Embodiment Construction

[0040] In the following, the present invention will be more clearly and completely described by way of embodiments in conjunction with the accompanying drawings, but the present invention is not limited to the scope of the described embodiments.

[0041] Before arranging the longitudinals of the hull surface outer plating, it is necessary to analyze the curvature variation of the outer plating. For general civil ships, since the engine room is arranged at the stern and the propeller is installed at the stern, the line shape change of the stern is much larger than that of the bow, that is, the curvature of the outer plate is much larger at the tail than at the bow. As far as the ribs of the head and tail are concerned, the lower part of the tail rib line changes more than the upper part, while the head rib line changes more smoothly up and down. The method for arranging the longitudinal bones of the curved outer plate of the hull in the present invention takes the arrangement o...

Abstract

The invention discloses an arrangement method for shell plate longitudinal bones of a hull curved surface. The arrangement method for the shell plate longitudinal bones of the hull curved surface comprises the following steps that (1), a longitudinal main component is selected; (2), with the longitudinal main component as the standard, hull frames are divided according to an equal arc length towards the two sides of the longitudinal main component and a plurality of longitudinal bone track lines are formed; and (3), the shell plate longitudinal bones are mounted according to the longitudinal bone track lines, included angles between webs of the shell plate longitudinal bones and a shell plate are not smaller than 75 degrees, and twist angles of the shell plate longitudinal bones are not larger than 1 degree / meter. According to the arrangement method for the shell plate longitudinal bones of the hull curved surface, the shell plate longitudinal bones are not bent, and the longitudinal bone track lines are not provided with a sharp point, so that the method is beneficial to effective force transmission; a transition triangular plate is not needed, the on-site trimming and matching time is saved, and the production efficiency is improved; and meanwhile, the distances between the shell plate longitudinal bones are equal, the size is economical relatively, the material cost is saved, the ship weight is reduced, and standard requirements are met.

Description

technical field [0001] The invention relates to a method for arranging the longitudinals of the hull curved surface outer plate. Background technique [0002] At present, there are two mainstream methods for the arrangement of longitudinals on the outer plating of the hull surface: straight line method and broken line method. In the existing technology, such as figure 1 , figure 2 , image 3 and Figure 4 as shown, figure 1 It is the transverse section obtained by cutting the hull in the middle of the hull with a plane perpendicular to the length of the hull. The straight line method is to cut the hull with a plane perpendicular to the transverse section of the hull and at a certain angle with the horizontal plane. ', also known as the track line of the longitudinal bone of the outer plate 11', the projection of the track line of the longitudinal bone of the outer plate 11' on the shape line diagram of the hull rib is a straight line, and the longitudinal bones of the ...
