Description

Technical fields:

[0001] This invention relates to the field of ship window design, and in particular to a method for manufacturing ship windows. Background technology:

[0002] Due to aesthetic requirements, the forewall of passenger roll-on / roll-off ships is often designed in an arc shape and has many windows (usually flat windows). In the traditional ship design process, in this case, the interior design department usually provides the hull design department with the location data and opening dimensions of the window openings (the openings required for window installation) through a written agreement. The hull design department then uses this agreement to design the openings and markings for the window openings.

[0003] Passenger roll-on / roll-off (Ro-Ro) ships have high requirements for the precision and aesthetics of the installation rings. Using traditional design methods, the forewall is curved, and the unfolded window openings are approximately parallelogram-shaped. The internal angles or inclinations are calculated manually by the interior design department, which carries the risk of calculation errors. Furthermore, when designing the forewall window openings based on the agreement drawings, the openings in the AM design software are not visible in the model, making it impossible to check for interference between the curved openings in the hull compartment and the windows in the interior compartment. In other words, the window design in the interior compartment and the forewall opening design in the hull compartment are carried out independently, without mutual checking, easily leading to problems such as mismatches between windows and outer plating openings.

[0004] There is an urgent need for a method for manufacturing ship windows, which would help solve the technical problem that the lack of design software in the current technology makes it impossible to lay out window dimensions on curved surfaces, resulting in distortion during the size production process. Summary of the Invention:

[0005] In one embodiment, the present invention provides a method for manufacturing ship windows, which constructs a parallelogram by using the center point of the window opening, the waterline, and the longitudinal section line, and finally performs lofting manufacturing. This helps to solve the technical problem in the prior art that the lack of design software makes it impossible to loft window dimensions on curved surfaces, resulting in distortion during size manufacturing.

[0041] like Figures 1 to 4 As shown, in one embodiment, the present invention provides a method for manufacturing a ship's front window, the method comprising:

[0042] Determine the center point of the window opening based on the dimensions of the window opening on the hull;

[0043] A spatial cross line is formed by constructing water lines and longitudinal sections based on the center point of the window opening;

[0044] The waterline and the longitudinal section line are offset to form a parallelogram plane;

[0045] Ship windows are manufactured according to the dimensions of the parallelogram plane.

[0046] This embodiment provides a specific implementation method for manufacturing ship windows. The window size is a point in space within the overall ship coordinate system. This data can be directly obtained from modeling software such as AM. This center point has three-dimensional coordinates X, Y, and Z. These coordinates are drawn on the ship's curved surface according to the waterline and section lines. The Y and Z values ​​are used to draw along the ship's curved surface, and then an offset is performed. At this point, the curved surface is no longer considered, and the window is transformed into a plane. After offset, a parallelogram plane is formed. Because the glass window after the opening is transformed into a plane, and its location is at the four vertices of the parallelogram, it can be used for material cutting and ordering.

[0047] In one embodiment, the dimensions include side length and angle, as well as bevel.

[0048] In one embodiment, after the step of manufacturing the ship window according to the dimensions of the parallelogram plane, the method further includes:

[0049] An opening is made on the arc-shaped front wall of the perforated plate of the front window of the hull compartment;

[0050] The ship's window, manufactured to the specified dimensions, is installed on the opening in the curved front wall.

[0051] This embodiment provides a specific implementation method for installing openings on the hull.

[0052] In one embodiment, the opening on the arc-shaped front wall of the perforated plate of the front window of the hull compartment is made by creating opening line data or opening pattern on the arc-shaped front wall.

[0053] In one embodiment, after the step of offsetting the waterline and the longitudinal section line to form a parallelogram plane, the method further includes:

[0054] Fillet the four vertices of the parallelogram plane.

[0055] In one embodiment, the opening on the arc-shaped front wall is made by making the opening according to the distance from the midship and the waterline, and the dimensions of the rounded corners of the four apex corners are provided to make the apex corner arc dimensions.

[0056] This embodiment provides a specific implementation method for making holes on the hull in conjunction with the above-mentioned window, and then forming matching holes with matching rounded corners.

[0057] In one embodiment, a surrounding reinforcement structure is arranged through an opening in the arcuate front wall.

[0058] In one embodiment, the ship window manufacturing method is used for hull windows of passenger roll-on / roll-off ships.

[0059] The overall process can be summarized as follows:

[0060] 1. Modeling the front window planar perforated plate

[0061] (a) Based on the window opening location data and opening dimensions provided by the interior design department, determine the position of the center point of the window opening on the curved front wall, and draw the center horizontal and vertical cross lines.

[0062] (b) Offset the center waterline of the window opening vertically and horizontally according to the window opening size, and offset the longitudinal cross lines horizontally. Take the intersection of the four offset lines to construct a parallelogram-shaped flat plate. The dimensions of this plate should conform to the window opening size, and the four corner points should fit the curved front wall.

[0063] (c) Feed back the completed front window plane opening plate model to the interior design department for verification. If it does not meet the requirements, repeat the previous steps until the window layout requirements are met.

[0064] 2. Take a plan view of the front window opening plate of the interior room, and extract the side length, angle or inclination data of the parallelogram for window ordering;

[0065] 3. The hull compartment is designed with perforated plates according to the front window plane, and holes are made on the arc-shaped front wall. The perforation data or perforation pattern is made, and the surrounding reinforcement structure is arranged.

[0066] Beneficial effects:

[0067] This method adds an intermediate medium plate during the design process, which effectively avoids the situation where windows and window openings cannot be inspected during the design process. At the same time, it can avoid the situation where windows and window openings do not match during on-site window installation, improve the accuracy of the designed products, reduce on-site adjustments, and shorten window installation time.

[0068] The above embodiments are merely exemplary embodiments of the present invention and are not intended to limit the present invention. The scope of protection of the present invention is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to the present invention within its spirit and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of the present invention.
