Description

[0001] The present invention relates to a hull modeling method for hull piping,

The present invention relates to a method of modeling a hole for hull piping, and more particularly, to a method of modeling a hole for hull piping that automatically determines the type and size of a hole through automatic recognition of a modeled piping structure.

Hole modeling is one of the important tasks in the ship design and hull design. Hole modeling in shipbuilding CAD systems, Tribon and AM Outfitting, is generally modeled using pipeline structures that collide (interfere) on a plate of Hull. In the hole modeling method, after confirming the pipe structure modeled by the user, the position to be installed on the plate of the hull is visually confirmed, and then the hole type selection, the automatic hole size determination, and the hole modeling are completed.

Various hole types are determined according to these pipe structures, and design know-how for recognizing the type suitable for each structure and giving suitable hole type is required, and the waste of the design time required for this process also takes a considerable proportion . Since the hole size is automatically determined according to the specification based on the hole type, the hole type is a main design element.

Prior art patents which can be referred to in this connection include Korean Patent Laid-Open Publication No. 2011-0091123 and Korean Patent Laid-Open Publication No. 2008-0097524.

The former patent includes a step of performing modeling by selecting design information of a control pipe; Selecting design information of a supporter for fixing the modeled control pipe from the server to the hull, respectively, and performing modeling; And selecting the design information of the hull hole passing through the modeled control pipe from the server and performing modeling. Accordingly, it is possible to quickly and flexibly modify the design information, and the effect of greatly reducing the number of work performed on the site is expected.

The latter prior patent discloses a library building step of setting a standard tray; Selecting a standard tray in the library; Setting a basic attribute value for the selected standard tray; A correcting step of correcting the detailed attribute value of the tray generated according to the attribute value; A modeling step in which the tray is linked / expressed with respect to the ship coordinates on which the tray is installed and is 3D-modeled. Accordingly, it is expected that various types of cable trays can be easily modeled according to the modified length and attribute values.

However, according to the above-mentioned prior art, since the work for determining the hole type and the size corresponding to the type of the pipe structure and the design condition is distant from the workability, productivity improvement of the entire piping work is insufficient.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The present invention proposes a method of modeling a hole for mounting a piping structure on a plate of a hull. Conventional hole modeling simply relies on the method of determining the size by reading OD (Outside Diameter) data of a pipe structure such as a tube or a fitting for a hole type. On the other hand, the present invention proposes a system for automatically recognizing a hull plate and a piping structure at a position where a hole is to be installed, so that a user can easily model a desired hole without knowing the hole type and size at all.

The first step (S10) of the present invention starts with the process of recognizing the pipe structure in the construction area. The piping structure includes a tube, a coaming, a scupper, a sleeve, a flange, a coupling, and the like. Recognition of the piping structure is performed by a program that carries out the set logic, and can be linked with the shipbuilding CAD system Tribon, AM Outfitting, and the like.

The second step S20 of the present invention proceeds to a process of recognizing the plate of the construction area. The plate in the construction area means an object closely related to each of the piping structures described above. That is, the piping structure is arranged in a path determined in consideration of the plates arranged in various forms. The recognition process of the plate is performed in a separate program as in the recognition of the piping structure.

At this time, the first step (S10) and the second step (S20) are divided into the penetration, contact, and adjacency of the pipe structure to the plate. In the case where the pipe structure penetrates through the plate, the hole type formed on the plate is set differently depending on the case where the pipe structure is in contact with the plate. In case of 'Clash', the size of the hole is set to be larger than the outer shape of the pipe structure. In case of 'Touch' or 'Non', a pipe member such as a reducer should be added in addition to the hole. Here, 'adjacent' is set to a condition excluding 'pass' or 'contact'.

The third step S30 of the present invention proceeds to a process of confirming an option input from the outside. Since the program of the present invention is configured to perform the most standard and general logic, it is preferable to process non-standard and variant logic depending on the situation of the field through options.

In this case, the option of the third step S30 includes the piping conditions set by the user. The relative condition of the piping structure and the plate can be determined at an irregularity when the equipment is added or changed after the completion of the design or installation of the construction area. Therefore, the options set by the user, the designer, should be reflected first in the hole modeling process.

In the fourth step S40 of the present invention, the process of determining the type and size of the hole is completed using the recognized and confirmed information. Based on the recognition information of the first step (S10) and the second step (S20), hall modeling is presented in a set manner reflecting the confirmation information of the third step (S30). Finally, the shape and dimensions of the holes formed in the plate by the pipe structure in the construction area are displayed.

At this time, the fourth step S40 is determined by referring to the table of the hole standard stored corresponding to the pipe structure, the plate, and the option. Referring to the table of FIG. 2, a hole standard according to a piping structure, a plate, and an option is shown. NC, SN, T, S-2, ST, CF, A, SF, DP, PG, etc. described in the hole type on the right side of the table of FIG. 2 correspond to hole modeling in FIG. Actually, the standard for hole modeling is classified and stored in 200 to 300 kinds of standardized patterns in addition to those shown in FIG. 2 and FIG.

The first line of the table of FIG. 2 will be described. In the fourth step S40, if the pipe structure is a tube and the plate is 'Clash' and there is no option, do. "NC" means a state in which there is only a hole in the plate as indicated by reference numeral 7 in Fig. As shown in FIG. 2, the options can be set variously according to the definition of the user.

As described above, the present invention eliminates the manual operation from pipeline structure recognition to hole type selection, which is an essential element of conventional hole modeling, through a predetermined program in the modeling process.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit and scope of the invention as defined by the appended claims. It is therefore intended that such variations and modifications fall within the scope of the appended claims.
