An optimized anti-shock protection structure for ships based on aluminum honeycomb

Abstract

The invention provides an anti-shock protection structure of a ship based on aluminum honeycomb optimization, including hull outer panels, hull inner panels, hull girders, hull solid floors, inner protective structures and outer protective structures, hull outer panels, hull inner Plates, hull girders and solid floors of the hull form multiple small cabins, and the inner protective structure is filled in multiple small cabins; the outer protective structure is added to the outer plate of the hull in blocks; the inner protective structure includes several inner protective aluminum honeycomb blocks , there is a liquid circulation hole in the center of each inner protective aluminum honeycomb block, and through slots are opened on both sides and upper and lower surfaces of each inner protective aluminum honeycomb block; the inner protective aluminum honeycomb block is arranged in parallel by several honeycomb panels It is extruded, and the shape of each inner protective aluminum honeycomb block is adapted to the shape of the corresponding small cabin; the outer protective structure is an aluminum honeycomb panel stacked horizontally and vertically. Through the crushing and deformation of the aluminum honeycomb, the ability to absorb the impact of underwater explosions, the invention can improve the protection ability and vitality of the ship.

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
