Ship anti-impact protection structure based on aluminum honeycomb optimization

Abstract

The invention provides a ship anti-impact protection structure based on aluminum honeycomb optimization, and the structure comprises a ship body outer plate, a ship body inner plate, a ship body girder, a ship body solid rib plate, an inner protection structure and an outer protection structure; a plurality of small cabins are enclosed by the ship body outer plate, the ship body inner plate, the ship body girder and the ship body solid rib plate, and the plurality of small cabins are filled with the inner protection structure; outer protection structures are added on the hull outer plate in blocks; the inner protection structure comprises a plurality of inner protection aluminum honeycomb blocks, a liquid circulation hole is formed in the center of each inner protection aluminum honeycomb block, and through groove openings are formed in the two side faces, the upper surface and the lower surface of each inner protection aluminum honeycomb block. Each inner protection aluminum honeycomb block is formed by arranging and extruding a plurality of honeycomb plates in parallel, and the shape of each inner protection aluminum honeycomb block is matched with that of the corresponding small cabin; and the outer protection structure is an aluminum honeycomb plate which is formed by transversely and longitudinally overlapping. By means of the capability of absorbing underwater explosion impact through crushing deformation of the aluminum honeycomb, the protection capability and vitality of the ship can be improved.

Description

technical field [0001] The invention belongs to the field of ship protection, in particular to a ship anti-shock protection structure based on aluminum honeycomb optimization. Background technique [0002] Underwater explosions can cause serious damage to underwater structures such as ships, and the shock waves and pulsating bubbles generated by underwater explosions will seriously threaten the vitality and combat capabilities of underwater structures such as ships. How to improve the protection ability of the underwater ship structure has become an important research direction in the field of national defense. When the ship structure is subjected to a far-field underwater explosion, the shock wave has a very short action time and a large pressure peak, which will cause the ship to suffer The harsh impact environment will bring threats to the ship's outer plate structure, shipboard equipment and shipboard personnel. In the near-field and contact explosion environment, shock...

How to improve the protection ability of the underwater ship structure has become an important research direction in the field of national defense. When the ship structure is subjected to a far-field underwater explosion, the shock wave has a very short action time and a large pressure peak, which will cause the ship to suffer The harsh impact environment will pose a threat to the ship's outer plate structure, shipboard equipment and shipboard personnel

In near-field and contact explosion environments, shock waves and bubbles will pose a great threat to the vitality of the ship. After the shock wave, high-temperature and high-pressure bubbles will be generated, which will cause local large deformation, cracks and even damage to the overall structure of the ship. Serious threat to the life force of the ship and the safety of personnel
