Embodiment Construction

[0017] see figure 1 , figure 2 and image 3 As shown in Fig. 1, mark 1 of the outer plate of the bow that needs to be staked out is drawn at a ratio of 1:1, and the projected part drawing of its transverse view is created as a separate file and saved in .DXF format. Import the part drawing file in .DXF format into the hull design software Tribon M3 system, and store it in a specific sub-library.

[0018] Start the Curved Hull module program of the hull surface design program, create and call the transverse view, longitudinal view and water plane view of the 3D model of the outer plate seam of the hull outer plate 2 . Move and adjust the sub-picture of the bow outer plate mark 1 to the projected position of the hull outer plate 2 where it is located in the transverse view of the seam of the hull outer plate. Merge the sub-graph of the bow outer plate mark 1 into the sub-graph of the transverse view of the hull outer plate 2.

[0019] Using the function of creating plate se...

Abstract

The invention discloses a lofting method for hull plate marking parts. The method includes: marking parts on the ship body stem outer plate, drawing a stem outer plate mark needing to be lofted according to the proportion of 1: 1, independently storing a projection part graph of a transverse view of the stem outer plate mark in a sub-graph library, and moving and adjusting the mark sub-graph in the transverse view of the ship body outer plate seam to the projection position of the ship body outer plate where the mark sub-graph is located; enabling the stem outer plate mark to be subjected to subgraph merging into a subgraph of a transverse view of the ship body outer plate; carrying out section-by-section lofting on the outline line of the bow column outer plate mark, carrying out section-by-section inspection on the outline edge line of the bow column outer plate mark, obtaining a smooth and complete part graph, and finally carrying out steel plate cutting blanking or paper mold manufacturing on an actual part and mounting the actual part on an actual position. By means of the method, outer plate marking lofting three-dimensional model positioning and shaping can be conducted on the ship bow, the lofting result is completely consistent with the expected design effect, and the lofting result can be obtained within the shortest time.

Description

technical field [0001] The invention relates to the field of ship design, in particular to a lofting method for marked parts on the outer plate of a hull, and marks the parts on the outer plate of the hull stem. Background technique [0002] At present, three-dimensional hull design software is generally used to realize the lofting work of the logo on the outer panel of the hull, such as Tribon M3 and AVEVA Marine design software, but when it is necessary to attach the logo to the mid-span bow outer panel of the hull, it is When the bow of the hull is on the bow, the existing hull design software cannot realize the marking, modeling and stakeout work due to its own defects in the program. At this time, the lofting designer performs semi-manual lofting on the marked part by marking the corresponding positional relationship of each point in each view. This lofting method takes a long time, and the precision of the part after lofting is difficult to control. There are certain ...
