength of the pipe rack beam profile calculated in Step 61). If the bending strength of the pipe rack beam profile does not meet the requirements, increase the size of the pipe rack beam profile until the bending strength of the pipe rack beam profile meets the requirements. At this time, the model of the pipe rack beam profile obtained by calling the parameter library function is the model of the pipe rack beam profile that meets the requirements of shear strength and bending strength.

[0020] In one possible implementation, the process for determining the profile type of the pipe rack beam in step 61) is as follows:

[0021]

[0022] In the formula, S: cross-sectional area of ​​the pipe rack beam;

[0023] α: Load factor;

[0025] T H The maximum shear force in the horizontal direction that a pipe rack beam bears under horizontal load;

[0026] n s Safety factor;

[0027] τ: Allowable shear stress of the pipe;

[0028] After solving, obtain the minimum cross-sectional area S of the pipe rack beam profile that meets the shear strength requirement. Call the pipe rack beam profile parameter library call function in step 4) to find and obtain the model of the pipe rack beam profile that meets the shear strength requirement.

[0029] In one possible implementation, in step 62), when the pipe rack beam profile satisfies the inequality for solving the bending strength of the pipe rack beam, the bending strength of the pipe rack beam profile meets the requirement. The inequality for solving the bending strength of the pipe rack beam is:

[0030]

[0031] In the formula, α: load factor;

[0032] M V : Maximum bending moment of the pipe rack beam section under vertical load;

[0033] M H : Maximum bending moment of the pipe rack beam section under horizontal load;

[0034] r V r H M V M H The cross-sectional plastic development coefficient corresponding to the direction;

[0035] W nV W nH M V M H Section modulus corresponding to the direction;

[0036] n s Safety factor;

[0037] σ: Allowable stress of the pipe.

[0038] In one possible implementation, in step 1), the insulation material thickness parameters and insulation material parameters of the three-dimensional pipeline model are input, and in step 5), the parameters for calculating the vertical load include the weight of the insulation material.

[0039] Secondly, a verification and optimization system for marine portal frame tube beams is provided, including:

[0040] The definition module is used to supplement the definition of non-geometric parameters of the 3D pipeline model in the 3D modeling platform;

[0041] The verification module is used to build and call the lookup function of the pipe rack beam experience parameter library to obtain the pipe rack beam profile model in the pipe rack beam experience design parameter library;

[0042] The optimization module is used to build functions for calling the physical property library of calculation methods, functions for calling the parameter library of pipe rack beams, solve for the vertical and horizontal loads of pipe supports, and solve for the pipe rack beam profile types that meet the shear strength and bending strength requirements.

[0043] The tagging and storage module is used to store the verification and optimization results of the pipe rack beam profile and to tag the target pipe rack beam;

[0044] The judgment module compares the pipe rack beam profile model in the 3D modeling platform with the pipe rack beam profile model found in the pipe rack beam experience design database. If the results are consistent, the module proceeds to the optimization module for optimization. If the results are inconsistent, the pipe rack beam is marked by the marking and storage module, and the pipe rack beam profile model found in the pipe rack beam experience design database is stored. The module also compares the pipe rack beam model in the 3D modeling platform with the mathematical calculation results, selects the smaller pipe rack beam model, marks it by the marking and storage module, and stores it.

[0045] Thirdly, a computer storage medium is provided that stores a computer program, which, when executed by a processor, implements the marine portal frame tube beam verification and optimization method described in any embodiment of the first aspect.

[0046] Fourthly, a computer device is provided, comprising:

[0047] Memory and processor

[0048] The memory stores a computer program that, when executed by a processor, implements the marine portal frame tube girder verification and optimization method described in any embodiment of the first aspect.

[0049] The beneficial effects of the verification and optimization method for marine portal frame tube beams in this application are as follows: The method imports the three-dimensional pipeline model to be verified and optimized into a three-dimensional modeling platform. It then uses a lookup function from the tube beam empirical parameter library to retrieve the tube beam profile model and compares it with the tube beam model in the three-dimensional pipeline model. If they are inconsistent, they are marked for subsequent processing by the designer. If they are consistent, the minimum size of the tube beam is calculated based on the non-geometric parameters of the three-dimensional pipeline model, and the result is stored and marked for optimization by the designer. This verification and optimization method verifies the tube beam design by constructing a lookup function from the tube beam empirical parameter library to determine if there are any unconventional designs or design errors. If it is a normal empirical design, the optimization result of the tube beam can be obtained by calculating the minimum size of the tube beam for subsequent processing by the designer. Compared with manual verification through lookup and calculation, this verification and optimization method is more efficient and considers non-geometric parameters when calculating the tube beam model, resulting in more accurate results.

[0054] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0055] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0056] According to the first aspect of this application, a method for verification and optimization of marine portal frame tube beams is provided. Figure 2 This is a flowchart illustrating a method for verifying and optimizing a marine portal frame tube beam according to an embodiment of this application.

[0057] The verification and optimization method for marine portal frame tube beams includes the following steps:

[0058] 1) Import the three-dimensional pipeline model to be checked and optimized into the three-dimensional modeling platform, and supplement the definition of the non-geometric parameters of the three-dimensional pipeline model; the three-dimensional pipeline model of this application includes the pipeline model and the pipeline support model.

[0059] 2) Construct and call the function to look up the empirical parameter library of pipe rack beams. The function is to retrieve the profile type of pipe rack beam from the empirical design parameter library of pipe rack beams under the condition that the geometric parameters of the three-dimensional pipeline model are known. The parameters of the three-dimensional pipeline model can include parameters such as pipe diameter and support height.

[0060] 3) Compare the pipe rack beam profile model in the 3D pipeline model to be verified and optimized with the pipe rack beam profile model obtained from the pipe rack beam experience design database in step 2). If the two are inconsistent, save the pipe rack beam profile model obtained from the pipe rack beam experience design database and mark the pipe rack beam for designers to verify the pipe rack beam profile model in the 3D pipeline model later. If the two are consistent, proceed to the next step.

[0061] 4) Construct a function to call the physical property library of the calculation method. The function is to retrieve the physical property parameters in the physical property library corresponding to the three-dimensional pipeline model parameters given the parameters of the three-dimensional pipeline model.

[0062] Non-geometric parameters include operating conditions, the fluid flowing inside the pipe, and the pipe material. The physical property libraries corresponding to the parameters of the three-dimensional pipe model include fluid medium physical property libraries and pipe material physical property libraries.

[0063] Construct a function to call the parameter library of pipe rack beam profiles. The function's purpose is to retrieve the corresponding model of the pipe rack beam profile given its geometric parameters.

[0064] 5) Call the physical property library function of the calculation method in step 4) to solve for the vertical and horizontal loads of the pipeline support.

[0065] 6) Call the physical property library call function of the calculation method in step 4), and calculate the shear strength and bending strength that the pipe rack beam needs to meet based on the vertical load and horizontal load of the pipe support in step 5). Call the pipe rack beam profile parameter library call function and the physical property library call function of the calculation method in step 4) to obtain the pipe rack beam profile model that meets the shear strength and bending strength.

[0066] 7) At this point, both the pipe rack beam profile model in the 3D piping model and the pipe rack beam profile model calculated in step 6) meet the usage requirements. Comparing the pipe rack beam profile model in the 3D piping model to be checked and optimized with the pipe rack beam profile model calculated in step 6), if the size of the pipe rack beam profile model in the 3D piping model to be checked and optimized is smaller, then the pipe rack beam profile model in the 3D piping model to be checked and optimized will not be changed and will not be marked; if the size of the pipe rack beam profile model calculated in step 6) is smaller, the calculation results of step 6) will be stored and the pipe rack beam will be marked for designers to use as a reference for subsequent optimization.

[0067] In this application, the constructed physical property library includes non-geometric parameters and physical property parameters of the 3D pipeline model; the constructed pipe rack beam profile parameter library includes geometric parameters and models of pipe rack beam profiles; and the constructed pipe rack beam empirical design database includes 3D pipeline model parameters and pipe rack beam profile models, where the 3D pipeline model parameters are geometric parameters. It should be noted that different databases cover different types of data. Comparatively, the physical property library corresponding to the physical property library call function of the calculation method contains a wider variety of data.

[0068] The data in each database includes both input condition data for calling functions and output result data of the calling functions based on the input conditions. For example, the physical property library contains non-geometric parameter data of three-dimensional pipeline models, as well as physical property parameters obtained by calling functions from the physical property library through calculation methods.

[0069] The verification and optimization method proposed in this application is for automated verification and optimization of portal frame supports for newly built ships or subsequent "sister ships" based on existing 3D ship models. Typically, the 3D piping models of existing ship models are designed based on experience. By importing the 3D piping model to be verified and optimized into a 3D modeling platform, the model number of the portal frame beam profile is retrieved using a lookup function from the portal frame beam experience parameter library. This model is then compared with the portal frame beam model number in the 3D piping model. If they do not match, they are marked for designers to verify whether there is a design error. If they match, the minimum size of the portal frame beam is calculated based on the non-geometric parameters of the 3D piping model, and the results are stored and marked for designers to use as an optimization reference. The verification and optimization method of this application verifies the design of the pipe rack beam by constructing an empirical parameter library and searching for functions to determine whether there are any unconventional designs or design errors. If it belongs to a normal empirical design, the optimization result of the pipe rack beam can be obtained by calculating the minimum size of the pipe rack beam, which can be used by designers for subsequent processing. Compared with the verification method by manual search and calculation, the verification and optimization method of this application is more efficient, and the non-geometric parameters are considered when calculating the pipe rack beam model, resulting in more accurate results.

[0074] Step 62): Call the physical property library function of the calculation method in Step 4). Based on the solution in Step 61), calculate the bending strength of the pipe rack beam profile calculated in Step 61). If the bending strength of the pipe rack beam profile does not meet the requirements, increase the size of the pipe rack beam profile until the bending strength of the pipe rack beam profile meets the requirements. At this time, the model of the pipe rack beam profile obtained by calling the parameter library function is the model of the pipe rack beam profile that meets the requirements of shear strength and bending strength.

[0075] In one embodiment, the process of determining the model of the pipe rack beam profile in step 61) is as follows:

[0084] After solving, obtain the minimum cross-sectional area S of the pipe rack beam profile that meets the shear strength requirement. Call the pipe rack beam profile parameter library call function in step 4) to find and obtain the model of the pipe rack beam profile that meets the shear strength requirement.

[0085] In one embodiment, in step 62), when the pipe rack beam profile satisfies the inequality for solving the bending strength of the pipe rack beam, the bending strength of the pipe rack beam profile meets the requirements. The inequality for solving the bending strength of the pipe rack beam is:

[0086]

[0087] In the formula, α: load factor, with a reference range of 1.2-2.0;

[0091] W nV W nH M V M H Section modulus corresponding to the direction;

[0092] n s Safety factor, reference range 0.5-0.9;

[0093] σ: Allowable stress of the pipe;

[0094] Among them, the load factor α and the safety factor n s An input window is provided, which users can customize according to their design requirements.

[0095] In one embodiment, step 1) inputs the insulation material thickness parameters and insulation material parameters of the three-dimensional pipeline model, and step 5) calculates the parameters for the vertical load, including the weight of the insulation material. This makes the calculated vertical load result closer to the actual value. The non-geometric parameters include the insulation material thickness and insulation material, and the corresponding physical property libraries for the three-dimensional pipeline model parameters include a physical property library for insulation material thickness and a physical property library for insulation material.

[0096] In one possible implementation, step 5) further includes calculating the parameters for the vertical load, including the weight of the pipe, the weight of the insulation material, and the additional weight; the calculation process for each part of the weight is as follows:

[0097] C c =gρ G nδ G (D-δ G )L

[0098] G B =gρ B πδ B (D+δ B )L

[0099]

[0100] In the formula, GG Pipe weight; ρ G Pipe density;

Firstly, it analyzes the tube beam design method from the perspectives of engineering mechanics and mathematics, systematically considering the influence of multiple parameters such as pipeline geometry, internal media, pipeline material, and insulation material on the tube beam. Secondly, by combining the design standards and guidelines for shipbuilding supports and hangers, it demonstrates that traditional design methods can significantly reduce the overall weight of the ship's piping system, achieving the design goal of lightweighting the ship. Simultaneously, this application's method fully utilizes computer-aided design functions, automatically verifying and optimizing the tube beam profile type in the 3D model after the piping support and hanger model is completed for subsequent new ships or "sister ships." For large ocean-going vessels, this application can improve the modeling efficiency of the ship's piping system and shorten the shipbuilding cycle, while ensuring the stability of the ship's piping.
