Problems solved by technology

Wherein the existing double-hull submarine is provided with an outer non-pressure-resistant hull and an inner-layer pressure-resistant hull, but the non-pressure-resistant hull and the non-pressure-resistant hull of the conventional double-hulled submarine do not have explosion resistance Or the anti-knock performance is low, so its ability to resist the attack of underwater weapons is low, and the damage and deformation of the shell after being attacked are relatively large, which poses a great threat to the safety of submarines.

Embodiment Construction

[0048] The invention will be described in detail below in conjunction with specific embodiments.

[0049] The invention mainly relates to an anti-shock structure of a pyramid lattice interlayer of a submarine non-pressure-resistant shell, wherein the non-pressure-resistant shell refers to the outer shell of a double-hulled submarine.

[0050] Such as figure 1 As shown, in the present invention, according to the intensity and the probability that the different shell areas of the submarine suffer from the explosion impact, the shell of the submarine is divided into four areas, including the A / C area located on the left / starboard side of the submarine, and the area located on the top of the submarine. Area B and Area D located at the bottom of the submarine; generally speaking, Areas B and D are generally of higher strength and are less likely to be impacted by explosions, and Area B is connected to the superstructure, while Area D is the bottom structure, so it still retains its...

Abstract

The invention belongs to the field of submarine hull structure design, and relates to a submarine non-pressure hull pyramid lattice sandwich anti-impact structure and a design method thereof. The invention provides a structure and a design method for applying a pyramid lattice sandwich anti-impact structure to a weak area of a non-pressure shell. The method improves the anti-knock performance of the non-pressure shell by replacing a conventional non-pressure shell with a pyramid lattice sandwich shell plate structure without reducing the structural performance of the original non-pressure shell.

Description

technical field [0001] The invention belongs to the field of submarine hull structure design, and relates to a pyramid lattice interlayer impact-resistant structure of a submarine non-pressure-resistant shell and a design method thereof. Background technique [0002] As an important maritime combat force, submarines have always played an indispensable role in naval warfare. Due to the rapid development of weapon technology, the environment in which submarines are located is becoming increasingly severe. The anti-knock and anti-shock performance of submarines has become an important performance requirement. Wherein the existing double-hull submarine is provided with an outer non-pressure-resistant hull and an inner-layer pressure-resistant hull, but the non-pressure-resistant hull and the non-pressure-resistant hull of the conventional double-hulled submarine do not have explosion resistance Or the antiknock performance is low, so its ability to resist the attack of underwate...
