Description

Technical Field

[0001] This invention relates to the technical field of ship design and manufacturing, and in particular to a method, apparatus, equipment and storage medium for measuring the angle of a double-tilt plate. Background Technology

[0002] Ship structures are complex, containing many inclined structures, especially those with double inclination. During the fabrication of ship plates, when angled plates with double inclination are present, they need to be processed by corner rolling. This involves applying appropriate force and pressure to plastically deform the plate along the desired angle, changing its angle and shape. Determining the angle direction for corner rolling is one of the key steps in processing angled plates.

[0003] Currently, the angle of corner rolling is calculated by taking the angle of the cross-sectional profile of the corner plate and using it as the basis for processing the corner plates of ships. However, double-tilted corner plates have two-way tilt angles and generally only have one basic cross-sectional profile. Using the angle of the cross-sectional profile of the corner plate as the processing basis results in low accuracy of the angle direction in corner rolling, more deformation of the corner plate, increased plate processing difficulty, higher damage rate of the corner plate, and increased production cost of corner plate processing. Summary of the Invention

[0039] Example 1

[0040] Figure 1 This is a flowchart of an angle measurement method for a double-tilted angle plate according to Embodiment 1 of the present invention. This embodiment is applicable to the angle measurement of double-tilted angle plates. The method can be executed by an angle measuring device for double-tilted angle plates, which can be implemented in hardware and / or software and can be configured in an electronic device. Figure 1 As shown, the method includes:

[0041] Step 101: Model the angled plate component of the ship that has a bidirectional inclined structure to obtain the rib-shaped line drawing.

[0042] To ensure safe navigation at sea, ships must possess a certain level of structural strength and stability. Ship structures are complex, with many inclining structures, especially bidirectional inclining structures. Bidirectional inclining structures are typically implemented at the bow and stern of the hull. A bidirectional inclining structure is a structural design in which the hull has a certain inclining angle in both the longitudinal and transverse directions. It is mainly used in certain special types of ships, such as high-speed ships and roll-on / roll-off ships. When producing the plates for such ships, the plates need to be rolled. Rib profile drawings are diagrams that show the shape of the hull rib profiles, the arrangement of the outer plate joints, and the layout of the decks, platforms, and various longitudinal components. They can intuitively show the structural layout of the hull and the position of the components.

[0043] During production design, the necessary data is obtained from the design drawings, including the ship's geometry, dimensions, structural layout, and other relevant parameters. The obtained design data is processed, and a ship model is built based on the design data. This results in a model of the angled plate with a bidirectional inclined structure. The rib-shaped line drawing corresponding to the angled plate is then drawn. The angled plate has a certain inclination angle in both the horizontal and vertical directions. The rib-shaped line drawing has an original near-center line, an original angle line, and an original top line. The original near-center line refers to the longitudinal edge closest to the center in the rib-shaped line drawing. The original angle line refers to the line segment corresponding to the angle in the rib-shaped line drawing. The original top line refers to the longitudinal edge closest to the top in the rib-shaped line drawing.

[0044] For example, a rib-shaped line drawing is as follows: Figure 2a As shown, its vertical view is as follows Figure 2b As shown, the horizontal view is as follows Figure 2c As shown, F4, F5, F6, F7, F8, and F9 are rib lines, the original upper edge is the upper longitudinal edge, the original near-center line is the lower longitudinal edge, rib lines F4 and F9 are two transverse edges, and Y is the projection angle of the double-angle plate in the rib line diagram, that is, the angle of the rib line.

[0045] Step 102: Project the original midline, the original angle line, and the original top line vertically into the top view to obtain the vertical midline, the vertical angle line, and the vertical top line.

[0046] Perform vertical projection operations on the original midline, original angle line, and original top line respectively, project them along the vertical direction, and represent them in the top view of the angle plate to obtain the corresponding vertical midline, vertical angle line, and vertical top line. Vertical projection refers to the process of projecting an object or graphic onto a plane along the vertical direction.

[0047] In one example, such as Figure 3 As shown, the vertical near-center line F is obtained by vertically projecting the original near-center line, the vertical angle line K is obtained by vertically projecting the original angle line, and the vertical top line E is obtained by vertically projecting the original top line.

[0048] Step 103: In the top view, project the vertical near-center line, the vertical angle line, and the vertical top line horizontally onto the horizontal near-center line, the horizontal angle line, and the horizontal top line, respectively.

[0049] The vertical near-center line, vertical angle line, and vertical top line in the top view of the angled plate are projected horizontally to obtain the corresponding horizontal near-center line, horizontal angle line, and horizontal top line. Horizontal projection refers to the process of projecting an object or graphic onto a plane along the horizontal direction.

[0050] In one embodiment of the present invention, step 103 may include the following steps:

[0051] Step 1031: Generate a baseline parallel to the vertical angle line in the top view.

[0052] In the top view of the angled plate, draw a line segment parallel to the vertical angled line as a reference line, with the reference line located to the left of the vertical near-center line.

[0053] Step 1032: Query the first pose when the original midline, the original angle line, and the original top line are projected perpendicularly.

[0054] The angled plate is a single unit, and its overall orientation is fixed during projection. The orientations of its original midline, original angle line, and original top edge are also fixed. These orientations can be characterized using geometric information. The orientations of the original midline, original angle line, and original top edge during vertical projection are considered the first orientation.

[0055] For example, the first posture includes a first height value of the first near endpoint in the original midline, a fourth height value of the second near endpoint, a second height value of the first fold endpoint in the original fold line, a fifth height value of the second fold endpoint, a third height value of the first upper endpoint in the original upper line, and a sixth height value of the second upper endpoint.

[0056] The first height value refers to the vertical distance from the first proximal endpoint of the original midline to the X-axis; the second height value refers to the vertical distance from the first bend endpoint of the original angle line to the X-axis; the third height value refers to the vertical distance from the first upper endpoint of the original top line to the X-axis; the fourth height value refers to the vertical distance from the second proximal endpoint of the original midline to the X-axis; the fifth height value refers to the vertical distance from the second bend endpoint of the original angle line to the X-axis; and the sixth height value refers to the vertical distance from the second upper endpoint of the original top line to the X-axis.

[0057] Step 1033: While maintaining the first posture, project the vertical near-center line, vertical angle line, and vertical top line onto the horizontal near-center line, horizontal angle line, and horizontal top line through the baseline.

[0058] A baseline parallel to the vertical bend line is generated. The two endpoints of the vertical near-center line, vertical bend line, and vertical top line are projected perpendicularly to the baseline. The projection distances are the perpendicular distances from the two endpoints of the vertical near-center line, vertical bend line, and vertical top line to the X-axis, respectively. The corresponding endpoints of the projected vertical near-center line, vertical bend line, and vertical top line are connected to obtain the horizontal near-center line, horizontal bend line, and horizontal top line. The horizontal near-center line, horizontal bend line, and horizontal top line obtained after projection through the baseline also maintain the same initial orientation as the vertical near-center line, vertical bend line, and vertical top line.

[0059] In the specific implementation, the first and second near endpoints of the original midline are vertically projected to the third and fourth near endpoints of the vertical midline, respectively, and the first and second upper endpoints of the original upper edge are vertically projected to the third and fourth upper endpoints of the vertical upper edge, respectively.

[0060] For the vertical near-center line, the first reference line and the second reference line perpendicular to the baseline can be generated through the third and fourth near endpoints of the vertical near-center line, respectively.

[0061] Take the fifth near endpoint on the first reference line, such that the distance between the fifth near endpoint and the baseline is equal to the first height value.

[0062] Take the sixth near endpoint on the second reference line, so that the distance between the sixth near endpoint and the baseline is equal to the fourth height value.

[0063] Connect the fifth and sixth proximal endpoints to obtain the horizontal midline.

[0064] For a vertical bend line, a third reference line and a fourth reference line perpendicular to the baseline can be generated through the third and fourth bend endpoints of the vertical bend line.

[0065] Take the fifth bend endpoint on the third reference line, so that the distance between the fifth bend endpoint and the baseline is equal to the second height value.

[0066] Take the sixth bend endpoint on the fourth reference line, so that the distance between the sixth bend endpoint and the baseline is equal to the fifth height value.

[0067] Connect the fifth and sixth bend endpoints to obtain a horizontal bend line.

[0068] For the vertical top line, the fifth and sixth reference lines, which are perpendicular to the baseline, can be generated through the third and fourth top endpoints of the vertical top line, respectively.

[0069] Take the fifth upper endpoint on the fifth reference line, so that the distance between the fifth upper endpoint and the baseline is equal to the third height value.

[0070] Take the sixth upper endpoint on the sixth reference line, so that the distance between the sixth upper endpoint and the baseline is equal to the sixth height value.

[0071] Connect the fifth and sixth upper endpoints to obtain the horizontal upper edge.

[0072] While maintaining the first posture, namely the first height value of the first near endpoint and the fourth height value of the second near endpoint in the original near-center line, the second height value of the first bend endpoint and the fifth height value of the second bend endpoint in the original bend line, and the third height value of the first upper endpoint and the sixth height value of the second upper endpoint in the original upper edge line remain unchanged, and with the height values ​​of each endpoint unchanged, the endpoints of corresponding heights are drawn on the left side of the baseline, using the vertical near-center line, the vertical bend line and the vertical upper edge line as the standard, and the endpoints of each line segment are connected to obtain the horizontal near-center line, the horizontal bend line and the horizontal upper edge line.

[0073] In one example, such as Figure 3As shown, a baseline M parallel to the vertical bend line K is generated. The vertical distance H1 from the first near endpoint of the original midline to the X-axis is the first height value; the vertical distance H2 from the first bend endpoint of the original bend line to the X-axis is the second height value; the vertical distance H3 from the first top endpoint of the original top line to the X-axis is the third height value; the vertical distance H4 from the second near endpoint of the original midline to the X-axis is the fourth height value; the vertical distance H5 from the second bend endpoint of the original bend line to the X-axis is the fifth height value; and the vertical distance H6 from the second top endpoint of the original top line to the X-axis is the sixth height value. The two endpoints of the vertical midline F, the vertical bend line K, and the vertical top line E are projected perpendicularly to the baseline, with projection distances of H1, H2, H3, H4, H5, and H6, respectively. The corresponding endpoints of the projected vertical midline F, the vertical bend line K, and the vertical top line E are then connected to obtain the horizontal midline c, the horizontal bend line k, and the horizontal top line e.

[0074] Step 104: Construct the angle between the normal planes of the angled plate based on the vertical near-center line, the vertical angled line, the vertical top line, the horizontal near-center line, the horizontal angled line, and the horizontal top line.

[0075] By determining the relative relationships between the vertical near-center line, the vertical fold line, and the vertical top edge line and the horizontal near-center line, and the horizontal fold line and the horizontal top edge line, the normal angle of the fold line of the folded plate is constructed.

[0076] The original angled line has an inclination angle in both the vertical and horizontal directions. By vertical projection, a baseline parallel to the vertical angled line is obtained, and the inclination angle of the original angled line in the vertical direction is revealed. By horizontal projection, the inclination angle of the original angled line in the horizontal direction is presented. By obtaining the inclination angles in both directions, the true normal plane of the original angled line is obtained, and then the angle of inclination is calculated.

[0077] In one embodiment of the present invention, step 104 may include the following steps:

[0078] Step 1041: Generate the first normal line among the horizontal near-center line, the horizontal angle line, and the horizontal top edge line.

[0079] Generate the first normal line perpendicular to the horizontal angle line.

[0080] Generate a line segment perpendicular to the horizontal bend line. This line segment passes through the horizontal near-center line, the horizontal bend line, and the horizontal top edge line, and intersects the horizontal near-center line, the horizontal bend line, and the horizontal top edge line at one point each. This line segment is represented as the first normal line.

[0081] Mark the point where the first normal line intersects the horizontal top line as the first target point.

[0082] There is only one point where the first normal line intersects the horizontal upper edge line, which is the first target point.

[0083] Mark the point where the first normal line intersects the horizontal angle line as the second target point.

[0084] There is only one point where the first normal line intersects the horizontal angle line, which is the second target point.

[0085] Mark the point where the first normal line intersects the horizontal near-center line as the third target point.

[0086] There is only one point where the first normal line intersects the horizontal near-center line, which is the third target point.

[0087] For example, such as Figure 3 As shown, a first normal line L is generated that is perpendicular to the horizontal angle line. The point where the first normal line intersects with the horizontal top line is the first target point a. The point where the first normal line intersects with the horizontal angle line is the second target point b. The point where the first normal line intersects with the horizontal near-center line is the third target point c.

[0088] Step 1042: Map the first normal line back to the vertical near-center line, the vertical angle line, and the vertical top edge line to obtain the second normal line.

[0089] Map the point where the first normal line intersects with the horizontal near-center line, the horizontal angle line, and the horizontal top line onto the vertical near-center line, the vertical angle line, and the vertical top line in the top view.

[0090] The reference line is used to project the vertical near-center line, vertical angle line, and vertical top line horizontally onto the horizontal near-center line, horizontal angle line, and horizontal top line.

[0091] Generate a first target line perpendicular to the baseline through the first target point, and mark the point where the first target line intersects with the vertical upper edge as the first reference point.

[0092] Generate a second target line perpendicular to the baseline through the second target point, and mark the point where the second target line intersects the vertical angle line as the second reference point.

[0093] Generate a third target line perpendicular to the baseline through the third target point, and mark the point where the third target line intersects the vertical near-center line as the third reference point.

[0094] Connect the first reference point, the second reference point, and the third reference point in sequence to form the second normal line.

[0095] Confirm the baseline used in the above horizontal projection operation, draw perpendicular lines through the three target points, and intersect them with the corresponding vertical near-center line, vertical angle line, and vertical top line to obtain the first reference point, the second reference point, and the third reference point. Connect the first reference point, the second reference point, and the third reference point to obtain the second normal line.

[0096] For example, such as Figure 3 As shown, a baseline M parallel to the vertical angle line K is generated. A first target line perpendicular to the baseline M is generated through the first target point a, and the point intersecting with the vertical upper edge line is the first reference point A. A second target line perpendicular to the baseline M is generated through the second target point b, and the point intersecting with the vertical angle line is the second reference point B. A third target line perpendicular to the baseline M is generated through the third target point c, and the point intersecting with the vertical near-center line is the third reference point C. Connecting points A, B, and C forms the second normal line ABC.

[0097] Step 1043: Query the second attitude when the second normal line is horizontally projected.

[0098] The poses of the vertical near-center line, vertical angle line, and vertical top line during horizontal projection are obtained as the second pose. The second pose includes the first distance value between the third reference point and the baseline, the second distance value between the second reference point and the baseline, and the third distance value between the first reference point and the baseline. The distance value represents the vertical distance from the reference point to the baseline.

[0099] For example, such as Figure 3 As shown, the vertical distance h1 from the third reference point C to the baseline M is the first distance value, the vertical distance h2 from the second reference point B to the baseline M is the second distance value, and the vertical distance h3 from the first reference point A to the baseline M is the third distance value.

[0100] Step 1044: Generate the angle between the normal plane of the bend line of the bend plate so that the angle between the normal plane of the bend line maintains a second orientation relative to the first normal plane.

[0101] When the angle between the bend line and the normal plane can maintain a second posture relative to the first normal plane, obtain the angle between the bend line and the normal plane of the current bend plate.

[0102] In a practical implementation, a third normal line parallel to the first normal line can be generated.

[0103] The first normal line is translated to generate a parallel line segment located below the first normal line, which serves as the third normal line.

[0104] Generate a first feature point, a second feature point, and a third feature point, wherein the first feature point and the third normal line maintain a first distance value, the second feature point and the third normal line maintain a second distance value, and the third feature point and the third normal line maintain a third distance value.

[0105] With lengths of the first distance value, the second distance value, and the third distance value, draw line segments on the third normal plane that are respectively at distances of the first distance value, the second distance value, and the third distance value from the third normal plane. The outer endpoints of these line segments are the first feature point, the second feature point, and the third feature point.

[0106] Connect the first feature point, the second feature point and the third feature point in sequence to form the angle between the normal plane of the fold line of the folded plate.

[0107] Connect the first feature point, the second feature point, and the third feature point, and use the angle formed by them as the angle between the normals of the fold line of the folded plate.

[0108] For example, such as Figure 3 As shown, a third normal line N parallel to the first normal line L is generated. Using the first distance value h1, the second distance value h2, and the third distance value h3 as lengths, line segments with distances h1, h2, and h3 from the third normal line N are drawn on the third normal line N, respectively, to obtain three external endpoints, namely the first feature point R, the second feature point O, and the third feature point G. Connecting points R, O, and G, the angle ROG is the included angle of the normal line of the bend.

[0109] Step 105: Measure the angle between the normal surfaces of the bend lines, and use it as the bend angle of the bend plate.

[0110] The degree measure of the included angle of the folded corner surface is the folding angle of the folded plate. The folding angle is used as the basis for the corner rolling process to process the folded plate.

[0111] For example, such as Figure 4 As shown, draw a perpendicular line X, making it perpendicular to the rib line. Using the actual rib spacing as the interval, draw auxiliary rib lines F4, F5, F6, F7, F8, and F9 parallel to the perpendicular line X. Project the intersection of the perpendicular line X and the rib line perpendicularly onto the auxiliary rib lines, and connect all the perpendicular points sequentially to obtain lengths X1, X2, X3, X4, and X5. Using the lengths X1, X2, X3, X4, and X5 as the interval, draw auxiliary rib lines F4, F5, F6, F7, F8, and F9 parallel to the rib line. Project the top edge point and corner point of the rib line perpendicularly onto the auxiliary rib lines, and connect the top edge point and corner point sequentially. This unfolds the top fold of the corner plate. Similarly, the near-center fold can also be unfolded. Loosen and unfold the two fold shapes of the corner plate, and join the two unfolded folds with the corner line. The unfolded shape of the plate is as follows: Figure 5 As shown, its actual sample of the rolled corner is as follows: Figure 6 As shown.

[0112] In this embodiment of the invention, a model is created for a bi-directional inclined angled plate in a ship, yielding a rib-shaped line drawing. The original near-center line, original angled line, and original top edge of the rib-shaped line drawing are vertically projected onto a top view, resulting in a vertical near-center line, vertical angled line, and vertical top edge. In the top view, these lines are horizontally projected onto a horizontal near-center line, horizontal angled line, and horizontal top edge. Based on these lines, the angle between the normal planes of the angled plates is constructed. Finally, the degree measure of this angle is taken as the angle of the angled plate. Using the normal angle of the bi-directional inclined angled plate as the processing basis provides an accurate reference for the corner rolling process, reducing the processing difficulty of the bi-directional inclined angled plate, effectively improving the layout and development efficiency of the bi-directional inclined angled plate, and saving production costs.
