[0040] The following specific embodiments illustrate the embodiments of the present invention, and those familiar with the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present application. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0041] It should be noted that the diagrams provided in the embodiments of the present invention are only used to illustrate the basic concept of the present invention in a schematic manner. Although the diagrams only show the components related to the present invention rather than being drawn according to the number, shape and size of the components in actual implementation, the form, quantity and proportion of each component can be changed at will during actual implementation, and the layout of the components may also be more complex. The structures, proportions, sizes, etc. illustrated in the drawings of the specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the limiting conditions that can be implemented in this application, so they have no technical substantive significance. Any structural modification, change in proportional relationship or adjustment of size should still fall within the scope of the technical content disclosed in this application without affecting the effects and purposes that can be achieved by the present invention.

[0042] In view of the problems existing in the background technology, the present invention provides a method for calculating the single-sided area of ​​outfitting parts, and the single-sided area calculation method includes defining a part modeling method: including defining materials, part specifications, part node types, etc. Part specifications of different materials are obtained according to the modeling method. The single-sided area of ​​the part is counted according to the part specifications, and the area value is summarized and output. In the field of ship design and construction, the parts of equipment and outfitting involved in different areas are of different materials. For example, the liquid tank area of ​​a liquefied gas carrier is used to store and process extremely low-temperature gases, resulting in the material of the outfitting parts in this area being low-temperature steel material to meet the application conditions under low-temperature conditions. The railings, ladders, bases, platforms and other outfitting parts in this area need to count the area of ​​the profiles or plates of their parts, and order low-temperature steel plates from supply chain manufacturers based on the statistical area. The automatic single-sided area statistics method based on part material proposed in the present invention can improve the efficiency of ship production design and realize the concept of a single data source based on a model.

[0043] The present invention is described in detail below with reference to specific embodiments.

[0044] This embodiment provides a method for calculating the single-side area of ​​an outfitting part, and the single-side area calculation method includes:

[0045] S1: Define the modeling method of outfitting parts, including defining the node type, material and specification of outfitting parts;

[0046] Specifically, outfitting parts include railings, ladders, bases, platforms, etc. Each outfitting part is composed of various outfitting parts. For example, the railing is composed of parts such as railing columns, railing handrails, and doubler plates. The ladder is composed of parts such as ladder frames, steps, ear plates, and doubler plates. The base is composed of angle steel, doubler plates, panels, etc. There are two types of node types for outfitting parts: the first outfitting part node type (Product type) and the second outfitting part node type (Part type). These two node types correspond to these two modeling methods respectively. The Product type is generally used for outfitting parts such as bases and platforms, and the Part type is generally used for railings, ladders, etc.

[0047] The first outfitting part node type (Product type) includes outfitting part nodes such as base and platform. In the first outfitting part node type, the outfitting part node includes at least one outfitting part node, and the specifications, materials and shapes of each outfitting part are located under the part node corresponding to the outfitting part. For example, Figure 2 The outfitting parts nodes included in the base outfitting nodes include panel nodes, bracket nodes, support plate nodes, angle steel nodes, flat steel nodes and triangular composite plate nodes. Figure 4 The bracket node shows the bracket specifications, materials, shapes and other parameter information. Figure 5The parameter information about the angle steel, such as specifications, materials and shapes, under the angle steel node is displayed.

[0048] The second outfitting part node type (Part type) includes the outfitting part nodes such as railings and ladders. In the second outfitting part node type, the outfitting part node includes the outfitting part part name and parameter information related to the outfitting part part, and the outfitting part part and the parameter information related to the outfitting part part are listed under the outfitting part node. That is, Figure 2 As shown in the figure, all parts under this node type are listed under the same node, and the materials and specifications of all parts are also stored under this node in the form of parameter sets. Among them, the parameter information includes the single-side area of ​​the outfitting parts.

[0049] S2: Obtain the material of the outfitting parts to be counted, and obtain the outfitting parts to be counted based on the material of the parts;

[0050] The material of the outfitting parts to be counted is obtained, for example, the parts of the outfitting parts with Q235B material are counted, and the parts with non-Q235B material are not counted. Based on the material and specification information of the outfitting parts defined in step S1, all the outfitting parts of the part material can be obtained.

[0051] S3: determining the node type of the outfitting part corresponding to the outfitting part, and obtaining the specification of the outfitting part based on the node type of the outfitting part;

[0052] After obtaining all the outfitting parts that need to be counted, first determine the node type of the outfitting part based on the outfitting part. Obtain the part specifications of the outfitting part based on the node type. For the outfitting part whose node type is the first outfitting part node type (Product type), the specifications of the outfitting part can be obtained under the part node corresponding to the outfitting part. For example, Figure 4 As shown in the figure, Product type outfitting such as base, its parts such as bracket are made of Q235B material and 10mm thickness, all under this bracket part node. Figure 5 As shown in the figure, the material of the angle steel is Q235B and the specification is L75×75×10, which are all under this angle steel part node. For the outfitting parts whose node type is the second outfitting part node type (Part type), the specifications of the outfitting parts are obtained in the parameter information under the outfitting part node. For example, Figure 6 As shown in the figure, for Part type outfitting parts such as straight ladders, the materials and specifications of its parts such as ladder frames, ear plates, and steps are stored in parameter form. The material of the step is Q235B, and the specification is square steel 22×22, all of which are under the parameter set information node.

[0053] S4: Count the single-side area of ​​each outfitting part based on the specifications of the outfitting parts to be counted;

[0054] Counting the single-side area of ​​each outfitting part based on the specifications of the outfitting part to be counted includes judging the type of the outfitting part based on the specifications of the outfitting part, and calculating the single-side area of ​​the outfitting part based on the type of the outfitting part.

[0055] Specifically, for the outfitting parts whose outfitting parts node type is the first outfitting parts node type (Product type), the part type is determined based on the specifications of the part (Q235B material) under the Product type node obtained in step S3, for example, the part is determined to be a plate or a profile. For example, based on the plate thickness part specification of 10 mm, the part is determined to be a plate. Figure 7 As shown in the figure, if the part is a plate, the program obtains the surface in the non-plate thickness direction, takes one of the calculated areas, and then the single-side area can be obtained. If the part is a profile, for example, the specification is angle steel L75×75×10, the judgment rule is that the specification that is not the plate thickness is determined to be a profile. Figure 8 As shown in the figure, if the part is a profile, the width of the profile after unfolding is calculated according to the profile specifications. For example, after the angle steel L75×75×10 is unfolded, its width is 140mm (75mm+75mm-10mm=140mm). The program obtains the length value of the angle steel. Fig. 9 The figure shows the length of the angle steel reference line in the part node. The single-side area value of the profile is equal to the length value multiplied by the width value. Other profiles can refer to this method to calculate the length value and width value (just expand them), and multiply the two to get the single-side area value. Finally, calculate the sum of the single-side areas of the Product type outfitting node (the sum of the single-side areas of the parts).

[0056] For an outfitting part whose node type is the second outfitting part node type (Part type), the specification of the outfitting part is obtained based on the parameter information under the outfitting part node, and the single-side area in the parameter information can be directly obtained. Fig.10 , directly obtain the single-side area parameter of the part (Q235B material) under the Part type node. After the single-side area parameter is completed according to the model layout, this parameter can be automatically generated.

[0057] The automatic generation rules of the single-sided area parameter are as follows:

[0058] By obtaining the part specification as a thickness value, it can be determined to be a plate. The calculation method of its single-side area value is the same as that of the Product type outfitting parts, and the single-side area value is written into the single-side area parameter. By obtaining the part specification as a non-thickness value, it can be determined to be a profile. Its single-side area value is obtained by calculating the length and width of the profile after unfolding and multiplying them. Its length value is obtained by the given parameter value in the node, such as Fig.11The ladder length value shown in . The width value is calculated in the same way as the Product type outfitting parts, and the single-side area value is written into the single-side area parameter. Finally, the sum of the single-side areas of the Part type outfitting parts nodes (the sum of the single-side areas of the parts) is calculated.

[0059] S5: Based on the single-side area of ​​each outfitting part, calculate the total single-side area of ​​the outfitting parts that need to be counted.

[0060] After step S4, based on the single-side area of ​​each outfitting part, the total single-side area of ​​the outfitting parts to be counted is calculated.

[0061] In summary, the method for calculating the single-sided area of ​​outfitting parts of the present invention includes defining a modeling method of outfitting parts, and defining a modeling method of outfitting parts includes defining node types of outfitting parts, and part materials and specifications of outfitting parts. Obtain the material of the outfitting parts that need to be counted, and obtain the outfitting parts that need to be counted based on the part material. Determine the node type of the outfitting parts corresponding to the outfitting parts, and obtain the specifications of the outfitting parts based on the node type of the outfitting parts. Count the single-sided area of ​​each outfitting part based on the specifications of the outfitting parts that need to be counted. Based on the single-sided area of ​​each outfitting part, calculate the total value of the single-sided area of ​​the outfitting parts that need to be counted. Therefore, the method for calculating the single-sided area based on part material of the present invention can improve the efficiency of ship production design and realize the concept of a single data source based on a model.
