Arc-shaped reinforced pressure-resistant bulkhead structure capable of resisting underwater explosion impact bending

Abstract

The invention discloses an arc-shaped reinforced pressure-resistant bulkhead structure capable of resisting underwater explosion impact bending, and belongs to the technical field of ship structure protection. The problem that an existing liquid tank inner plate is poor in protection force is solved. The protective structure is fixedly arranged on one side, close to a protective liquid tank, of the inner panel, the first reinforcing ribs are located on the side of the protective structure, the second reinforcing ribs are located on the side of the inner panel, and the protective structure comprises a plurality of arc-shaped supporting plates which are horizontally arranged and are in butt joint side by side from top to bottom; the first reinforcing rib and the protection structure are fixedly connected in a gapless mode, and the second reinforcing rib and the inner panel are fixedly connected in a gapless mode. According to the reinforced pressure-resistant bulkhead structure with the arc-shaped supporting plates, shock waves and bubble loads generated in the detonation process and fragment penetration can be more efficiently resisted, in addition, the reinforced pressure-resistant bulkhead structure is provided with a two-layer structure, and for fragments with higher quality and higher speed, the reinforced pressure-resistant bulkhead structure is equivalent to a two-layer bulkhead barrier, so that the service life of the bulkhead structure is prolonged, and the service life of the bulkhead structure is prolonged. And fragment energy is absorbed by the arc-shaped supporting plate and the inner panel in sequence, so that the water tightness of the liquid tank is enhanced.

Description

technical field [0001] The invention relates to an arc-shaped reinforced pressure-resistant bulkhead structure resistant to underwater explosion impact and bending, and belongs to the technical field of ship structure protection. Background technique [0002] When a ship performs missions at sea, it is inevitable that it will encounter attacks from enemy underwater anti-ship weapons, mainly including torpedoes and sea mines. The underwater part of the ship is broken and flooded, which poses a huge threat to the combat effectiveness and vitality of the ship. The "empty tank-liquid tank-empty tank" protective structure is the main defense form for large ships to resist underwater contact explosions. The expansion chamber composed of the side shell plate and the tank shell plate is an empty space, which provides the deformation space for the side shell plate during the detonation process and releases the pressure of the detonation product; the liquid tank shell plate and the l...
