Abstract

The invention relates to an explosion venting bulkhead structure with unequal intensity of a naval vessel cabin. The explosion venting bulkhead structure consists of an explosion venting plate, reinforcing ribs and corner connecting structures with unequal intensity, wherein the explosion venting plate is used for being damaged rapidly when an explosion occurs in the cabin to release pressure in the cabin; the reinforcing ribs are arranged on the inner side of the cabin, and are used for supporting the explosion venting plate and guaranteeing the residual intensity of a vessel body after the explosion venting plate is damaged; and the corner connecting structures with unequal intensity are arranged between the explosion venting plate and a strong bulkhead structure of the cabin, and are used for connecting the explosion venting plate and the strong bulkhead structure of the cabin, and guaranteeing that damage occurs on one side of the explosion venting plate when the explosion occurs in the cabin. Under the load of the explosion in the cabin of the naval vessel, the structure can be rapidly damaged to relieve pressure, so that the intensity and the energy of explosion products are dissipated through spatial distance and volume attenuation, the pressure of quasi-static air pressure is dispersed and reduced, the situation that the strong bulkhead structure of the cabin is integrally destroyed is avoided, and the residual intensity of the naval vessel structure is greatly improved.

Description

technical field

[0001] The invention relates to a ship protection structure, in particular to a ship cabin of unequal strength which can be quickly damaged when a shock wave and a quasi-static pressure load are generated by an explosion in the cabin of the ship, release the pressure in the cabin, and reduce the damage degree of the strong bulkhead structure of the cabin. Explosion vent bulkhead structure. Background technique

[0002] With the rapid development of modern anti-ship weapons, various high-performance semi-armor-piercing anti-ship weapons have become the main threat to the broadside of surface ships above the waterline. According to DeMar's empirical formula, taking the famous American Harpoon (AGM-84A) missile as an example, when the missile warhead hits the broadside at a speed of 340m / s, it needs 79.3mm thick steel armor to resist its kinetic energy armor penetration. Modern surface ships generally use thin-walled structures. Therefore, anti-ship weapons pen...
