Method for constructing scale model of explosion ship in warhead cabin of anti-ship missile

Abstract

The invention discloses a method for constructing an explosion ship scale model in an anti-ship missile warhead cabin, and belongs to the technical field of explosion damage and protection. The method comprises the following steps: determining a ship cabin structure according to a constrained explosion type, and determining air parameters: initial pressure, initial density and adiabatic index; determining material parameters including density, shear modulus and yield stress according to ship cabin material parameters, determining ship cabin geometric parameters according to the ship cabin size, setting corresponding parameters according to a similarity principle, obtaining a ship model scaling formula in combination with a dimension tool, and constructing a scaling model according to the scaling formula. The mechanical characteristics of the ship damaged by explosion in the full-size anti-ship missile warhead cabin are predicted through the scale model, and then the anti-explosion performance of the ship and the damage effect of the anti-ship missile warhead on the ship are evaluated by analyzing and measuring the dynamic load. According to the method, the experiment cost can be saved, the personnel safety is improved, and a convenient, rapid and reliable reference basis is provided for design and optimization of related weapon warheads or protective structures and the like.

Description

technical field [0001] The invention relates to a method for constructing a scaled model of an explosive ship in an anti-ship missile warhead cabin, and belongs to the technical field of explosion damage and protection. Background technique [0002] With the enhancement of naval combat strength, surface ships have been widely used in combat. Ships will be blasted by airborne anti-ship weapons such as anti-ship missiles when performing missions at sea. On the one hand, from the perspective of anti-ship missiles, it is necessary to achieve better armor-piercing and explosive effects, and improve the damage power of the warhead. On the other hand, from the perspective of ships, it is necessary to achieve better protection and anti-knock performance and improve the effect of damage protection. Through scaled model experiments, low cost, high operability, and repeatable tests can be carried out. [0003] The pressure load of the explosion in the cabin is obviously different fr...

Problems solved by technology

[0007] In view of the difficulty and high cost of the full-scale test of the ship model exploded in the anti-ship missile cabin, the purpose of the present invention is to provide a method for constructing a scaled model of the ship exploded in the cabin of the anti-ship missile warhead. The scaled model of the ship exploded in the warhead of the warship missile is used to predict the mechanical characteristics of the ship damaged by the explosion in the warhead of the full-scale anti-ship missile through the scaled model, and then by analyzing and measuring the dynamic load, the anti-knock performance and anti-knock performance of the ship are evaluated.
