The specific embodiment

Below in conjunction with drawings and Examples technical scheme of the present invention is further described.

The naval vessel shell need have two big functions simultaneously, and the one, the shape function is guaranteed the complex appearance on naval vessel to make the naval vessel have good hydrodynamic force and hydrostatic power performance; The 2nd, structure function can guarantee that the various structural strengths on naval vessel require and performance requriements.How to cast aside naval vessel agent structure design-calculated traditional thought, suppose that above-mentioned shape function, structure function no longer born by single shell, but realize the basic point of departure of design philosophy of the present invention that Here it is respectively by the different member of two classes.

Fig. 1 is for adopting double-layer modularized design-calculated outer hull of ship structural representation among the present invention.As shown in Figure 1, the shell of naval vessel main body is double-deck, and the hull skin is an adhesion layer 1, in order to guarantee the complex appearance of hull, makes the naval vessel have good fluid water tractive performance.Adhesion layer 1 can adopt elasticity height, wear-resisting, shock-resistant, easy processing, easily shaping, the preparation of low-cost lightweight composite materials.The hull internal layer is a body layer 2, in order to guarantee the various structural strengths and the usage space on naval vessel, also is the carrier of adhesion layer 1 simultaneously.Body layer 2 can adopt the high steel of intensity, is put together by the flat unit module of standard sequential.Like this, the appearance of body layer is exactly well-regulated polyhedron.

The method of designing of naval vessel of the present invention main body double-layer modularized structure is specific as follows:

1, according to the shape and structure feature on naval vessel, the naval vessel main body being divided into several regions, generally is that the boundary divides with the transcerse bulkhead.Fig. 2 is the shell in a zone marking off, and Fig. 3 is the shell shape of this front and back end, zone.

2, at each zone, at first require to provide the height on each layer deck, comprise tank top plate, platform, each layer deck, upper deck, weather deck etc., and to require the diff-H between them be the integral multiple of production-release design modulus.

3, on two end faces in each regional front and back end, upwards make vertical line and last layer deck or platform from each layer deck (platform) and the intersection point of bench section line style and intersect.Connect all intersection points and obtain a broken line body lines, this broken line is following outside plate body layer, and the section at the two ends of the main body that this is regional is made up of some rectangles.Division methods as shown in Figure 4, dash area is the section shape of adhesion layer at regional two ends among Fig. 4.

4, for the very big side of a ship top of flare and the turn of the bilge of becoming thin, the section shape at regional two ends can adopt skew lines to be divided into, and the main body two ends section that makes this place in echelon or triangle.See Fig. 4.

5, divide according to above-mentioned principle, can draw the body layer in the zone that constitutes by flat member, its outer adhesion layer that needs that is.Figure 5 shows that the body layer in the zone shown in Figure 2 that is made of flat member, Fig. 6 is the adhesion layer at A place among Fig. 4.

Shipyard can adopt conventional plane grillage production technology to produce body layer.Adhesion layer adopts elasticity height, wear-resisting, shock-resistant, easy processing, easily is shaped, low-cost light-duty composite wood (as the polyester of foaming etc.), combine by certain measure and body layer, in conjunction with method can adopt screw connection or adhesives.

The naval vessel body layer adopts the flat unit module to form among the present invention, helps realizing mechanization production, shortens shipbuilding period, reduces cost, and the main body internal layer of rule makes that the local structure design is simple and direct simultaneously, arrangement convenience.Adhesion layer adopts composite material to make, and is easy to forming work, can pass through the area of computer aided moulding, also can make adhesion layer have functions such as explosion-proof, demagnetization, has so both guaranteed the requirement of naval vessel to line style, has avoided heavy outside plate processing work again.In case damage, repair also very convenient, as long as that piece adhesion layer that will damage is simply changed.
