Embodiment Construction

[0025] In order to make the present invention more comprehensible, preferred embodiments are described in detail below with accompanying drawings.

[0026] like Figure 1 to Figure 7 As shown, a small waterplane area catamaran high load-bearing strong frame structure is used in the field of small waterplane area catamaran hull structure design. Column 3 structure, and set several diagonal braces perpendicular to the frame. When two diagonal braces 2 are set, it is in the form of oblique "π", and the upper "horizontal" of the "π" type structure is the brace 3, which is connected with the stern The inner sloping plate 1 is roughly parallel, and the lower two "verticals" are slanting braces 2, which are perpendicular to the sloping plate 1 on the inner side of the sloping platform. Except for the "π" type structure, the other strong frame structures in the sloping platform area can adopt conventional forms and be connected with The "π"-shaped structures are integrated into one, ...

Abstract

The invention discloses a high load-bearing efficiency strong frame structure of a small waterplane area catamaran, which includes three parts of the small waterplane area catamaran from top to bottom, which are respectively the uppermost sloping area, the middle pillar area and the lower part. The transition area is characterized in that the strong frame structure in the stern area is a π-shaped structure, the strong frame structure in the pillar area is an X-shaped structure or a Y-shaped structure, and the strong frame structure in the transition area is a K-shaped structure. The invention provides a new type of steel frame structure with high load-bearing efficiency, which solves the problem of minimizing the weight of the structure, bearing a larger load and producing smaller deformation than the conventional strong frame structure.

Description

technical field [0001] The invention relates to a high load-bearing strong frame structure of a small waterplane area catamaran, belonging to the technical field of ship frame design. Background technique [0002] Small waterplane area catamaran is a new type of ship with excellent performance, but its large width not only increases the deck layout area, but also makes the structural weight account for a large proportion of the empty ship's weight. With the enlargement of this type of ship, the huge transverse total load it bears will always be transmitted to the deck and the superstructure above the deck, so that the structural parts of the deck and superstructure need to be larger in size, which in turn brings greater structural weight. According to the design experience and research conclusions, the key to solving this problem is to improve the load-bearing efficiency of the transverse strong frame structure below the deck, so that it can bear most of the total transvers...
