Description

PIN JIG MODELING SYSTEM AND METHOD FOR VESSEL

The present invention relates to a pin jig modeling system and method of a ship, and more particularly to a modeling system and method for optimal pin jig design for the operation of the assembly of the ship.

Ships are special products that are built at the request of the owner or orderer and are produced by welding or assembling thousands or tens of thousands of members.

The shipbuilding industry is the largest and most comprehensive assembly industry that processes or assembles equipment from various industries such as steel, machinery, electronics and chemicals. In the same assembly industry, the automotive work process can be standardized, but the shipbuilding industry is not only large and complex, but also difficult to standardize the work process due to the different ship structures required by different owners or owners.

The ship is not able to produce the completed hull at once, but is built through the assembly process by stacking several blocks in a dock, and the assembly process of the ship is an assembly (small assembly) by assembling a plurality of members. -> Heavy Assembly-> Contrast)) and assembling the assembly to create blocks and welding the created blocks to complete the hull.

The outer shell of a ship can be divided into flat panels without curvature and curved plates with constant curvature.

In the assembly of assemblies with flat panels with no curvature, assembly is possible on a general assembly table (large workbench), but with a curvature panel or side shell plate having a constant curvature. Flat plate plates cannot be used in assembly.

Therefore, a plate-shaped plate that fits the curvature of the curved plate or side shell plate is required, which is called a pin jig.

In order to support blocks weighing from tens of kilograms to hundreds of tons, the choice of materials for casting the pin jigs itself is important, but they are precisely designed and manufactured to have the optimal pin jig arrangement and height to accurately support the outer plate of the block. It is also very important.

Pin jig for the operation of the assembly needs to be designed so that the height from the ground is minimal. The higher the height of the pin jig, the greater the number of unreasonable manufacturing conditions, such as safety issues and unreasonable welding conditions due to the height of the operation of the block or assembly.

What is important for the optimal pin jig placement and height setting is where the reference plane of the jig is. If the height of the jig is set by incorrectly setting the reference plane, the average height of the jig is inevitably increased even if the jig is used to support the same block.

Conventionally, it is not possible to provide an optimal working state for assembling a block by referring to four vertex points of a curved sheet or four points of a predetermined area in the middle of a curved sheet when determining a base plane of a jig.

The ship order process includes the process of estimating 110 and contract 111 of FIG. 1, including the requirements of the ship owner (type, size, route, ship, delivery date, etc.), construction specifications, shipbuilding capacity and order. Reviewing the basic matters such as the remaining amount, consulting and estimating documents are submitted to the owner (110), and the owner selects the shipyard with the proper conditions and contracts (111). In some cases, the ship owner decides on the shipyard.

The design process of the ship includes the basic design 120, detailed design 121 and production design 122 process. The design process is carried out sequentially and divided into hull design and design design. The design process may further include an initial design and conceptual design process, and the initial design and conceptual design process located at the preliminary stage of the basic design 120 may include the requirements (ship type, load capacity, size, It is the process of deriving the concept of optimal ship that satisfies ship speed, hull structural strength, etc.). It is a design that proves the concept design and the performance of all the developed ships through the ship's records, calculations, and experiments built in the past, and confirms the basic performance and equipment specifications of the ship.

The basic design process 120 is generally a drawing for estimating design and construction. Based on the main performance of the ship determined in the initial design in the stage before detailed design 121, concrete structure of the hull, main engine of engine room, arrangement of various equipment, piping system diagram, electrical arrangement, deck equipment arrangement, navigation It is the process of defining equipment, residential facilities, etc. in detail. Various drawings, bills, specifications, etc. derived from this process are to be approved by the owner, and safety-related drawings are to be approved by the Society.

The detailed design (121) process is to create the actual construction drawings required for ship construction. The detailed design results are expressed in detail for each sub-part, and the overall performance calculation and detailed design of the hull structure are performed mainly for ship calculation. It is a process. The exact quantity of raw materials required for production and ordering of equipment are derived, and material ordering is provided and data for production planning are supplied.

The production design 122 process is a step of designing a la carte drawing and a detail drawing for the processing of the member based on the result of the detailed design 121. Process that accurately derives production information (NC machining information, work order, method, work drawing showing the connection and dimensions of members, attachment detail of various mechanical equipment, etc.) necessary for operator or machine operation with emphasis on workability and economic efficiency to be.

The hull construction works are stored in the steel loading dock for each product produced when the steel materials ordered by the shipyards (steels that have been inspected by the ship class) are received from the steel mill. Steel construction pre-treatment (grinding to remove rust and painting to prevent rust) is carried to the processing plant by construction order.

Machining 140 process is made in the processing plant, such as marking, cutting, bending (molding).

The assembly work includes granulation and non-assembly processes, in which the members are assembled and welded to each other in the small assembly site to form blocks. When the block is completed, it is mounted as a large block that can be mounted on the crane, completes the watertight welding, and launches it into the fleet or dock.

The pin jig modeling system and method of the ship in the present invention belongs to part of the production design 122 process in FIG.

2 is a view showing an embodiment of the pin jig plate.

Plain flat assemblies without curvature can be assembled on a regular assembly plate, but flat plates or side assemblies with curvature cannot use flat plate plates. Therefore, a pin-shaped pin jig plate for each curvature is required.

The shipyard generates a pin jig for each side assembly for each side assembly and provides a drawing. In the factory, a pin is set through the pin jig drawing and an assembly or a block is assembled.

Pin jigs designed or manufactured by the system and method according to the present invention, as an embodiment, the load received per pin jig can be set from several tens of kilograms to several tons, and may be manufactured to adjust the pin jig height for convenience.

The weight of the block to be worked on the pin jig plate may be about 200 to 250 tons in one embodiment, and the size of the block to be assembled may be about 20 × 22 m.

The pin jig spacing on the surface plate can be set at intervals of 1 m or 2 m, respectively, in the width direction and the length direction. The material for the pin jig casting may be different according to each part, and as an example, may be cast using carbon steel, rolled steel, and carbon steel pipe for pressure piping.

3 is a view showing a flowchart of a pin jig modeling method of a ship according to the present invention.

The pin jig modeling method of the ship according to the present invention begins by driving the pin jig modeling program of the ship (S310).

After the driving of the program, the step of determining the reference surface of the pin jig plate is performed, but before this, the process of converting a curved panel into a three-dimensional solid model may be included.

4 is a view showing an embodiment of a curved surface modeled in a three-dimensional shape in the pin jig modeling system and method of the ship according to the present invention.

Strictly speaking, the shape of the curvature does not exist in the modeling program, but is actually a combination of seam and butt lines, which are boundary welds.

In seam and seam welding line, seam line means the welding line in the horizontal direction, butt line means the welding line in the width direction of the ship, that is, the transverse direction.

In the present invention, however, the seam line and the butt line are not specifically distinguished, and the seam line and the butt line are not strictly distinguished as the line indicating the positional information of the boundary line (boundary line) for defining the curved plate.

Split into eight constant width strips between seam and seam lines or between butt and butt lines for conversion to a three-dimensional solid model. In the present invention, the eight strip dividing is only one embodiment, and is not necessarily limited to eight strips.

In the case of dividing into eight strips, strip lines are generated at the end of each strip, resulting in nine strip lines.

In the present invention, the points on each strip line are converted into B-spline curves by using the node point position information of the strip lines used when the shell is developed for 3D modeling. Find the passing surface.

FIG. 4 (a) shows a process of obtaining a B-spline curve from points on a strip line, and FIG. 4 (b) shows the results of repeating the process of FIG. 4 (a) for each strip. FIG. 4 (c) shows all strips. Shows the result of obtaining the final 3D modeling surface by performing the B-spline curve for.

One of the features of the pin jig modeling method according to the present invention lies in the reference plane setting of the surface plate.

The platen of the pin jig has a constant width and length to carry out the assembly work of the curved sheet or the flat plate.

As mentioned above, the lower the average height of the pin jig, the more optimal it is.

The sum of the squares of the linear distances from the plurality of node points on the outer plate of the ship assembly is minimized, and the base plane of the surface plate including the plurality of pin jigs is calculated with a constant width and length. (S320).

The process of setting the base plane of the pin jig surface is specifically divided into a plurality of strips having a constant width between two arbitrary seam lines on the shell of the ship assembly, and divided into strips. Recognize the position of a plurality of node points on the strip line at the end, and find the sum of the squares of the linear distances from the node points to a predetermined plane, but the sum of the squares of the linear distances is the minimum Set as the base plane.

FIG. 5 is a diagram for conceptually explaining a least-square method in setting a reference plane of a pin jig plate in the pin jig modeling system and method according to the present invention.

Least-squares means that the measured value is measured over N times (e.g., node points on the stripline), y1, y2, ..., yn is some other measured value (e.g., the reference plane of the surface) x1, x2, ... can be estimated as a function of xn,

Sum of squared difference between measured value yi and function value f (xi)

The principle of least squares is to find a function f (x) that is equal to the minimum.

The function y = f (x) thus obtained is the best function for the relationship between these measurements.

Each point indicated in FIG. 5 is a measured value (xi, yi), and a straight line (xi, f (xi)) is a linear function that best represents a distribution of measured values, obtained using the least squares method.

In other words, this function is a straight line in which the sum of (measurement-function values) ² (sum of errors) is minimized. In FIG. 5, the measurement is limited to values on the y-axis in order to explain the concept of the least square method, but in the present invention, the points on the strip line actually have two-dimensional information.

Arbitrary points on the strip line in the pin jig modeling system and method of a ship according to the invention have two-dimensional positional information.

Therefore, the plane where the sum of the squares of the linear distances from the points on the strip line to any plane becomes the minimum becomes the reference plane of the pinzig plate. That is, the straight line in FIG. 5 represents a plane.

A two-dimensional position of the pin jig arranged on the reference surface of the surface plate is set (S330).

The pin jig position setting receives the position of the pin jig as a reference among the plurality of pin jigs and the arrangement interval of the pin jig in the width direction (X axis) on the reference plane and the arrangement interval of the pin jig in the longitudinal direction (Y direction). By doing so.

The linear distance from the two-dimensional position of the pin jig on the reference plane to the outer plate of the ship assembly is calculated and set to the height of the pin jig (S340).

On the basis of the two-dimensional position of the pin jig and the height of the pin jig, the pin jig on the reference plane is provided by the three-dimensional schematic (S350).

The reference surface of the pin jig surface is specified by a frame angle, a water line angle, and a transverse angle.

One of the features of the system and method of the present invention is that the pin jig can be easily redesigned by adjusting the angle of the reference plane of the pin jig.

6 is a view showing an angle for specifying a reference plane of the pin jig surface according to the present invention.

The transverse angle is the optimal jig base angle on the frame section (X cross section) (FIG. 12A).

Frame angle is the self-weight angle (mounting angle) with respect to the jig base of the frame (X surface) made in the orthogonal cross section of the reference surface (base surface) which consists of lateral angle values (FIG. 12B).

The plan angle is the jig base angle on the waterline view determined while performing the optimal jig placement operation (FIG. 12C).

The water line angle is the self-weighting angle (mounting angle) with respect to the jig base of the plane (z-plane) made in the right-angled cross section of the reference plane formed of the plane angle value (Fig. 12D).

The angle for mounting the girder (y) may be mounted at right angles to the frame angle and the waterline angle.

7 is a view showing the concept of the outer plate in the pin jig design system and method for setting the height of the pin jig excluding thickness.

One of the features of the pin jig design system and method according to the present invention is the three-dimensional solid modeling of the shell mentioned above to solve the problem of setting the height of the pin jig without excluding the width of the conventional shell. The height of the pin jig can be calculated or designed by excluding the thickness T of the shell in the process.
