Transverse arc-shaped bulkhead anti-explosion protection structure for broadside of ship

Abstract

The invention provides a transverse arc-shaped bulkhead anti-explosion protection structure for the broadside of a ship, belonging to the field of ship protection. The structure of the invention overcomes the problems that an existing bulkhead protection structure is insufficient in protection optimization and poor in protection capacity. The structure comprises a liquid tank inner plate, a watertight bulkhead and a plurality of arc-shaped plates, wherein the liquid tank inner plate, the watertight bulkhead and the arc-shaped plates are arranged between and connected with bulkheads, the arc-shaped plates are welded between the wired liquid tank inner plate and the watertight bulkhead and transversely arranged in the length direction of the ship, the ends of the arc-shaped plates are connected with a transverse bulkhead, the liquid tank inner plate and the watertight bulkhead are integrally welded to a liquid tank outer plate, the liquid tank outer plate and tank section outer plates are connected through a plurality of rib plates, and a plurality of explosion venting holes are formed in the rib plates. The structure is mainly used for protection of the broadside of a large ship.

Description

technical field [0001] The invention belongs to the field of ship protection, in particular to an anti-explosion protection structure for a transverse arc-shaped bulkhead on the side of a ship. Background technique [0002] The vitality of a ship under the impact load of an underwater explosion is an important link that must be considered in its structural design. At this stage, with the continuous development of guided weapons, such as self-propelled mines, self-guided mines, missile mines, self-guided depth charges, etc. With the emergence of new weapons, the threats faced by surface ships are more complex and unpredictable. As a weapon of modern naval warfare, surface ships have always been the key targets of various countries. Countries pay great attention to their protective performance and the design of passive protective structures, and have always adopted the design idea of ​​multi-cabin structures. [0003] Early ships had little consideration for ship protection c...

Problems solved by technology

Traditional flexible supports are usually arranged vertically. Judging from the numerical calculation results at this stage and the damage mode of vertical arc supports in model tests, the energy absorption efficiency of the upper and lower ends is not high.
