Abstract
Description
Technical Field
[0001] The present disclosure relates to the technical field of ship structure design, and in particular to a variable height beam structure design method, system, electronic equipment and medium for a ship. Background Art
[0002] At present, in the design of large ships, there are a large number of wind ducts, pipelines and cables at the bottom of each deck, which puts forward extremely high requirements on the utilization rate of the limited upper space below the deck. The traditional lightening hole design can no longer meet the perforation requirements of wind ducts, pipelines and cables, and too large lightening holes will lead to reduced structural strength. Therefore, it is considered to design a variable height beam structure, such as Figure 1 As shown. At present, in the traditional design of variable height beam structures of ship decks, designers determine the height of the web of the variable height beam according to the layout requirements of large air ducts, pipelines, cables, etc., and determine the thickness of the web and the specifications of the panel based on design experience to ensure that the section modulus of the variable height beam under equal cross-section is not less than that of the ordinary deck strong beam. Then, a model of the variable height beam and the deck on which it is located is established, and the local structural strength calculation is performed. According to the calculated structure, it is judged whether the design of the variable height beam structure meets the requirements of the classification society specifications. However, such a design process lacks data support in the variable height beam selection stage, and the selection is made only based on the experience of the designers.

[0062] Example 1
[0063] This embodiment provides a variable height beam structure design method for a ship, which is applied to the Apex software platform (a process simulation software suitable for the entire life cycle of engineering design, factory production, education and scientific research in process industries). Figure 2 , the design method of variable height beam structure of ship includes:
[0064] S1. Determine a first parameter range.
[0065] The first parameter range includes a panel thickness range of the variable height beam structure, a panel width range of the variable height beam structure, and a web thickness range of the variable height beam structure.
[0066] S2. Determine a plurality of variable height beam structures according to the second parameter value and the first parameter range.
[0067] Among them, the second parameter value includes the cross-sectional area of the original equal-height beam structure and the section modulus of the original equal-height beam structure.
[0068] In an optional embodiment, step S2 includes:
[0069] S21. Determine several variable height beam structures through genetic algorithm.
[0070] The initial population of the genetic algorithm is determined according to the first parameter range, and the fitness function of the genetic algorithm is determined according to the second parameter value.
[0071] S3. Determine the target variable height beam structure.
[0072] The target variable height beam structure is a variable height beam structure with the smallest structural weight among the plurality of variable height beam structures.
[0073] This embodiment quickly determines multiple variable height beam structure design solutions through the second parameter value and the first parameter range, and can provide a solution that meets safety requirements and is economical in less time. It solves the problem of lack of theoretical support when designers design variable height beam structures, and can provide a preferred solution with a lighter structure while ensuring safety.
[0074] In an optional embodiment, step S3 includes:
[0075] S4. Construct a finite element model of the ship.
[0076] S5. Input parameter values of the target variable height beam structure into a finite element model, and output a stress cloud diagram of the target variable height beam structure to evaluate the safety of the target variable height beam structure.
[0077] The parameter values of the target variable height beam structure include the cross-sectional area of the target variable height beam structure, the section modulus of the target variable height beam structure, the panel width of the target variable height beam structure, the panel thickness of the target variable height beam structure and the web thickness of the target variable height beam structure.
[0078] This embodiment implements parametric modeling in a dimension-driven manner on Apex. Specifically, through the design drawing information of the ship and the preliminary design plan of the target variable height beam structure, the deck modeling range and plate thickness, the size specifications of the beams, longitudinal girders, longitudinal bones, and pillars, the size and layout area of the variable height beam panel and web are used as model input parameters to automatically complete geometric modeling, add physical properties, and finally output finite element results to output the final safety assessment plan of the target variable height beam structure.
[0079] Through the finite element model of this embodiment, not only the parameter values of the target variable height beam structure are taken into account, but also the influence of environmental parameters such as the deck, beam, longitudinal bone, pillar, layout area, etc. The output safety assessment results of the target variable height beam structure are more reliable.
[0080] It should be noted that the workflow of the variable height beam structure design method for a ship is managed and controlled through a user integrated interface, which includes a menu bar displaying a plurality of controls, each of which accesses an interface corresponding to a stage in the workflow, and each such interface is configured as:
[0081] Data about the corresponding stage in the workflow is retrieved from the computer environment.
[0082] The retrieved data is displayed in this interface.
[0083] Receive user input related to the corresponding stage in the workflow.
[0084] Based on the user input, data is transmitted to the computer environment.
[0085] A specific example is introduced below, which is applied to a cruise ship design scenario, and the variable height beam structure design method of the ship of this embodiment is explained in detail.
[0086] The variable height beam structure design method in this example requires the use of three design tools, namely the user integrated interface, the variable height beam multi-design parameter selection tool, and the variable height beam parametric modeling tool. The interaction and effects of the three design tools are shown in the figure. Figure 3As shown. It can be seen that the user can adjust the range of the variable parameters of the variable height beam design through the user integrated interface (i.e., adjust the panel thickness range of the variable height beam structure, the panel width range of the variable height beam structure, and the web thickness range of the variable height beam structure), and can also input the design parameters of the deck and variable height beam into the variable height beam parametric modeling tool through the user integrated interface to automatically build a finite element model and perform a finite element structural safety assessment. The variable height beam multi-design parameter selection tool is used to determine the preliminary design scheme of the variable height beam (i.e., the target variable height beam structure).
[0087] In the workflow of the variable height beam structure design method, the user integrated interface is responsible for displaying, receiving, inputting data and providing a graphical interface to the user. Based on Python language (a high-level programming language), the program parameter input interface is implemented through Apex native API (application programming interface) and WPF control (a user interface framework for building desktop client applications); the filter control is used to implement the selection restriction of the user in the graphical interface. In database applications, the rational use of controls is an effective way to improve development efficiency. The controls used in the development program include: command button control, text box control, check box control, ComboBox control (a commonly used graphical user interface component), and frame control. The final interface will be passed to the variable height beam design tool for processing. The user integrated interface has three basic functions: control the script process, realize the interaction with the user by adding command buttons; realize the reading of the input value of the structural parameter, prompt the function of each input box through the input box and the corresponding text, and pass it to the variable height beam design tool; create a deck beam logo so that the user can select the deck beam. Use internal controls to design each information window.
[0088] The design process of this example is as follows Figure 4 As shown:
[0089] S401. Determine the web height and specification parameter range of the variable height beam according to the deck design drawings, classification society specifications, and air duct, piping, and electrical layout drawings.
[0090] S402, such as Figure 5 As shown in the Apex platform, through the user integrated interface, use the variable height beam multi-design parameter selection tool according to the specification parameters, and select the parameter scheme given by the program (such as Figure 6 As shown in the figure, select appropriate parameters according to the actual situation and determine the preliminary design scheme of the target variable height beam structure.
[0091] S403, through the user integrated interface in the Apex platform, use the deck and pillar creation module of the variable height beam parametric modeling tool, such as Figure 7 and Figure 8As shown in Figure 1, the deck and pillar models are created according to the deck design drawings. In the Apex platform, the variable height beam creation module (such as Fig. 9 As shown in Figure 2), the variable height beam model is created according to the preliminary design of the target variable height beam structure. Fig.10 As shown. In the Apex platform, through the user integrated interface, the finite element output module (such as Fig.11 As shown in Figure 2), finite element analysis was performed. The results are shown in Figure 2 Fig.12 As shown, the safety of the target variable height beam structure is evaluated. If it meets the requirements, the final design scheme of the variable height beam is formed. If it does not meet the requirements, a new set of data is selected to repeat the above steps.
[0092] It should be noted that the functions of the variable height beam multi-design parameter selection tool are as follows Fig.13 As shown in the figure, the variable height beam multi-design parameter selection tool includes a control program and a genetic algorithm function. The control program is responsible for receiving the original constant height beam structure parameters and the variable height beam parameter variable range and passing them to the algorithm function to generate the initial population. Each variable height beam structure design corresponds to an individual in the population. The three parameters of the variable height beam structure's panel width, panel thickness, and web thickness correspond to the first gene, second gene, and third gene of the individual.
[0093] The control program also evaluates the performance of individuals in the population by defining a fitness function. The fitness function of this example is written based on the cross-sectional area, section modulus and structural weight of the variable height beam. For each individual in the population, its fitness needs to be calculated. The higher the fitness of the individual, the more likely it is to be retained in the subsequent evolution process. The control program feeds back the individual fitness to the genetic algorithm function to sort, select, recombine and mutate the genes. Repeat the fitness evaluation, selection, crossover and mutation operations to generate a new population until the termination condition is met (such as reaching the maximum number of iterations, or finding a satisfactory solution). Ultimately, it is ensured that the cross-sectional area and section modulus of the variable height beam are not less than the original equal height beam structure, and a design scheme with the minimum weight of the variable height beam structure is given.
[0094] The final program of the control program will feed back the historical optimal fitness function value (i.e., the cross-sectional area and section modulus of the variable height beam) and the corresponding input values (i.e., the panel width, thickness and web thickness of the variable height beam).
[0095] It should be noted that the variable height beam parametric modeling tool implements parametric modeling in the form of dimension-driven on Apex by calling the interface (API) of Apex. That is, according to the design drawing information and the preliminary design plan of the target variable height beam structure, the deck modeling range and plate thickness, the size specifications of the beams, longitudinal girders, longitudinal bones, pillars, the size and layout area of the variable height beam panel, web plate, etc. are input, and the geometric modeling, physical properties are added, and the finite element results are finally output to form the final target variable height beam structure safety assessment plan.
