Description

TECHNICAL FIELD

[0001] The present application relates to the field of shipbuilding technology, and particularly relates to a positioning method of a cross-shaped fin base reinforcing structure and a ship. BACKGROUND

[0002] In order to improve the stability and safety and reliability of a ship on the sea surface, a fin stabilizer is usually installed on the two sides of the bilge of the ship, and the action force of water flow on the fin is used to reduce the rolling of the ship.

[0003] At present, the fin stabilizer can be divided into two categories: retractable fin stabilizers and fixed fin stabilizers. The retractable fin stabilizer is flexible in operation, and the underwater fin part can be retracted into the ship body profile when passing through a relatively narrow channel, entering a port, or in a reef area. However, the retractable fin stabilizer has a complex structure, high cost and high maintenance cost, and is therefore mostly used on luxury cruise ships and special marine equipment. The fixed fin stabilizer refers to a fin structure that extends out of the ship body profile underwater and cannot be folded back into the ship body profile. The fin structure is fixed underwater. This type of fin stabilizer structure is relatively simple, and has low cost, low installation cost and low maintenance cost, and stable and reliable transverse rolling effect. Therefore, many ships that have requirements for navigation and control of cost will choose the fixed fin stabilizer.

[0004] The fin base of the fixed fin stabilizer is an important part of the connection between the fin stabilizer and the ship body. Because the fin stabilizer is subjected to a very large force underwater, the fin base needs to have a reinforcing structure for fixation and support. According to the connection form of the fin base and the ship body, the reinforcing structure of the fin base and the ship body can be provided in a cross shape and a cross shape. However, in order to improve the stability and reliability of the fin base force, the cross-shaped fin base reinforcing structure is widely used at present.

[0005] When installing the cross-shaped fin base reinforcing structure, the outer plate of the bilge of the ship body has a certain curvature, which causes the projection of the axis of the fin base on the YZ plane to have an angle θ between the XY horizontal plane, and the projection on the XZ plane to have an angle γ between the YZ plane. Therefore, it is difficult to accurately position the reinforcing structure with both transverse and longitudinal angles of the axis of the fin base.

[0006] In the prior art, the fin base model is usually loaded and referenced in the ship design software, and the model of the corresponding cross-shaped reinforcing structure is built. The on-site installation stage of the reinforcing structure is the same as the installation stage of the fin base (mostly the shipbuilding stage). At the same time, a margin is added at the connection end of the fin base to prevent the reinforcing structure from being short, and then the margin part is cut off and trimmed when the reinforcing structure is installed and positioned in the shipbuilding stage.

[0007] However, the method in the prior art has the following disadvantages:

[0008] 1. Due to the limitation of the ship design software: the outfitting model positioning is not accurate, especially for the longitudinal angle γ. The reason is that when the outfitting fin base model is placed in the design software, the θ angle is made first and then the γ angle is made, which is not accurate when the technical protocol of the equipment specifies the intersection of the fin base axis and the theoretical line of the outer plate, resulting in inaccurate reference of the outfitting fin base model.

[0009] 2. Inaccurate modeling will lead to an increase in interface allowance to ensure that the X-shaped fin base reinforcement structure is not short, and cutting the allowance during installation will increase the on-site workload and reduce work efficiency.

[0010] 3. The fin base reinforcement structure is installed during the shipbuilding stage, which not only increases the workload of the shipbuilding stage and reduces work efficiency, but also increases the ship launching cycle and costs.

[0011] Therefore, it is urgent to design a positioning method for X-shaped fin base reinforcement structure and a ship to solve the above technical problems. SUMMARY

The reinforcing surface is determined in a three-point positioning mode. Since the axis of the fin seat is the intersection line of each cross fin seat reinforcing surface, the coordinates of two points on the axis of the fin seat are solved first, then a point in each cross fin seat reinforcing surface is solved, and finally the position of each cross fin seat reinforcing surface is positioned by the three-point positioning mode. In other words, the operator can solve the coordinates of three points of each cross fin seat reinforcing surface according to the technical parameters in the fin stabilizer equipment data or technical agreement, and the position of each cross fin seat reinforcing surface is positioned by the three-point positioning mode. Therefore, the accurate position of the cross fin seat reinforcing structure can be given in the design stage, the cross fin seat reinforcing structure can be installed in the section stage, the workload in the shipbuilding stage is reduced, the shipbuilding cycle is shortened, and the cost is saved. Meanwhile, the positioning accuracy of the cross fin seat reinforcing structure is improved, the workload of cutting the excess amount is reduced, the problem that the cross fin seat reinforcing structure and the fin seat equipment connection port need to be cut is avoided, the work efficiency is improved, and the cost is saved.

[0057] The application provides a ship, which can improve work efficiency, shorten a shipbuilding cycle, and save cost. BRIEF DESCRIPTION OF DRAWINGS

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0080] like Figures 1-3 As shown, when installing the star-shaped fin support reinforcement structure 400, the curvature of the outer bilge plating causes an angle θ between the projection of the fin support 100's axis 200 on the YZ plane and the XY horizontal plane, and an angle γ between its projection on the XZ plane and the YZ plane. Therefore, it is difficult to accurately position the reinforcement structure for which the fin support 100's axis 200 has both lateral and longitudinal angles.

[0081] like Figures 4-12 As shown, this embodiment provides a positioning method for the cross-shaped fin support reinforcement structure 400, which can improve positioning accuracy; reduce the workload of trimming excess material at the installation site and improve work efficiency; reduce the workload of the shipyard assembly stage, shorten the ship launching cycle, and save costs.

[0082] Specifically, the positioning method of the star-shaped fin reinforcement structure 400 mainly includes:

[0083] Obtain the coordinates of two points at different positions on the axis 200 of the fin seat 100;

[0084] Obtain the coordinates of a point on the reinforcing surface of each star-shaped fin;

[0085] The coordinates of two points on the axis 200 and the coordinates of one point in each cross-shaped fin reinforcement surface are used to form a three-point coordinate system, and the position of each cross-shaped fin reinforcement surface is located using the three-point coordinate system.

[0086] In this embodiment, the positioning method of the star-shaped fin support reinforcement structure 400 can determine the accurate position of each star-shaped fin support reinforcement surface based on the design parameters of the anti-roll fin. The reinforcement surface is determined by positioning a plane using three points. Since the axis 200 of the fin support 100 is the intersection line of each star-shaped fin support reinforcement surface, for convenience, the coordinates of two points on the axis 200 of the fin support 100 can be calculated first, then the coordinates of one point on each star-shaped fin support reinforcement surface can be calculated, and finally, the position of each star-shaped fin support reinforcement surface can be located using the three-point coordinates.

[0087] Therefore, the operator can obtain the coordinates of the three points of each herringbone fin base reinforcing surface according to the technical parameters in the fin device data or technical agreement, and locate the position of each herringbone fin base reinforcing surface through the mathematical theorem of determining a plane by three points. Thus, the accurate positioning of the herringbone fin base reinforcing surface can be given in the design stage without waiting for the reference of the fin device in the total assembly stage of the berth, but only by calculating the coordinates of the three points in each herringbone fin base reinforcing surface according to the technical parameters in the device data or technical agreement, so that the herringbone fin base reinforcing structure 400 can be installed in the staging stage, reducing the workload in the total assembly stage of the berth, shortening the launching period of the ship, and saving costs. At the same time, the positioning accuracy of the herringbone fin base reinforcing structure 400 can be improved, the workload of cutting the excess amount in the installation site can be reduced, the problem of needing to add the excess amount of the connection port of the herringbone fin base reinforcing structure 400 and the fin device can be avoided, the work efficiency can be improved, and the purpose of saving costs can be achieved.

[0088] In addition, the positioning method of the herringbone fin base reinforcing structure 400 in the embodiment is to use the intersection of each herringbone reinforcing section on the axis line 200 of the fin 100, in other words, each point on the axis line 200 of the fin 100 is a point on each herringbone fin base reinforcing surface. Thus, when obtaining the coordinates of the three points of each herringbone fin base reinforcing surface, two points on the axis line 200 of the fin 100 can be used in common, so that only one point on each herringbone fin base reinforcing surface that is not on the axis line 200 needs to be solved to complete the accurate positioning of the position of the herringbone fin base reinforcing surface, thereby simplifying the steps, improving the work efficiency, and saving the labor cost.

[0089] As shown in Figure 4 In the embodiment, the step of obtaining the coordinates of the two points at different positions on the axis line 200 of the fin 100 includes:

[0090] obtaining the coordinates A(FR48, a1, b1) of the intersection point of the axis line 200 of the fin 100 and the theoretical line 300 of the outer plate;

[0091] obtaining the angle θ between the projection line of the axis line 200 of the fin 100 on the YZ plane and the XY plane; that is, the angle between the projection line of the axis line 200 of the fin 100 on the YZ plane (X=FR48 transverse section) and the XY horizontal plane is θ;

[0092] obtaining the angle γ between the projection line of the axis line 200 of the fin 100 on the XZ plane and the YZ plane; that is, the angle between the projection of the axis line 200 of the fin 100 on the XZ plane and the YZ plane (X=FR48 transverse section) is γ.

[0093] The step of obtaining the coordinates of the two points at different positions on the axis line 200 of the fin 100 includes:

[0094] Take any point B' on the projection line of the axis 200 of fin seat 100 onto the YZ plane (X = FR48 cross section). The perpendicular line from point B' intersects the XY plane (horizontal plane) at a height equal to that of point A at point A'; that is, the perpendicular line from point B' intersects the extension of point A on the XY plane at A'. The horizontal line of point B' intersects the XZ plane (… Figure 4 The longitudinal section VIEW-A is at point B;

[0095] The half-width Y value and height Z value of point B are the same as those of point B'. The X value in the ship length direction is the X value of point B” plus h1*tanγ. That is, the coordinates of point B on the axis 200 of fin seat 100 are (FR48+h1*tanγ, a1-h1 / tanθ, b1+h1), where h1≠0.

[0096] In this way, the coordinates of the intersection point A of the axis 200 of the fin seat 100 and the theoretical line 300 of the outer plate can be determined, as well as the coordinates of another point B on the axis 200 of the fin seat 100.

[0097] In this embodiment, along the axis 200 of the fin seat 100, the star-shaped fin seat reinforcement structure 400 has at least four cross-sections, and the at least four cross-sections are evenly arranged about the axis 200.

[0098] For example, such as Figures 5-6 As shown, along the axis 200 of the fin seat 100, the star-shaped fin seat reinforcement structure 400 has a first section, a second section, a third section and a fourth section, wherein the first section and the second section are perpendicular to each other, and the third section and the fourth section are perpendicular to each other.

[0099] It should be noted that the first section is along... Figure 6 The cross-section along direction 1-1 is the second cross-section. Figure 6 The third section is along the 2-2 direction. Figure 6 The fourth section is along the 3-3 direction. Figure 6 The cross-section along the 4-4 direction.

[0100] The following section describes the steps for determining the coordinates of a point on the reinforcing surface of each star-shaped fin.

[0101] like Figure 7 As shown, the step of obtaining the coordinates of a point in each of the cross-shaped fin support reinforcing surfaces in this embodiment includes obtaining the coordinates of any point C outside the axis 200 on the first cross-section. Specifically, the step of obtaining the coordinates of any point C outside the axis 200 on the first cross-section includes:

[0102] In the first profile, the X coordinates of all points at the same height as point A are the same as the X coordinates of point A.

[0103] The height of the point C is the same as the height of the point A.

[0104] The coordinates of the point C are calculated as (FR48, a1-y1, b1), wherein y1≠0.

[0105] That is, the coordinates of any point C outside the axis 200 on the 1-1 profile (the first profile) are solved. Figure 6 Since the X coordinates of the points on the first profile that are the same height as the point A are the same as the X coordinate of the point A, the height of the point C is the same as the height of the point A for the convenience of calculation. The Y coordinate value of the point C is solved, and the coordinates of the point C are calculated as (FR48, a1-y1, b1), wherein y1≠0. That is, the 1-1 profile is positioned by three points, which are the point A (FR48, a1, b1), the point B (FR48+h1*tanγ, a1-h1 / tanθ, b1+h1), h1≠0, and the point C (FR48, a1-y1, b1), y1≠0. The actual position of the Mi-shaped fin base reinforcing surface in the first profile direction is accurately positioned by the mathematical theorem that a plane is determined by three points A, B and C.

[0106] As shown in FIG. 1, Figure 8 the step of obtaining the coordinates of any point D outside the axis 200 on the second profile includes:

[0107] In the second profile, the Y coordinates of the points that are the same height as the point A are the same as the Y coordinate of the point A.

[0108] The height of the point D is the same as the height of the point A.

[0109] The coordinates of the point D are calculated as (FR48+x2, a1, b1), wherein x2≠0.

[0110] That is, the coordinates of any point D outside the axis 200 on the 2-2 profile (the second profile) are solved. Figure 6 Since the Y coordinates of the points on the second profile that are the same height as the point A are the same as the Y coordinate of the point A, the height of the point D is the same as the height of the point A for the convenience of calculation. The X coordinate value of the point D is solved, and the coordinates of the point D are calculated as (FR48+x2, a1, b1), wherein x2≠0. That is, the 2-2 profile is positioned by three points, which are the point A (FR48, a1, b1), the point B (FR48+h1*tanγ, a1-h1 / tanθ, b1+h1), h1≠0, and the point D (FR48+X2, a1, b1), X2≠0. The actual position of the Mi-shaped fin base reinforcing surface in the second profile direction is accurately positioned by the mathematical theorem that a plane is determined by three points A, B and D.

[0111] As shown in FIG. 1, Figures 9-10As shown, the step of obtaining the coordinates of a point in each of the cross-shaped fin reinforcement surfaces in this embodiment includes obtaining the coordinates of any point E outside the axis 200 on the third cross-section. Specifically, the step of obtaining the coordinates of any point E outside the axis 200 on the third cross-section includes:

[0112] Take any point E' on the first cross section, and obtain the coordinates of point E' on the YZ plane as (FR48, a1-y3*sinθ, b1-y3*cosθ), where y3≠0;

[0113] In the XZ plane, the Y coordinate of point E' is the same as the Y coordinate of point E;

[0114] The coordinates of point E are calculated to be (FR48+x3*cosγ, a1-y3*sinθ, b1-y3*cosθ-x3*sinγ), where x3=y3≠0.

[0115] In other words, solve Figure 9 The coordinate E of any point outside the centerline 200 on section 3-3 (the third section) is given. For ease of calculation, the coordinates are set as follows: Figure 9 The VIEW-B profile passes through points A, E', and E. The coordinates of point E on the third profile are indirectly determined by solving for the coordinates of E'. Specifically, the coordinates of point E' are first determined on the X = FR48 cross-section (YZ plane) as (FR48, a1 - y3*sinθ, b1 - y3*cosθ), where y3 ≠ 0. Then, the coordinates of point E are determined in the VIEW-A view, which has the same Y-value as point E'. The calculated coordinates of point E are (FR48 + x3*cosγ, a1 - y3*sinθ, b1 - y3*cosθ - x3*sinγ), where x3 = y3 ≠ 0. That is, the three points for locating the section in section 3-3 are: point A (FR48, a1, b1); point B (FR48+h1*tanγ, a1-h1 / tanθ, b1+h1), h1≠0; and point E (FR48+x3*cosγ, a1-y3*sinθ, b1-y3*cosθ-x3sinγ), x3=y3≠0. Furthermore, by using the mathematical theorem that points A, B, and E determine a plane, the actual position of the star-shaped fin reinforcement surface in the direction of the third section is precisely located.

[0116] like Figures 11-12 As shown, the step of obtaining the coordinates of a point in each of the cross-shaped fin reinforcement surfaces in this embodiment includes obtaining the coordinates of any point F outside the axis centerline 200 on the fourth cross-section. Specifically, the step of obtaining the coordinates of any point F outside the axis centerline 200 on the fourth cross-section includes:

[0117] Take any point F' on the first cross section, and obtain the coordinates of point F' on the YZ plane as (FR48, a1-y4*sinθ, b1-y4*cosθ), where y4≠0;

[0118] In the XZ plane, the Y coordinate of point F' is the same as the Y coordinate of point F;

[0119] The coordinates of point F are calculated to be (FR48-x4*cosγ, a1-y4*sinθ, b1-y4*cosθ+x4*sinγ), where x4=y4≠0.

[0120] In other words, solve Figure 11 The coordinate F of any point outside the centerline 200 on section 4-4 (the fourth section). For ease of calculation, set... Figure 11 The VIEW-B profile passes through points A, F', and F. The coordinates of point F on the fourth profile are indirectly determined by solving for the coordinates of F'. Specifically, the coordinates of F' are first determined on the X = FR48 cross-section (YZ plane) as (FR48, a1 - y4*sinθ, b1 - y4*cosθ), where y4 ≠ 0. Then, the coordinates of point F are determined in the VIEW-A view, which has the same Y-value as point F'. The calculated coordinates of point F are (FR48 - x4*cosγ, a1 - y4*sinθ, b1 - y4*cosθ + x4*sinγ), where x4 = y4 ≠ 0. That is, the three points for locating section 4-4 are: point A (FR48, a1, b1); point B (FR48+h1*tanγ, a1-h1 / tanθ, b1+h1), h1≠0; and point F (FR48-x4*cosγ, a1-y4*sinθ, b1-y4*cosθ+x4*sinγ), x4=y4≠0. Furthermore, by using the mathematical theorem that points A, B, and F determine a plane, the actual position of the star-shaped fin reinforcement surface in the fourth section direction is precisely located.

[0121] It is understandable that when finding point C in section 1-1, it is taken at the same height as point A, and the X-coordinate of point C is the same as that of point A. Therefore, only the Y-coordinate of point C needs to be chosen arbitrarily (but not the same as the Y-coordinate of point A). When finding point D in section 2-2, it is taken at the same height as point A, and the Y-coordinate of point D is the same as that of point A. Therefore, only the X-coordinate of point D needs to be chosen arbitrarily (but not the same as the X-coordinate of point A). When finding point E in section 3-3, an auxiliary point E' is used to make points A, E', and E on the same plane, and then the coordinates of point E are obtained by two projections. When finding point F in section 4-4, an auxiliary point F' is used to make points A, F', and F on the same plane, and then the coordinates of point F are obtained by two projections.

[0122] Compared with the model of the H-shaped fin base reinforcing structure 400 built in the prior art fin base model, the positioning method of the H-shaped fin base reinforcing structure 400 in the embodiment has higher accuracy, and can improve the accuracy of positioning the H-shaped fin base reinforcing structure 400. No allowance needs to be added at the fin base equipment connecting end, reducing the work of aligning and cutting the allowance of the reinforcing structure on site. The fin base equipment installation is not needed to wait for the installation of the H-shaped fin base reinforcing structure 400, and the process of installing the H-shaped fin base reinforcing structure 400 can be advanced to the installation in the segmentation stage, reducing the work load in the berth stage, shortening the ship launching period, and saving costs.

[0123] The embodiment also provides a ship, which comprises a hull and a fin stabilizer connected with the hull through the H-shaped fin base reinforcing structure 400, and the H-shaped fin base reinforcing structure 400 is positioned by using the positioning method of the H-shaped fin base reinforcing structure 400.

[0124] Since the ship is manufactured by using the positioning method of the H-shaped fin base reinforcing structure 400, work efficiency can be improved, the ship launching period can be shortened, and the purpose of saving costs can be achieved.
