Embodiment Construction

[0012] The present invention is based on a ship with an inclined double bottom arc bilge, which includes a flat outer bottom 1 and a flat inner bottom 3 arranged in parallel at the bottom of the ship. Such as Figure 4 As shown, the flat outsole 1 and the flat insole 3 are respectively connected to the sloping outsole 21 and the sloping insole 23 which are arranged in parallel and whose inclination angle A extends toward the side 7 at the same time. Figure 4 Among them, the inclined inner and outer bottoms adopt a parallel design, the inclined outer bottom 21 is connected with the side 7 through the arc-shaped bilge part 2, the inclined inner bottom 23 is connected with the inner shell 4 through a straight-line inclined bottom plate 5, and in the straight-line inclined The upper end of the bottom plate 5 is connected with a side girder 8 perpendicular to the side, and the lower end is provided with a bottom girder 6 perpendicular to the sloping inner bottom 23 and the sloping...

Abstract

The invention discloses a ship based on an oblique double-bottom arc-shaped bilge. The ship comprises a flat outer bottom (1) and a flat inner bottom (3) which are arranged at the bottom of the ship in parallel. The flat outer bottom (1) and the flat inner bottom (3) are respectively connected with an oblique outer bottom (21) and an oblique inner bottom (23) which are arranged in parallel and extend towards a broadside (7). The inclination angles of the oblique outer bottom and the oblique inner bottom are larger than 5 degrees but smaller than 25 degrees. The oblique outer bottom (21) and the broadside (7) are in transition connection through the arc-shaped bilge (2) which is tangent to the oblique outer bottom (21) and the broadside (7) respectively. The oblique inner bottom (23) is connected to an inner shell on the inner side of the broadside (7) through an oblique baseplate (5) at an inclination angle B. The B satisfies the condition that (45+A) degrees < B< (65+A) degrees. Through transition connection of straight lines and arcs and reasonable design of ends, loads are effectively transmitted, stress concentration is reduced, and structural strength is improved.

Description

technical field [0001] The invention relates to the technical field of shipbuilding, and more specifically relates to the improvement of the connection mode between the double bottom and the side of the double bottom ship. Background technique [0002] Such as figure 1 with figure 2 The ship shown is designed with a horizontal double bottom, the flat outer bottom 1 and the flat inner bottom 3 are arranged in parallel; the bottom girder 6 is arranged between the flat outer bottom 1 and the flat inner bottom 3 . Among them, the flat outer bottom 1 is connected to the side 7 through the bilge part 2 of the arc transition; and the flat inner bottom 3 is connected to the inner shell 4 parallel to the side 7 through a sloping bottom plate 5; Vertical and transverse bottom stringers 6 and side stringers 8 . [0003] The problem is that in order to achieve a certain functional requirement, the outer bottom in the ship design adopts a sloping design, which cannot be fully applied...
