Recently, as the demand for ship manufacturing has rapidly increased, various technologies that can support the shaping of the curved shell of the hull have been widely developed/distributed.

For example, Republic of Korea Patent No. 10-1650590 (Name: Method for predicting the unfolding shape of a curved abacus) (announced on August 24, 2016), Republic of Korea Patent No. 10-1570296 (Name: Heating device for forming a curved plate) ( Announced on November 19, 2015), Korean Patent Application Laid-Open No. 10-2008-105522 (Name: Hull shell plate curved surface processing system and method) (published on December 4, 2008), Republic of Korea Patent Publication No. 10-2008-100902 ( Title: Triangular heating heating pattern and path generating system and method) (published on Nov. 21, 2008), Republic of Korea Patent Publication No. 10-2012-56567 (Title: Triangular heating heating shape and positioning system and method) (2012.06) .04. Published), etc. discloses in more detail an example of conventional hull curved shell plating-related technologies.

On the other hand, under this conventional system, the curved shell plate of a ship is a three-dimensional curved surface designed based on engineering technologies such as fluid mechanics, structural mechanics, and vibration, and is manufactured by processing an iron plate of a certain thickness. It can be said that it influences the overall design performance.

At this time, the processing of the outer plate into a three-dimensional shape largely uses a two-step method. In the two-step method, mechanical primary cold working through a press or a roller, etc. and heat with a gas torch to the steel plate are used. It is divided into secondary hot working, which is applied and processed.

Cold working is a method of making a song by using a roll press, a multi press, or a bending press, and is currently mainly used in most shipyards to make a developable shape. Such a developable shape means a shape that can be made only by simple bending deformation without in-plane contraction or expansion of the cut plate.

Hot working is a process of making a steel plate into a three-dimensional curved shape by applying heat to the steel plate (steel plate) using a heat source such as a gas torch and a high-frequency induction heating device to cause contraction, expansion, and bending deformation.

On the other hand, as shown in Figure 1, the processing operation of the hull curved shell plate according to the prior art is 'the procedure for measuring the initial shape of the member (S1)', 'the procedure for matching the curved surface (S2)', 'back heating Procedure (S3) of forming an external curve (a three-dimensional shape with a mixture of convex and concave shapes in the longitudinal direction of the member) using a line (S3), 'Procedure of turning over the member (S4)', 'Linear heating wire/triangular heating wire Using , the procedure (S5) of forming a horizontal curve/vertical curve is performed, and the like.

At this time, in order to proceed with the 'procedure (S3) of forming the outer longitudinal curve (a three-dimensional shape in which the convex and concave shapes are mixed in the longitudinal direction of the member) using the rear heating wire (S3)', the operator After arranging the template having the desired shape, the deviation is visually checked, and the rear heating wire is marked on the member based solely on personal experience or judgment, and then the heating operation is performed.

However, since such a conventional method is made entirely dependent on the skill and know-how of the individual worker, it is difficult to define the tendency, and thus, a serious problem arises in which the standardization of the technology is impossible.

In addition, the conventional method takes a lot of time to transfer new worker skills according to the aging of skilled technicians, thereby causing a serious problem in that overall productivity is greatly reduced.

In particular, under the conventional system, after the procedure S3 is performed, the member is turned over (S4), and a procedure (S5) of forming a transverse/vertical curve is performed. , the ship producer inevitably has to repeatedly perform the 'procedure of turning the member over and heating the back side (that is, the procedure of forming the outgrowth of S3)' there will be no choice but to

Hereinafter, with reference to the accompanying drawings, a more detailed description of the hull curve shell forming system according to the present invention is as follows.

As shown in FIG. 2, the system 100 for forming a hull curved shell according to the present invention is a 'design system 10 providing a member design shape (curved design shape)', 'curved design shape and curved surface measurement 'Curved surface registration system (20) for performing the shape registration procedure', 'Measuring system (30) for providing a member measuring shape (curved measuring shape)', 'Member flipping system for turning over a member (40)' and 'To the member While communicating with the 'heonggok/vertical forming system 50' for forming a hoenggok/vertical curve, a procedure for forming an external longitudinal curve on a member is performed.

For reference, in FIG. 4, the conceptual shape of the transverse/vertical curve formed by the transverse/vertical forming system 50, and the external longitudinal curve formed by the external longitudinal curve forming system 100 for the hull curve shell plate according to the present invention A typical shape is shown.

At this time, as shown in FIG. 3 , the hull hull hull shell plate forming system 100 according to the present invention via the interface module 101 as a medium, 'design system 10 to provide a member design shape ', Bending that communicates with 'measuring system 30 providing a member measuring shape', 'member flipping system 40 for flipping a member', and 'a transverse/vertical curve forming system 50 that forms a transverse/vertical curve on a member' Line extraction module 102, frame data generation module 103, member design shape point coordinate setting module 104, heating point/heating amount calculation module 105, rear heating mechanism 106, rear heating element information generation module (107), the back heating wire information transfer module 108, the back side reheating presence determination module 109, etc. take a closely combined configuration.

As shown in FIG. 5, the bending line extraction module 102 side communicates with the design system 10, loads the member design shape, and then generates a main bending line for the member design shape. procedure will be performed.

Under this procedure, the bending line extraction module 102 generates a main bending line for the design shape of the member after importing the design shape of the member.

The main bending line is extracted by extracting the lowest or highest position from the cross section of both edges of the member and connecting it with a straight line. It is defined as the highest position (the highest point) in the cross section (see FIG. 5).

On the frame data generating module 103 side, as shown in FIGS. 6 and 7 , after extracting the main bending line, N (N=1,2,3) having an interval while being parallel to the left and right about the main bending line ...) frame lines are created, and the XYZ coordinates of the points constituting each frame line are stored as 'member design shape horizontal frame data (FL)', and M (M) having an interval while perpendicular to the main bending line =1,2,3...) frame lines are created and the XYZ coordinates of the points constituting each frame line are stored as 'member design shape vertical frame data (FT)'.

Under this procedure, the frame data generating module 103 side extracts the main bending line and then generates N frame lines at regular intervals (a) parallel to the left and right around the main bending line as shown in FIG. 6 and is defined as FL. The spacing (a) of parallel frame lines can be changed according to the amount of outgoing curve, and the Point coordinates of each frame are stored in the frame data structure.

In addition to the FL data generated in FIG. 6 , M frame lines are generated at regular intervals perpendicular to the main bending line as shown in FIG. 7 and defined as FT. The interval (b) of vertical frame lines can be changed according to the amount of external music, and the Point coordinates of each frame are stored in the frame data structure.

On the member design shape point coordinate setting module 104 side, as shown in FIG. 8, after generating a virtual plane vertically spaced from the member design shape in the Z-axis, each point constituting the virtual plane forms the FL. A procedure of setting the vertical distance e formed with the frame line as the coordinates (Pd,i) of each member design shape point Pd constituting the member design shape is performed.

Under this procedure, the member design shape point coordinate setting module 104 creates an arbitrary plane c spaced perpendicular to the z direction in the 3D CAD shape of the member imported from the design system 10 (see FIG. 8). .

In this case, the arbitrary plane c is parallel to the xy plane of the reference coordinate system and is spaced apart from the origin by a specific distance d in the z direction. The vertical distance e from the frame line FL created in FIG. 6 in an arbitrary plane c parallel to the coordinate system is extracted and stored in the structure. The stored z-coordinate value (e) at each position is regarded as the exogenous curve of the member.

The heating point / heating amount calculation module 105 side communicates with the measurement system 30 to load the member measurement shape and, as shown in FIGS. 9 to 11, 'K (K =1,2,3...) virtual heating points exist, and each member measurement shape point Pm constituting the member measurement shape is rotated and moved by angular deformation of the virtual heating point, so that the corresponding member measurement shape After 'assuming that the coordinates (Pm,i) of the points (Pm) are close to the coordinates (Pd,i) of the member design shape points (Pd)', by changing the number and location of the virtual heating points, As you go, iteratively calculates the Z-direction deviation (dZi) of the coordinates (Pm,i) and the coordinates (Pd,i) to obtain the allowable standard (tol) for all dZi (i=1,2,3...,M). The procedure for calculating the coordinates (Ph,j) of the optimal virtual heating point that is satisfied as the execution heating point coordinates of the member design shape, and calculating each deformation amount of the corresponding optimum virtual heating point as the execution heating amount of the member design shape. will proceed

When there is a heating point in the member, angular deformation occurs by bending the member around the heating point and causing rotational deformation.

When there are several heating points (K) on the initial cross-section or the measured curved cross-section, the point coordinates on the measured curved cross-section frame data are (Pm, i) It rotates and moves closer to the point coordinates (Pd,i) on the curved section frame data (FL) of the design song. That is, the Z-direction (height direction) deviation (dZi) of the point coordinates of each of the M design curved sections and the measured curved section frame data is close to 0 due to the K angular deformations (refer to FIGS. 9 to 11 ).

At this time, the heating point/heating amount calculation module 105 side repeatedly calculates the height deviation (dZi) for each case while changing the number and location of the heating points, and all dZi (i=1,2,…,M) If the tolerance standard (tol) is satisfied with respect to , the heating point coordinates (Ph,j) and the amount of angular deformation at each heating point are stored in the frame data structure of the measured curved section. At this time, the amount of angular deformation is stored in the heating amount column.

The heating point/heating amount calculation module 105 performs this for all the designed curved sections and the measured curved sections, and stores the heating point position coordinates and angular deformation amount for each curved section in each measured curved section frame data structure.

On the other hand, on the side of the rear heating element information generating module 107, as shown in FIGS. 12 to 14, the sequence heating element information including the execution heating point coordinates of the member design shape and the execution heating amount of the member design shape. will proceed

Under this procedure, when the heating point and heating amount are stored in all the curved frame data (FL, FT) on the side of the rear heating wire information generating module 107, the rear heating wire information is generated.

The rules for generating the rear heating wire information are as follows (see FIGS. 12 to 14).

First, the heating points (total F) of the curved section Frame data FL-1 of No. 1 are P11, P12,… Save as P1F. At this time, the X-coordinate of the heating point is stored in the order of the largest. Save P11 as Ph_1 again.

Next, the Frame data FT-1 perpendicular to the bending line is used as it passes through Ph_1. Add the (X,Y,Z) coordinates of Ph_1 and the heating amount to any {Ph_line}. {Ph_line} is a temporary Array that stores the coordinates of the heating points and the amount of heating of each heating point.

Next, for the heating points on the No. 2 to No. N curved section frame data FL, sequentially from the No. 2 curved section Frame data FL-2, it is investigated whether there are heating points within the distance w from the virtual straight line, and if there is an Array Add the coordinates of the heating point and the amount of heating to {Ph_line}.

Next, if the coordinates of the last N-th curved section frame data FL heating point and heating amount are added to {Ph_line}, {Ph_line} is added to the heating line information data structure. After storing the above-described P12 as Ph_1 again and initializing {Ph_line} (deleting all the array contents), the coordinates of Ph_1 and heating amount are added to {Ph_line}. Then repeat the previous process. P13~P1F perform the previous process in the same way.

Next, among the heating points (P3F) created in the curved section Frame data FL-3, when a heating point spaced apart by a distance w from the heating point (P2F) created in the previous FL-2 is created, less than a specific distance value w' On this side, it is regarded as a heating point connected to the heating point (P2F) created in the previous FL, and the heating wire is connected (heating wire on FT-4) and added to the information data structure.

Repeat each step described above. Here, the heating point of Frame data (FL & FT) of curved sections I-1 to N is investigated.

As shown in FIGS. 15 and 16, the rear heating wire information transfer module 108 side communicates with the rear heating wire information generation module 107 to receive the rear heating wire information, and then the received rear heating wire information is described later. By passing it to the heating mechanism 106, it proceeds with a procedure that leads to the formation of a circumflex in the member.

The heating point coordinates and heating amounts for each item of the heating wire information data structure generated through the above-described rear heating wire information generation process become elements constituting one heating wire.

(1) The heating start coordinate of the heating wire: the coordinate of the first heating point (HL_S)

(2) The heating wire ends heating coordinates: the coordinates of the last heating point (HL_F)

(3) Heating rate: Calculate the average value of the heating amounts (angular strain) first. Calculate the heating rate (v_HL) from the average value of the heating amount through the function F that calculates the heating rate from the angular strain. The function F is a function that exists inside the heating program. At this time, if the calculated speed is out of the range of vmin~vmax set in [Heating Limitation Condition], set vmin or vmax as it is. If the heating rate is less than vmin, vmin is designated as the heating rate, and if it is greater than vmax, vmax is designated as the heating rate.

When HL_S, HL_F, v_HL is designated for each item of the heating wire information data structure on the side of the back heating wire information transfer module 108, these values are stored in a separate data file so that the back heating machine device 106 can read them (Fig. 15 and 16).

At this time, if the total number of heating wires stored in the heating wire information data is n, n dat files are created and classified by numbers. File names are designated as [HEATLINE-01.DAT]~[HEATLINE-n.DAT]. When a total of n dat files are converted on the back heating wire information transfer module 108 side, they are transmitted to the back heating machine device 106 at once.

The back heating machine 106 side processes the member according to the back heating wire information, and proceeds with a procedure of forming an outer longitudinal curve on the member.

Under this procedure, the rear heating mechanism 106 side, as shown in FIG. 17, from the rear heating wire information transfer module 108 side [HEATLINE-01.DAT] ~ [HEATLINE-n.DAT] a total of n heating When the work file is received, the heating work is performed sequentially from No. 01 to No. n. From the starting coordinate (HL_S) recorded in each file to the ending coordinate (HL_F), the heating operation is performed at the recorded heating rate (v_HL).

On the back side reheating presence/absence determination module 109 side, as shown in FIGS. 18 to 21, member design shape and member measuring shape After matching , the Z component deviation (dZi) (i=1,2,3... After calculating the average value of the Z component deviation (dZi) (i = 1, 2, 3 ..., M), it is determined whether the calculated average value is less than or equal to the preset tolerance value (dL). Judging, if the average value is less than or equal to the tolerance value (dL), the end of the operation is determined.

Under this procedure, the rear side reheating presence or absence determination module 109 calculates the error of the vertical curve as the error average of the point coordinates on the curved frame data FT, and compares this with the dL (longitudinal tolerance) set in the system 100 to decide whether to complete the work and reheat.

At this time, on the back side reheating presence or absence determination module 109 side, the intersection line passing through the midpoints A and B of both ends of the horizontal curve and the plane including the Z axis, the design surface (member design shape), and the measurement surface (member measurement shape) meet, respectively, design and measure vertical curves Save as section curve geometry, extract Point coordinates and save in Frame data format.

Next, the back side reheating presence/absence determination module 109 additionally stores both end corners of the design vertical curve geometry as the design vertical curve section curve geometry and extracts the point coordinates to generate the design vertical curve section frame data. The coordinates obtained by projecting these Point coordinates on the measurement surface in the Z direction are stored in the measurement vertical cross-section frame data. Through the previous process, three vertical cross-section frame data are created for each design/measurement.

Next, the rear side reheating presence or absence determination module 109 calculates the error average of the vertical cross-section frame data by applying the following process.

(1) After examining the distance from the j-design curved section frame data to the M number of design curved section frame data coordinates on the straight line connecting both end point coordinates (No. 1, M), the largest value is saved as Dmax,j do.

(2) When the deviation of the Z components of the point coordinates on the design curved section and the measured curved section frame data is dZi (i=1,2,…,M), using the equation shown in FIG. 20, from No. 1 Equation is calculated for the Nth design curved section (member design shape) and measured curved section (member measurement shape) frame data.
