Description

Technical Field

[0001] This invention relates to ship cabin design technology, and more particularly to a rule-driven rapid design method for ship cabin insulation. Background Technology

[0002] The complexity of ship cabin insulation, including its functional requirements, installation scope, and structural intricacy, makes 3D insulation modeling challenging and difficult to integrate into the overall balancing of 3D ship design. Traditional insulation statistics methods, based on insulation layout diagrams and 2D structural drawings, calculate the insulation material for each cabin's ceiling, forewall, aftwall, portwall, and starboardwall. This approach has limitations. It requires manual classification, measurement, and calculation, resulting in low efficiency and susceptibility to errors, omissions, and miscalculations. This not only prolongs the insulation quantity calculation process but also leads to significant discrepancies between the calculated results and actual quantities, potentially causing material shortages or waste and increasing shipbuilding costs.

[0003] With the increasing demand for refined ship design, three-dimensional digital design has gradually become the most effective technical means to achieve lean ship design. Therefore, how to quickly realize three-dimensional design of cabin insulation and obtain accurate insulation material statistics is an urgent problem to be solved. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a rule-driven rapid design method for ship compartment insulation, which addresses the deficiencies in the prior art.

[0005] The technical solution adopted by this invention to solve its technical problem is: a rule-driven rapid design method for ship compartment insulation, comprising the following steps:

[0006] 1) Create a parameterized insulation section template;

[0007] The insulating section templates include bulb flat steel insulating templates, T-shaped steel insulating templates, flat steel insulating templates, and sheet metal insulating templates;

[0008] in,

[0009] 1.1) The parameters of the bulb flat steel insulation template include: the specifications of the bulb flat steel insulation section and the laying length of the bulb flat steel insulation. The specifications of the bulb flat steel insulation section are related to the width of the bulb flat steel, the thickness of the web, the height of the bulb head, the radius of the rounded corner between the top surface of the bulb and the web, and the radius of the rounded corner at the end of the bulb.

[0010] 1.2) The parameters of T-shaped insulating templates include: T-shaped insulating cross-sectional specifications and T-shaped insulating laying length. The T-shaped insulating cross-sectional specifications are related to the height, web thickness, panel width and thickness of the T-shaped template.

[0011] 1.3) The parameters of the flat steel insulation template include: the specifications of the flat steel insulation cross section and the laying length of the flat steel insulation. The specifications of the flat steel insulation cross section are related to the thickness and width of the flat steel.

[0012] 1.4) The parameters of the sheet insulation template include: sheet insulation cross-sectional specifications and sheet insulation laying length. The sheet insulation cross-sectional specifications are related to the insulation thickness, the distance between adjacent bulb flat steel insulation, the distance between bulb flat steel insulation and T-shaped insulation, and the distance between bulb flat steel insulation and sidewall.

[0013] 2) Using design software, embed knowledge engineering rules for different insulation templates; these rules run automatically upon initial installation and upon modification, including:

[0014] By reading relevant parameters of structural plates and profiles in real time, the insulation cross sections of the plates and profiles are calculated and named according to design rules.

[0015] Calculate the laying area of ​​the sheet insulation and the laying length of the profile insulation, obtain the density through the insulation material properties, get the insulation weight and assign it to the model properties;

[0016] Obtain information on the location, dimensions, material, thickness, laying area, length, and weight of the insulation for quantity statistics.

[0017] 3) During insulation installation, select the corresponding insulation section template according to the structure of the ship's cabin in the current scenario, extract the cross-sectional specifications and length parameters of the profiles of the ship's cabin as well as the laying area parameters of the plates to complete the laying of plate insulation and profile insulation.

[0018] 3.1) Select the corresponding insulation section template according to the structure of the ship cabin in the current scenario. The insulation section template in the newly created insulation model is connected with the structural model of the ship cabin. Match the cross-sectional specification parameters of the laying object, and limit a certain laying length through parameter driving to generate the corresponding insulation.

[0019] 3.2) Knowledge engineering rules are implemented during the initial insulation installation to achieve insulation location information matching, automatic naming, and weight calculation;

[0020] 4) Rule-driven modifications to cabin insulation design;

[0021] When the structural position and specifications of a ship's compartments are adjusted, the knowledge engineering rules automatically run after the parameters are modified, reassess the existing insulation status, and make corresponding adjustments to the insulation of connected plates and profiles.

[0022] The beneficial effects of this invention are:

[0023] The rule-driven rapid design method for compartment insulation provided by this invention embeds design rules such as insulation modeling, naming, and material statistics into a parametric insulation template. Designers can automatically and quickly generate a 3D model of the compartment insulation after selecting the laying object, enabling rapid compilation of the insulation material list and avoiding a large amount of repetitive manual operations in the traditional insulation design process. This method significantly improves the efficiency of insulation modeling and the accuracy of material statistics, greatly shortening the design cycle. Attached Figure Description

[0029] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0030] like Figure 1 As shown, a rule-driven rapid design method for ship compartment insulation includes the following steps:

[0031] Step 1) Create a parameterized insulation section template;

[0032] The insulating section templates include bulb flat steel insulating templates, T-shaped steel insulating templates, flat steel insulating templates, and sheet metal insulating templates;

[0033] in,

[0034] 1.1) The parameters of the bulb flat steel insulation template include: the specifications of the bulb flat steel insulation section and the laying length of the bulb flat steel insulation. The specifications of the bulb flat steel insulation section are related to the width of the bulb flat steel, the thickness of the web, the height of the bulb head, the radius of the rounded corner between the top surface of the bulb and the web, and the radius of the rounded corner at the end of the bulb.

[0035] 1.2) The parameters of T-shaped insulating templates include: T-shaped insulating cross-sectional specifications and T-shaped insulating laying length. The T-shaped insulating cross-sectional specifications are related to the height, web thickness, panel width and thickness of the T-shaped template.

[0036] 1.3) The parameters of the flat steel insulation template include: the specifications of the flat steel insulation cross section and the laying length of the flat steel insulation. The specifications of the flat steel insulation cross section are related to the thickness and width of the flat steel.

[0037] 1.4) The parameters of the sheet insulation template include: sheet insulation cross-sectional specifications and sheet insulation laying length. The sheet insulation cross-sectional specifications are related to the insulation thickness, the distance between adjacent bulb flat steel insulation, the distance between bulb flat steel insulation and T-shaped insulation, and the distance between bulb flat steel insulation and sidewall.

[0038] 2) Using design software, embed knowledge engineering rules for different insulation templates; these rules run automatically during the initial insulation creation and installation, and when modifications occur, including:

[0039] By reading relevant parameters of structural plates and profiles in real time, the insulation cross sections of the plates and profiles are calculated and named according to design rules.

[0040] Calculate the laying area of ​​the sheet insulation and the laying length of the profile insulation, obtain the density through the insulation material properties, get the insulation weight and assign it to the model properties;

[0041] Obtain information on the location, dimensions, material, thickness, laying area, length, and weight of the insulation for quantity statistics.

[0042] 3) During insulation installation, select the corresponding insulation section template according to the structure of the ship's cabin in the current scenario, extract the cross-sectional specifications and length parameters of the profiles of the ship's cabin as well as the laying area parameters of the plates to complete the laying of plate insulation and profile insulation; the profiles include bulb flat steel, T-shaped steel and flat steel;

[0043] 3.1) Select the corresponding insulation section template according to the structure of the ship cabin in the current scenario. The insulation section template in the newly created insulation model is connected with the structural model of the ship cabin. Match the cross-sectional specification parameters of the laying object, and limit a certain laying length through parameter driving to generate the corresponding insulation.

[0044] 3.2) Knowledge engineering rules are implemented during the initial insulation installation to achieve insulation location information matching, automatic naming, and weight calculation;

[0045] 4) Rule-driven modifications to cabin insulation design;

[0046] When the structural position and specifications of a ship's compartments are adjusted, the knowledge engineering rules automatically run after the parameters are modified, reassess the existing insulation status, and make corresponding adjustments to the insulation of connected plates and profiles.

[0047] The following examples on the 3DExperience platform are only used to more clearly illustrate the technical solution of the present invention. Taking bulb flat steel insulation as an example, a specific implementation description is provided:

[0048] 1) Create the three-insulation section of the spherical flat steel;

[0049] Create two cross-sectional profiles, inner and outer, using a sketch to complete the creation of the spherical flat steel insulation cross-section.

[0050] Set the control parameters for the insulating section of the bulb flat steel, including the width b, height h, web thickness s, and total height H of the bulb head, such as... Figure 2 As shown.

[0051] Set the external parameter laying length L. The length L parameter is used to control the laying length of the bulb flat steel insulation. Set a default value for it, which is generally consistent with the length of the bulb flat steel. In practice, it can be defined according to the limit boundary or value.

[0052] To facilitate the use of rule-driven cabin insulation section templates, an insulation section template library can be established.

[0053] 2) Embedding knowledge engineering rules;

[0054] The naming convention for bulb flat steel insulation is "TQ specification". Here, TQ represents "bulb flat steel insulation"; the specification is defined based on the specifications of the bulb flat steel, such as "HP60x5" bulb flat steel, whose insulation specification is "TQ6". Following this rule, different specifications of bulb flat steel insulation are named accordingly.

[0055] In the 3DExperience platform, you can use "Rule" to write knowledge engineering rules into a template, and the rules will run automatically when the parameters are updated.

[0056] 3) Rule-driven cabin insulation installation process, see details below. Figure 3 ;

[0057] Bulb flat steel insulation is typically laid on bulb flat steel plates in decks, bulkheads, or outer plates. Designers use an insulation section template library to access bulb flat steel insulation templates. Given a specific object, the software automatically reads the object's height, thickness, width, and radius, writes these specifications into its own attributes, and uses the H, b, s, and h parameters to achieve adaptive control of the bulb flat steel insulation section specifications. The laying length L is generally the same as the bulb flat steel length by default, but designers can adjust the laying length according to constraints.

[0058] At this point, the parameters change, activating the embedded knowledge engineering rules. Based on the current bulb flat steel insulation, the H, b, s, and h parameters are read to form the specifications of the bulb flat steel insulation, completing the automatic naming of the bulb flat steel insulation. The volume and density of the bulb flat steel insulation are obtained, and the weight of the bulb flat steel insulation is calculated.

[0059] Based on the complete cabin insulation model and its properties, the precise amount of cabin insulation required is obtained through weight calculation and according to the laying location. For detailed statistics on insulation usage, please refer to [link to relevant documentation]. Figure 4 .

[0060] 4) Rule-driven adaptive modification of cabin insulation;

[0061] After selecting bulb flat steel as the object for laying, the insulation cross section of the bulb flat steel is adaptively adjusted according to the control parameters, and the laying length L can be modified by reassigning values, thereby modifying the insulation of the bulb flat steel.

[0062] When the cross-sectional dimensions or location of the bulb flat steel are modified, the nodes of the bulb flat steel insulation in the cabin are directly updated in the 3DExperience platform. The rules will re-identify the updated location information and related parameters of the bulb flat steel, and adaptively adjust the corresponding bulb flat steel insulation dimensions or location information using control parameters, which will be reflected in the geometry of the bulb flat steel insulation.

[0063] At this point, the parameters are modified, activating the embedded knowledge engineering rules. The system reads the H, b, s, and h parameters to determine the specifications of the bulb flat steel insulation and automatically names it. The volume of the bulb flat steel insulation is then retrieved, and combined with its density, the weight is calculated.

[0064] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
